Installation instructions for "WSC" sleeve

Wall preparation

STEP 1 The wall opening required for a "WSC" SLEEVE is 17 1/4" high by 27 1/4" wide.
STEP 2 LINTELS must be used in opening of brick veneer and masonry walls to support the material above the
"WSC" SLEEVE. The following considerations should also be given:
A. Adjustable SUBBASE (SB) or other unit support must be provided for panel wall type
construction and for walls less than 8" thick.
B. A minimum distance of 1" must be allowed on all sides of the unit to adjacent wall and fl oor.
Where the subbase is required, the minimum distance from the fl oor to the sleeve must be 3 1/2".
To minimize chances of short cycling of the compressor, the minimum clearance between the
ceiling and the top of the unit should be 24". (See Figure 8).
