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 wiring
diagrams later in this section.
■ Install an adequately sized branch circuit disconnect,
according to the NEC, within sight of and readily accessible
from heat pump.
■ The cable or conduit and fittings connected from the
disconnect to the heat pump shall be rated for outdoor use.
