1-1. General Cautions

1. ELECTRICAL WORK

OK NO

Follow ordinance of your governmental organization for technical standard related to electrical equipment, wiringregulations, and guidance of each electric power company.Wiring for control (hereinafter referred to as transmission ) shall be (50mm[1-5/8in] or more) apart from power source

source wire in the same conduit.)Be sure to provide designated grounding work to outdoor unit.Give some allowance to wiring for electrical part box of indoor and outdoor units, because the box is sometimes removedat the time of service work.Never connect 208~230V power source to terminal block of transmission . If connected,electrical parts will be burntout.

Use 2-core shield cable for transmission . If transmission of different systems are wired with the same multiplecore cable, the resultant poor transmitting and receiving will cause erroneous operations.

2. M-NET CONTROL

The power to System controller (excluding LMAP03-U) is supplied via M-NET transmission line. M-NET transmission line at TB7 side is called Central control transmission line while one at TB3 side is called Indoor-Outdoor transmission line. There are 3 ways to supply power to the System controller .A) Connecting to TB3 of the Outdoor unit and receiving power from the Outdoor unit.B) Connecting to TB7 of the Outdoor unit and receiving power from the Outdoor unit. C) Connecting to TB7 of the Outdoor unit but receiving power from power supply unit PAC-SC51KUA.

Maximum 3 System controllers can be connected to TB3. If there is more than 1 Outdoor unit, it is necessary to replace power supply switch connector CN41 with CN40 on one Outdoor unit.

CAUTION


Fig. 2-3-3-CWhen using PAC-SC51KUA to supply transmission power, the power supply connector CN41 on the Outdoor units should be kept as it is. It is also a factory setting. 1 PAC-SC51KUA supports maximum 1 AG-150A unitdue to the limited power 24VDC at its TB3. However, 1 PAC-SC51KUA supplies transmission power at its TB2 equal to 5 Indoor units, which is referable at Table 2-3-2.If PZ-52SF, Timers, System controller, ON/OFF controller connected to TB7 consume transmission power more than 5 (Indoor units), Transmission booster PAC-SF46EPA is needed. PAC-SF46EPA supplies transmission power equal to 25 Indoor units.

AG-150A*1 is recommended to connect to TB7 because it performs back-up to a number of data. In an air conditioner system has more than 1 Outdoor units, AG-150A receiving transmission power through TB3 or TB7 on one of the Outdoor units would have a risk that the connected Outdoor unit failure would stop power supply to AG-150A and disrupt the whole system. When applying apportioned electric power function, AG-150A is necessary to connected to TB7 and has its own power supply unit PAC-SC51KUA.Note: Power supply unit PAC-SC51KUA is for AG-150A.*1: AG-150A is an example model of system controllers.

À Address No. of outdoor unit, indoor unit and remote controller.The address No. is set at the address setting board. In the case of R2 system, it is necessary to set the same No. at the branch No. switch of indoor unit as that of the BC controller connected. (When connecting two or more branches, use the lowest branch No.)

Á Caution for switch operations

Â MA remote controller

¥ Be sure to shut off power source before switch setting. If operated with power source on, switch can not operate properly.

¥ When connecting only one remote controller to one group, it is always the main remote controller. When connecting two remote controllers to one group, set one remote controller as the main remote controller

and the other as the sub remote controller.

¥ No units with identical unit address shall exist in one whole air conditioner system. If set erroneously, the system can not operate.

¥ The factory setting is Main .

3-2-2. PUMY-P-NHMU's refrigerant charging calculation

Example:

PUMY-P48NHMU

Original refrigerant charge for PUMY-P-NHMU is 8.5 kg [18.75 lbs], including 3 kg [106 oz] for 50 m [164 ft.] total extended piping length use. Thus, there is no need to charge additional refrigerant to the system if the total extended piping length is 50 m [164 ft.] or less.

If the total extended piping length is over 50 m [164 ft.], calculate the additional refrigerant using following procedure. Yet, if the calculated result is negative, no additional charge is needed.

4-1-1-1. General cautions 4-1-1-3. Foundation for PUMY-P-NHMUA. No direct thermal radiation to the unit.B. Select a location from which sound emitted by the unit will

not inconvenience the neighbors.C. Select a location permitting easy wiring and pipe access to

the power source and indoor unit.D. Avoid locations where combustible gases may leak, be

produced, flow, or accumulate.E. Note that water may drain from the unit during operation.F. Select a level location that can bear the weight and

vibration of the unit.G. Avoid locations where the unit can be covered by snow. In

areas where heavy snow fall is anticipated, special precautions such as raising the installation location or installing a hood on the air intake must be taken to prevent the snow from blocking the air intake or blowing directly against it. This can reduce the airflow and a malfunction may result.

H. Avoid locations exposed to oil, steam, or sulfuric gas.I. Use the transportation handles of the outdoor unit to

transport the unit. If the unit is carried from the bottom, hands or fingers may be pinched.

When installing the outdoor unit on a rooftop or other location unprotected from the wind, situate the air outlet of the unit so that it is not directly exposed to strong winds.Strong wind entering the air outlet may impede the normal airflow and a malfunction may result.The following shows two examples of precautions against strong winds. Install an optional air guide if the unit is installed in a

location where strong winds from a typhoon, etc. may directly enter the air outlet. (Fig. 4-1-1-2a) Air guide

Position the unit so that the air outlet blows perpendicularly to the seasonal wind direction, if possible. (Fig. 4-1-1-2b) Wind direction

A. Be sure to install the unit in a sturdy, level surface to prevent rattling noises during operation. (see Fig. 4-1-1-3)

B. Foundation specifications are as follows. Thickness of concrete Weight-bearing capacity Foundation bolt Bolt length 120 [4-3/4"] 320 kg [706lbs] M10 [3/8"] 70 [2-25/32"]C. Make sure that the length of the foundation bolt is within 30

mm [1-3/16"] of the bottom surface of the base.D. Secure the base of the unit firmly with four-M10 [3/8"]

foundation bolts in sturdy locations.

Warning:A. The foundation base should be strong enough to support

the outdoor unit, otherwise, it may fall down and cause damage or injures.

B. The unit must be installed according to the instructions in order to minimize the risk of damage from earthquakes, typhoons, or strong winds.

6. CAUTIONS

6-1. Refrigerant Properties

The installer and/or air conditioning system specialist shall secure safety against refrigerant leakage according to local regulations or standards.The following standard may be applicable if no local regulation or standard is available.

R410A refrigerant is harmless and incombustible. R410A is heavier than the indoor air in density. Leakage of the refrigerant in a room has possibility to lead to a hypoxia situation. Therefore, the critical concentration specified below shall not be exceeded even if the leakagehappens.

Critical concentrationCritical concentration is the maximum refrigerant concentration at which no harm would occur if immediate measures are taken whenrefrigerant leakage happens. Critical concentration of R410A: 0.30kg/m [0.0187 lbs./ft.3]3

(The weight of refrigeration gas per 1 m3 [1 ft.3] air conditioning space.);The critical concentration is per ISO5149, EN378-1 (other codes and standards may establish different values for critical concentration).

For CITY MULTI systems, the concentration of refrigerant leaked should not exceed the critical concentration in any situation.

6-2. Confirm the Critical Concentration and Perform CountermeasuresThe maximum refrigerant leakage concentration (Rmax) is defined as the result of the possible maximum refrigerant weight (Wmax)leaked into a room divided by its room capacity (V). It is referable to Fig. 5-1. The refrigerant weight includes its original charge andadditional charge at the site.The additional charge is calculated according to and shall not be over charged at the site .Procedure 6-2-1~3 tells how to confirm maximum refrigerant leakage concentration (Rmax) and how to take countermeasures against

Fig. 6-1 The maximum refrigerant leakage concentration6-2-1.Find the room capacity (V),

If a room having total opening area more than 0.15% of the floor area at a low position with another room/space, the two rooms/space areconsidered as one. The total space shall be added up.

6-2-2.Find the possible maximum leakage (Wmax) in the room. If a room has Indoor unit(s) from more than 1 Outdoor unit, add up the refriger-ant of the Outdoor units.

6-2-3.Divide (Wmax) by (V) to get the maximum refrigerant leakage concentration (Rmax).6-2-4.Find if there is any room in which the maximum refrigerant leakage concentration (Rmax) is over 0.30kg/m3 [0.087 lbs./ft.3].

If no, then the CITY MULTI is safe against refrigerant leakage.If yes, following countermeasure is recommended to do at site.Countermeasure 1: Let-out (making V bigger)

Design an opening of more than 0.15% of the floor area at a low position of the wall to let out the refrigerant whenever leaked.e.g. make the upper and lower seams of door big enough.

Countermeasure 2: Smaller total charge (making Wmax smaller) e.g. Avoid connecting more than 1 Outdoor unit to one room.e.g. Using smaller model size but more Outdoor units.e.g. Shorten the refrigerant piping as much as possible.

a possible leakage.

e.g. Remove unit from space.Countermeasure 3:

As the density of the refrigerant is bigger than that of the air.Ventilation air supply solution refers to Fig. 6-2~4.

Note 1. Countermeasure 3 should be done in a proper way in which the ventilation air supply shall be on whenever the leakage happens .Note 2. In principle, MITSUBISHI ELECTRIC requires proper piping design, installation and air-tight testing after installation to avoid leakage happening.

In the area should earthquake happen, anti-vibration measures should be fully considered.The piping should consider the extension due to the temperature variation.
