Non- - unit 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 control box and mounted on a bracket behind the
convenience outlet; access is through the unit's control
box access panel. See Fig. 34.
The primary leads to the convenience outlet transformer
are not factory- - connected. If local codes permit, the
transformer primary leads can be connected at the
line- - side terminals on the unit- - mounted non- - fused
disconnect switch; this will provide service power to the
unit when the unit disconnect switch is open. See Fig. 36.
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
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

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), 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
