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 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. 14.

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. 15.

Fig. 15 -- Powered Convenience Outlet Wiring
The unit-powered convenience outlet has a 1000 VA rated
transformer. Maximum continuous current must not
exceed 8 Amps.
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.
Fuse on power type: The factory fuse is a Bussman
“Fusetron” T-15, non-renewable screw-in (Edison base)
type plug fuse.
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
Using unit-mounted convenience outlets: Units with
unit-mounded 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-energization is confirmed. Observe
National Electrical Code Article 210, Branch Circuits,
for use of convenience outlets.

WARNING
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 installed 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.

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 overtighten).
Mount the weatherproof cover to the backing plate as
shown in Fig. 16. 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.
