Fig. 21 -- 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
breake r 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 transformer is
fact ory--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. 20.
The primary l eads to the convenie nce 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
disconnec t or HACR breaker switch; this will provide
service power to the unit when the unit disconnect switch
or HACR switch is open. Other connection methods will
result in the convenience outlet circuit being de--energized
when the unit disconnect or HACR switch is open. See
Fig. 22.
