FIELD INSTALLED HEATER PACKAGES (OPTIONAL) These packaged heat pumps are manufactured without supplementary electric heaters. Supplementary heaters EH3P series (to fit PH1224, PH1230, and PH1236) are available for simple, fast, field installation. A separate field power circuit is required for the supplementary heaters. -

Page 7: Installation
LOCATION GENERAL The unit must be located outside, or in a well ventilated area. It must not be in the space being heated or cooled. A sound absorbing material should be considered if the unit is to be installed in such a position or location that might cause transmission of sound or vibration to the living area or adjacent buildings. -

Page 10: Condensate Drain Trap
CONDENSATE DRAIN TRAP It is very important to provide a trap in the condensate drain line to allow a positive liquid seal in the line and assure correct drainage from the coil condensate pan. Install condensate drain trap shown in Figure 7. Use drain connection size or larger. -
Page 11: Wiring - Main Power
WIRING – MAIN POWER Refer to the unit rating plate for wire sizing information and maximum fuse size. Each outdoor unit is marked with a “Minimum Circuit Ampacity”. This means that the field wiring used must be sized to carry that amount of current. If field installed heaters are added to the basic unit, a second separate power supply circuit will be required. -
Page 12: Thermostats
THERMOSTATS See specific wiring information for the different models, heater KWs, and voltages. No automatic changeover position – must be manually placed in heat or cool. Reversing valve remains energized at all times system switch is in heat position (except during defrost cycle). No pressure equalization noise when thermostat is satisfied on either heating or cooling. -
Page 13: Thermostat Indicator Lamps
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. -
Page 14: Start Up And Operation
THREE PHASE SCROLL COMPRESSOR START UP INFORMATION Scroll compressors, like several other types of compressors, will only compress in one rotational direction. Direction of rotation is not an issue with single phase compressors since they will always start and run in the proper direction. However, three phase compressors will rotate in either direction depending upon phasing of the power. -

Page 16: Service And Troubleshooting
SERVICE AND TROUBLESHOOTING SERVICE HINTS 1. Caution homeowner to maintain clean air filters at all times. Also, not to needlessly close off supply and return air registers. This reduces air flow through the system which shortens equipment service life as well as increasing operating costs. -

Page 18: Checking Temperature Sensor Check Out
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. TEMPERATURE F vs RESISTANCE R OF TEMPERATURE SENSOR Manual 2100-344 Page 3. -
Page 19: Suction And Discharge Tube Brazing
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. -
Page 20: Pressure Tables
COOLING HEATING Low side pressure ± 2 PSIG High side pressure ± 5 PSIG Tables are based upon rated CFM (airflow across the evaporator coil and should be found under section titled “Refrigerant Charge” elsewhere in manual. If there is any doubt as to correct operating charge being in the system, the charge should be removed, system evacuated, and recharged to serial plate instructions. -
