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.)
