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.

Select a subbase according to the power requirements of
the unit. See Subbase Selection chart on page 27.
SUBBASE ELECTRICAL CONNECTION
e 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.
