ALL UNITS
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.
Unit-mounted convenience outlets
Outlets 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 Code
Article 210, Branch Circuits, for use of convenience outlets.
Fuse on power type
The factory fuse is a Bussman “Fusetron” T-15, non-renewable
screw-in (Edison base) type plug fuse. See Fig. 29 for maximum
continuous use amp limitations.

FACTORY-OPTION THRU-BASE CONNECTIONS
(ELECTRICAL CONNECTIONS)
This service connection kit consists of a 1/2
in.
electrical bulkhead
connector and a 1 1/2 in. electrical bulkhead connector, connected
to an “L” bracket covering the embossed (raised) section of the
unit basepan in the condenser section. See Fig. 30. The 1/2 in.
bulkhead connector enables the low-voltage control wires to pass
through the basepan. The 1-1/2 in. electrical bulkhead connector
allows the high-voltage power wires to pass through the basepan.
Fig. 30 — Thru-the-Base Option, Shipping Position
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 connector 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,
aligning the holes in the gasket to the holes in the basepan.
See Fig. 31.
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.
Fig. 31 — Completing Installation of Thru-the-Base
Option
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 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.
Units Without Thru-Base Connections
1. Install power wiring conduit through side panel openings.
Install conduit between disconnect and control box.
2. Install power lines to terminal connections as shown in
Fig. 23.
