CONVENIENCE OUTLETS
WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury or
death.
Units with convenience outlet circuits may use multiple dis-
connects. Check convenience outlet for power status before
opening unit for service. Locate its disconnect switch, if appro-
priate, and open it. Tag-out this switch, if necessary.
Convenience Outlets
Two types of convenience outlets are offered on 48FC models:
non-powered and unit-powered. Both types provide a 125 vac
ground-fault circuit-interrupt (GFCI) duplex receptacle rated at
15A behind a hinged waterproof access cover, located on the end
panel of the unit. See Fig. 32.

Installing Weatherproof Cover
A weatherproof while-in-use cover for the factory installed conve-
nience outlets is now required by UL standards. This cover cannot
be factory-mounted due to its depth. The cover must be installed at
unit installation. For shipment, the convenience outlet is covered
with a blank cover plate.
The weatherproof cover kit is shipped in the unit's control box.
The kit includes the hinged cover, a backing plate and gasket.
NOTE: DISCONNECT ALL POWER TO UNIT AND CONVE-
NIENCE OUTLET. Use approved lockout/tag-out procedures.
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 1/2-in. (13 mm) under screw heads is exposed.
3.
Press the gasket over the screw heads. Slip the backing
plate over the screw heads at the keyhole 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. 33.
5.
Remove two slot fillers in the bottom of the cover to per-
mit service tool cords to exit the cover.
6.
Check cover installation for full closing and latching.

Non-Powered Type
This type requires the field installation of a general-purpose
125-v 15-A circuit powered from a source elsewhere in the
building. Observe national and local codes when selecting wire
size, fuse or breaker requirements and disconnect switch size
and location. Route 125-v power supply conductors into the
bottom of the utility box containing the duplex receptacle.
Unit-Powered Type
A unit-mounted transformer is factory-installed to step-down
the main power supply voltage to the unit to 115-v at the du-
plex receptacle. This option also includes a manual switch with
fuse, located in a utility box and mounted on a bracket behind
the convenience outlet; access is through the unit's control box
access panel. See Fig. 32.
The primary leads to the convenience outlet transformer are
not factory-connected. Selection of primary power source is a
customer option. If local codes permit, the transformer primary
leads can be connected at the line-side terminals on a unit-
mounted non-fused disconnect or Heating, Air Conditioning
and Refrigeration (HACR) breaker switch; this will provide
service power to the unit when the unit disconnect switch or
HACR switch is open. Other connection methods will result in
the convenience outlet circuit being de-energized when the unit
disconnect or HACR switch is open. See Fig. 34.
