REPLACEMENT PARTS ORDERING PARTS When reporting shortages or damages, or ordering repair parts, give the complete unit model and serial numbers as stamped on the unit’s nameplate. Replacement parts for this appliance are available through your contractor or local distributor. For the location of your nearest distributor, consult the white business pages, the yellow page section of the local telephone book or contact: CONSUMER AFFAIRS GOODMAN MANUFACTURING COMPANY, L.P.
MAJOR COMPONENTS The unit includes a hermetically sealed refrigerating system (consisting of a compressor, condenser coil, evaporator coil with flowrator), an indoor blower, a condenser fan and all necessary internal electrical wiring. The heat pump also includes a reversing valve, solenoid, defrost thermostat and control and loss of charge protection. The system is factory-evacuated, charged and performance tested. Refrigerant amount and type are indicated on rating plate.
CIRCULATING AIR AND FILTERS AIRFLOW CONVERSION Units can easily be converted from horizontal to down-discharge airflow delivery. In down-discharge or high static installations, the installer should measure the total external static and review the blower performance charts before performing the installation. In some installations it will be necessary to change the blower speed to provide proper air flow. Horizontal Air Flow Single phase models are shipped without horizontal duct covers.
A duct system should be installed in accordance with Standards of the National Board of Fire Underwriters for the Installation of Air Conditioning, Warm Air Heating and Ventilating Systems, Pamphlets No. 90A and 90B. The supply duct from the unit through a wall may be installed without clearance. However, minimum unit clearances as shown in the appendix must be maintained. The supply duct should be provided with an access panel large enough to inspect the air chamber downstream of the heat exchanger.
INTERNAL WIRING IMPORTANT NOTE: Some single phase units are equipped with a single-pole contactor. Exercise caution when servicing as only one leg of the power supply is broken with the contractor. A diagram detailing the internal wiring of this unit is located on the electrical box cover. If any of the original wire supplied with the appliance must be replaced, the wire gauge and insulation must be the same as the original wiring. Transformer is wired for 230 volts on the 208/230 models.
6. Be sure the Owner is instructed on the unit operation, filter, servicing, correct thermostat operation, etc. The foregoing “Start-up Procedure and Check List” is recommended to serve as an indication that the unit will operate normally. HEAT PUMP START-UP PROCEDURE 1. Check the cooling mode for the heat pump in the same manner as above. The reversing valve is energized when the thermostat is placed in the cooling position. A clicking sound should be noticeable from the reversing valve.
When the heat pump is in the heating cycle, the outdoor coil is functioning as an evaporator. The temperature of the refrigerant in the outdoor coil must be below the temperature of the outdoor air in order to extract heat from the air. Thus, the greater the difference in the outdoor temperature and the outdoor coil temperature, the greater the heating capacity of the heat pump. This phenomenon is a characteristic of a heat pump.
8. The control is shipped from the factory with the compressor delay option selected. This will de-energize the compressor contactor for 30 seconds on defrost initiation and defrost termination. If the jumper is set to Normal, the compressor will continue to run during defrost initiation and defrost termination. The control will also ignore the low pressure switch connected to R-PS1 and PS2 for 5 minutes upon defrost initiation and 5 minutes after defrost termination.
The duct openings on the unit are considered internal static pressure. As long as ESP is maintained, the unit will deliver the proper air up to the maximum static pressure listed for the CFM required by the application (i.e. home, building, etc.) In general, 400 CFM per ton of cooling capacity is a rule of thumb. Some applications depending on the sensible and latent capacity requirements may need only 350 CFM or up to 425 CFM per ton.
EEM Motor SATURATED LIQUID PRESSURE TEMPERATURE CHART Adjust the CFM by changing the 24V low voltage lead at the speed terminal block on the motor. (T1-Low Speed, T2 and T3-Medium Speed, T4 and T5-High Speed).
EXPANSION VALVE (TXV) SYSTEM ELECTRICAL ADJUSTMENTS Two Speed Application (*PH1460) This series of electric cooling and, heat pump package equipment is designed to accept a field installed electric heat kit. The unit is equipped to easily install the HKP or HKR Series single phase Electric Heat Kits. Full Installation Instructions are included in this kit. Please use this document for guidance in field equipping the package unit with electric heat.
SERVICE POOR “TERMINATING” SENSOR CONTACT THE FOLLOWING INFORMATION IS FOR USE BY QUALIFIED SERVICE AGENCY ONLY: OTHERS SHOULD NOT ATTEMPT TO SERVICE THIS EQUIPMENT. The unit’s defrost terminating sensor must make good thermal contact with the outdoor coil tubing. Poor contact may not terminate the unit’s defrost cycle quickly enough to prevent the unit from cutting out on high discharge pressure. Common Causes of Unsatisfactory Operation of Heat Pump in the Heating Cycle.

PACKAGE UNITS - HEAT PUMP AND AC UNITS HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS We strongly recommend a bi-annual maintenance checkup be performed by a qualified service agency before the heating and cooling seasons begin. An alternate cleaning method is to use one of the products listed in the technical publication TP-109 (shipped in the literature bag with the unit) to clean the coils. The cleaners listed are the only agents deemed safe and approved for use to clean round tube aluminum coils.
