NOTES:

1.

Compressor and blower motor thermally protected
internally.

2.

All wiring to the unit must comply with local codes.

3.

Transformer is wired to 115-V (WHT) lead for 115/1/60
units, 265-V (BRN) lead for 265/1/60 units or 208-V
(RED) lead for 208/1/60 units.
For 203/1/60 switch RED and ORG leads at L1 and insu-
late RED lead.
Transformer is energy limiting or may have circuit
breaker.

4.

FP1 thermistor provides freeze protection for WATER.
When using ANTI-FREEZE solutions, cut JW3 jumper.

5.

Typical unit-mounted thermostat wiring shown.

6.

24-V alarm signal shown. For dry alarm contact, cut AL2
DRY (JW4) jumper and dry contact will be available
between AL1 and AL2.

7.

Transformer secondary ground via Deluxe D board
standoffs and screws to control box. (Ground available
from top two standoffs as shown.)
