NOTES:
1.Compressor and blower motor thermally protected internally.
2.All wiring to the unit must comply with NEC (National Electrical Code) and local codes.
3.
4.FP1 thermistor provides freeze protection for WATER. When using ANTIFREEZE solu- tion, cut JW3 jumper.
5.Typical heat pump thermostat wiring shown. Refer to thermostat installation instructions for wiring to the unit. Thermostat wiring must be “Class 1” and voltage rating equal to or greater than unit supply voltage.
6.
7.Transformer secondary ground via Deluxe D board standoffs and screws to control box. (Ground available from top two standoffs as shown.)
8.For dual point power option, blower wires (3 qty) will go to PDB2 only.
