SHIPPING DAMAGE Upon receipt of equipment, the carton should be checked for external signs of shipping damage. If damage is found, the receiving party must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier’s agent. GENERAL The equipment covered in this manual is to be installed by trained, experienced service and installation technicians. The refrigerant system is completely assembled and charged. All internal wiring is complete.
INSTALLATION INSTRUCTIONS OPTiOnal top outlet flange Top outlet flange is screwed to the back of the unit upon delivery. Flange must be installed on to the top of the unit before mounting. See Figure 3 for details. MOUNTING THE UNIT 1. These units are secured by wall mounting brackets which secure the unit to the outside wall surface at both sides. 2. The unit itself is suitable for 0 inch clearance. If a combustible wall use a minimum of 30" x 10" supply opening dimensions for sizing.

Rafters Unit (outside) Duct Supply Air Finished Ceiling WIRING – LOW VOLTAGE WIRING 230 / 208V, 1 phase and 3 phase equipment have 24V transformers with dual primary voltage. All equipment leaves the factory wired on 240V tap. For 208V operation, reconnect from 240V to 208V tap.
low voltage connections These units use a grounded 24 volt AC low voltage circuit and require at least a 2 stage heating and a 2 stage cooling thermostat. “G” terminal is the fan input. “Y” terminal is the compressor Stage 1 input. START UP These units require R-410A refrigerant & Polyol Ester oil. application: 1. Use separate service and manufacturing equipment to avoid cross contamination of oil and refrigerants. “Y1” terminal is the compressor Stage 2 input. 2.
START UP cont’d. safety practices: 1. Never mix R-410A with other refrigerants. 2. Use gloves and safety glasses, Polyol Ester oils can be irritating to the skin, and liquid refrigerant will freeze the skin. 3. Never use air and R-410A to leak check; the mixture may become flammable. 4. Do not inhale R-410A – the vapor attacks the nervous system, creating dizziness, loss of coordination and slurred speech.
PHASE MONITOR All units with three phase compressors are equipped with a 3 phase line monitor to prevent compressor damage due to phase reversal. The phase monitor in this unit is equipped with two LEDs. If the Y signal is present at the phase monitor and phases are correct, the green LED will light. If phases are reversed, the red fault LED will be lit and compressor operation is inhibited. If a fault condition occurs, shut off main power and reverse two of the supply leads to the unit.
DEFROST CYCLE The defrost cycle is controlled by temperature and time on the solid state heat pump control. 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 coil temperature sensor mounted near the bottom of the outdoor coil.
There is an initiate defrost jumper (sen jump) on the control that can be used at any outdoor ambient during the heating cycle to simulate a 0° coil temperature. This can be used to check defrost operation of the unit without waiting for the outdoor ambient to fall into the defrost region. By placing a jumper across the SEN JMP terminals (a ¼ inch QC terminal works best) the defrost sensor mounted on the outdoor coil is shunted out & will activate the timing circuit.
TROUBLESHOOTING SOLID STATE HEAT PUMP CONTROL TROUBLESHOOTING PROCEDURE 1. Note: A thorough understanding of the defrost cycle sequence is essential. Review that section earlier in this manual prior to troubleshooting the control. 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 OUTSIDE UNIT CIRCUIT 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.
compressor SOlenoid A nominal 24-volt direct current coil activates the internal compressor solenoid. The input control circuit voltage must be 18 to 28 volt ac. The coil power requirement is 20 VA. The external electrical connection is made with a molded plug assembly (PN 029-0311-00). This plug contains a full wave rectifier to supply direct current to the unloader coil.

Troubleshooting GE ECM™ Motors Symptom Caution: Disconnect power from unit before removing or replacing connectors, or servicing motor. To avoid electric shock from the motor’s capacitors, disconnect power and wait at least 5 minutes before opening motor.
Troubleshooting GE ECM™ Motors (Cont'd.) Replacing ECM Control Module To replace the control module for the GE variable-speed indoor blower motor you need to take the following steps: 1. You MUST have the correct replacement module. The controls are factory programmed for specific operating modes. Even though they look alike, different modules may have completely different functionality. Using the wrong control module voids all product warranties and may produce unexpected results. 2.
