Carrier WeatherMaster 48HC14 Installation Instructions Manual page 22

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-mount-
ed due 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 gas-
ket.
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 ap-
proximately 1 / -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. 40. Remove two slot fillers in the bottom of the
cover to permit service tool cords to exit the cover. Check for
full closing and latching.

HACR CIRCUIT BREAKER — The amp rating of the fac-
tory-installed HACR circuit breaker is based on the size, volt-
age, indoor motor and other electrical options of the unit as
shipped from the factory. If field-installed accessories are add-
ed 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.

bracket covering the embossed (raised) section of the unit base-
pan in the condenser section. See Fig. 42. The
connector enables the low-voltage control wires to pass
through the basepan. The 1 1 /

pan.

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 base-
pan. See Fig. 43.
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.
