Using Unit-Mounted Convenience Outlets
Units with unit-mounted convenience outlet circuits will often
require that two disconnects be opened to de-energize all pow-
er 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
able screw-in (Edison base) type plug fuse.
Duty Cycle
The unit-powered convenience outlet has a duty cycle limita-
tion. The transformer is intended to provide power on an inter-
mittent 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 cir-
cuit loading above 8 amps. Convenience outlet usage rating:
• Continuous usage: 8 amps maximum
• Intermittent usage: Up to 15 amps maximum for up to
2 hours maximum
See Fig. 35.
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 re-
ceptacle does not trip as required. Press the RESET button to
clear the tripped condition.

HACR AMP RATING

The amp rating of the HACR factory-installed option is based
on the size, voltage, indoor motor and other electrical options
of the unit as shipped from the factory. If field-installed acces-
sories are added or changed in the field (for example, power
exhaust, ERV), the HACR may no longer be of the proper amp
rating and therefore will need to be removed from the unit. See
unit nameplate and label on factory-installed HACR for the
amp rating of the HACR that was shipped with the unit from
the factory (Fig. 36). See unit nameplates for the proper fuse,
HACR or maximum over-current protection device required on
the unit with field-installed accessories.

FACTORY-OPTION THRU-BASE CONNECTIONS (ELEC-
TRICAL CONNECTIONS)
This service connection kit consists of a
er fitting (brass), a 1 / -in. electrical bulkhead connector, and a
2
3 / -in. electrical bulkhead connector, all factory-installed in the
4
embossed (raised) section of the unit basepan in the condenser
section. The 3 / -in. bulkhead connector enables the low-voltage
4
control wires to pass through the basepan. The
bulkhead connector allows the high-voltage power wires to
pass through the basepan. See Fig. 18 on page 13.
Check tightness of connector lock nuts before connecting elec-
trical conduits.
Field-supplied and field-installed liquid tight conduit connec-
tors and conduit may be attached to the connectors on the base-
pan. Pull correctly rated high voltage and low voltage through
appropriate conduits. Connect the power conduit to the internal
disconnect (if unit is so equipped) or to the external disconnect
(through unit side panel). A hole must be field cut in the main
control box bottom on the left side so the 24-v control connec-
tions can be made. Connect the control power conduit to the
unit control box at this hole.
