NOTES:
1. Compressor and blower motor thermally protected internally.
2. All wiring to the unit must comply with NEC and local codes.
3. 208/230 v transformer will be connected for 208 v operation. For
230 v operation, disconnect RED lead at L1 and attach ORANGE
lead to L1. Insulate open end of RED lead. 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. 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 JW1 jumper
and 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 voltage up to 277 v.
9. Fan motors factory wired for medium speed. For high and low speed
remove BLU wire from fan motor speed tap ‘M’ and connect to ‘H’
for high or ‘L’ for low.
