NOTES:

1.Compressor and blower motor thermally protected internally.

2.All wiring to the unit must comply with local codes.

3.Transformer is wired to 115-V (WHT) lead for 115/1/60 units; 265-V (BRN) lead for 265/1/60 units; or 208-V (RED) lead for 208/1/60 units.

For 230/1/60 operation, switch the RED and ORG leads at L1 and insulate the RED lead.

Transformer is energy limiting or may have a circuit breaker.

4.FP1 thermistor provides freeze protection for WATER. When using ANTI-FREEZE solutions, cut JW3 jumper.

5.Typical heat pump thermostat wiring shown. Refer to thermostat Installation Instructions for wiring to the unit.

6.24-V alarm signal shown. For dry alarm contact, cut JW1 jumper and dry contact will be available between AL1 and AL2.

7.Transformer secondary ground via Com- plete C board standoffs and screws to control box. (Ground available from top two standoffs as shown.)
