TYPICAL WIRING SCHEMATICS

NOTES:

1.Compressor and fan motors are thermally protected 3-phase motors protected against primary single-phase condition.

2.If any original wires furnished must be replaced, it should be replaced with 90 C or its equivalent.

3.Numbers indicate the line location of used contacts. A bracket over 2 numbers signi- fies a single-pole double-throw contact. An underlined number signifies a normally closed contact.

4.Must use thermostat HH07AT170, 172 or 174 with subbase HN63AZ176, 177 or 178.

5.Separate field power supply required for electric heater accessory.

6.CLO locks out the compressor to prevent short cycling on compressor overloads and safety devices. Before replacing CLO check devices.
