NOTES:

1.Compressor and blower motor thermally protected internally.

2.All wiring to the unit must comply with NEC and local codes.

3.Transformer is wired to 240 v (ORG) lead for 240/50/1 units, switch RED and ORG leads to PB(3) and insulate ORG lead.

4.FP1 thermistor provides freeze protection for water. When using antifreeze solutions, cut JW3 jumper.

5.Typical heat pump thermostat wiring shown. Refer to thermostat installation instructions for wiring to the unit.

6.24-v alarm signal shown. For dry alarm contact, cut JW1 jumper, and dry contact will be available between AL1 and AL2.

7.Transformer secondary ground via microprocessor board stand- offs and screws to control box. (Ground available from top two standoffs as shown.)

8.Fan motors factory wired for medium speed. For high or low speed remove BLU wire from fan motor speed tap “M” and con- nect to “H” for high or “L” for low.
