*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.)
