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 208 v (RED) lead for 208/3/60. For 230/3/60
switch RED and ORG leads at L1 and insulate RED lead.
4. FP1 thermistor provides freeze protection for water. When using anti-
freeze solutions, cut JW3 jumper.
5. Typical Aquazone thermostat wiring shown. Refer to thermostat installa-
tion 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 AL2 dry
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. Blower motor is factory wired for medium and high speeds.
For any other combination of speeds, attach the lower speed
wire to fan speed relay N.O. wire.
