WARNING
Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
IMPORTANT:
Electrical wiring, disconnect means and over-current
protection are to be supplied by the installer. Refer to the
rating plate for the maximum over-current protection,
minimum circuit ampacity and operating voltage. See the
wiring connection diagrams in "Troubleshooting."
Install an adequate sized branch circuit disconnect,
according to the NEC, within sight of and readily accessible
to heat pump or condensing unit.
The cable or conduit and fittings connected from the
disconnect switch to the heat pump or condensing unit wiring
connections shall be rated for outdoor use.
Check the heat pump or condensing unit rating plate to
determine whether the system is rated single phase or three
phase and follow the appropriate instructions for connecting
the pigtail leads.
Plug unused side entry holes with field-supplied plugs to
prevent moisture from entering the heat pump or condensing
unit.
Low voltage wiring must be separated from line voltage
wiring.
