Using Unit-Mounted Convenience Outlets
Units with unit-mounted 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-en-
ergization 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-re-
newable screw-in (Edison base) type plug fuse.
Duty Cycle
The unit-powered convenience outlet has a duty cycle lim-
itation. The transformer is intended to provide power on an
intermittent basis for service tools, lamps, etc; it is not intend-
ed 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. Convenience outlet us-
age 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 receptacle does not trip as required. Press the RE-
SET 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 accessories
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 name-
plate 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.

page 14.
Check tightness of connector lock nuts before connecting
electrical conduits.
Field-supplied and field-installed liquid tight conduit con-
nectors and conduit may be attached to the connectors on the
basepan. 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 exter-
nal 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 connections can be made. Connect the control power
conduit to the unit control box at this hole.
