CONVENIENCE OUTLETS
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. 36.

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. 37.
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. Ob-
serve 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 utili-
ty 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 duplex re-
ceptacle. This option also includes a manual switch with fuse, lo-
cated in a utility box and mounted on a bracket behind the conve-
nience outlet; access is through the unit’s control box access panel. 
See Fig. 36.
The primary leads to the convenience outlet transformer are not 
factory-connected. Selection of primary power source is a custom-
er 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 cir-
cuit being de-energized when the unit disconnect or HACR switch 
is open. See Fig. 38.
WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury or 
death.
Units with convenience outlet circuits may use multiple 
disconnects. Check convenience outlet for power status before 
opening unit for service. Locate its disconnect switch, if 
appropriate, and open it. Tag-out this switch, if necessary.
