FIELD CONNECTIONS CONTROL WIRING
1. Route low voltage wiring into bottom of control box as shown in
Figures 6 or 7. Make low voltage wiring connections inside the low
voltage box per Figures 8-9.
2. The complete connection diagram and schematic wiring label is
located on the inside surface of the unit service access panel.
3. Replace the control box cover removed in Step 2.
4. All field wiring to be in accordance with national electrical codes
(NEC) and/or local-city codes.
5. Mount the thermostat about 5 ft. above the floor, where it will be
exposed to normal room air circulation. Do not place it on an out-
side wall or where it is exposed to the radiant effect from exposed
glass or appliances, drafts from outside doors or supply air grilles.

6. Route the 24-volt control wiring (NEC Class 2) from the outdoor
unit to the indoor unit and thermostat.
To eliminate erratic operation, seal the hole in the wall at the ther-
mostat with permagum or equivalent to prevent air drafts affecting
the operation of in the thermostat.
A Start Assist Kit is available and recommended for long line set
applications or in areas of known low voltage problems.
