ELECTRICAL SUbbASE ASSEmbLY
An electrical Subbase provides a convenient location for
unit wiring to be connected to building wiring. It also
provides support for the indoor portion of the unit.
SUbbASE SELECTION
Select a subbase according to the power requirements of
the unit. See Subbase Selection chart on page 27.
SUbbASE ELECTRICAL CONNECTION
The wiring should be roughed in and the conduit con-
nected to the subbase junction box. Complete the instal-
lation by wiring the receptacle to the incoming power
supply.
Subbase Installation Notes:
1. Insert the side extension pieces into the front assem-
bly and determine the required assembly depth by
placing the assembly under the wall sleeve.
2. Determine the depth of the side extension pieces
desired and cut at the proper depth. Subbase may be
installed without the side extension pieces.
3. Insert leveling bolts into the subbase bottom flange.
Four (4) bolts are required if the side extensions are
used.
4. Place the subbase on the floor and align its center
line with the center line of the wall opening.
5. Secure the subbase to the wall sleeve with the two
retainer clips provided.
