CONVENIENCE OUTLETS
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.
!
WARNING
Two types of convenience outlets are offered on 50LC
models: Non-powered and unit--powered. Both types
provide
a
125--volt
GFCI
(ground--fault
circuit--interrupter) duplex receptacle rated at 15--A
behind a hinged waterproof access cover, located on the
end panel of the unit. (See Fig. 14.)

Weatherproof Cover Installation
A
weatherproof
while-in-use
cover
for
the
factory-installed convenience outlets is now required by
UL standards. This cover cannot be factory-mounted due
to its depth. It 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.
IMPORTANT
: DISCONNECT ALL POWER TO UNIT
AND CONVENIENCE OUTLET.
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 are exposed.
3. Press the gasket over the screw heads.
4. 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).
5. Mount the weatherproof cover to the backing plate as
shown in Fig. 15.

6. Remove two slot fillers in the bottom of the cover to
permit service tool cords to exit the cover.
7. Check for full closing and latching.
Types of Convenience Outlets
Non--Powered Type
This type
requires the
field installation of a
general--purpose 125--volt 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
stepdown the main power supply voltage to the unit to
115--v at the duplex 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. 14.)
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 circuit--breaker switch; this will provide
service power to the unit when the unit disconnect switch
or circuit--breaker is open. Other connection methods will
result in the convenience outlet circuit being de--energized
when the unit disconnect or circuit--breaker is open. (See
Fig. 16.)
