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

FACTORY OPTION THRU-BASE CONNECTIONS
This service connection kit consists of a
1
/
2
-in. electrical bulkhead
connector and a
3
/
4
-in. electrical bulkhead connector, connected to
an “L” bracket covering the embossed (raised) section of the unit
basepan in the condenser section (see Fig. 29 for shipping
position).
The
3
/
4
-in. bulkhead connector enables the low-voltage control
wires to pass through the basepan. The
1
/
2
-in. bulkhead connector
allows the high-voltage power wires to pass through the basepan.

1. Remove the “L” bracket assembly from the unit.
2. Remove connector plate assembly from the “L” bracket and
discard the “L” bracket, but retain the washer head screws
and the gasket (located between the “L” bracket and the con
-
nector plate assembly).
NOTE: Take care not to damage the gasket, as it is reused in the
following step.
3. Place the gasket over the embossed area in the basepan, align
-
ing the holes in the gasket to the holes in the basepan. See
Fig. 29.
4. Install the connector plate assembly to the basepan using 8 of
the washer head screws.
NOTE: If electrical connections are not going to occur at this time,
tape or otherwise cover the fittings so that moisture does not get
into the building or conduit in the interim.
Check tightness of connector lock nuts before connecting electri
-
cal 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). Remove one of the two knockouts
located on the bottom left side of the unit control box. Use this
hole for the control conduit.
