1.The remorte controller can be used to switch between "high" and "low".2.The air flow is set to "standerd" before leaving the factory. It is possible
to switch between "standerd ESP" and "high ESP" by changing the terminals in the indoor unit electrical box.
3.The external static pressure indicates the characteristics of the fan when a suction panel (optional accessory)and a canvas for the suction panel (optional accessory) are incorporated into the main unit (with a long-life filter).

SYMBOLS: NOTE:MCA : MIN. CIRCUIT AMPS (A) 1. RLA is based on the following conditions.
Power Supply: 50Hz 230VCoolingIndoor temp.: 27°CDB/19°CWBOutdoor temp.: 35°CDB.
2. Voltage range.Units are suitable for use on electrical systems where voltage supplied to unit terminal is not below or above listed range limits.
3. Maximum allowable voltage variation between phases is 2%.4. Select wire size based on the value of MCA.5. MCA represents maximum input current.
MFA represents capacity which may accept MCA.6. Instead of fuse, use circuit breaker.7. MFA is used to select the circuit breaker and the ground fault
circuit interrupter (earth leakage circuit breaker).8. Be sure to install an earth leak detector. (One that can handle
higher harmonics.)(This unit uses an inverter, which means that it must be used an earth leak detector capable handling high harmonics in order to prevent malfunctioning of the earth leak detector itself.)

2. INTRODUCTION1. This series uses R410A new refrigerant. Be absolutely sure to
comply with “7. PRECAUTIONS ON REFRIGERANT PIPING”, because even greater caution is needed to prevent impurities from entering R410A (mineral oils and water).
2. The design pressure is 4.0MPa (2.8MPa for R22), which means that piping may be thicker than conventionally, so please refer to “7. PRECAUTIONS ON REFRIGERANT PIPING”.
3. This is a mixed refrigerant, so charge as a liquid when adding refrigerant. (If charged as a gas, the composition of the refrigerant may change, preventing normal operation.)
4. The indoor unit must use R410A. See the catalog for indoor unit and BP unit models which can be connected. (Normal operation is not possible when connected to other units.)
5. The power supply of this series is single-phase, 220 to 240V (50Hz) in the model ~EV1A, single-phase, 220 to 230V (50/60Hz) in the model ~EVM, single-phase, 220V (60Hz) in the model ~EVLT.

3. BEFORE INSTALLATION<Transporting the Unit>As shown in figure 2, bring the unit slowly. (Take care not to let hands or things come in contact with rear fins.)
(Refer to figure 2)1. Air outlet grille2. Intake hole3. Corner4. Outdoor unit5. Handle6. Front7. Rear8. Always hold the unit by the corners, as holding it by the
side intake holes on the casing may cause them to deform.
Use only accessories and parts which are of the designated specifi-cation when installing.
4. SELECTING INSTALLATION SITE(1) Select an installation site where the following conditions are
satisfied and that meets with your customer’s approval.• Places which are well-ventilated.• Places where the unit does not bother next-door neighbors.• A locations where small animals will not make nests in the unit.• Safe places which can withstand the unit’s weight and vibration
and where the unit can be installed level.• Locations not exposed to rain.• A locations where there is enough space to install the unit.• Places where the indoor and outdoor unit’s piping and wiring
lengths come within the allowable ranges.• A location where there is no risk of flammable gas leaking.
(2) If the unit is installed in a location where it might be exposed to strong wind, install as per figure 3.• 5m/sec or more strong wind blown against the outdoor unit’s air
outlet causes the outdoor unit to deteriorate in air capacity and suck in the air blown out of its air outlet (short circuit), and the fol-lowing effects may result.
• Drop in performance.• Increased frost formation in heating mode.• Shutting down due to increase in pressure.
• If very strong wind blows continuously on the side of the outdoor unit with the outlet vent, the fan may turn in reverse at high speed and break, so install as per figure 3.
(Refer to figure 3)1. Turn the air outlet side toward the building’s wall, fence or
windbreak screen.2. Air inlet grille3. Ensuring there is enough space for installing the unit.4. Set the outlet side at a right angle to the direction of the
wind.5. Strong wind6. Blown air
(3) In installing the unit in a place frequently exposed to snow, pay special attention to the following:• Elevate the foundation as high as possible.• Attach the snow hood (field supply).• Remove the rear inlet grille to prevent snow from accumulating
on the rear fins.
(4) The outdoor unit may short circuit depending on its environment, so use the louvers (field supply).
(5) The refrigerant gas (R410A) is a safe, non-toxic and non-flam-mable gas, but if it leaks into the room, the concentration may exceed tolerance levels, especially in small rooms, so steps need to be taken to prevent refrigerant leakage. See the equipment design reference for details.

Caution
To the electrician• Do not operate until refrigerant piping work is completed.
(If operated before complete the piping work, the compressor may be broken down.)
• Be sure to install an earth leakage circuit breaker.(This unit uses an inverter, so install the earth leakage circuit breaker that be capable of handling high harmonics in order to prevent malfunctioning of the earth leakage circuit breaker itself.)
6-1 Wiring connection example for whole system• Electrical wiring work should be done by a certified professional.• Follow the “Electrical wiring diagram face plate” when carrying out
any electrical wiring.Only proceed with wiring work after blocking off all power.
• Make sure the ground resistance is no greater than 4Ω . • Attach a ground-fault circuit interrupter.• Ground the indoor and outdoor units.• Do not connect the ground wire to gas pipes, sewage pipes, light-
ning rods, or telephone ground wires.• Gas pipes: can explode or catch fire if there is a gas leak.• Sewage pipes: no grounding effect is possible if hard plastic
piping is used.• Telephone ground wires and lightning rods: dangerous
when struck by lightning due to abnormal rise in electrical poten-tial in the grounding.
• Use copper wire.• When doing the electrical wiring, always shut off the power source
before working, and do not turn on the switch until all work is com-plete.
• This unit has an inverter, so it must be grounded in order to reduce noise and prevent it affecting other appliances, and also to release any electrical build-up in the unit case due to leaked cur-rent.
• Do not install a power-factor improving phase-advancing capaci-tor under any circumstances.(Not only will this not improve the power factor, but it might cause a fire.)
• Connect the wire securely using designated wire and fix it with attached clamp without applying external pressure on the termi-nal parts (terminal for power wiring, terminal for transmission wir-ing and earth terminal). See “6-3 How to connect the power supply wiring”.
• Left-over wiring should not be wrapped and stuffed into the unit.• To prevent the power wiring from being damaged by the knock
hole edges, put it in a wiring pipe or plastic tube to protect it.• Secure the wiring with the included clamp so that it does not come
in contact with the piping or shutoff valve. (See “6-3 How to connect the power supply wiring”.)
Caution
• Use a power wire pipe for the power supply wiring.• Outside the unit, make sure the weak electric wiring (i.e. for the
remote controller cord, between units, etc.) and the strong elec-tric wiring do not pass near each other, keeping them at least 50 mm apart.Proximity may cause electrical interference, malfunctions, and breakage.
• Be sure to connect the power wiring to the power wiring terminal block and secure it as described in “6-3 How to connect the power supply wiring”.
• Interunit wiring should be secured as described in “6-4 Inter-unit wiring connection procedure”.
• Secure wiring with clamp (accessory) to avoid contact with pip-ing.
• Make sure the wiring and the front panel do not stick up above the structure, and close the cover firmly.

<Precautions when laying power wiring>• Wiring of different thicknesses cannot be connected to the power
terminal block. (Slack in the power wiring may cause abnormal heat.)
• Use sleeve-insulated round pressure terminals for connections to the power terminal block. When none are available, connect wire of the same diameter to both sides, as shown in the figure.
Follow the instructions below if the wiring gets very hot due to slack in the power wiring.• For wiring, use the designated power wire and connect firmly,
then secure using the included clamping material to prevent out-side pressure being exerted on the terminal board.
• Use an appropriate screwdriver for tightening the terminal screws.A screwdriver with a small head will strip the head and make proper tightening impossible.
• Over-tightening the terminal screw may break it.
See the table below the tightening torque of the terminal screws.
6-3 How to connect the power supply wiring
Caution
Attach a ground-fault circuit interrupter.• A ground-fault circuit interrupter is required in order to prevent
electric shock and fires.
Caution
• The wiring should be selected in compliance with local specifi-cations. See the table above.
• Comply with IEC60245 as regards individual specifications for local power supply wiring.
• Use H05VV as the power supply wiring if a wiring conduit is being used.
• If a conduit cannot be used, then use H07RNF.• Always turn off the power before doing wiring work.• Grounding should be done in compliance with local laws and
regulations.• Attach a ground-fault circuit interrupter.
(This unit has an inverter, so an interrupter capable of handling high frequencies is needed to prevent malfunction of the inter-rupter itself.)
• As shown in figure 16, when connecting the power supply wiring to the power supply terminal block, be sure to clamp securely.
• Once wiring work is completed, check to make sure there are no loose connections among the electrical parts in the control box.
If small animals might enter the unit, block the knock holes with an appropriate material (field supply).

6-4 Interunit wiring connection procedure• Between indoor units in the same system, pass the wiring
between the units as shown in figure 17. (There is no polarity.)
(Refer to figure 17)1. Terminal block (X2M)2. Use balance type shield wire (with no polarity).3. BP unit4. Under no circumstances should 220-240V be con-
nected.
Precautions regarding the length of wiring between unitsExceeding the following limits may cause transmission malfunctions, so observe them.Max. wiring length Max. 200 mTotal wiring length Max. 300 m
Precautions regarding wiring between units• Do not connect 220-240V power wiring to terminals for the
interunit wiring. Doing so would destroy the entire system.• Wiring to the indoor unit should be wired to F1 and F2 (TO BP
unit) on the outdoor unit’s terminal block (X2M).• The interunit wiring should be secured inside the unit and then fin-
ished by being wrapped with tape at the same time as the on-site refrigerant piping, as shown in figure 18.
(Refer to figure 18)1. Liquid pipe2. Finishing tape3. Insulation material4. Interunit wiring5. Gas pipe
Note• The above wiring should be wired using 0.75 – 1.25 mm
2 shielded
(balance type) wiring. (See figure 16 for how to ground the shielded parts.)
• All interunit wiring is to be procured on site.
Caution
(Refer to figure 19)1. Branch2. Caution on branches in the wiring among BP units3. The following branches can not be performed
7. PRECAUTIONS ON REFRIGERANT PIPING
Caution
To the pipe-layer• Do not operate the unit with the transport clasp attached. This
can cause abnormal shaking or noise. See “5. PRECAUTIONS ON INSTALLATION” and “How to remove the transport clasp”.
7-1 Installation toolsUse the right parts to ensure tolerance and to prevent foreign matter for entering.
Gauge manifold, charge hose, etc.• Make sure to use installation tools that are exclusively used for
R410A installations to withstand the pressure and to prevent for-eign materials (e.g. mineral oils such as SUNISO and moisture) from mixing into the system.(The screw specifications differ for R410A and R407C.)
Vacuum pump• Use extreme caution to prevent pump oil from flowing back-
wards through the system when the pump is stopped.• Use a vacuum pump which can evacuate to –100.7 kPa (5Torr,
–755mmHg).
7-2 Selecting piping material• Use pipes that have no contaminants adhered to their inner surfaces
(such as sulfur, iron oxide, dust, cutting chips, oil and moisture). (It is desirable that adhered oil inside the piping is 30mg or less per 10m.)
• The wall thickness of the refrigerant piping should comply with local laws and regulations. The design pressure for R410A is 4.0MPa.
• Use the following material for the refrigerant piping. Material: Jointless phosphor-deoxidized copper pipe.
• Thickness and size: choose based on the piping size selection method on the “7-8 Air tight test and vacuum drying”.
• Make sure to use the separately sold refrigerant branch kit when branching the piping.
• Piping work should be done within the maximum length, height difference, and length after branches set out in “7-8 Air tight test and vacuum drying”.
• Install the refrigerant branch kit while observing the following con-dition and referring to the installation manual offered as an acces-sory of the kit.
(Refer to figure 20)1. Install the REFNET joint so it splits horizontally or vertically.2. Horizontal surface3. A-arrow view4. ±30° or less5. Level6. Vertical is also OK
7-3 Protection against contamination when installing pipes
• Wrap the piping to prevent moisture, dirt, dust, etc. from entering the piping.
• Exercise caution when passing copper piping through the through-holes and when passing them out to the outside.
7-4 Pipe connection• See “Shutoff valve operation procedure” in “7-8 Air tight test and
vacuum drying” regarding handling of the shutoff valve.• Only use the flare nuts included with the unit. Using different flare
nuts may cause the refrigerant to leak.• Be sure to perform a nitrogen blow when brazing.
(Brazing without performing nitrogen replacement or releasing nitrogen into the piping will create large quantities of oxidized film on the inside of the pipes, adversely affecting valves and compres-sors in the refrigerating system and preventing normal operation.)
Place Installation period Protection method
OutdoorMore than a month Pinch the pipe
Less than a monthPinch or tape the pipe
Indoor Regardless of the period
Installation Manual 85
Outdoor Units EDSG18-936
NoteThe nitrogen used when brazing while flowing the nitrogen should be
set to 0.02 MPa (0.2 kg/cm2: just enough to feel a breeze on your
cheek) with the decompression valve.• Do not mix any refrigerant other than that specified into the refrig-
erant system.• Do not mix air into the refrigerant system.
Caution
Do not use a flux when brazing the refrigerant pipe joints. Use phosphor copper brazing (BCuP-2: JIS Z 3264/B-Cu93P-710/795: ISO 3677) which does not require flux.(Using a chlorine flux may cause the pipes to corrode, and if it contains fluoride it may cause the refrigerant lubricant to deterio-rate, adversely affecting the refrigerant piping system.)
(Refer to figure 21)1. Refrigerant pipe2. Location to be brazed3. Regulator4. Nitrogen5. Manual valve6. Taping
7-5 Connecting the refrigerant piping• The local interunit piping is connectable in four directions.
(Refer to figure 22)1. Front panel2. Pipe outlet panel3. Backward4. Sideways5. Downward6. Pipe outlet panel screw7. Forward8. Screw for front panel
• When connecting in a downward direction, make four round holes using a 6-mm iameter drill in the central section around the knock hole and open the knock hole.
(Refer to figure 23)1. Dril2. Center area around knockout hole3. Knockout hole4. Slit
• After knocking out the knock-out, it is recommended to apply repair paint to the edge and the surrounding end surfaces to pre-vent rusting.
(Refer to figure 24)1. Bottom frame2. Interunit piping
NoteCutting out the two slits makes it possible to install as shown in fig-ure 24. (Use a metal saw to cut out the slits.)
<Precautions when connecting pipes>• Please refer to the Table 1 for the dimensions for processing
flares.• When connecting the flare nut, coat the flare both inside and out-
side with refrigerating machine oil and initially tighten by hand 3 or 4 turns before tightening firmly.
• Please refer to the Table 1 for the tightening torque. (Too much tightening will end up in splitting of the flare.)
Table 1
• If a torque wrench is not available, there is a place where the tight-ening torque will suddenly increase if a normal wrench is used to tighten the flare nut.From that position, further tighten the flare nut the angle shown below.
• After all the piping has been connected, use nitrogen to perform a gas leak check.

Precautions for connecting pipes• Be careful not to let the interunit piping come into contact with the
compressor terminal cover.Adjust the height of the insulation material on liquid pipe when it has the possibility of getting in contact with the terminal. Also make sure that the interunit piping does not touch the mounting bolt of the compressor.
(Refer to figure 27)1. Terminal cover2. Compressor3. Corking, etc.4. Insulation material5. Bolts6. Interunit piping
• If installing the outdoor unit higher than the indoor unit, caulk the space around insulation and tubes because condensation on the check valve can seep through to the indoor unit side.
[Preventing foreign objects from entering]• Plug the pipe through-holes with putty or insulating material (pro
cured locally) to stop up all gaps, as shown in figure 26.(Insects or small animals entering the outdoor unit may cause a short in the control box.)
(Refer to figure 26)1. Putty or insulating material2. (field supply)
7-6 Heat insulation of piping• If you think the humidity inside the ceiling might exceed 30˚C and
RH80%, reinforce the insulation on the cooling piping. (At least 20 mm thick) (Condensation may form on the surface of the insu-lation.)
• Be sure to insulate the interunit piping (liquid and gas-side) and the refrigerant branch kit. (Not insulating them may cause leak-ing.)
(The highest temperature that the gas-side piping can reach is around 120˚C, so be sure to use insulating material which is very resistant.)
Caution
For local insulation, be sure to insulate all the way to the pipe con-nections inside the machine.Exposed piping may cause leaking or burns on contact.

7-8 Air tight test and vacuum dryingAfter doing the piping, perform the following inspections.
Be sure to use nitrogen gas. (See the figure (“Shutoff valve operation procedure”) for the location of the service port.)
[Procedure]Pressurize from the liquid pipes and gas pipes to 4.0 MPa (and not above 4.0 MPa). If there is not pressure drop over the next 24 hours, the equipment has passed the test.If the pressure drops, check for leakage positions. (Confirm that there is no leakage, then release nitrogen.)
Use a vacuum pump that can create a vacuum down to at least –100.7 kPa (5 Torr, –755 mmHg).
[Procedure]Operate the vacuum pump for at least 2 hours from both the liquid and gas pipes and decrease the pressure to at least –100.7 kPa. Leave at below –100.7 kPa for at least 1 hour and make sure that the vacuum gauge does not rise. (If it does rise, there is either still mois-ture in the system or a leak.)
Cases where moisture might enter the piping (i.e., if doing work during the rainy season, if the actual work takes long enough that condensation may form on the inside of the pipes, if rain might enter the pipes during work, etc.)After performing the vacuum drying for 2 hours, pressurize to 0.05 MPa (i.e., vacuum breakdown) with nitrogen gas, then depres-surize down to at least –100.7 kPa for an hour using the vacuum pump (vacuum drying). (If the pressure does not reach at least –100.7 kPa even after depressurizing for at least 2 hours, repeat the vacuum breakdown - vacuum drying process.) Leave as a vacuum for 1 hour after that, and make sure the vacuum gauge does not rise.

10. Indicates local procurement11. Outdoor unit12. BP unit
NoteThe shutoff valve must always be turned to “closed”. Otherwise the refrigerant in the outdoor unit will pour out.
• The names of parts needed to operate the shutoff valve are shown in the figure below. The unit is shipped from the factory with the shutoff valve turned to the “closed” position.
• Since the side boards may be deformed if only a torque wrench is used when loosening or tightening flare nuts, always lock the shutoff valve with a wrench and then use a torque wrench.
• In cases where the unit is run in heating mode when the outside temperature is low or in other situations where the operating pres-sure might drop, seal the gas-side flare nut on the shutoff valve with silicon sealant or the like to prevent it from freezing.
Shutoff valve operation procedureHave a hex wrench ready (size: 4 mm and 6 mm).
Opening the valve
1. Place the hex wrench on the valve bar and turn counter-clock-wise.
2. Stop when the valve bar no longer turns. It is now open.
Close the valve
1. Place the hex wrench on the valve bar and turn clockwise.2. Stop when the valve bar no longer turns. It is now closed.
• A seal is attached to the point indicated by the arrow.Take care not to damage it.
• Be sure to tighten the valve lid securely after operating the valves.
• Use a push-rod-provided charging hose for operation.• Be sure to tighten the valve lid securely after operation.

9. POST-WORK CHECKSPerform the following checks after work is complete.(1) Drain pipe connection, removal of transport clasp →
See “5. PRECAUTIONS ON INSTALLATION”. (2) Incorrect power supply wiring, loose screws →
See “6-3 How to connect the power supply wiring”.(3) Incorrect interunit wiring, loose screws →
See “6-4 Interunit wiring connection procedure”.(4) Incorrect refrigerant piping connections →
See “7. PRECAUTIONS ON REFRIGERANT PIPING”.(5) Piping sizes, use of insulation →
See : “7-2 Selecting piping material”.“7-6 Heat insulation of piping”.
(6) Shutoff valve check →Make sure both the liquid-side and gas-side shutoff valves are open.
(7) Record of Amount of Refrigerant Added →Record it on “Record of Amount of Refrigerant Added” on the “Service Precautions” plate.
(8) Measuring the insulation of the main power circuit →• Use a 500V mega-tester. • Do not use the mega-tester for weak currents other than 220-
240V. (Interunit wiring)
Caution
To the pipe-layerAfter completing installation, be sure to open the valve.(Operating the unit with the valve shut will break the compressor.)
10. TEST RUNThis unit is equipped with a crank case heater to ensure smooth startup. Be sure to turn the power on at least 6 hours before operation in order to have power running to the crank case heater.
Warning
When leaving the unit with the power on, be sure to switch with another person doing the installation or close the front panel.
Precautions before turning the power on• Using insulating sheets, tape electric parts as described in the
“Service Precautions” plate on the back of the front panel.• All indoor units connected to the outdoor unit operate automati-
cally. Complete work on the indoor units in order to ensure maximum safety.
10-1 Power On–Check Operation• Make sure to perform the check operation after installation.
(If the air conditioner is operated using the indoor remote control-ler without performing the check operation, the malfunction code “U3” is displayed in the indoor remote controller, and normal oper-ation is disabled.)
• When making settings on the outdoor unit PC board (A2P) after turning the power on, do not touch anything other than the push-button switches and dip switches. (See the “Service Precautions” plate for the locations of the push-button switches (BS1-5) and dip switches (D1-1, 2) on the PC board (A2P).)
Tank with siphon pipe Other tanks
There is a siphon pipe inside, so the cylinder need not be upside-down to fill with liquid.(Stand the cylinder upright when filling.)
Stand the tank upside down and charge.
1. Calculate the amount of refrigerant to add as described in “Calculating the amount of refrigerant to add” in “7. PRECAUTIONS ON REFRIGERANT PIPING”.
2. After the vacuum drying is finished, open valve A and charge the calculated amount of refrigerant through the service port for the liquid-side shutoff valve.
3. Close valve A after charging is complete.Note: If all the refrigerant to be added cannot be charged using the above procedure, right-hand the procedure
below and re-charge the refrigerant.
If all the refrigerant could not be addedAdd refrigerant using the following procedure. See the “Service Precautions” plate attached to the control box lid on the outdoor unit for details on the settings for adding refrigerant.[Procedure]1.

• During the operation, monitor the outdoor unit operation status and check for any incorrect wiring.
<Precautions During Check Operation>• If operation is performed within 12 minutes of BP units and
outdoor units being turned on, H2P will light up, and the compressor will not run.Only perform operation after checking that the LED display is as shown in “10-1 Power On–Check Operation” 2. table.
• In order to ensure uniform refrigerant distribution, it may take up to around 10 minutes for the compressor to start up after the unit begins running. This is not a malfunction.
• Each indoor unit cannot be checked individually for problems.After this operation is complete, run the unit normally using the remote controller.
• The check run cannot be performed in recovery or other modes.• If the outlet pipe thermistor (R2T), the intake pipe thermistor
(R3T), and the pressure sensors (S1NPH and S1NPL) are removed before operation, the compressor might burn out, so avoid this under all circumstances.
10-2 Temperature control operation checklist
• After check operation is complete, checking the temperature con-trol using normal operation.(Heating is not possible if the outdoor temperature is 24˚C or higher. See the included operation manual.)(1) Make sure the indoor and outdoor units are operating nor-
mally.(If liquid compression by the compressor or other abnormal noises can be heard, stop the unit immediately, heat the crank case for a sufficient amount of time, and try again.)
(2) Run each indoor unit one at a time and make sure the corre-sponding outdoor unit is also running.
(3) Check to see if cold (or hot) air is coming out of the indoor unit.
(4) Press the fan direction and fan strength buttons on the indoor unit to see if they operate properly.
<Precautions during temperature control checks>• For around 5 minutes after the compressor stops, the compressor
will not run even if the “operate/stop” button on the remote control-ler is pressed.
• When the system operation is stopped by the remote controller, the outdoor units may continue operating for further 1 minutes at maximum.
• Malfunction code “U3” is displayed if check operation is not per-formed using the test run button the first time after installation. Perform the check operation in accordance with “10-1 Power On–Check Operation”.

11. CAUTION FOR REFRIGERANT LEAKS(Points to note in connection with refrigerant leaks)
Introduction
The installer and system specialist shall secure safety against leakage according to local regulations or standards. The follow-ing standards may be applicable if local regulations are not available.
This system uses R410A as refrigerant. R410A itself is an entirely safe non-toxic, non-combustible refrigerant. Nevertheless care must be taken to ensure that air conditioning facilities are installed in a room which is sufficiently large. This assures that the maximum con-centration level of refrigerant gas is not exceeded, in the unlikely event of major leak in the system and this in accordance to the local applicable regulations and standards.
Maximum concentration level
The maximum charge of refrigerant and the calculation of the maxi-mum concentration of refrigerant is directly related to the humanly occupied space in to which it could leak.
The unit of measurement of the concentration is kg/m3 ( the weight in
kg of the refrigerant gas in 1m3 volume of the occupied space).
Compliance to the local applicable regulations and standards for the maximum allowable concentration level is required.
In Australia the maximum allowed concentration level of refrigerant to a humanly space is limited to 0.44 kg/m
3 for R410A.
Pay a special attention to the place, such as a basement, etc. where refrigerant can stay, since refrigerant is heavier than air.
Procedure for checking maximum concentration
Check the maximum concentration level in accordance with steps 1 to 4 below and take whatever action is necessary to comply.
1. Calculate the amount of refrigerant (kg) charged to each systemseparately.
Note• Where a single refrigerant facility is divided into 2 entirely inde-
pendent refrigerant systems then use the amount of refrigerantwith which each separate system is charged.
2. Calculate the smallest room volume (m3 )
Incase like the following, calculate the volume of (A), (B) as a sin-gle room or as the smallest room.

Cautions on inspecting the control box for service
Warning Caution: Electric shock
1. Before starting the service inspection, confirm using the tester that the power is shut down in the power terminal block (X1M).
2. Avoid contact with the hot area.Some portions are extremely hot in electric parts and the inside.
3. Avoid contact with the charged area. Never touch the charged area before confirming that the residual voltage is 50 V or less. 1 Shut down the power, and then leave the control box for 10 minutes. 2 Make sure to touch the earth terminal to release the static electricity from
your body (to prevent failure of the PC board). 3 Measure the residual voltage in the specified measurement position using
the tester while paying attention not to touch the charged area. 4 Immediately after measuring the residual voltage, disconnect the connectors of
the outdoor unit fan motor. (If the fan rotates by strong wind blowing against it, the capacitor will be charged, causes the danger of electric shock.)
After finishing the inspection, re-connect the connectors of the outdoor unit fan motor.

1. About brazing pipes on site 1) Before brazing, remove the heat insulation.
2) Remove the blue-colored tape, and throw it out.
3) Wrap the pipes to be brazed with sufficient wet cloths so that brazing does not affect the unit.
4) After brazing, use wet cloths or spray mist to sufficiently cool off all pipes.
5) When brazing, be careful that the flame of the torch does not come in contact with the unit.(Since the inside of the unit is made of plastic, it may become deformed or melt, destroying its heat-insulation performance.)
2. Insulation of pipes 1) Attach heat insulation to each pipe.
2) When attaching insulation to the pipes, use one-sided adhesive tape or similar materials to thoroughly prevent air from entering the heat insulation.
3) Eliminate any gaps in the heat insulation.
3. Unconnected pipes 1) For pipes not yet connected to a room, pinch the end of the pipe and
braze them.
2) When brazing this area too, wrap the pipes with sufficient wet cloths to protect the unit.
3) After brazing this area too, cool the pipes sufficiently.
4) Attach heat insulation, and use one-sided adhesive tape to thoroughly prevent air from entering the heat insulation.

Safety Precautions• Read these Safety Precautions carefully to ensure correct installation.• This manual classifies the precautions into WARNING and CAUTION. Be sure to follow all the precautions below: they are all important for ensuring safety.
WARNING
CAUTION
WARNING
CAUTION
Failure to follow any of WARNING is likely to result in such grave consequences as death or serious injury.
Failure to follow any of CAUTION may result in grave consequences in some cases.
• The following safety symbols are used throughout this manual:
Be sure to observe this instruction. Be sure to establish an earth connection. Never attempt.
• After completing installation, test the unit to check for installation errors. Give the user adequate instructions concerning the use and cleaning of the unit according to the Operation Manual.
• Installation should be left to the dealer or another professional. Improper installation may cause water leakage, electrical shock, or fire.
• Install the air conditioner according to the instructions given in this manual. Incomplete installation may cause water leakage, electrical shock, or fire.
• Be sure to use the supplied or specified installation parts. Use of other parts may cause the unit to come to lose, water leakage, electrical shock, or fire.
• Install the air conditioner on a solid base that can support the weight of the unit. An inadequate base or incomplete installation may cause injury in the event the unit falls off the base.
• Electrical work should be carried out in accordance with the installation manual and the national electrical wiring rules or code of practice. Insufficient capacity or incomplete electrical work may cause electrical shock or fire.
• Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance.
• The installation height from the floor must be over 1.8m.
• Use the specified types of wires for electrical connections between the indoor and outdoor units. When installing wiring for the outdoor unit, after cutting the wires for each connection point, a length of 3mm or longer is required. Firmly clamp the interconnecting wires so their terminals receive no external stresses. Incomplete connections or clamping may cause terminal overheating or fire.
• For wiring, use a cable length enough to cover the entire distance with no connection. Do not use an extension cord. Do not put other loads on the power supply, use a dedicated power circuit. (Failure to do so may cause abnormal heat, electric shock or fire.) The power supply wire class for the receptacle for the outdoor unit must be polychlorinated vinyl insulation or higher. (IEC60057: No. 245 wire)
• After all installation is complete, check to make sure that no refrigerant is leaking out. (The refrigerant produces a toxic gas if exposed to flames.)
• Do not install the air conditioner in a place where there is danger of exposure to inflammable gas leakage. If the gas leaks and builds up around the unit, it may catch fire.
• Establish drain piping according to the instructions of this manual. Inadequate piping may cause flooding.
• Tighten the flare nut according to the specified method such as with a torque wrench. If the flare nut is tightened too hard, the flare nut may crack after a long time and cause refrigerant leakage.
• Note for installing the outdoor unit. (For heat pump model only.) In cold area where the outside air temperature keep below or around freezing-point for a few days, the outdoor unit’s drain may freeze. If so, it is recommended to install an electric heater in order to protect drain from freezing. It is recommended that you contact the after-sales service organization.
• After connecting interconnecting and supply wiring be sure to shape the cables so that they do not put undue force on the electrical covers or panels. Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, or fire. When electrical appliances are connected in Y formation, if the power supply is damaged in some way, to avoid danger the power supply must be replaced by the maker or by someone with an equivalent certification.
• When installing or relocating the system, be sure to keep the refrigerant circuit free from substances other than the specified refrigerant (R410A), such as air. (Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise or rupture, resulting in injury.)
• If any refrigerant has leaked out during the installation work, ventilate the room. (The refrigerant produces a toxic gas if exposed to flames.)
• Be sure to establish an earth. Do not earth the unit to a utility pipe, arrester, or telephone earth. Incomplete earth may cause electrical shock, or fire. A high surge current from lightning or other sources may cause damage to the air conditioner.
• Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in electric shocks, or fire.
• During pump-down, stop the compressor before removing the refrigerant piping. If the compressor is still running and the shut-off valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormal pressure in the freezer cycle which will lead to breakage and even injury.
• During installation, attach the refrigerant piping securely before running the compressor. If the compressor is not attached and the shut-off valve is open during pump-down, air will be sucked in when the compressor is run, causing abnormal pressure in the freezer cycle which will lead to breakage and even injury.

1. Flaring the pipe end.1) Cut the pipe end with a pipe cutter.2) Remove burrs with the cut surface facing downward
so that the chips do not enter the pipe.3) Put the flare nut on the pipe.4) Flare the pipe.5) Check that the flaring is properly made.
1) Do not use mineral oil on flared part.2) Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.3) Never use piping which has been used for previous installations. Only use parts which are delivered with the unit.4) Do never install a drier to this R410A unit in order to guarantee it’s lifetime.5) The drying material may dissolve and damage the system.6) Incomplete flaring may cause refrigerant gas leakage.

Refrigerant Piping Work
2. Refrigerant piping.
2-1. Caution on piping handling.1) Protect the open end of the pipe against dust and moisture.2) All pipe bends should be as gentle as possible. Use a pipe
bender for bending.
2-2. Selection of copper and heat insulation materials.• When using commercial copper pipes and fittings, observe the following:1) Insulation material: Polyethylene foam
Heat transfer rate: 0.041 to 0.052W/mK (0.035 to 0.045kcal/(mh •˚C))Refrigerant gas pipe’s surface temperature reaches 110˚C max.Choose heat insulation materials that will withstand this temperature.
2) Be sure to insulate both the gas and liquid piping and to provide insulation dimensions as below.
1. Flaring the pipe end.1) Cut the pipe end with a pipe cutter.2) Remove burrs with the cut surface facing
downward so that the chips do not enter the pipe.
3) Put the flare nut on the pipe.4) Flare the pipe.5) Check that the flaring is properly made.
1) Do not use mineral oil on flared part.2) Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.3) Never use piping which has been used for previous installations. Only use parts which are delivered with the unit.4) Do never install a drier to this R410A unit in order to guarantee it’s lifetime.5) The drying material may dissolve and damage the system.6) Incomplete flaring may cause refrigerant gas leakage.

CHOOSING A SITE• Before choosing the installation site, obtain user approval.
Caution• When moving the unit during or after unpacking, make sure to lift it by holding its lifting lugs. Do not exert any pressure on
other parts, especially the refrigerant piping, drain piping and flange parts.Wear protective gears (gloves and so on) when installing the unit.
• If you think the humidity inside the ceiling might exceed 30°C and RH80%, reinforce the insulation on the unit body.Use glass wool or polyethylene foam as insulation so that the thickness is more than 10mm and fits inside the ceiling opening.
• Optimum air distribution is ensured.• The air passage is not blocked.• Condensate can drain properly.• The ceiling is strong enough to bear the weight of the indoor unit.• A false ceiling does not seem to be at an incline.• Sufficient clearance for maintenance and servicing is ensured.• Piping between the indoor and outdoor units is within the allowable limits.
(Refer to the installation manual for the outdoor unit.)• The indoor unit, outdoor unit, power supply wiring and transmission wiring is at least 1
meter away from televisions and radios. This prevents image interference and noise in electrical appliances. (Noise may be generated depending on the conditions under which the electric wave is generated, even if a one-meter allowance is maintained.)
Use suspension bolts to install the unit. Check whether or not the ceiling is strong enough to support the weight of the unit. If there is a risk that the ceiling is not strong enough, reinforce the ceiling before installing the unit.(Installation pitch is marked on the carton box for installation. Refer to it to check for points requiring reinforcing.) Select the *H dimension such that a downward slope of at least 1/100 is ensured as indicated in “DRAIN PIPING WORK”.• The installation pitch is listed on the packing material, and should be
checked when deciding whether to reinforce the location or not.

CHOOSING A SITESelect the signal receiver mounting location according to the following conditions:• Install the signal receiver, which has a built-in temperature sensor, near the intake vent
where there is convection of air and it can get an accurate reading of the room’s temperature. If the intake vent is in another room or the unit cannot be installed near the intake vent for any other reason, install it 1.5m above the floor on a wall where there is convection.
• In order to get an accurate reading of the room’s temperature, install the signal receiver in a location where it is not exposed directly to cold or hot air from the air discharge grille or to direct sunlight.
• Since the receiver has a built-in light receptor to receive signals from the wireless remote controller, do not mount it in a location where the signal may be blocked by a curtain, etc.
CautionIf the signal receiver is not installed in a location where there is convection of air, it may be unable to get an accurate reading of the room’s temperature.
• Turn on all the fluorescent lamps in the room, if any, and find the site where remote controller signals are properly receivedby the indoor unit (within 4 metres).
• For outdoor unit installation, see the installation manual supplied with the outdoor unit.

REFRIGERANT PIPING WORK 3) After the work is finished, make sure to check that there is no
gas leak.
4) After checking for gas leaks, be sure to insulate the pipe connections.• Insulate using the insulation for fitting included with the liquid and gas pipes. Besides, make sure the insulation for fitting
on the liquid and gas piping has its seams facing up.(Tighten both edges with clamp.)
• For the gas piping, wrap the medium sealing pad over the insulation for fitting (flare nut part).
CautionBe sure to insulate any field piping all the way to the piping connection inside the unit. Any exposed piping may cause condensation or burns if touched.
Cautions on Pipe Handling• Protect the open end of the pipe against dust and moisture.
(Tighten both edges with clamp.)• All pipe bends should be as gentle as possible. Use a pipe bender for
bending.(Bending radius should be 30 to 40 mm or larger.)
Selection of Copper and Heat Insulation materialsWhen using commercial copper pipes and fittings, observe the following:• Insulation material: Polyethylene foam
Heat transfer rate: 0.041 to 0.052W/mK (0.035 to 0.045 kcal/mh°C)Refrigerant gas pipe’s surface temperature reaches 110°C max.Choose heat insulation materials that will withstand this temperature.
• Be sure to insulate both the gas and liquid piping and to provide insulation dimensions as below.
Also, when subject to high humidity, heat insulation of the refrigerant piping (the unit piping and branch piping) must be further reinforced.Reinforce the insulation when installing the unit near bathrooms, kitchens, and other similar locations.Refer to the following:
• 30°C, more than 75% RH: 20 mm Min. in thicknessIf the insulation is not sufficient, condensation may form on the surface of the insulation.
• Use separate thermal insulation pipes for gas and liquid refrigerant pipes.

DRAIN PIPING WORKCaution
Make sure all water is out before making the duct connection.
Install the drain piping.• Make sure the drain works properly.• The diameter of the drain pipe should be greater than or equal to the
diameter of the connecting pipe (vinyl tube; pipe size: 20 mm; outer dimension: 26 mm).
• Keep the drain pipe short and sloping downwards at a gradient of at least 1/100 to prevent air pockets from forming.
CautionWater accumulating in the drain piping can cause the drain to clog.
• To keep the drain tube from sagging, space hanging wires every 1 to 1.5 m.• Use the drain hose and the metal clamp. Insert the drain hose fully into the drain socket and firmly tighten the metal clamp with
the upper part of the tape on the hose end. Tighten the metal clamp until the screw head is less than 4 mm from the hose.• The two areas below should be insulated because condensation may form there causing water to leak.
• Drain piping passing indoors• Drain sockets
Referring the figure below, insulate the metal clamp and drain hose using the included large sealing pad.
⟨ PRECAUTIONS ⟩Drain piping connections• Do not connect the drain piping directly to sewage pipes that smell of ammonia. The ammonia in the sewage might enter the
indoor unit through the drain pipes and corrode the heat exchanger.• Do not twist or bend the drain hose, so that excessive force is not applied to it.
(This type of treatment may cause leaking.)
After piping work is finished, check drainage flows smoothly.• Gradually insert approximately 1,000 cc of water into the drain pan to
check drainage in the manner described below.• Gradually pour approximately 1,000 cc of water from the outlet
hole into the drain pan to check drainage.• Check the drainage.

DRAIN PIPING WORKCaution
Make sure all water is out before making the duct connection.
Install the drain piping.• Make sure the drain works properly.• The diameter of the drain pipe should be greater than or equal to the
diameter of the connecting pipe (vinyl tube; pipe size: 20mm; outer dimension: 26mm).
• Keep the drain pipe short and sloping downwards at a gradient of at least 1/100 to prevent air pockets from forming.
CautionWater accumulating in the drain piping can cause the drain to clog.
• To keep the drain tube from sagging, space hanging wires every 1 to 1.5m.• Use the drain hose and the metal clamp. Insert the drain hose fully into the drain socket and firmly tighten the metal clamp with
the upper part of the tape on the hose end. Tighten the metal clamp until the screw head is less than 4mm from the hose.• The two areas below should be insulated because condensation may form there causing water to leak.
• Drain piping passing indoors• Drain sockets
Referring the figure below, insulate the metal clamp and drain hose using the included large sealing pad.
PRECAUTIONS Drain piping connections• Do not connect the drain piping directly to sewage pipes that smell of ammonia. The ammonia in the sewage might enter the
indoor unit through the drain pipes and corrode the heat exchanger.• Do not twist or bend the drain hose, so that excessive force is not applied to it.
(This type of treatment may cause leaking.)
After piping work is finished, check drainage flows smoothly.• Gradually insert approximately 1L of water into the drain pan to check
drainage in the manner described below.• Gradually pour approximately 1L of water from the outlet hole into
the drain pan to check drainage.• Check the drainage.

6. REFRIGERANT PIPING WORK<For refrigerant piping of outdoor units, see the installation manual attached to the outdoor unit.><Execute heat insulation work completely on both sides of the gas piping and the liquid piping. Otherwise, a water leakage can result sometimes.>(When using a heat pump, the temperature of the gas piping can reach up to approximately 120˚C, so use insulation which is sufficiently resistant.)<Also, in cases where the temperature and humidity of the refrigerant piping sections might exceed 30˚C or RH80%, reinforce the refrigerant insulation. (20 mm or thicker) Condensation may form on the surface of the insulating material.><Before refrigerant piping work, check which type of refrigerant is used. Proper operation is not pos-sible if the types of refrigerant are not the same.>
CAUTION• Use a pipe cutter and flare suitable for the type of refrigerant.• Apply ester oil or ether oil around the flare portions before connectiong.• To prevent dust, moisture or other foreign matter from infiltrating the tube, either pinch the end
or cover it with tape.• Do not allow anything other than the designated refrigerant to get mixed into the refrigerant
circuit, such as air, etc. If any refrigerant gas leaks while working on the unit, ventilate the room thoroughly right away.
• The outdoor unit is charged with refrigerant. • Be sure to use both a spanner and torque wrench together, as
shown in the drawing, when connecting or disconnecting pipes to/from the unit. (Refer to Fig. 13)
• Refer to “ Table 3” for the dimensions of flare nut spaces.• When connecting the flare nut, coat the flare section (both inside and
outside) with ester oil or ether oil, rotate three or four times first, then screw in. (Refer to Fig. 14)
CAUTION
Over-tightening may damage the flare and cause a refrigerant leakage.
NOTE• Use the flare nut included with the unit main body.Table 3
• Refer to “Table 3” to determine the proper tightening torque.

Not recommendable but in case of emergency You must use a torque wrench but if you are obliged to install the unit without a torque wrench, you may fol-low the installation method mentioned below.
After the work is finished, make sure to check that there is no gas leak.
When you keep on tightening the flare nut with a spanner, there is a point where the tightening torque sud-denly increases. From that position, further tighten the flare nut the angle shown below:
CAUTIONCAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT PIPING“Do not use flux when brazing refrigerant piping. Therefore, use the phosphor copper brazing filler metal (BCuP-2: JIS Z 3264/B-Cu93P-710/795: ISO 3677) which does not require flux.”(Flux has extremely harmful influence on refrigerant piping systems. For instance, if the chlorine based flux is used, it will cause pipe corrosion or, in particular, if the flux contains fluorine, it will damage the refrigerant oil.)
• Before brazing local refrigerant piping, nitrogen gas shall be blown through the piping to expel air from the piping.If your brazing is done without nitrogen gas blowing, a large amount of oxide film develops inside the pip-ing, and could cause system malfunction.
• When brazing the refrigerant piping, only begin brazing after having carried out nitrogen substitution or while inserting nitrogen into the refrigerant piping. Once this is done, connect the indoor unit with a flared or a flanged connection.
• Nitrogen should be set to 0.02 MPa (0.2 kg/cm2) with a pressure-reducing valve if brazing while inserting nitrogen into the piping. (Refer to Fig.15)
• Make absolutely sure to execute heat insulation works on the pipe-connecting section after checking gas leakage by thoroughly studying the following figure and using the attached heat insulating materials for fit-ting (8) and (9). (Fasten both ends with the clamps (4).)

Precautions to be taken for power supply wiringUse a round crimp-style terminal for connection to the power supply terminal block. In case it cannot be used due to unavoidable reasons, be sure to observe the following instructions. Be sure to peel off the sheath of wiring between units more than 80 mm.(Refer to Fig. 30)• In wiring, make certain that prescribed wires are used, carry out complete connections, and fix the wires
so that external forces are not applied to the terminals.
When none are available, follow the instructions below.• Do not connect wires of different gauge to the same power supply terminal.
(Looseness in the connection may cause overheating.)
CAUTION• When clamping wiring, use the included clamping material to prevent outside pressure being exerted on the
wiring connections and clamp firmly. When doing the wiring, make sure the wiring is neat and does not cause the control box lid to stick up, then close the cover firmly.
• When attaching the control box lid, make sure you do not pinch any wires.• After all the wiring connections are done, fill in any gaps in the through holes with putty or insulation (pro-
cured locally) to prevent small animals and insects from entering the unit from outside. (If any do get in, they could cause short circuits in the control box.)
• Outside the machine, separate the weak wiring (remote controller cord) and strong wiring (interunit, ground, and other power wiring) at least 50 mm so that they do not pass through the same place together. Proximity may cause electrical interference, malfunctions, and breakage.

6. REFRIGERANT PIPING WORK<For refrigerant piping of outdoor unit and BP unit, see the installation manuals attached to the out-door unit and BP unit.><Execute heat insulation work completely on both sides of the gas piping and the liquid piping. Otherwise, awater leakage can result sometimes.>(When using a heat pump, the temperature of the gas piping can reach up to approximately 120°C, so useinsulation which is sufficiently resistant.)<Also, in cases where the temperature and humidity of the refrigerant piping sections might exceed 30°C orRH80%, reinforce the refrigerant insulation. (20 mm or thicker) Condensate may form on the surface of theinsulating material.><Be sure to check the type of refrigerant to be used before doing any work. (Using an incorrect refrigerant will prevent normal operation of the unit.)>
CAUTION• Use a pipe cutter and flare suitable for the type of refrigerant.• Apply ester oil or ether oil around the flare section before connecting.• To prevent dust, moisture or other foreign matter from infiltrating the tube, either pinch the end or cover it
with tape.• Do not allow anything other than the designated refrigerant to get mixed into the refrigerant circuit, such
as air, etc. If any refrigerant gas leaks while working on the unit, ventilate the room thoroughly right away.
• Be sure to use both a spanner and torque wrench together, as shown in the drawing, when connecting or disconnecting pipes to/from the unit. (Refer to Fig. 17)
• Refer to “Table 3” for the dimensions of flare nut spaces.• When connecting the flare nut, apply ester oil or ether oil to the flare
section (both inside and outside), and spin 3-4 times before screw-ing in. (Refer to Fig. 18)
NOTE• Use the flare nut included with the unit main body.
Table 3
∗When refrigerant is R22, the dimensions in parentheses ( ) can also be used.
• Refer to “Table 3” to de termine the proper tightening torque.

Not recommendable but in case of emergency
You must use a torque wrench but if you are obliged to install the unit without a torque wrench, you mayfollow the installation method mentioned below
After the work is finished, make sure to check that there is no gas leak.
When you keep on tightening the flare nut with a spanner, there is a point where thetightening torque suddenly increases. From that position, further tighten the flare nut the angle shownbelow:
• Make absolutely sure to execute heat insulation works on the pipe-connecting section after checking gas leakage by thoroughly studying the following figure and using the attached heat insulating materials for fitting (8) and (9). (Fasten both ends with the clamps (4).) (Refer to Fig. 19)
• Wrap the sealing pad (11) only around the insulation for the joints on the gas piping side. (Refer to Fig. 19)
CAUTIONFor local insulation, be sure to insulate local piping all the way into the pipe connections inside the machine.Exposed piping may cause condensation or burns on contact.
CAUTIONCAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT PIPING“Do not use flux when brazing refrigerant piping. Therefore, use the phosphor copper brazing filler metal (BCuP-2: JIS Z 3264/B-Cu93P-710/795: ISO 3677) which does not require flux.”(Flux has extremely harmful influence on refrigerant piping systems. For instance, if the chlorine based flux is used, it will cause pipe corrosion or, in particular, if the flux contains fluorine, it will damage the refrig-erant oil.)
• Before brazing local refrigerant piping, nitrogen gas shall be blown through the piping to expel air from the piping.If you brazing is done without nitrogen gas blowing, a large amount of oxide film develops inside the piping, and could cause system malfunction.

• When brazing the refrigerant piping, only begin brazing after having carried out nitrogen substitution or while inserting nitrogen into the refrigerant piping. Once this is done, connect the indoor unit with a flared or a flanged connection.
• Nitrogen should be set to 0.02 Mpa (0.2 kg/cm2) with a pressure-reducing valve if brazing while inserting
nitrogen into the piping. (Refer to Fig. 20)
7. DRAIN PIPING WORK(1) Rig drain piping• As for drain work, perform piping in such a manner that water can be drained properly.
As for drain piping, the connection can be made from three different directions.• Employ a pipe with either the same diameter or with the diameter larger (excluding the raising section) than
that of the connecting pipe (PVC pipe, nominal diameter 25 mm, outside diameter 32 mm).• Keep the drain pipe short and sloping downwards at a gradient of at least 1/100 to prevent air pockets from
forming.• If the drain pipe cannot be sufficiently set on a slope, execute the drain raising piping.• To keep the drain pipe from sagging, space hanging wires every 1 to 1.5 m.
CAUTIONWater pooling in the drainage piping can cause the drain to clog.
• Use the attached drain hose (1) and Metal clamp (2).• Insert the drain hose into the drain socket up to the base, and tighten the Metal clamp securely within the
portion of a white tape of the hose-inserted tip. Tighten the Metal clamp until the screw head is less than 4 mm from the hose.

When you keep on tightening the flare nut with a spanner, there is a point where thetightening torque suddenly increases. From that position, further tighten the flare nut the angle shownbelow:
• Make absolutely sure to execute heat insulation works on the pipe-connecting section after checking gas leakage by thoroughly studying the following figure and using the attached heat insulating materials for fitting (4) and (5). (Fasten both ends with the clamps (9).) (Refer to Fig. 8)
• Wrap the sealing pad (7) only around the insulation for the joints on the gas piping side. (Refer to Fig. 8)
CAUTIONFor local insulation, be sure to insulate local piping all the way into the pipe connections inside the machine.Exposed piping may cause condensation or burns on contact.
CAUTIONCAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT PIPING“Do not use flux when brazing refrigerant piping. Therefore, use the phosphor copper brazing filler metal (BCuP-2: JIS Z 3264/B-Cu93P-710/795: ISO 3677) which does not require flux.”(Flux has extremely harmful influence on refrigerant piping systems. For instance, if the chlorine based flux is used, it will cause pipe corrosion or, in particular, if the flux contains fluorine, it will damage the refrig-erant oil.)
• Before brazing local refrigerant piping, nitrogen gas shall be blown through the piping to expel air from the piping.If you brazing is done without nitrogen gas blowing, a large amount of oxide film develops inside the piping, and could cause system malfunction.
• When brazing the refrigerant piping, only begin brazing after having carried out nitrogen substitution or while inserting nitrogen into the refrigerant piping. Once this is done, connect the indoor unit with a flared or a flanged connection.

• Nitrogen should be set to 0.02 Mpa (0.2 kg/cm2) with a pressure-reducing valve if brazing while inserting
nitrogen into the piping. (Refer to Fig. 9)
7. DRAIN PIPING WORK1. Rig drain piping (Refer to Fig. 10, Fig. 11)
• As for drain work, perform piping in such a manner that water can be drained properly.As for drain piping, the connection can be made from three different directions.
• Employ a pipe with either the same diameter or with the diameter larger (excluding the raising section) than that of the connecting pipe (PVC pipe, nominal diameter 25 mm, outside diameter 32 mm).
• Keep the drain pipe short and sloping downwards at a gradient of at least 1/100 to prevent air pockets from forming.
• If the drain pipe cannot be sufficiently set on a slope, execute the drain raising piping.• To keep the drain pipe from sagging, space hanging wires every 1 to 1.5 m.
CAUTIONWater pooling in the drainage piping can cause the drain to clog.
• Use the attached drain hose (3) and Metal clamp (1).• Insert the drain hose into the drain socket up to the base, and tighten the Metal clamp securely within
the portion of a white tape of the hose-inserted tip. Tighten the Metal clamp until the screw head is less than 4 mm from the hose.
• Wrap the attached sealing pad (6) over the Metal clamp and drain hose to insulate.• Make sure that heat insulation work is executed on the following 2 spots to prevent any possible water
leakage due to dew condensation.• Indoor drain pipe• Drain socket

Observe the notes mentioned below when wiring to the terminal block for wiring the units.
CAUTION• When clamping wiring, use the included clamping material to prevent outside pressure being exerted on
the wiring connections and clamp firmly. When doing the wiring, make sure the wiring is neat and does not cause the control box lid to stick up, then close the cover firmly.
• When attaching the control box lid, make sure you do not pinch any wires.• After all the wiring connections are done, fill in any gaps in the through holes with putty or insulation (pro-
cured locally) to prevent small animals and insects from entering the unit from outside. (If any do get in, they could cause short circuits in the control box.)
• Outside the machine, separate the weak wiring (remote controller cord) and strong wiring (interunit, ground, and other power wiring) at least 50 mm so that they do not pass through the same place together.Proximity may cause electrical interference, malfunctions, and breakage.
• Do not connect wires of different gauge to the same power supply terminal. (Looseness in the connection may cause overheating.) (Refer to Fig. 20)
• Observe the notes when wiring to the terminal block for wiring the units.(Use a round crimp-style terminal with insulation sleeve for connection to the terminal block for wiring the units. In case it cannot be used due to unavoidable reasons, connect wires of the same gauge to the both side as shown in Fig. 20.)
Follow the instructions below if the wiring gets very hot due to slack in the power wiring.• In wiring, make certain that prescribed wires are used, carry out complete connections, and fix the wires so
that outside forces are not applied to the terminals.• Use the correct screwdriver for tightening the terminal screws. If the blade of screwdriver is too small, the
head of the screw might be damaged, and the screw will not be properly tightened.• If the terminal screw are tightened too hard, screws might be damaged.• Refer to the table below for the tightening torque of the terminal screws.

REGARDING USESuper Multi Plus System air conditioner
POINTS THE CUSTOMER SHOULD BE AWARE OFCOMFORTAt startup• After the power is initially turned on, it will take approx. 10 minutes until startup. Usually the unit will start
in 3 minutes.
Heating operation (Not for a unit for cooling only)• The colder it is outside or the greater the number of indoor units, the longer the time required from the
start of operation until the emission of warm air (around 35°C). When the outside temperature is -5 to 2°C, the inside temperature is 5 to 10°C, and total indoor unit combination is 100% capacity, the first star-tup of all indoor units in the morning will take approximately 20 to 30 minutes.
• Oil return operation will be performed once every 8 hours to preserve the lubrication of oil to the com-pressor.Since operation is switched to cooling cycle during heating operation in order to return the oil, heating operation will not be possible for around 5 to 10 minutes.
• When the outside temperature is 28°C or higher, the unit will be set to the standby mode for protection.
OPERATING NOISEAt startup• During startup, in order to emit warm or cool air as quickly as possible, the sound of refrigerant flowing
will be heard for a short time (1 to 2 minutes) from the outdoor unit.
At shutdown• In order to ensure smooth startup the next time this unit is operated, the outdoor unit will continue to oper-
ate for around 1 minutes after shutdown. (The time of continued operation depends on the outside tem-perature, capacity of connected indoor units, and connection pipe length.)
Cooling at low outside temperatures• During cooling operation when the outside temperature is 20°C or less, the fan of the outdoor unit will
operate at low speed to preserve capacity and the outdoor unit valve will be opened depending on the pressure conditions, making it more likely that the sound of refrigerant flowing will be heard.
Defrost (Not for a unit for cooling only)• When the outside unit is performing defrosting operation, the fan of the indoor unit will stop temporarily,
and the slight sound of refrigerant flowing will be heard.
Excessive heating load (Not for a unit for cooling only)• During heating operation when the outside temperature is high (15 to 24°C), the fan of the outdoor unit
will be operated at low speed, making it more likely that the sound of refrigerant flowing will be heard from the outdoor unit.

• Do not stand or sit on the outdoor unit. Do not place any object on the unit to avoid injury, do not remove the fan guard.• Do not place anything under the indoor or outdoor unit that must be kept away from moisture. In certain conditions,
moisture in the air may condense and drip.• After a long use, check the unit stand and fittings for damage.• Do not touch the air inlet and aluminum fins of outdoor unit. It may cause injury.• The appliance is not intended for use by young children or infirm persons without supervision.• Young children should be supervised to ensure that they do not play with the appliance.
• To avoid oxygen deficiency, ventilate the room sufficiently if equipment with burner is used together with the air conditioner.
• Before cleaning, be sure to stop the operation, turn the breaker off or pull out the supply cord.• Do not connect the air conditioner to a power supply different from the one as specified. It may cause trou-
ble or fire.• Depending on the environment, an earth leakage breaker must be installed. Lack of an earth leakage breaker may
result in electric shocks.• Arrange the drain hose to ensure smooth drainage. Incomplete draining may cause wetting of the building, furniture
etc.• Do not place objects in direct proximity of the outdoor unit and do not let leaves and other debris accumulate around
the unit.Leaves are a hotbed for small animals which can enter the unit. Once in the unit, such animals can cause malfunc-tions, smoke or fire when making contact with electrical parts.
• Do not operate the air conditioner with wet hands.
• Do not wash the indoor unit with excessive water, only use a slightly wet cloth.• Do not place things such as vessels containing water or anything else on top of the unit. Water may pene-
trate into the unit and degrade electrical insulations, resulting in an electric shock.
To install the air conditioner in the following types of environments, consult the dealer.• Places with an oily ambient or where steam or soot occurs.• Salty environment such as coastal areas.• Places where sulfide gas occurs such as hot springs.• Places where snow may block the outdoor unit.
The drain from the outdoor unit must be discharged to a place of good drainage.
For installation, choose a place as described below.• A place solid enough to bear the weight of the unit which does not amplify the operation noise or vibration.• A place from where the air discharged from the outdoor unit or the operation noise will not annoy
your neighbours.
• For power supply, be sure to use a separate power circuit dedicated to the air conditioner.
• Relocating the air conditioner requires specialized knowledge and skills. Please consult the dealer if reloca-tion is necessary for moving or remodeling.

To set the batteries
1. Slide the front cover to take it off.
2. Set two dry batteries (AAA).
3. Set the front cover as before.
ATTENTIONAbout batteries• When replacing the batteries, use batteries of the same type, and replace the two old batteries
together.• When the system is not used for a long time, take the batteries out.• We recommend replacing once a year, although if the remote controller display begins to fade or if
reception deteriorates, please replace with new alkali batteries. Using manganese batteries reduces the lifespan.
• The attached batteries are provided for the initial use of the system.The usable period of the batteries may be short depending on the manufactured date of the air conditioner.

Preparation Before Operation
To operate the remote controller• To use the remote controller, aim the transmitter at
the indoor unit. If there is anything to block signals between the unit and the remote controller, such as a curtain, the unit will not operate.
• Do not drop the remote controller. Do not get it wet.• The maximum distance for communication is
about 7m.
To fix the remote controller holder on the wall
1. Choose a place from where the signals reach the unit.
2. Fix the holder to a wall, a pillar, or similar location with the screws procured locally.
3. Place the remote controller in the remote controller holder.
ATTENTIONAbout remote controller• Never expose the remote controller to direct sunlight.• Dust on the signal transmitter or receiver will reduce the sensitivity. Wipe off dust with soft cloth.• Signal communication may be disabled if an electronic-starter-type fluorescent lamp (such as
inverter-type lamps) is in the room. Consult the shop if that is the case.• If the remote controller signals happen to operate another appliance, move that appliance to
somewhere else, or consult the shop.

NOTETips for saving energy• Be careful not to cool the room too much.
Keeping the temperature setting at a moderate level helps save energy.• Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors increases the cooling effect.• Clogged air filters cause inefficient operation and waste energy. Clean them
once in about every two weeks.Please note• The air conditioner always consumes 15-35 watts of electricity even while it is not operating.• If you are not going to use the air conditioner for a long period, for example in spring or autumn, turn the breaker OFF.• Use the air conditioner in the following conditions.

Note for Multi System⟨⟨ What is a “Multi System”? ⟩⟩This system has one outdoor unit connected to multiple indoor units.
When the simultaneous operational capacity is exceededIf the simultaneous operational capacity is exceeded for outdoor unit capacity, the indoor unit enters Standby Mode, and the operation light flashed; this is not a malfunction.<Example>
When the units in rooms A, B, and C are being used, and the D is used, causing an overload:The room (from A to D) which is closest to the set temperature will go into standby mode. The room in standby mode will resume operation once operation in the other rooms is stopped.
NIGHT QUIET ModeNIGHT QUIET Mode requires initial programming during installation. Please consult your retailer or dealer for assistance.NIGHT QUIET Mode reduces the operation noise of the outdoor unit during the night time hours to prevent annoyance to neighbors.• The NIGHT QUIET Mode is activated when the temperature drops 5°C or more below the
highest temperature recorded that day. Therefore, when the temperature difference is less than 5°C, this function will not be activated.
• NIGHT QUIET Mode reduces slightly the cooling efficiency of the unit.
OUTDOOR UNIT QUIET Operation 1. With the Priority Room Setting present but inactive or not present.
When using the OUTDOOR UNIT QUIET operation feature with the Multi system, set all indoor units to OUTDOOR UNIT QUIET operation using their remote controllers.When clearing OUTDOOR UNIT QUIET operation, clear one of the operating indoor units using their remote controller.However OUTDOOR UNIT QUIET operation display remains on the remote controller for other rooms.We recommend you release all rooms using their remote controllers.

1.2.16 Troubleshooting
Trouble Shooting
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
These cases are not troubles.
Case ExplanationOperation does not start soon.• When ON/OFF button was
pressed soon after operation was stopped.
• When the mode was reselected.
• This is to protect the air conditioner.You should wait for about 3 minutes.
The outdoor unit emits water or steam.
In COOL or DRY mode• Moisture in the air condenses into water on the cool
surface of outdoor unit piping and drips.
Mists come out of the indoor unit.
This happens when the air in the room is cooled into mist by the cold air flow during cooling operation.
The indoor unit gives out odour. This happens when smells of the room, furniture, or cigarettes are absorbed into the unit and discharged with the air flow.(If this happens, we recommend you to have the indoor unit washed by a technician. Consult the service shop where you bought the air conditioner.)
The outdoor fan rotates while the air conditioner is not in operation.
After operation is stopped:• The outdoor fan continues rotating for another 60
seconds for system protection.While the air conditioner is not in operation:• When the outdoor temperature is very high, the out door
fan starts rotating for system protection.
The operation stopped suddenly.(OPERATION lamp is on.)
For system protection, the air conditioner may stop operating on a sudden large voltage fluctuation.It automatically resumes operation in about 3 minutes.

To gain full advantage of the air conditioner’s func-tions and to avoid malfunction due to mishandling, we recommend that you read this instruction man-ual carefully before use. This air conditioner is classified under “appliances not accessible to the general public”.• The precautions described herein are classi-
fied as WARNING and CAUTION. They both contain important information regarding safety. Be sure to observe all precautions without fail.
WARNING ...Failure to follow these instructions properly may result in personal injury or loss of life.
CAUTION ....Failure to observe these instruc-tions properly may result in prop-erty damage or personal injury, which may be serious depending on the circumstances.
• After reading, keep this manual in a conve-nient place so that you can refer to it when-ever necessary. If the equipment is transferred to a new user, be sure also to hand over the manual.
WARNINGBe aware that prolonged, direct exposure to cool or warm air from the air conditioner, or to air that is too cool or too warm can be harmful to your physical condition and health.When the air conditioner is malfunctioning (giving off a burning odour, etc.) turn off power to the unit and contact your local dealer.Continued operation under such circumstances may result in a failure, electric shocks or fire haz-ards.Consult your local dealer about installation work. Doing the work yourself may result in water leak-age, electric shocks or fire hazards.Consult your local dealer regarding modifi-cation, repair and maintenance of the air con-ditioner.Improper workmanship may result in water leak-age, electric shocks or fire hazards.Do not place objects, including rods, your fingers, etc., in the air inlet or outlet. Injury may result due to contact with the air con-ditioner’s highspeed fan blades.Beware of fire in case of refrigerant leakage.If the air conditioner is not operating correctly, i.e. not generating cool or warm air, refrigerant leakage could be the cause. Consult your dealer for assistance. The refrigerant within the air conditioner is safe and normally does not leak.
However, in the event of a leakage, contact with a naked burner, heater or cooker may result in generation of noxious gas. Do not longer use the air conditioner until a qual-ified service person confirms that the leakage has been repaired.Consult your local dealer regarding what to do in case of refrigerant leakage.When the air conditioner is to be installed in a small room, it is necessary to take proper mea-sures so that the amount of any leaked refriger-ant does not exceed the concentration limit in the event of a leakage. Otherwise, this may lead to an accident due to oxygen depletion.Contact professional personnel about attach-ment of accessories and be sure to use only accessories specified by the manufacturer.If a defect results from your own workmanship, it may result in water leaks, electric shock or fire. Consult your local dealer regarding reloca-tion and reinstallation of the air conditioner.Improper installation work may result in leakage, electric shocks or fire hazards.Be sure to use fuses with the correct ampere reading.Do not use improper fuses, copper or other wires as a substitute, as this may result in electric shock, fire, injury or damage to the unit.Be sure to earth the unit. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks or fire.A high surge current from lightning or other sources may cause damage to the air condi-tioner.Be sure to install an earth leakage breaker.Failure to install an earth leakage breaker may result in electric shocks or fire.Consult the dealer if the air conditioner sub-merges owing to a natural disaster, such as a flood or typhoon.Do not operate the air conditioner in that case, or otherwise a malfunction, electric shock, or fire may result.Do not start or stop operating the air condi-tioner with the power supply breaker turned ON or OFF.Otherwise, fire or water leakage may result. Fur-thermore, the fan will rotate abruptly if power fail-ure compensation is enabled, which may result in inlury.Do not use the product in the atmosphere contaminated with oil vapor, such as cooking oil or machine oil vapor.Oil vapor may cause crack damage, electric shocks, or fire.Do not use the product in places with exces-sive oily smoke, such as cooking rooms, or in places with flammable gas, corrosive gas, or metal dust.Using the product in such places may cause fire or product failures.
2. SAFETY PRECAUTIONS
Operation Manual 277
Operations EDSG18-936
3 English
Do not use flammable materials (e.g., hair-spray or insecticide) near the product.Do not clean the product with organic sol-vents such as paint thinner.The use of organic solvents may cause crack damage to the product, electric shocks, or fire.Be sure to use a dedicated power supply for the air conditioner.The use of any other power supply may cause heat generation, fire, or product failures.
CAUTIONDo not use the air conditioner for purposes other than those for which it is intended. Do not use the air conditioner for cooling preci-sion instruments, food, plants, animals or works of art as this may adversely affect the perfor-mance, quality and/or longevity of the object concerned.Do not remove the outdoor unit’s fan guard. The guard protects against the unit’s high speed fan, which may cause injury. Do not place objects that are susceptible to moisture directly beneath the indoor or out-door units.Under certain conditions, condensation on the main unit or refrigerant pipes, air filter dirt or drain blockage may cause dripping, resulting in fouling or failure of the object concerned.To avoid oxygen depletion, ensure that the room is adequately ventilated if equipment such as a burner is used together with the air conditioner.After prolonged use, check the unit stand and its mounts for damage.If left in a damaged condition, the unit may fall and cause injury.Do not place flammable sprays or operate spray containers near the unit as this may result in fire.Before cleaning, be sure to stop unit opera-tion, turn the breaker off or remove the power cord.Otherwise, an electric shock and injury may result.To avoid electric shocks, do not operate with wet hands. Do not place appliances that produce naked flames in places exposed to the air flow from the unit as this may impair combustion of the burner. Do not place heaters directly below the unit, as resulting heat can cause deformation. Do not allow a child to mount on the outdoor unit or avoid placing any object on it.Falling or tumbling may result in injury.Do not block air inlets nor outlets.Impaired air flow may result in insufficient perfor-mance or trouble.
Be sure that children, plants or animals are not exposed directly to airflow from the unit, as adverse effects may ensue. Do not wash the air conditioner with water, as this may result in electric shocks or fire.Do not install the air conditioner at any place where there is a danger of flammable gas leakage.In the event of a gas leakage, build-up of gas near the air conditioner may result in fire haz-ards.Do not put flammable containers, such as spray cans, within 1 m from the blow-off mouth.The containers may explode because the warm air output of the indoor or outdoor unit will affect them.Arrange the drain hose to ensure smooth drainage. Imperfect drainage may cause wetting. The appliance is not intended for use by unattended young children or infirm per-sons.Impairment of bodily functions and harm to health may result. Children should be supervised to ensure that they do not play with the unit or its remote controller.Accidental operation by a child may result in impairment of bodily functions and harm health.Do not let children play on or around the out-door unit.If they touch the unit carelessly, injury may be caused. Consult your dealer regarding cleaning the inside of the air conditioner. Improper cleaning may cause breakage of plas-tic parts, water leakage and other damage as well as electric shocks. To avoid injury, do not touch the air inlet or aluminium fins of the unit. Do not place objects in direct proximity of the outdoor unit and do not let leaves and other debris accumulate around the unit. Leaves are a hotbed for small animals which can enter the unit. Once in the unit, such animals can cause malfunctions, smoke or fire when making contact with electrical parts.Never touch the internal parts of the control-ler. Do not remove the front panel. Touching certain internal parts will cause electric shocks and damage to the unit. Please consult your dealer about checking and adjustment of internal parts. Do not leave the remote controller wherever there is a risk of wetting.If water gets into the remote controller there is a risk of electrical leakage and damage to elec-tronic components.

Tips for saving energy• Be careful not to cool (heat) the room too much.
Keeping the temperature setting at a moderate level helps save energy.
• Cover windows with a blind or a curtain.Blocking sunlight and air from outdoors increases the cooling (heating) effect.
Regarding places for installation• Is the air conditioner installed at a well-venti-
lated place where there are no obstacles around?
• Do not use the air conditioner in the following places.a. Filled with much mineral oil such as cutting oilb. Where there is much salt such as a beach areac. Where sulfured gas exists such as a hot-spring resort.d. Where there are considerable voltage fluctuations such as a factory or plante. Vehicles and vessels f. Where there is much spray of oil and vapor such as a cookery, etc.g. Where there are machines generating electromagnetic waves.h. Filled with acid and/or alkaline steam or vapor
• Is a snow protection measure taken? For details, consult your dealer.
Regarding wiring• All wiring must be performed by an autho-
rized electrician. To do wiring, ask your dealer. Never do it by yourself.• Make sure that a separate power supply circuit
is provided for this air conditioner and that all electrical work is carried out by qualified per-sonnel according to local laws and regulations.
Pay attention to running noises, too• Are the following places selected?
a. A place that can sufficiently withstand the weight of the air conditioner with less running noises and vibrations.b. A place where the hot wind discharged from the air outlet of outdoor unit and the running noises.
• Are you sure that there are no obstacles near the air outlet of the outdoor unit?Such obstacles may result in declined perfor-mance and increased running noises.
• If abnormal noises occur in use, stop the operation of the air conditioner, and then con-sult your dealer or our service station.
Regarding drainage of drain piping• Is the drain piping executed to perform com-
plete drainage?If proper drainage is not carried out from the out-door drain pipes during air-conditioning opera-tion, chances are that dust and dirt are clogged in the pipe. This may result in a water leakage from the indoor unit. Under such circumstances, stop the operation of the air conditioner, and then con sult your dealer or our service station.

Press ON/OFF buttonOPERATION lamp lights up or goes off and the sys-tem starts or stops OPERATION.
[EXPLANATION OF HEATING OPERATION]
(1) DEFROST OPERATION• As the frost on the coil of an outdoor unit
increase, heating effect decreases and the system goes into DEFROST OPERATION.
• The indoor unit fan stops and the remote con-troller display shows“ ”.
• After 6 to 8 minutes (maximum 10 minutes) of DEFROST OPERATION, the system returns to HEATING OPERATION.
(2) HOT START• In order to prevent cold air from blowing out of
an indoor unit at the start of heating operation, the indoor fan is automatically stopped. The display of the remote controller shows “ ” (DEFROST/HOT START).
(3) OPERATION START• For ordinary heating, it will take longer for the
room temperature to reach the set tempera-ture than with cooling. We therefore recom-mend starting the unit ahead of time using the timer operation.
Regarding outside air temperature and heating capacity• The heating capacity of the air conditioner
declines as the outside air temperature falls.In such a case, use the air conditioner in combi-nation with other heating systems.
• A warm air circulating system is employed, and therefore it takes some time until the entire room is warmed up after the start of operation.
• An indoor fan runs to discharge a gentle wind automatically until the temperature inside the air conditioner reaches a certain level. At this time, the remote controller displays“ ”. Leave it as it stands and wait for a while.
• When the warm air stays under the ceiling and your feet are cold, we recommend that you use a circulator (a fan to circulate the air inside the room). For details,consult your dealer.
For programming TEMPERATURE, FAN SPEED and AIR FLOW DIRECTION, follow the procedure shown below.
Press TEMPERATURE SETTING button and program the setting temperature.

The following symptoms do not indicate air condi-tioner malfunction
I. THE SYSTEM DOES NOT OPERATE• The system does not restart immediately
after the ON/OFF button is pressed.If the OPERATION lamp lights, the system is in normal condition.It does not restart immediately because a safety device operates to prevent overload of the sys-tem. After 3 minutes, the system will turn on again automatically.
• The system does not restart immediately when TEMPERATURE SETTING button is returned to the former position after pushing the button.If the OPERATION lamp lights, the system is in normal condition.
It does not restart immediately because a safety device operates to prevent overload of the sys-tem. After 3 minutes, the system will turn on again automatically.
• The system does not start when the display shows “ ” (UNDER CENTRALIZED CONTROL) and it flashes for few seconds after pressing an operation button.This is because the system is under centralized control. Flashes on the display indicates that the system cannot be controlled by the remote con-troller.
• The system does not start immediately after the power supply is turned on.Wait one minute until the micro computer is pre-pared for operation.
• The outdoor unit is stoppedThis is because the room temprerature has reached the set temprerature. The indoor unit switches to fan operation.
II. The display shows “ ” (UNDER CEN-TRALIZED CONTROL) and the unit operates in a mode different to what is shown on the remote controller display.When using a unit in a multi system, the opera-tion condition of that unit is controlled by a micro computer as described below, according to the operation condition of other indoor units con-nected to the system.
• If the operation mode does not match other indoor units that are already running, the indoor unit will assume the STANDBY state (the fan is stopped and the air flow flap is positioned hori-zontally).If HEATING mode is set together with COOLING, DRY or FAN mode, the above mentioned condi-tion will occur.
NOTE• Normally, the operation mode in the room where
the unit is first run is given priority, but the follow-ing situations are exceptions, so please keep this in mind.a. If the operation mode of the first room is FAN
Mode, then using Heating Mode in any room after this will give priority to heating. In this sit-uation, the air conditioner running in FAN Mode will go on standby.
b. With the Priority Room Setting active.Contact your Daikin dealer for the operation that corresponds to your system.
• If the total capacity of operating indoor units exceeds the limit, the indoor unit will assume the STANDBY state (FAN and AIR FLOW DIREC-TION will be left as set). (This only applies to cooling only type.)
• If another indoor unit commences a HEATING operation after this indoor unit is running in COOLING mode, this indoor unit may switch to DRY operation (fan on low, air flow flap set at hor-izontal).

III. The fan speed is different from the setting.• Pressing the fan speed control button does
not change the fan speed.When the room temperature reaches the set temperature in heating mode, the power supply from the outdoor unit is stopped and the indoor unit will operate on the low fan setting. (If using the multi system, the fan will alternate between off and low.)This is to prevent the cool air from being blown directly onto anyone in the room.
IV. AIR BLOW DIRECTION IS NOT AS SPECI-FIED.
• Actual air blow direction is not as shown on the remote contoller.
• Automatic swing setting does not work.Refer to “AIR FLOW DIRECTION ADJUST.”
V. WHITE MIST COMES OUT OF A UNIT• When humidity is high during cooling opera-
tion (In oily or dusty places)If the inside of an indoor unit is extremely con-taminated, the temperature distribution inside a room becomes uneven. It is necessary to clean the inside of the indoor unit. Ask your Daikin dealer for details on cleaning the unit. This oper-ation requires a qualified service person.
• When the system is changed over to HEATING OPERATION after DEFROST OPERATION.Moisture generated by DEFROST becomes steam and exists.
VI.NOISE OF AIR CONDITIONERS• A ringing sound after the unit is started.
This sound is generated by the temperature reg-ulator working. It will quiet down after about a minute.
• A continuous flow “Shuh” sound is heard when the systems is in COOLING or DEFROST OPERATION.This is the sound of refrigerant gas flowing through both indoor and outdoor units.
• A “Shuh” sound which is heard at the start or immediately after the stop of operation or which is heard at the start or immediately after the stop of DEFROST OPERATION. This is the noise of refrigerant caused by flow stop and flow change.
• A continuous flowing sound "Shah"or a trick-ling sound "Jyuru Jyuru"are heard when the system is in COOLING OPERATION or at a stop.The noise is heard when the drain pump is in operation.
• A “Pishi-pishi” squeaking sound is heard when the system is in operation or after the stop of operation.Expansion and contraction of plastic parts caused by temperature change makes this noise.
VII.DUST FROM THE UNITS• Dust may blow out from the unit after starting
operation from long resting time.Dust absorbed by the unit blows out.
VIII.THE UNITS GIVE OFF ODORSThe unit absorbs the smell of rooms, furniture, cigarettes, etc., and then emits them.
IX.THE LIQUID CRYSTAL OF THE REMOTE CONTROLLER SHOW “ ”
• It happens immediately after the main power supply switch is turned on.This shows that the remote controller is in nor-mal condition.This continues temporary.
X. THE ROOM TEMPERATURE DOES NOT DROP• The air conditioner is in program dry opera-
tion.The air conditioner in program dry operation does not drop the room temperature as much as possible. See page 5-6 “OPERATION PROCE-DURE”.

Clean the air filter and outside panels• After cleaning the air filter, make sure to attach it.
Turn on the main power supply switch• The display on the remote controller will be shown
when the power is turned on.• To protect the unit, turn on the main power switch
at least 6 hours before operation.
WHAT TO DO WHEN STOPPING THE SYS-TEM FOR A LONG PERIODTurn on FAN OPERATION for a half day and dry the unit.• Refer to “FAN OPERATION”.
Cut off the power supply.• When the main power switch is turned on, some
watts of electricity is being used even if the sys-tem is not operating.Turn off the main power supply switch for saving energy.
• The display on the remote controller will vanish when the main power switch is turned off.
Clean the air filter and the exterior.• Be sure to replace the air filter to its original place
after cleaning. Refer to “MAINTENANCE”.
The following symptoms do not indicate air condi-tioner malfunction
I. THE SYSTEM DOES NOT OPERATE• The system does not restart immediately after
the ON/OFF button is pressed.If the OPERATION lamp lights, the system is in normal condition.It does not restart immediately because a safety device operates to prevent overload of the sys-tem. After 3 minutes, the system will turn on again automatically.
• The system does not restart immediately when TEMPERATURE SETTING button is returned to the former position after pushing the button.If the OPERATION lamp lights, the system is in normal condition.It does not restart immediately because a safety device operates to prevent overload of the sys-tem. After 3 minutes, the system will turn on again automatically.
9. NOT MALFUNCTION OF THE AIR CONDITIONER
• The system does not start when the display shows “ ” (UNDER CENTRALIZED CONTROL) and it flashes for few seconds after pressing an operation button.This is because the system is under centralized con-trol. Flashes on the display indicates that the system cannot be controlled by the remote controller.
• The system does not start immediately after the power supply is turned on.Wait one minute until the micro computer is pre-pared for operation.
II. WHITE MIST COMES OUT OF A UNIT• When humidity is high during cooling opera-
tion (In oily or dusty places)If the inside of an indoor unit is extremely contam-inated, the temperature distribution inside a room becomes uneven. It is necessary to clean the inside of the indoor unit. Ask your Daikin dealer for details on cleaning the unit. This operation requires a qualified service person.
• When the system is changed over to HEATING OPERATION after DEFROST OPERATION.Moisture generated by DEFROST becomes steam and exists.
III.NOISE OF AIR CONDITIONERS• A ringing sound after the unit is started.
This sound is generated by the temperature reg-ulator working. It will quiet down after about a minute.
• A continuous flow “Shuh” sound is heard when the systems is in COOLING or DEFROST OPERATION.This is the sound of refrigerant gas flowing through both indoor and outdoor units.
• A “Shuh” sound which is heard at the start or immediately after the stop of operation or which is heard at the start or immediately after the stop of DEFROST OPERATION. This is the noise of refrigerant caused by flow stop and flow change.
• A continuous low “Shah” sound is heard when the system is in COOLING OPERATION or at a stop.The noise is heard when the drain pump is in operation.
• A “Pishi-pishi” squeaking sound is heard when the system is in operation or after the stop of operation.Expansion and contraction of plastic parts caused by temperature change makes this noise.
IV.DUST FROM THE UNITS• Dust may blow out from the unit after starting
operation from long resting time.Dust absorbed by the unit blows out.
Operation Manual 307
Operations EDSG18-936
V. THE UNITS GIVE OFF ODORSThe unit absorbs the smell of rooms, furniture, cigarettes, etc., and then emits them.
VI.THE LIQUID CRYSTAL OF THE REMOTE CON-TROLLER SHOW “ ”
• It happens immediately after the main power supply switch is turned on.This shows that the remote controller is in normal condition. This continues temporary.
I. If one of the following malfunctions occurs, take the measures shown below and contact your Daikin dealer.
The system must be repaired by a qualified service person.
WARNINGWhen the air conditioner is in abnormal con-ditions (smell of something burning, etc), turn off power, and contact your dealerContinued operation under such circumstances may result in a failure, electric shock, and fire.
• If a safety device such as a fuse, a breaker, or an earth leakage breaker frequently actuates, or ON/OFF switch does not properly work.Measure: Turn off the main power switch
• If water leaks from unit.Measure: Stop the operation.
• If the display “ ” (INSPECTION), “UNIT No.”, and the OPERATION lamp flash and the MAL-FUNCTION CODE appears.
Measure: Notify your Daikin dealer and inform him/her of the display.
10. TROUBLE SHOOTING
II. If the system does not properly operate except for the above mentioned case, and none of the above mentioned malfunctions is evident, investigate the system according to the following procedures.
1. If the system does not operate at all.• Check if there is a power failure.
Wait until power is restored. If power failure occurs during operation, the system automati-cally restarts immediately after the power sup-ply recovers.
• Check if the fuse has blown or breaker has worked. Change the fuse or set the breaker.
2. If the system stops operating after operating the system.• Check if the air inlet or outlet of outdoor or
indoor unit is blocked by obstacles.Remove the obstacle and make it well-venti-lated.
• Check if the air filter is clogged.Ask a qualified service person to clean the air filters (Refer to MAINTENANCE).
3. The system operates but it does not suffi-ciently cool or heat.• If the air inlet or outlet of the indoor or the out-
door unit is blocked with obstacles.Remove the obstacle and make it well-venti-lated.
• If the air filter is clogged.Ask a qualified service person to clean the air filters (Refer to MAINTENANCE).
• If the set temperature is not proper (Refer to ADJUSTMENT).
• If the FAN SPEED button is set to LOW SPEED (Refer to ADJUSTMENT).
• If the doors or the windows are open. Shut doors or windows to prevent wind from coming in.
• If direct sunlight enters the room (when cool-ing).Use curtains or blinds.
• When there are too many inhabitants in the room (when cooling).Cooling effect decreases if heat gain of the room is too large.
• If the heat source of the room is excessive (when cooling).Cooling effect decreases if heat gain of the room is too large.

• Timer Number Setting
Group control: select the unit in the individual
screen and set the timer number.
Batch control: set the timer numbers for all con-
nected units.
Zone control: set the timer numbers for all
zone-registered units.
Call up the zones which you wish
to set in the zone screen and set
the timer numbers.
• Since the timer number will be set to after-
press priority, the timer number in the last
screen set will be valid for the connected
units.
Example 1
Setting timer number 1 for unit 1-00 to “1” and
timer number 2 to “2” in the individual screen and
then setting timer number 1 to “3” and timer
number 2 to “4” in the batch screen causes the
timer numbers for all units to be set, so timer
number 1 for unit 1-00 will be “3” and timer num-
ber 2 will be “4”.
Example 2
To prevent leaving units on, timer number 1 is
set to “5” in the batch screen.
Setting timer number 1 in zone number 1 to “ ”
in the zone screen after that will change the
timer number for zone number 1, so the setting
to prevent leaving the units on will be lost for
zone number 1 only.
If a timer number is set incorrectly by accident,
redo the setting in the desired screen.
• What happens when the timer number on
time and off time are set to the same time
When the on time and off time are set to the
same time for the same timer number, operation
does not change.
When the on time and off time are set to the
same time for different timer numbers, the off
time is given priority.
When using timer operation, make sure the
times do not overlap when setting the program of
the schedule timer.

Setting master remote controller
(Fig. 15)You must set the master remote controller of the oper-
ation mode for one of the indoor units, if two or more
such indoor units with the remote controller are con-
nected with the outdoor unit where the operation
modes such as cool/heat operation and FAN operation
can be set by remote controller and central remote con-
troller.
1. Preparations
When you want to fix settings
• Check the particular group with the master
remote controller setting for the refrigerant
system you wish to reset. (See the below.)
• Call up the group without the display
“ ” (See page 16.)
Hold the OPERATION MODE SELECTOR
BUTTON down for about four seconds while
the above group is being called up.
The display “ ” flashes on the liq-
uid crystal display of the remote controller
for all the groups sharing the same outdoor
unit or BS unit.
When you turn on the power switch for the first
time, the display“ ” flashes.
2. Setting selection right
Pall up the desired group to set the master
remote controller, and press the OPERA-
TION MODE SELECTOR BUTTON. The master
remote controller is set for this group, and the
display “ ” goes out. The display
“ ” appears for the other groups.
Setting is finished now.
When switching operation
In case of operation switch
Call up the zone including the group with the
setting of master remote controller.
(Zone without the display “ ”)
Press the OPERATION MODE SELECTOR
BUTTON several times, and switch to the
desired operation mode.
Each time you press it, the display is switched
to “ ” “ ” “ ” and “ ” in sequence.
NOTE
• However, the displays “ ” “ ” and “VENTI-
LATION MODE” may appear in some zones,
depending on the type on indoor unit with which they
are connected.

[System Display]
1.Test run mode is necessary to display the system
display.
2. In order to turn on test run mode, select the appro-
priate air conditioner on the individual screen with
the cursor and then set its operation mode to either
cooling or heating. (The air conditioner does not
need to be running. It doesn’t matter if it is, though.)
3.Press the “inspection/test run” button twice to put it
into test run mode.
4.Pressing the “inspection/test run” button for four or
more seconds in test run mode will display the
“REF CIRCUIT.”

Call the unit whose system you wish to look up using
the arrow keys.
The “ ” on all groups in the same system as the
displayed group will light up.
Of those, the “ ” display in all groups which have
cooling/heating selection privilege will blink.
In this example, individual units 1-00, 1-03, 1-05,
1-06, 1-07, 2-02, and 2-03 are in the same system,
and 1-05 has the cooling/heating selection privi-
lege.
To look up other systems, call up all the units you wish
to look up using the arrow keys.
Pressing the inspection/test run button one more time
gets rid of the system display and ends it.
The unit will enter the individual screen automatically if
nothing is done for one minute in the system display
screen.
This function may not be available for all connected
outdoor units, in which case “REF CIRCUIT” will blink.
It will also not be correctly displayed if DIII-NET exten-
sion ADP is used.
Display of time to clean (Fig. 16)This central remote controller displays the time to clean
the air filter or air cleaner element for each group or any
given group by utilizing two types of signs. The display
“ ” tells the time to clean the air filter or the air
cleaner element of some group.
If a cleaning sign is displayedA filter or element in some group is ready to be
cleaned.
1. Press the ARROW KEY BUTTON, and
search the groups displaying “ ” or
“ ” (The group may be plural.)
2. Press the FILTER SIGN RESET BUT-
TON, and the display “ ” disap-
pears. (Including all the groups where the
air filter has been cleaned.)
NOTE
Be sure to check the display “ ” has
disappeared at this point. The appearance of the
above display is a sign that the air filter or air cleaner
element of some group still needs cleaning.
Clean or change the air filter or air cleaner
element.
For further details, see the operation manual
attached to each indoor unit. (Clean or change the
air filter or air cleaner element of all the groups dis-
playing “ ” or “ ”.)

OFF(Factory setting)
Open the Kit’s case and set the switches on the circuit board. (1) For Overseas / Japanese unit setting (SW3-3)
Room air conditioners, different methods are used for setting the temperature in automatic mode, so this switch needs to be set.
When using a central remote controller, the operating codes can be used to limit operation from wireless remote controllers.
: permitted; × : prohibited
The Operating / error signals can be read from the contact output (S5).Output specs
M1: Turn MR 1 ON when the air conditioner is running. M2: Turn MR 2 when a communication error has occurred between the KRP928B2S and
the air conditioner, or MR 1 is ON and the unit has stopped after an error.MR 2 is not turned ON during a warning.
(2) Group number settings (SW1 and SW2-1 to SW2-3)Set these when using the central controller. (Set to the side.) Do not set more than one unit to the same number.
However, these settings do not need to be made when using the schedule timer independently. (The settings are needed when used in conjunction with another DCS Series central controller.) In this case, the schedule timer performs an auto address after the power is turned on, so new group numbers are automatically set. Settings made using the switches will be overwritten.
(3) Settings when recovering from a power outage (SW2-4)This selects whether to restart operation when the power comes back on after a power outage occurred during operation. This setting is given priority in cases where the indoor unit has an auto start ON / OFF jumper. Note also that regardless of whether switch SW2-4 is on or off, the operating mode, set temperature, fan direction and speed settings, and remote control prohibition status are stored.
NOTE1: Since central equipment and HA JEM-A-compatible equipment both use last command priority, the contact status and operating status of the air conditioner might not match sometimes.Example: If the unit is run from the central controller while the air
conditioner is stopped with an open contact, the contact will be open and the unit will be running.
NOTE2: Operating mode and fan direction and speed settings can be changed.
(4) Contact input function settings (SW3-1 to SW3-2)When using contact input (S1), choose one of the following functions.
NOTE also that a separate timer power source is needed when using the schedule timer independently.Power source specs: DC 16V, +10%, -15%, 200mA.Recommended power source: Omron S82J-01015A. (Should be used with the output voltage adjusted to the center, DC 16V.)

Example of Control by Remote Controller
Note:1. If the system structure displaces the SkyAir's wired remote controller with a wireless remote controller,
the same control can be carried out.2. Impossible to structure with twin wireless remote controllers in case of the control adopting double
remote controllers. Be sure to use a wired remote controller for the one of the two controllers.
Double Remote ControllersOne indoor unit is controlled by double remote controllers from two separate locationsThis is a convenient system, when you want to operate an indoor unit in a living room from a porch, for example, or finely operate an indoor unit from a local or remote location. (The same applies to other types of indoor units.)
Operation control mode of the indoor unit has last command priority.Remove the front panel of the remote controller and set the MAIN/SUB changeover switch on the PC board to “MAIN” for the main remote controller, and to “SUB” for the sub remote controller.
Remote control (Fundamental use)The most fundamental use which connects one indoor unit with one remote controller.
Control by double remote controllersThis is a convenient system, when you want to operate an indoor unit in a living room from a porch, for example, or finely operate an indoor unit from a local or remote location. (The same applies to other types of indoor units.)
Group ControlSimultaneous control of up to 16 units with a one remote controller
Remote ControlThe remote control wiring can be extended up to 500m. Accordingly, it is easy to concentrate the plural remote controller of indoor units installed in a room widely spread into one position.
Combined controlSimultaneous control with a total heat exchanger HRV is possible through the indoor unit linkage.

4.13.2 Example of System
Group ControlSimultaneous control of up to 16 units with a one remote controllerThis is a convenient system, when you want to simultaneously control several indoor units on the same settings for air conditioning a space with wide and single floor.
Wiring to a remote controller for group control has no polarity. So, P1 and P2 can be exchanged.All indoor units within the group have the same setting, and each indoor unit is controlled individually by its own built-in thermostat.Because the automatic address system is used, the address does not require the setting by a remote controller for group control.
Combined ControlSimultaneous control between HRV and SkyAir's indoor unit.This is a convenient system when the simultaneous control of SkyAir indoor unit with a total heat exchanger HRV is required.
Since the remote controller's wiring doesn't have polarity, opposite positioning between P1 and P2 is allowed.
One remote controller can conduct the simultaneous control up to 16 units (SkyAir indoor units + HRV = 16 units)
