---------- Field Line Voltage Wiring
Field Low-Voltage Wiring
*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 cir-
cuit 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 con-
tact, 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.)
