Mount the weatherproof cover to the backing plate as shown in
Fig. 26. Remove two slot fillers in the bottom of the cover to per-
mit service tool cords to exit the cover. Check for full closing and
latching.

Non-Powered Type
Requires the field installation of a general-purpose 125-v 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 step-down 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 con-
venience outlet; access is through the unit's control box access
panel. See Fig. 25.
The primary leads to the convenience outlet transformer are not
factory-connected. Selection of primary power source is a custom-
er 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 methods will result in the
convenience outlet circuit being de-energized when the unit dis-
connect or HACR switch is open. See Fig. 27. On a unit without a
unit-mounted disconnect, connect the source leads to the main
terminal block (TB3).
If the convenience outlet transformer is connected to the line side
of a field disconnect, the conduit provided with the unit must be
used to protect the wires as they are routed from the transformer to
the field disconnect. The end of the conduit with the straight con-
nector attaches to the field disconnect. The other end does not
need to connect to the transformer; however, the conduit must be
routed so that all wiring is either in the conduit or behind the
access panel.
If the convenience outlet transformer is connected to the line side
of the factory disconnect option, route the wires through the web
bushing located on the bottom of the disconnect box. For the load-
side wiring to the factory option disconnect, route the wires

ALL UNITS

Test the GFCI receptacle by pressing the TEST button on the face
of the receptacle to trip and open the receptacle. Check for proper
grounding wires and power line phasing if the GFCI receptacle
does not trip as required. Press the RESET button to clear the
tripped condition.
Unit-Mounted Convenience Outlets
Outlets will often require that two disconnects be opened to de-
energize all power to the unit. Treat all units as electrically
energized until the convenience outlet power is also checked and
de-energization is confirmed. Observe National Electrical Code
Article 210, Branch Circuits, for use of convenience outlets.
Fuse on Power Type
The factory fuse is a Bussman "Fusetron"
screw-in (Edison base) type plug fuse. See Fig. 28 for maximum
continuous use amp limitations.
