Weatherproof Cover Installation
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 unit nameplate and label on fac
-
tory-installed HACR for the amp rating of the HACR that was
shipped with the unit from the factory. See unit nameplates for the
proper fuse, HACR or maximum over-current protection device
required on the unit with field-installed accessories. See Fig. 48.

TRICAL CONNECTIONS)
This service connection kit consists of a

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. 49. The
1

-in.
bulkhead connector enables the low-voltage control wires to pass
through the basepan. The 1

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. 50.
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.

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 and low voltage through appro
-
priate conduits. Connect the power conduit to the internal discon
-
nect (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.
