The PUG condensing units are cooling only models that aredesigned specifically for use with Mitsubishi Electronics PK,PC, and PL MR. SLIM indoor units of matching nominalcapacities. Models from 1.5 through 3.5 tons are available.
• QUALITY CONDENSER COILS - The coil is con-structed of enhanced copper tube and aluminum fins.
• COIL PROTECTION - Coils are protected from dam-age by a polymer mesh applied between the coil face and the PVC coated steel coil guard.
• PROTECTED COMPRESSOR - The compressor is internally protected against high pressure and temper-ature. This is accomplished by the simultaneous oper-ation of high and low pressure switches and a temperature sensor that protects the compressor if undesirable operating conditions occur. A liquid line fil-ter-drier further protects the compressor.
• DURABLE FINISH - The cabinet is made of pre-painted steel. The pre-treated flat galvanized steel pro-vides a better paint to steel bond, which resists corro-sion and rust creep. Special primer formulas and matted desert sand finish insure less fading when exposed to sunlight.
• LOWER INSTALLED COST - Installation time and costs are reduced by easy power and control wiring connections. Discharge line heat exchanger knock-outs are provided, if required. The unit contains enough refrigerant for matching indoor units and 25 feet of interconnecting piping. The small base dimen-sion means less space is required on the ground or roof.
• TOP DISCHARGE - The warm air from the top mounted fan is blown up away from the structure and any landscaping. This allows compact location on multi-unit applications.
• ADVANCED CONTROL BOARD - Each unit is equipped with an advanced electronic control board. This board controls the function of the outdoor unit and improves the operation and protection of the unit. The control board also provides operational and diagnostic information to the service technician through multiple LED’s.
• LOW OPERATING SOUND LEVEL - The upward air flow carries the normal operating noise up away from the living area. The rigid top panel effectively isolates any motor sound. Isolator mounted compressor and the rippled fins of the condenser coil muffle the normal fan motor and compressor operating sounds.
• LOW MAINTENANCE - Long life permanently lubri-cated motor-bearings need no annual servicing.
• EASY SERVICE ACCESS - Fully exposed refrigerant connections, a single panel covering the electrical con-trols and a plug in the control box connecting the con-denser fan, make for easy servicing of the unit.
• SECURED SERVICE VALVES - Secured reusable ser-vice valves are provided on both the liquid and vapor connections for ease of evacuating and charging.
• ETL LISTED - Approved for outdoor application.
• Certified in accordance with the Unitary Small Equip-ment certification program, which is based on ARI Standard 210/240.

SYSTEM CHARGEThe factory charge in the outdoor unit includes enoughcharge for the unit and the smallest matched evaporator and25 feet of line. Some evaporator matches may require someadditional charge. See Tabular Data sheet provided in unit lit-erature packet.The “TOTAL SYSTEM CHARGE” must be permanentlystamped on the unit data plate.Total system charge is determined as follows:1. Determine outdoor unit charge for the selected evapora-
tor from the corresponding table on Pages 4-6.2. If using line length other than 25 feet, calculate the line
charge from the tables on Page 24.
NOTE: The line charge over 25 feet should be included onthe data plate and must be added to the system.
3. Total system charge = item 1 + item 2.4. Permanently stamp the unit data plate with the total
amount of refrigerant in the system.Use one of the following charging methods whenever addi-tional refrigerant is required for the system charge.
MEASUREMENT METHODIf a calibrated charging cylinder or accurate weighing deviceis available, add refrigerant accordingly.
SUPERHEAT CHARGING METHODNOTE: Use this method only during system maintenanceand repair.
1. Operate system until temperatures and pressures stabi-lize (minimum of 10 minutes).
2. Measure and record indoor wet bulb (WB) temperature using a sling psychrometer and the outdoor dry bulb (DB) temperature using a thermometer.
Refrigerant charging should only be carried outby a qualified air conditioning contractor.
Compressor damage will occur if system isimproperly charged. On new system installationscharge system per R-22 charge information labeland follow guidelines in this instruction. Check flare caps on service ports to be sure theyare leak tight. DO NOT OVER TIGHTEN(between 40 and 60 inch - lbs. maximum).

3. Measure and record the suction pressure at the suction service valve port.
4. Using Table 1, note the superheat value corresponding to the intersection of the indoor wet bulb and the outdoor dry bulb.
5. With the superheat value obtained in step 4 and the suc-tion pressure value from step 3, find the intersection of the values in Table 2. This is the required suction tube temperature at the suction service valve.
6. To bring the tube temperature in line with the required value from Table 2, add refrigerant to the service port to cause the tube temperature to fall and reclaim refrigerant to cause the temperature to rise.

1. COOLING/HEATING OPERATIONOutdoor unit operation is activated by delivery of a 12VDC signal from the indoor unit. Cooling only units have 2 low voltagecontrol wires from the indoor unit to the outdoor unit. The functions of these wires are:
• Wire #1: Common
• Wire #2: Initiates operation of the compressor and outdoor fan when 12VDC is supplied from the indoor unit.
2. OUTDOOR ABNORMALITY DETECTION BY INDOOR UNIT (P8 FAULT CODE)A. The indoor unit constantly monitors the difference between return air temperature and indoor coil temperature. During
a call for cooling, if the indoor coil does not become at least nine degrees colder than the return air temperature afterapproximately ten minutes of operation, the indoor circuit board will shut down the system. The indoor unit will displaythe problem code “P8” at the indoor unit remote controller and terminate the 12VDC signal to the outdoor unit.
B. The “P8” code does not necessarily mean that the outdoor unit has a problem. It simply means that the indoor coil didnot become colder than the return air during a call for cooling.
C. If a “P8” code is displayed:i. Turn the indoor remote controller off and back on to reset it.ii. Set the remote controller to a “call” for cooling.iii. At the indoor unit 12VDC control terminals, check to see if 12VDC is present on the #1 and #2 wires.
1. You may encounter a 3-minute delay in cooling before the 12VDC signal is generated or after the 12VDC signalis delivered to the outdoor unit before the compressor contactor is energized.
iv. If 12VDC is present and the 3-minute delay has expired, the outdoor unit should be operating. If it is not, the indoor unit is not the source of the problem and the following should be checked:1. Check the 12VDC terminals at the outdoor unit for 12VDC. The polarity must be the same as that of the indoor.
That is, the control wires must be connected to matching numbered control terminations on the indoor and out-door units (1 to 1, 2 to 2). If the wires are not connected properly, the unit will not be damaged, but it will not oper-ate.a. If no 12VDC signal is present when 12VDC is available at the indoor unit, check for a break/open in the control
wire.b. If 12VDC is present, insure polarity is correct. If polarity is correct and a 12VDC signal is present, check the
LED indicators on the outdoor board.i. Is the “Status” LED lit constantly? If so, the outdoor board is in time delay. Wait for it to expire (make sure the
12VDC signal is still available from the indoor unit).ii. Is the “#2” LED lit? This indicates that the board is receiving 12VDC from the indoor unit.
NO LED: Recheck for 12VDC on the control wires, check for correct polarity and check the wires from the terminal block to the board.LED LIT: The board should be outputting 24 VAC to the compressor contactor and line voltage to the fan (unless in low ambient control). Is the compressor/fan operating?YES: System is OKNO: Is the “Status LED” flashing?NO: Bad outdoor boardYES: 2 Flash sequence indicates that the High Pressure Switch is open. 4 Flash sequence indicates that the Low Pressure Safety Switch is open
3. OUTDOOR BOARD FUNCTIONALITYA. High Pressure Safety Switch (HPSS). This switch opens at approximately 400 PSIG and closes at approximately
300 PSIG. There is no bypass on this switch. When the switch opens, the control immediately stops the compressorand outdoor fan. When the switch closes, the system can restart if the indoor unit has not entered a P8 fault code. Ifthe switch opens three times within a one-hour period, the outdoor unit operation is “locked out” and must be serviced.Turning line voltage off and back on to the outdoor unit will reset the lockout. The indoor unit must also be reset to clearthe fault code. Turning the remote controller off and back on will reset the indoor unit.
B. Low Pressure Safety Switch (LPS). This switch opens at approximately 7 PSI and closes at approximately 22 PSI.The switch is bypassed during the first 3 minutes of cooling operation. If the pressure rises to the “cut in” point, thecompressor will restart if the delay has expired and the indoor unit is not in a P8 fault. If the switch opens 3 times withina one-hour period, the outdoor unit will be “locked out” and must be serviced. Turning line voltage off and back on tothe outdoor unit will reset the lockout.

Mitsubishi Electronics 2003 27
C. Low Ambient Temperature Switch (LATS). The purpose of this switch is to extend cooling operation in low outdoortemperatures as low as 25°. The outdoor unit uses a high side pressure switch to cycle the fan. When pressure dropsto 165 PSI (+/-10), the switch opens and the fan stops. When pressure rises to 300 (+/- 10), the switch closes and thefan restarts. A jumper is factory installed in place of the low ambient pressure switch. This jumper must be removedwhen a low ambient accessory kit is installed. During low ambient cooling operation the indoor unit may initiate an “air defrost” of the indoor coil once during every 16 minutes of continuous cooling operation. This insures that the coil has adequate airflow and should not be considered as a fault.
D. Crankcase Heater (CCH) - A crankcase heater is installed into all PUG condensing units to protect the compressorwhen operating under low ambient conditions. When line voltage is first applied to the outdoor unit, the control willenergize the crankcase heater. The control will continue to energize the CCH until the first call for compressor opera-tion. The control never energizes the CCH during compressor operation. The control will energize the CCH thirty min-utes after the compressor turns off. It will then cycle the CCH on for 30 minutes and off for 30 minutes repeatedly untilthe compressor is again turned on.
E. Compressor Contactor (CC) - The compressor contactor is energized with 24VAC when a 12 VDC is input to the out-door unit on control wires 1 and 2 from the indoor unit. This 12 VDC signal is generated and sent from the indoor uniton all calls for compressor operation.
F. Outdoor Fan Motor (ODF) - The outdoor fan motor typically operates at the same time as the compressor. However,the fan may be off while the compressor is operating during low ambient cooling conditions as described previously.
G. Transformer Input (24VAC) - The secondary side of the transformer supplies 24 volts AC to the circuit board on the“24VAC” terminals. This voltage operates the internal circuits of the board and also provides voltage to the compressorcontactor when appropriate. The primary side of the transformer is powered with line voltage from terminals marked“L1” and “L2” on the board.
H. Line Voltage - Line voltage is input and output from the circuit board on the terminals marked “L1” and “L2”. There arefour terminals marked “L1”. These terminals provide “L1” input to the board and “L1” output to the transformer, crank-case heater and the outdoor fan motor.There are two terminals marked “L2”. One terminal provides “L2” line voltage input to the board. The other provides “L2” output to the transformer.
I. Anti-Recycle Delay Timer - The control provides an “anti-recycle delay” of three minutes in the cooling mode.J. Time Shortening - Placing the defrost jumper to the “TEST” position shortens timings of the control to the following
values.1. Anti-Recycle - 36 seconds2. CCH Cycles - 24 seconds3. Compressor Run - 1 second4. Low Pressure Bypass - 12 seconds
K. Last Fault Memory Recall. The control maintains a memory of the last fault that occurred. The last fault code can berecalled by moving the defrost jumper to the “TEST” position and observing the “STATUS” LED display. The controlstores only the last fault code. The control will reset the fault code memory when the line voltage to the outdoor unit isturned off.
L. LED Function. The board has four LED’s which provide the following function:1. “STATUS” LED indicates normal operation or faults as follows:
2. “CCH” LED indicates that the crankcase heater is energized.3. “2” LED indicates that the indoor unit is calling for compressor operation, 12VDC is present on control wire #2.
LED FLASHES INDICATION OF CONDITIONOff Normal Operation, no fault, no “call”
Constant on LED Anti-recycle delay active. If the HPSS or LPS opens, the anti-recycle will activate for 3 minutes before the fault can be displayed.

SERVICE PORTSThere are two service ports available to service technicians. One port is located at each of the two base valves.
A. Liquid Line Base Valve Service Port. This port is used to evacuate the refrigerant line set when the ball valve is inthe closed position. It may also be used to measure the liquid line pressure or, more accurately, the “saturated line”pressure during normal operation. During cooling operation this service port is downstream of the metering orificewhich is installed inside of the liquid line base valve body. While in the cooling mode this pressure is typically 25 to 40PSI above that of the suction base valve pressure (usually 85 to 110 PSI).
B. Suction Base Valve Service Port. This port is also used to evacuate the indoor unit and line set during installation.The ball valve must be closed to evacuate the line set and indoor unit. During normal cooling mode operation this pres-sure port indicates evaporator pressure (minus line set pressure drop). Typical cooling mode pressure readings hereare in the range of 55 to 80 PSI during summer operation.
C. Both refrigerant lines must be insulated because the “cooling side” metering device is located in the outdoorunit. Failure to insulate the liquid line, or more accurately the “saturation line”, will result in condensate dripping fromthe line and poor cooling performance.
D. Metering Devices. A fixed orifice that is located in the liquid base valve meters refrigerant in the cooling mode. If arestriction or a compressor failure occurs this orifice can be easily accessed and cleaned after refrigerant is recovered.It is important to use a back-up wrench on the liquid line base valve connections when accessing the orifice. Failure todo so could loosen the base valve connections and cause a refrigerant leak.
