WARNING
Two types of convenience outlets are offered on 580J
models: Non--powered and unit--powere d. Both types
provide a 125-volt GFCI (ground--fault circuit--interrupter)
duplex receptacle rated at 15-A behind a hinged
waterproof access cover, located on the end panel of the
unit. (See Fig. 16.)

Installing Weatherproof Cover
A weathe rproof while--in--use cover for the
factory--installed conve nience outlets is now required by
UL standards. This c over cannot be factory --mounted due
to its depth. It must be installed at unit installation. For
shipment, the convenience outlet is covered with a bla nk
cover plate.
The wea therproof cove r kit is shipped in the unit’s control
box. The kit includes the hinged cover, a bac king plat e
and gasket.
IMPORTANT: Disconnect all power to unit a nd
conveni ence outlet.
1. Remove the blank cover plate at the convenience out-
let; discard the blank cover.
2. Loosen the two screws at the GFCI duplex outlet, un-
til approximately 1/2--in (13 mm) under screw heads
are e xpose d.
3. Press the gasket over the screw heads. Slip the back-
ing plate over the screw heads a t the keyhole slots
and align with the gasket. Tighten the two screws un-
til snug (do not over--tighten).
4. Mount the weatherproof cover to the backing plate as
shown in Fig. 17.

5. 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.
Non--Powered Type
This type requires the field installation of a
genera l--purpose 125--volt 15--A ci rcuit 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 125--v power supply conductors into the bottom of
the utility box containing the duplex receptacle.
Unit--Powered Type
A unit--mounted tra nsformer 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. 16.)
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 a unit--mounted non--fused
disconnect or circuit--breaker switch; this will provide
service power to the unit when the unit disconnect switch
or circuit--breaker is open. Othe r connection methods will
result in the convenience outlet circuit being de--energized
when the unit disconnect or circuit--breaker is open. (See
Fig. 18.)
