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. 35. 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.
