Notes:
1.

Compressor thermally protected internally.

2.

All wiring to the unit must comply with local codes.

3.

Transformer is wired to 240 V (ORG) lead for 240-1-50 units, switch RED and
ORG leads to PB(1) and insulate ORG lead for 220-1-50.

4.

FP1 thermistor provides freeze protection for water. When using anti-freeze
solutions, cut JW3 jumper.

5.

Check installation wiring information for specific thermostat hook-up. 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 JW4 jumper, and dry
contact will be available between AL1 and AL2.

7.

Transformer secondary ground via microprocessor board stand-offs and
screws to control box. (Ground available from top two stand-offs as shown.)

8.

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