3.
Slip the backing plate over the screw heads at the key-
hole 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. 27.
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 125v 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 loca-
tion. Route 125v power supply conductors into the bottom
of the utility box containing the duplex receptacle.
Unit-Powered Convenience Outlet
transformer is factory-installed to step down the main pow-
er supply voltage to the unit to 115v at the duplex recepta-
cle. This option also includes a manual switch with fuse, lo-
cated 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. 26.
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 trans-
former primary leads can be connected at the line-side ter-
minals 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. 28.

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
convenience outlet power is also checked and de-energiza-
tion 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
"Fusetron"
1
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 heaters for overnight use). Ob-
serve 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
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 RE-
SET button to clear the tripped condition.
