It is automatically energized by the manually operated supplemental heat switch in the indoor thermostat subbase. The thermostat locks out compressor and the relay bypasses the outdoor thermostats for electric heater operation during heat pump shutdown. When one outdoor thermostat is used, a supplemental heat relay is not required. The supplemental heat switch in the indoor thermostat subbase bypasses outdoor thermostat, locks out compressor and activates electric heater. 3. Unit is shipped with valve stem(s) frontseated, and caps installed. Replace stem caps after system is opened to refrigerant flow (backseated). Replace caps finger tight and tighten additional % turn with wrench. See sticker on valve cap. 4. Turn on main disconnect switch(es) to indoor and outdoor units. 5. Set fan switch as desired (ON or AUTO). 6. Set thermostat dial at desired temperature. 7. Set selector switch at HEAT or COOL. Operate unit for 15 minutes. 8. Check system refrigerant charge. See Refrigerant Charging. Motors and controls are designed to operate satisfactorily in the voltage range shown in Table 3. If necessary to use manifold gages for servicing, refer to Carrier Standard Service Techniques Manual, Chapter 1, Refrigerants, Pages 1-5, Fig. 8 for bypass method of returning charge to system. Removal of liquid line charging hose without following these precautions could result in some loss of charge. Refrigerant Charging (Fig. 7 through 14) A CAUTION To prevent personal injury, wear safety glasses and gloves when handling refrigerant. Do not overcharge system. This can cause compressor failure.
