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 to its depth; it must be in-
stalled 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 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 approx-
1
imately / -in. (13 mm) under screw heads are exposed. Press
2
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. 28. Remove two slot fillers in the bottom of the cover to
permit service tool cords to exit the cover. Check for full clos-
ing and latching.

Non-Powered Type:
This type requires the field installation of a general-purpose
125-v 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 du-
plex 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. 27.
The primary leads to the convenience outlet transformer are not
factory-connected. Selection of primary power source is a custom-
er option. If local codes permit, the transformer primary leads can
be connected at the line-side terminals on the unit-mounted non-
fused disconnect switch; this will provide service power to the unit
when the unit disconnect switch is open. Other connection meth-
ods will result in the convenience outlet circuit being de-energized
when the unit disconnect switch is open. See Fig. 29.

Using Unit-Mounted Convenience Outlets:
Units with unit-mounted convenience outlet circuits will often
require that two disconnects be opened to de-energize all pow-
er 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.
Fuse on Power Type:
The factory fuse is a Bussman
able screw-in (Edison base) type plug fuse.
Duty Cycle:
The unit-powered convenience outlet has a duty cycle limita-
tion. The transformer is intended to provide power on an inter-
mittent basis for service tools, lamps, etc; it is not intended to
provide 15 amps loading for continuous duty loads (such as
electric heaters for overnight use). Observe a 50% limit on cir-
cuit loading above 8 amps.
