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. Transformer wired to 460 v (BLK/RED) lead for 460/3/60 units

and 575 v (GRY) lead for 575/3/60. Transformer is energy limit-
ing or may have circuit breaker.

9. 208/230 v transformers will be wired for 208 v operation. For

230 v operation, disconnect RED lead at L1 and attach ORG
lead to L1. Close open end of RED lead with insulating tape.
