Wall Opening Requirements
When roughing in the opening for the wall sleeve,
make certain there is sufficient clearance from the
walls and floor. The wall sleeve should be positioned
a minimum of 5/8" in from the room side finished
wall to accommodate the room cabinet. A minimum
distance of 3" above the finished floor is required for
return air.
The rough opening should measure 16

". Louver frames should be
used for panel wall and thin wall applications to assure
positive anchoring to the wall (Figure 13). When a
elecrical subbase is used, the opening must start 3"
to 4" above the finished floor (including carpeting) to
match the height of the subbase selected. The subbase
is available in 3" or 4" heights and has adjustable
leveling legs that provide up to an additional 1" height.
A 3" or 4" subbase is required for 265V models and
is optional for 208/230V models.
