*Optional wiring.
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 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 AL2
DRY (JW4) jumper and dry contact will be available between
AL1 and AL2.
7. Transformer secondary ground via Deluxe D board standoffs
and screws to control box. (Ground available from top two
standoffs as shown.)
