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. Trans- former is energy limiting or may have circuit breaker.

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

5.Refer to microprocessor control, LON, thermostat installation instruc- tions for wiring to the unit. Wire “N01” from LON to “Y1” Deluxe D when motorized valve is not used. Thermostat wiring must be Class 1 and voltage rating equal to or greater than unit supply voltage.

6.Factory cut JW4 jumper. Dry contact will be available between AL1 and AL2.

7.Transformer secondary ground via green wire with yellow stripe from “C” terminal to control box.

8.Blower motor is factory wired for medium and high speeds. For any other combination of speeds, attach black wire to the higher of the two desired speed taps at the motor, and attach the blue wire to the lower of the two desired speed taps.

9.Blower motor is factory wired for high and low speeds. No other combi- nation is available.

10.Optional LON wires. Only connect if LON connection is desired at the wall sensor.

11.The 460-v units using an internal secondary pump will require a neutral wire from the supply side in order to feed the accessory with 265-v.
