The weatherproof cover kit is shipped in the unit’s control box.
The kit includes the hinged cover, a backing plate, and gasket.
1. Remove the blank cover plate at the convenience outlet; dis-
card the blank cover.
2. Loosen the two screws at the GFCI duplex outlet, until
approximately

-in. (13 mm) under screw heads is 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
5. Remove two slot fillers in the bottom of the cover to permit
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. Ob-
serve 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 utili-
ty 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 duplex re-
ceptacle. This option also includes a manual switch with fuse, lo-
cated in a utility box and mounted on a bracket behind the conve-
nience outlet; access is through the unit’s control box access panel.
See Fig. 39.
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 or HACR breaker switch; this will provide ser-
vice power to the unit when the unit disconnect switch or HACR
switch is open. Other connection methods will result in the conve-
nience outlet circuit being de-energized when the unit disconnect
or HACR switch is open. See Fig. 39.

Using Unit-Mounted Convenience Outlets
Units with unit-mounted convenience outlet circuits will often re-
quire that two disconnects be opened to de-energize all power to
the unit. Treat all units as electrically energized until the conve-
nience outlet power is also checked and de-energization is con-
firmed. Observe National Electrical Code Article 210, Branch Cir-
cuits, for use of convenience outlets.
Fuse On Power Type
The factory fuse is a Bussman
1
“Fusetron” T-15, non-renewable
screw-in (Edison base) type plug fuse.
Duty Cycle
The unit-powered convenience outlet has a duty cycle limitation.
The transformer is intended to provide power on an intermittent
basis for service tools, lamps, etc; it is not intended to provide
15 amps loading for continuous duty loads (such as electric heat-
ers for overnight use). Observe a 50% limit on circuit 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. 40.
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 receptacle
does not trip as required. Press the RESET button to clear the
tripped condition.
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.
