A
weatherproof
while-in-use
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.

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- - v at the duplex receptacle. This
option also includes a manual switch with fuse, located in
C09119
a utility box and mounted on a bracket behind the
convenience outlet; access is through the unit's control
box access panel. See Fig. 18.
The primary leads to the convenience outlet transformer
cover
for
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. 20.

Duty Cycle: the unit- - powered convenience outlet has a
duty cycle limitation. The transformer is intended to
provide power on an intermittent basis for service tools,
lamps, etc; it is not intended to provide 15- - amps loading
for continuous duty loads (such as electric heaters for
overnight use). Observe a 50% limit on circuit loading
above 8- - amps (i.e., limit loads exceeding 8- - amps to 30
