NOTES:

1.Compressor and blower motor thermally protected internally.

2.All wiring to the unit must comply with NEC (National Electrical Code, U.S.A.) and local codes.

3.380/420-v transformers will be connected for 380-v operation. For 420-v operation, disconnect VIO lead at L1, and attach BRN lead to L1. Close open end of VIO lead.

4.FPI 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. Thermostat wiring

must be “Class 1” and voltage rating equal to or greater than unit supply voltage.

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 Complete C board standoffs and screws to control box. (Ground available from top two stand- offs as shown.)

8.Suffix 1 designates association with lead compressor. Suffix 2 with lag compressor.

9.For dual point power (DPP) option, blower wire will connect to other PBD.
