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, 240-V (ORG) lead for 240/1/50 units, or 208-V (RED) lead for 208/1/60 units.

Rewire transformer L1 connection if voltage is 230-1-60 or 220-1-50, insulate unused lead.

4.FP1 thermistor provides freeze protection for WATER. When using ANTI-FREEZE solutions, cut JW3 jumper.

5.Refer to Microprocessor Control Installation, Application, and Operation manual for control wiring to the unit. Low voltage wiring must be “class 1” and voltage rated equal to 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 Deluxe D board standoffs and screws to control box. (Ground available from top 2 standoffs as shown.)
