NOTES:
1. Compressor and blower motor thermally protected
internally.
2. All wiring to the unit must comply with NEC and
local codes.
3. 208/230 v transformers will be connected for
208 v operations. For 230 v operations, discon-
nect Red lead at L1, and attach Orange lead to
L1. Close open end of Red Lead with insulating
tape.
4. FP1 jumper provides freeze protection for
WATER. When using ANTI-FREEZE solutions, cut
FP1 jumper.
5. Typical thermostat wiring shown. Refer to thermo-
stat Installation Instructions for wiring to the unit.
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 standoffs and screws to control box.
(Ground available from top two standoffs as
shown.)
