*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 240-V (ORG) lead for

240-1-50 units. For 220-1-50 operation, switch
the RED and ORG leads at L1 and insulate the
RED lead. Transformer is energy limiting or may
have a circuit breaker.

4. FP1 thermistor provides freeze protection for

WATER. When using anti-freeze solutions, cut
JW3 jumper.

5. Low voltage wiring must be class 1 and voltage

rated equal or greater than unit supply voltage.

6. Factory cut jumper (JW4). Dry contact will be

available between AL1 and AL2.

7. Transformer secondary ground via GRN/YEL

wire from C to control box.

8. See view A for wiring of units with water valve

(part no. 23B00112N01) or view B for units with
water valve (part no. 23B00112N03).
