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 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 avail-
able 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).
