Manual 2100-193O Page 15 of 26 WIRING — MAIN POWER Refer to the unit rating plate for wire sizing information and maximum fuse or “HACR Type” circuit breaker 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.

Manual 2100-193O Page 20 of 26 IMPORTANT INSTALLER NOTE For improved start-up performance, wash the indoor coil with a dishwashing detergent. CRANKCASE HEATERS All units are provided with some form of compressor crankcase heat.
Manual 2100-193O Page 21 of 26 PRESSURE SERVICE PORTS High and low pressure service ports are installed on all units so that the system operating pressures can be observed. Pressure tables can be found on Page 25 covering all models. It is imperative to match the correct pressure table to the unit by model number.
Manual 2100-193O Page 22 of 26 TROUBLESHOOTING SOLID STATE HEAT PUMP CONTROL TROUBLESHOOTING PROCEDURE 1. Turn on AC power supply to indoor and outdoor units. 2. Turn thermostat blower switch to “Fan On” – the indoor blower should start. (If it doesn't, troubleshoot indoor unit and correct problem).
Manual 2100-193O Page 23 of 26 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.
Manual 2100-193O Page 24 of 26 REFRIGERANT CHARGE The correct system R-22 charge is shown on the unit rating plate. Optimum unit performance will occur with a refrigerant charge resulting in a suction line temperature (6 inches from compressor) as shown in Table 9.
Manual 2100-193O Page 25 of 26 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” on Page 24 in manual.
