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 240 V (ORG) lead for 240-1-50 units. For 220-1-50
switch ORG and RED leads at PB(1) and insulate ORG 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 JW1 jumper, and dry
contact will be available between AL1 and AL2.
7.
Transformer secondary ground via Complete C board stand-offs and screws to
control box. (Ground available from top two stand-offs as shown.)
