NOTES:
1. Compressor 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 or 575-v
GRY lead for 575-3-60 units. Transformer 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, or thermostat installation instruc-
tions for wiring to the unit. Wire “Y” from thermostat 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. Heat/cool
thermostats not compatible with motorized water valve.
6. 24-v alarm signal shown. For dry alarm contact, cut JW4 jumper and 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. 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 of speeds is available.
10. 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.
