NOTES:

1. Compressor and blower motor thermally protected internally.
2. All wiring to the unit must comply with NEC (National Electrical

Code) and local codes.

3. 208/230-v transformers will be connected for 208-v operation. For

230-v operation, disconnect RED lead at L1, and attach ORG
lead to L1. Close open end of RED lead.

4. FPI thermistor provides freeze protection for WATER. When using

ANTIFREEZE solutions, cut JW3 jumper.

5. Typical heat pump thermostat wiring shown. Refer to thermostat

installation instructions for wiring to the unit. Thermostat wiring
must be “Class 1” and voltage rating equal to or greater than unit
supply voltage.

6. Factory cut JW1 jumper and dry contact will be available between

AL1 and AL2.

7. Transformer secondary ground via Complete C board standoffs

and screws to control box. (Ground available from top two stand-
offs as shown.)
