1. Remove the blank cover plate at the convenience outlet;
discard the blank cover.
2. Loosen the two screws at the GFCI duplex outlet, until
approximately
1
/

3. Slip the backing plate over the screw heads at the key-
hole slots and align with the gasket; tighten the two
screws until snug (do not over-tighten).
4. Mount the weatherproof cover to the backing plate as
shown in Fig. 27.

Using Unit-Mounted Convenience Outlets
Units with unit-mounted convenience outlet circuits will
often require that two disconnects be opened to de-energize
all power to the unit. Treat all units as electrically energized
until the convenience outlet power is also checked and de-en-
ergization is confirmed. Observe National Electrical Code
Article 210, Branch Circuits, for use of convenience outlets.
HACR AMP RATING
The amp rating of the HACR factory-installed option is based
on the size, voltage, indoor motor and other electrical options of
the unit as shipped from the factory. If field-installed accessories
are added or changed in the field (for example, power exhaust,
ERV), the HACR may no longer be of the proper amp rating and
therefore will need to be removed from the unit. See unit name-
plate and label on factory-installed HACR for the amp rating of
the HACR that was shipped with the unit from the factory
(Fig. 28). See unit nameplates for the proper fuse, HACR or
maximum over-current protection device required on the unit
with field installed accessories.

FACTORY-OPTION THRU-BASE CONNECTIONS
This service connection kit consists of a
1
/
2
-in. electrical
bulkhead connector and a 1
1
/
4
-in. electrical bulkhead con-
nector, all factory-installed in the embossed (raised) section
of the unit basepan in the condenser section. The
1
/
2
-in. bulk-
head connector enables the low-voltage control wires to pass
through the basepan. The 1
1
/
4
-in. electrical bulkhead connec-
tor allows the high-voltage power wires to pass through the
basepan. See Fig. 29.

Check tightness of connector lock nuts before connecting
electrical conduits
Field-supplied and field-installed liquid-tight conduit con-
nectors and conduit may be attached to the connectors on the
basepan. Pull correctly rated high voltage and low voltage
through appropriate conduits. Connect the power conduit to
the internal disconnect (if unit is so equipped) or to the exter-
nal disconnect (through unit side panel). A hole must be field
cut in the main control box bottom on the left side so the 24-v
control connections can be made. Connect the control power
conduit to the unit control box at this hole.
UNITS WITHOUT THRU-BASE CONNECTIONS
1. Install power wiring conduit through side panel open-
ings. Install conduit between disconnect and control box.
2. Install power lines to terminal connections as shown in
FIELD CONTROL WIRING
The 50HC unit requires an external temperature control
device. This device can be a thermostat (field-supplied) or a
PremierLink™ controller (available as factory-installed op-
tion or as field-installed accessory, for use on a Carrier Com-
fort Network
®
(CCN) or as a stand-alone control) or the RTU
