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 460 v (BLK/RED) lead for 460/3/60 units. 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.Typical thermostat wiring shown. Refer to thermostat installation instructions for wiring to the unit. Ther- mostat wiring must be Class 1 and voltage rating equal to or greater than unit supply voltage.
6.Factory cut JW1 jumper. 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 voltages up to
9.Optional LON wires. Only connect if LON connection is desired at the wall sensor.
10.Fan motors are factory wired for medium speed. For high or low speed, remove BLU wire from fan motor speed tap “M” and connect to “H” for high speed or “L” for low speed.
11.For low speed, remove BLK wire from BR “6” and replace with RED. Connect BLK and BRN wires together.
12.For blower motors with leads. For medium or low speed, disconnect BLK wire from BR “6”. Connect BLK and ORG/PUR wire together. Connect RED for low or BLU for medium to BR “6”.
