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/:-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. 21. 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.

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 l15-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. 19.
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
the unit-mounted non-fused disconnect or 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
circuit being de-energized when the unit disconnect or
HACR switch is open. See Fig. 22.
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.
