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.
Using Unit-Mounted Convenience Outlets
Units with unit-mounted convenience outlet circuits will often re -
quire that two disconnects be opened to de-energize all power to
the unit. Treat all units as electrically energized until the conve -
nience outlet power is also checked and de-energization is con -
firmed. Observe National Electrical Code Article 210, Branch Cir -
cuits, for use of convenience outlets.
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 heat -
ers for overnight use). Observe a 50% limit on circuit 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. 55.

Notice Label
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, electric heat, power
exhaust), 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. 56). See unit nameplates for the proper fuse, HACR or maxi -
mum over-current protection device required on the unit with field
installed accessories.

FACTORY-OPTION THRU-BASE ELECTRICAL
CONNECTIONS
All units are equipped with the ability to bring utilities through the
base.
The electrical entrance is located in the control box area can be
accessed through the control box access panel. An embossed
area is provided with three knock outs. High voltage is brought
through the multi knock out by removing the appropriate size for
the size of the fitting required. A
7
/
8
-in. knock out is provided for
low voltage. An additional
7
/
8
-in. knock out is provided for a
115-v line, which is used when the unit is equipped with the non-
unit powered convenience outlet option.
All required fittings are field supplied. Install fittings when access
to both top and bottom of the base pan is available.
