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 203/1/60 switch RED and ORG leads at L1
and insulate RED lead.
Transformer is energy limiting or may have 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 Complete C

board standoffs and screws to control box.
(Ground available from top two standoffs as
shown.)
