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 connection methods will
result in the convenience outlet circuit being de-energized when
the unit disconnect switch is open. See Fig. 46. On a unit without a
unit-mounted disconnect, connect the source leads to the main ter-
minal 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 con-
nector attaches to the field disconnect. The other end does not
need to connect to the transformer; however, the conduit must be
routed so that all wiring is either in the conduit or behind the ac-
cess 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 disconnect box. For the load
side wiring to the factory option disconnect, route the wires
through the hole on the right side of the disconnect. Be sure to cre-
ate 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.
Fuse on power type: The factory fuse is a Bussman
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-
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-energization is confirmed.
Observe National Electrical Code Article 210, Branch Cir-
cuits, for use of convenience outlets.
Installing Weatherproof Cover
A weatherproof while-in-use cover for the factory-installed conve-
nience outlets is now required by UL standards. This cover cannot
be factory-mounted due to its depth; it must be installed at unit in-
stallation. 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.
DISCONNECT ALL POWER TO UNIT AND CONVE-
NIENCE OUTLET. LOCK-OUT AND TAG-OUT ALL
POWER.
Remove the blank cover plate at the convenience outlet; discard
the blank cover.
Loosen the two screws at the GFCI duplex outlet, until approxi-
mately / -in. (13 mm) under screw heads is 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 over-tighten).
Mount the weatherproof cover to the backing plate as shown in
Fig. 47. Remove two slot fillers in the bottom of the cover to per-
mit service tool cords to exit the cover. Check for full closing and
latching.
