4.10 Power Wiring

It is important that proper electrical power is
available at the heat pump power terminal block. The
acceptable operating voltage range is shown below.
VOLTAGE RANGES
Nameplate Operating Voltage Range at
Voltage Maximum Load Conditions
Install a branch circuit disconnect within sight of the
unit and of adequate size to handle the minimum
circuit ampacity (MCA) current (see "Electrical Data"
in Section 3.2).
Field wiring must comply with the National Electric
Code (C.E.C. in Canada) and any applicable local code.
Power wiring must be run in a rain-tight conduit.
Conduit must be attached to the hole in the bottom
of the control box.
Connect power wiring to line-voltage lugs on the
terminal block located in the outdoor heat pump unit
electrical box. (See wiring diagram attached to unit
access panel.)
Check all electrical connections, including factory
wiring within the unit and make sure all connections
are tight.
DO NOT connect aluminum field wire to the line
voltage terminal block.
