-in. (13 mm) under screw heads is exposed. Press the
gasket over the screw heads. Slip the backing plate over the screw
heads at the keyhole slots and align with the gasket; tighten the
two screws until snug (do not over-tighten).
Mount the weatherproof cover to the backing plate as shown in
Fig. 47. Remove two slot fillers in the bottom of the cover to per-
mit service tool cords to exit the cover. Check for full closing and
latching.

Non-unit powered type
This type requires the field installation of a general-purpose 125-v
15-A 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 type
A unit-mounted transformer is factory-installed to stepdown 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 control box and mounted on a bracket behind the conve-
nience outlet; access is through the unit’s control box access panel.
See Fig. 46.
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. 48.
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
confirmed. Observe National Electrical Code Article 210, Branch
Circuits, for use of convenience outlets. See Fig. 49.

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 Fig. 50. 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 name-
plates for the proper fuse, HACR or maximum over-current pro-
tection device required on the unit with field-installed accessories.
