Non-Powered Convenience Outlet
This type requires the field installation of a general-purpose 125-v
15A circuit powered from a source elsewhere in the building. Ob-
serve 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 utili-
ty box containing the duplex receptacle.
Unit-Powered Convenience Outlet
A unit-mounted transformer is factory-installed to step down the
main power supply voltage to the unit to 115-v at the duplex re-
ceptacle. This option also includes a manual switch with fuse, lo-
cated in a utility box and mounted on a bracket behind the conve-
nience outlet; access is through the unit’s control box access panel.
See Fig. 23.
The primary leads to the convenience outlet transformer are not
factory-connected. Selection of primary power source is a custom-
er option. If local codes permit, the transformer primary leads can
be connected at the line-side terminals on the unit-mounted non-
fused disconnect or HACR breaker switch; this will provide ser-
vice power to the unit when the unit disconnect switch or HACR
switch is open. Other connection methods will result in the conve-
nience outlet circuit being de-energized when the unit disconnect
or HACR switch is open. See Fig. 27.
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.
Fuse On Power Type
The factory fuse is a Bussman
1
“Fusetron” T-15, non-renewable
screw-in (Edison base) type plug fuse.
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 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. 28). See unit nameplates for the proper fuse, HACR or
maximum over-current protection device required on the unit
with field installed accessories.
