NOTES:
1. Compressor and Blower Motor thermally protected
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. Trans-
former 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
AL2DRY (JW4) Jumper and Dry Contact will be avail-
able 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.)
