NOTICE
Convenience Outlet Utilization
Maximum Intermittent use : 15 Amps 2 to 3 Hours
Maximum Continuous use : 8 Amps 24/7
Fig. 33 - - Convenience Outlet Utilization Notice Label
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.
Convenience outlet usage rating:
Continuous usage: 8 amps maximum
Intermittent usage: up to 15 amps maximum for
up to 2 hours maximum
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.

HACR —
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 (i.e., 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. 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 (Electrical
Connections)—
This service connection kit consists of a
adapter fitting (brass), a
3
connector and a / - - in electrical bulkhead connector, all
4
factory- - installed in the embossed (raised) section of the
unit basepan in the condenser section. The
bulkhead connector enables the low- - voltage control wires
to pass through the basepan. The
bulkhead connector allows the high- - voltage power wires
to pass through the basepan. See Fig. 16.
Check tightness of connector lock nuts before connecting
electrical conduits.
Field- - supplied and field- - installed liquid tight conduit
connectors 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 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 connections can be made.
Connect the control power conduit to the unit control box
at this hole.
