Test the GFCI receptacle by pressing the TEST button on
the face of the receptacle to trip and open the receptacle. Check
for proper grounding wires and power line phasing if the GFCI
receptacle does not trip as required. Press the RESET button to
clear the tripped condition.

Fuse on power type: The factory fuse is a Bussman “Fuse-
tron” T-15, non-renewable screw-in (Edison base) type plug
fuse.
Installing Weatherproof Cover: 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 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 gas-
ket.
DISCONNECT ALL POWER TO UNIT AND CONVE-
NIENCE OUTLET. LOCK-OUT AND TAG-OUT ALL
POWER.
Remove the blank cover plate at the convenience outlet; dis-
card the blank cover.
Loosen the two screws at the GFCI duplex outlet, until ap-
proximately 1 /
2
-in. (13 mm) under screw heads are exposed.
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).
Mount the weatherproof cover to the backing plate as
shown in Fig. 47. Remove two slot fillers in the bottom of the
cover to permit service tool cords to exit the cover. Check for
full closing and latching.

Factory Option Thru-Base Connections — This service con-
nection kit consists of a 1 /
2
-in. electrical bulkhead connector
and a 1 1 /
2
-in. electrical bulkhead connector, connected to an
“L” bracket covering the embossed (raised) section of the unit
basepan in the condenser section. See Fig. 48. The 1 /
2
-in. bulk-
head connector enables the low-voltage control wires to pass
through the basepan. The 1 1 /
2
-in. electrical bulkhead connector
allows the high-voltage power wires to pass through the base-
pan.
WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
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 con-
venience outlet power is also checked and de-energization
is confirmed. Observe National Electrical Code Article
210, Branch Circuits, for use of convenience outlets.
