Unit-powered type: A unit-mounted transformer is facto-
ry-installed to stepdown the main power suppl 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. 29.
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; this will provide service power
to the unit when the unit disconnect switch is open. Other con-
nection methods will result in the convenience outlet circuit be-
ing de-energized when the unit disconnect switch is open. See
Fig. 31. On a unit without a unit-mounted disconnect, connect
the source leads to the main terminal block (TB1).
If the convenience outlet transformer is connected to the
line side of a field disconnect, the conduit provided with the
unit must be used to protect the wire as they are routed from the
transformer to the field disconnect. The end of the conduit with
the straight connector attaches to the field disconnect. The oth-
er end does not need to connect to the transformer; however,
the conduit must be routed so that all wiring is either in the con-
duit or behind the access panel.
If the convenience outlet transformer is connected to the
line side of the factory disconnect option, route the wires
through the web bushing located on the bottom of the discon-
nect box. For the load side wiring to the factory option discon-
nect, route the wires through the hole on the right side of the
disconnect. Be sure to create a drip loop at least 6-in. long.
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.

ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
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 con-
venience outlet power is also checked and de-energization
is confirmed. Observe National Electrical Code Article
210, Branch Circuits, for use of convenience outlets.
use cover for the factory-installed convenience outlets is now
required by UL standards. This cover cannot be factory-mount-
