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--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. 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 methods will
result in the convenience outlet circuit being de--energized
when the unit disconnect or HACR switch is open. See
Fig. 19.
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
minutes of operation every hour).
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.

Fig. 19 -- Powered Convenience Outlet Wiring
Using unit--mounted convenience outlets: Units with
unit--mounded convenience outlet circuits 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” T--15, non--renewable screw--in (Edison base)
type plug fuse.
Factory--Option Thru--Base Connections —
This service connection kit consists of a
1
/
2
--in electrical
bulkhead connector and a
3
/
4
--in electrical bulkhead
connector, all factory--installed in the embossed (raised)
section of the unit basepan in the condenser section. The
1
/
2
--in bulkhead connector enables the low--voltage control
wires to pass through the basepan. The
3
/
4
--in electrical
bulkhead connector allows the high--voltage power wires
to pass through the basepan. See Fig. 20.
Check tightness of connector lock nuts before connecting
electrical conduits.
