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 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.
WARNING
Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation. There
may be more than one disconnect switch. Tag all disconnect
locations to alert others not to restore power until work is
completed.
1. Remove the blank cover plate at the convenience outlet;
discard the blank cover.
2. Loosen the two screws at the GFCI duplex outlet, until
approximately -in. (13 mm) under screw heads is
1/
2
exposed. Press the gasket over the screw heads.
3. 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).
4. Mount the weatherproof cover to the backing plate as
shown in Fig. 36.
5. Remove two slot fillers in the bottom of the cover to per-
mit service tool cords to exit the cover.
6. Check for full closing and latching.

Non-Powered Convenience Outlet
This type requires the field installation of a general-purpose
125-v 15A 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 Convenience Outlet
A unit-mounted transformer is factory-installed to step down
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. 37.
The primary leads to the convenience outlet transformer are not
factory-connected. Selection of primary power source is a cus-
tomer 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 methods will result in the convenience outlet circuit
being de-energized when the unit disconnect switch is open. See
Fig. 37.

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. Convenience outlet usage rating:
• Continuous usage: 8 amps maximum
• Intermittent usage: Up to 15 amps maximum for up to
2 hours maximum
See Fig. 38.
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 re-
ceptacle does not trip as required. Press the RESET button to
clear the tripped condition.
