*Optional wiring.
NOTES:
1. Compressor and blower motor thermally pro-
tected 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 unit-mounted thermostat wiring shown.
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.)
