Two types of convenience outlets are offered on 580J
models: Non--powered and unit--powered. Both types
provide a 125-volt GFCI (ground--faul t circui t--interrupter)

Installing Weatherproof Cover
A weathe rproof 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 installation. For
shipment, the conve nience outlet is covered with a blank
cover plate.
The weatherproof cover kit is shipped in the unit’s cont rol
box. The kit includes the hinged cover, a backing plate
and gasket.
IMPORTANT: Disconnect all power to unit a nd
conveni ence outlet.
1. Remove the blank cover pla te at the convenience out-
let; di scard 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 exposed.
3. Press the gasket over the screw heads. Slip the back-
ing plate over the screw heads at 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.

Non--Pow ered Ty pe
This type requires the field installation of a
genera l--purpose 125--volt 15--A circuit powered from a
source elsewhere in the building. Observe national and
local codes when selecting wire size, fuse or breaker
requirements a nd disconnect switch size and location.
Route 125--v power supply conductors into the bottom of
the utility box containing the duplex receptacle.
Unit--Powered Type
A unit--mount ed 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. 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 te rminals on a unit--mounted non--fused
disconnect or circuit--breake r switch; this will provide
service power to the unit when the unit disconnect switch
or ci rcuit--breaker is open. Other connection methods will
result in the convenience outlet circuit being de--energized
when the unit disconnect or circuit--bre aker is open. (See
Fig. 18.)
