Fig. 25 — Convenience Outlet Location

Installing Weatherproof Cover

A weatherproof cover is now required by UL standards for the

factory-installed  convenience  outlets.  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. 

On  units  with  electromechanical  controls  the  weatherproof

cover kit is shipped in the unit’s control box. The kit includes

the hinged cover, a backing plate and gasket. See Fig. 26.

Disconnect All Power To Unit and Convenience Outlet.

Out and Tag-Out All Power

card the blank cover.

Loosen  the  2  screws  at  the  GFCI  duplex  outlet,  until

approximately 1/2 in. (13 mm) under screw heads is 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 2 screws until snug (do not over-tighten).

Mount the weatherproof cover to the backing plate as shown in

Fig. 26. Remove 2 slot fillers in the bottom of the cover to per

-

mit service tool cords to exit the cover. Check for full closing

and latching.

circuit powered from a source elsewhere in the building. Ob

breaker requirements and disconnect switch size and location.

Route 125

-

v power supply conductors into the bottom of the

utility box containing the duplex receptacle.

Unit-Powered Type

A  unit-mounted  transformer  is  factory-installed  to step-down

the main power supply voltage to the unit to 115-v at the du

-

plex receptacle. This option also includes a manual switch with

fuse, located in a utility box and mounted on a bracket behind

the convenience outlet; access is through the unit’s control box

access panel. See Fig. 25.

The  primary  leads  to  the  convenience  outlet  transformer  are

not factory-connected. Selection of primary power source is a

customer option. If local codes permit, the transformer primary

leads can be connected at the line-side terminals on the unit-

mounted non

-

fused disconnect; this will provide service power

to  the  unit  when  the  unit  disconnect  switch  is  open.  Other

connection methods will result in the convenience outlet circuit

being  de-energized  when  the  unit  disconnect  is  open.  See

Fig. 27. On a unit without a unit-mounted disconnect, connect

the source leads to the main terminal block (TB3).

If the convenience outlet transformer is connected to the line

side of a field disconnect, the conduit provided with the unit

must be used to protect the wires as they are routed from the

transformer to the field disconnect. The end of the conduit with

the straight connector attaches to the field disconnect. The oth

-

er end does not need to connect to the transformer; however,

the conduit must be routed so that all wiring is either in the

conduit or behind the access panel.

If the convenience outlet transformer is connected to the line

side of the factory disconnect option, route the wires through

the web bushing located on the bottom of the disconnect box.

For the load-side wiring to the factory option disconnect, route

the wires through the hole on the right side of the disconnect.

Be sure to create a drip loop at least 6 inches long.
