NOTES:

1.Compressor and blower motor thermally protected internally.

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

3.208/230 v transformer will be connected for 208 v operation. For 230 v operation, disconnect RED lead at L1 and attach ORANGE lead to L1. Insulate open end of RED lead. Transformer is energy limiting or may have circuit breaker.

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

5.Check installation wiring information for specific thermostat hookup. 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 standoffs as shown.)

8.Aquastat is supplied with unit and must be wired in series with the hot leg to the pump. Aquastat is rated for voltage up to 277 v.
