INSTALLATION LOCATION TYPICAL INSTALLATIONS GENERAL 1. ROOF MOUNTED – The unit is mounted on a sturdy base on the roof of the building. Return air to the unit is brought through a single return grille (grilles with built-in filters are best since they enable easy access for filter changing). Return air ducts are attached to the lower section of the front panel. Supply air is brought from the unit to attic duct work or to a furred down hall. Supply air duct is attached to the top of the front panel.
FIGURE 2 SLAB MOUNTING AT GROUND LEVEL 1 inch clearance between duct and any combustible material if distance between outside wall and unit is less than 3 feet (needed on electric heat units only). The distance between outside wall and unit varies with installation requirements.

5. OTHER INSTALLATIONS – Many other installations are possible with the packaged heat pump. No matter what the installation, always consider the following facts: A. Insure that the discharge air is not obstructed in any way so as to cause operation difficulties. B. The indoor coil drain pan is equipped with a coupling that must be piped through a condensate drain trap to a suitable drain. C. Always mount the unit is such a position that it may be easily reached for servicing and maintenance. D.

WIRING – MAIN POWER The unit rating plate lists a “Maximum Time Delay Fuse” or “HACR” type circuit breaker that is to be used with the equipment. The correct size must be used for proper circuit protection and also to assure that there will be no nuisance tripping due to the momentary high starting current of the compressor. Refer to the unit rating plate for wire sizing information and maximum fuse size. Each outdoor unit is marked with a “Minimum Circuit Ampacity”.
COMPRESSOR CUTOFF THERMOSTAT and OUTDOOR THERMOSTAT WIRING THERMOSTAT INDICATOR LAMPS The red lamp marked “EM. HT.” comes on and stays on whenever the system switch is placed in Em. Ht. position. The green lamp marked “Check” will come on if there is any problem that prevents the compressor from running when it is supposed to be. Heat pump compressor operation at outdoor temperatures below 0°F are neither desirable not advantageous in terms of efficiency.

START UP These units require R-410A refrigerant and Polyol Ester. SAFETY PRACTICES: 1. Never mix R-410A with other refrigerants. GENERAL: 1. Use separate service equipment to avoid cross contamination of oil and refrigerants. 2. Use gloves and safety glasses, Polyol Ester oils can be irritating to the skin, and liquid refrigerant will freeze the skin. 2. Use recovery equipment rated for R-410A refrigerant. 3. Never use air and R-410A to leak check; the mixture may become flammable. 3.
START UP AND OPERATION THREE PHASE SCROLL COMPRESSOR START UP INFORMATION (Models PH13362-B, PH13422-B, -C; PH13482-B, -C; PH13602-B, -C) All units with three phase scroll compressors are equipped with a three phase line monitor to prevent compressor damage due to phase reversal. The phase monitor in this unit is equipped with two LED’s. If the “Y” signal is present at the phase monitor and phases are correct, the green LED will light.
DEFROST CYCLE The defrost cycle is controlled by temperature and time on the solid state heat pump control. See Figure 9. When the outdoor temperature is in the lower 40°F temperature range or colder, the outdoor coil temperature is 32°F or below. This coil temperature is sensed by the defrost sensor mounted near the bottom of the outdoor coil. Once the Heat Pump Control board sees the resistance of the defrost sensor has been below the resistance of 34545 (30°F) for 60 minutes of accumulated run time.
TROUBLESHOOTING SOLID STATE HEAT PUMP CONTROL TROUBLESHOOTING PROCEDURE NOTE: A thorough understanding of the defrost cycle sequence is essential. Review that section earlier in this manual prior to troubleshooting the control. 1. Turn on AC power supply to unit. 2. Turn thermostat blower switch to “fan on” – the indoor blower should start. (If it doesn’t, troubleshoot indoor unit and correct problem.) 3. Turn thermostat blower to “auto” position. Indoor blower should stop.
CHECKING TEMPERATURE SENSOR CHECK OUT 1. Disconnect temperature sensor from board and from outdoor coil. 2. Use an ohmmeter and measure the resistance of the sensor. Also use ohmmeter to check for short or open. 3. Check resistance reading to chart of resistance; use sensor ambient temperature. (Tolerance of part is ± 10%.) 4. If sensor resistance reads very low, then sensor is shorted and will not allow proper operation of the heat pump control. 5.
SERVICE SERVICE HINTS FAN BLADE SETTINGS 1. Caution homeowner to maintain clean air filters at all times. Also, not to needlessly close off supply and return air registers. This reduces airflow through the system which shortens equipment service life as well as increasing operating costs. Shown in Figure 10 are the correct fan blade setting dimensions for proper air delivery across the outdoor coil. 2.

SUCTION AND DISCHARGE TUBE BRAZING Compliant Scroll compressors have copper plated steel suction and discharge tubes. These tubes are far more rugged and less prone to leaks than copper tubes used on other compressors. Due to different thermal properties of steel and copper, brazing procedures may have to be changed from those commonly used. • • To disconnect: heat joint Areas 2 and 3 slowly and uniformly until braze material softens and the tube can be pulled out of suction fitting. (See Figure 11.
TROUBLESHOOTING GE X13-SERIES ECM2.3™ MOTORS NOTE: Bard Models PH13242; PH13302; PH13362-A, -B; PH13422-A, -B, -C; PH13482-A, -B, -C; PH13602-A, -B, -C contain the X13-Series Motors. e. If the motor does not shut off at the end of the cycle, wait for any programmed delays to time out (no more than 90 seconds). Also make sure that there is no call for “Continuous Fan” on the "G" terminal. f.
TROUBLESHOOTING GE X13-SERIES ECM2.3™ MOTORS CONT’D. Model X13 Communication Diagnostics The X13 motor is communicated through 24 VAC low voltage (Thermostat Control Circuit Wiring). 1. Start with unit wiring diagram to confirm proper connections and voltage (see Figure 13). 2. Initiate a demand from the thermostat and check the voltage between the common and the appropriate motor terminal (1-5). ("G" input is typically on terminal #1, but refer to wiring diagram!) a.
