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 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.)
