NOTES:
1. Compressor and Blower Motor thermally pro-
tected internally.
2. All wiring to the unit must comply with NEC
and local codes.
3. Transformer is wired to 115V (WHT) lead for
115/1/60 units, 265V (BRN) Lead for 265/1/
60 units or 208V (RED) Lead for 208/1/60.
For 230/1/60 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 solu-
tions, 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 Con-
trol Box. (Ground available from top two
standoffs as shown.)
