NOTES:
1. Compressor thermally protected internally.
2. All wiring to the unit must comply with NEC and local codes.
3. Transformer is wired to 240 v (ORG) lead for 240/50/1 units,
switch RED and ORG leads to PB(1) and insulate ORG lead for
220/50/1.
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 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
standoffs 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.
