ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
Using unit--mounted convenience outlets: Units with
unit--mounded 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--energization is confirmed. Observe
National Electrical Code Article 210, Branch Circuits,
for use of convenience outlets.
!
WARNING
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 gasket.
DISCONNECT ALL POWER TO UNIT AND
CONVENIENCE OUTLET. LOCK--OUT AND TAG--OUT
ALL POWER.
Remove the blank cover plate at the convenience outlet;
discard the blank cover.
Loosen the two screws at the GFCI duplex outlet, until
approximately 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. 27. 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.

1. Remove the “L” bracket assembly from the unit.
2. Remove connector plate assembly from the “L”
bracket and discard the “L” bracket, but retain the
washer head screws and the gasket (located between
the “L” bracket and the connector plate assembly).
NOTE: Take care not to damage the gasket, as it is
reused in the following step.
3. Place the gasket over the embossed area in the
basepan, aligning the holes in the gasket to the holes
in the basepan. See Fig. 29.
4. Install the connector plate assembly to the basepan
using 8 of the washer head screws.
NOTE: If electrical connections are not going to occur at
this time, tape or otherwise cover the fittings so that
moisture does not get into the building or conduit in the
interim.
