Convenience Outlets
Two types of convenience outlets are offered on 580J models:
Non-unit powered and unit-powered. Both types provide a 125-
volt GFCI (ground-fault circuit-interrupter) duplex receptacle
rated at 15-A behind a hinged access cover, located on the corner
panel of the unit. See Fig. 27.

INSTALLING WEATHERPROOF COVER — A weath-
erproof while-in-use cover for the factory-installed convenience
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 gas-
ket.
Disconnect all power to unit and convenience outlet.
Lock-out and tag-out all power.
Remove the blank cover plate at the convenience outlet; dis-
card the blank cover.
Loosen the two screws at the GFCI duplex outlet, until ap-
proximately 1 /
2
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 over-tighten).
Mount the weatherproof cover to the backing plate as shown
in Fig. 28. 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.
Fig. 28 — Weatherproof Cover Installation
Non-powered type — Requires the field installation of a gener-
al-purpose 125-volt 15-A circuit powered from a source else-
where in the building. Observe national and local codes when se-
lecting wire size, fuse or breaker requirements and disconnect
switch size and location. Route 125-v power supply conductors
into the bottom of the utility box containing the duplex recepta-
cle.
Unit-powered type — A unit-mounted transformer which is
factory-installed to step-down the main power supply voltage to
the unit to 115-v at the duplex receptacle. This option also in-
cludes 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. If local codes permit, the transformer
primary leads can be connected at the line-side terminals on the
unit-mounted non-fused disconnect switch; this will provide
service power to the unit when the unit disconnect switch is
open. See Fig. 29. See Fig. 30 for convenience outlet utilization
precautions.
WARNING
Failure to follow this warning could result in personal
injury or death.
Units with convenience outlet circuits may use multiple
disconnects. Check convenience outlet for power status
before opening unit for service. Locate its disconnect
switch, if appropriate, and open it. Lock-out and tag-out
this switch, if necessary.
