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 oor. Where the subbase is required, the
minimum distance from the oor to the sleeve must be 3 ½". 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).
