InstallingWeatherproof Cover –
A weatherproof while-in-use cover for the
factory-installed convenience outlets is now required by
UL standards. This cover cannot be factory-mounted due
its depth; it must be installed at unit installation. 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
CONVENIENCE OUTLET.
Remove the blank cover plate at the convenience outlet;
discard the blank cover.
Loosen the two screws at the GFCI duplex outlet, until
approximately 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
shownin Fig. 18. Remove two slot fillers in the bottom of
the cover to permit service tool cords to exit the cover.
Check forfull closing and latching.

Fig. 18 --Weatherproof Cover Installation
Non--powered type: This type requires the field
installation of a general--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 and 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--mounted transformer is
factory--installed to stepdown the main power supply
voltage to the unit to 115--vat the duplex receptacle. This
option also includesa 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 accesspanel. See Fig. 17.
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 or HACR breaker switch; this will provide
service power to the unit when the unit disconnect switch
or HACR switch is open. Other connection me thods will
result in the convenience outlet circuit being de--energized
when the unit disconnect or HACR switch is open. See
Fig. 19.
