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 265 v (BRN) lead for 265/1/60 units, or
208 v (RED) lead for 208/1/60. For 230/1/60 switch RED and
ORG leads at L1 and insulate 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. Typical Aquazone thermostat wiring shown. 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 control board standoffs and
screws to control box. (Ground available from top two standoffs
as shown.)
8. For high or low speed remove BLU wire from BR ‘NO’
and replace with BLK or RED wire respectively. Tape off unused
terminal.
9. Both DIP switches need to be in the ON position.
