Fuse on power type
The factory fuse is a Bussman “Fusetron” T-15, non-renewable
screw-in (Edison base) type plug fuse. See Fig. 68 for maxi-
mum continuous use amp limitations.
Installing Weatherproof Cover
A weatherproof while-in-use cover for the factory-installed
convenience outlets is now required by UL standards. This
cover cannot be factory-mounted due to its depth; it must be
installed at unit installation. For shipment, the convenience
outlet is covered with a blank cover plate.
The weatherproof cover kit is shipped in the unit’s control box.
The kit includes the hinged cover, a backing plate and gasket.
DISCONNECT ALL POWER TO UNIT AND CONVE-
NIENCE OUTLET. LOCK-OUT AND TAG-OUT ALL
POWER.
Remove the blank cover plate at the convenience outlet; dis-
card the blank cover.
Loosen the two screws at the GFCI duplex outlet, until approx-
imately

-in. (13 mm) under screw heads are 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. 70. Remove two slot fillers in the bottom of the cover to
permit service tool cords to exit the cover. Check for full clos-
ing and latching.

Factory Option Thru-Base Connections
This service connection kit consists of a
1
/
2
-in. electrical bulk-
head 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. 71. The
1
/
2
-in. bulkhead connector enables the low-voltage
control wires to pass through the basepan. The 1
1
/
2
-in. electri-
cal 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 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. 72.
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 elec-
trical conduits.
Field-supplied and field-installed liquid-tight conduit connec-
tors and conduit may be attached to the connectors on the
WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal inju-
ry or death.
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 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.
