*Optional wiring.
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 AL2 DRY (JW4) jumper and dry contact will be
available between AL1 and AL2.
7. Transformer secondary ground via Deluxe D board
standoffs and screws to control box. (Ground avail-
able from top two standoffs as shown.)
