NOTES: 1. Recommended for use on grounded power supply only. 2. Compressor and fan motor thermally protected. 3. Use copper conductors only. 4. All wiring must conform to NEC (National Electrical Code) and local codes. 5. Dashed boxes show start thermistor, reversing valve solenoid, and plug, when used. 6. Control center uses thermostat part number HH01AD045 or equivalent (Fig. 3, 6). 7. Field control wirie suitable for NEC, Class 2 control circuit at 24 volts (Fig. 3, 6).
