*If more than one accessory is to be installed, use the
maximum dimension. If the wall thickness is more than
133/4'' (35 cm) - (A + 1/4"[6.4 mm]), a sleeve extension is
required. If wall thickness is less than 6 in. (15.2 cm), a
subbase is required. See "Required Parts, Accessories and
Options."
IMPORTANT: Do not allow any tilt toward the inside of the
building. This could result in condensate dripping into the inside
of the room.

Position the wall sleeve so that it is level or tilts slightly toward
the outside of the building to facilitate condensate drainage.
Level wall sleeve side to side.
NOTE: Do not drill any holes in the bottom of the wall sleeve,
unless required by the installation of the drain kit.
Drill two 3/16in. holes through each side of the sleeve, drilling
only through the wall sleeve and not into the wall. Locate one
hole approximately 4 in. (10.2 cm) from the top and another
hole 4 in. (10.2 cm) from the bottom of the sleeve where it will
attach to the wall.
If the wall construction is wood, screw the 4 #10 x 1 in. wood
screws (provided) through the holes in the sides of the wall
sleeve. If the wall construction is not wood, obtain and use
#10 or larger fasteners suitable for the particular type of wall
construction.
IMPORTANT: When sealing the sleeve on the outside of the
building, do not let the sealant block the 2 condensate drain
holes or the 4 overflow slots at the bottom flange of the
sleeve.
Apply silicone sealant around the wall sleeve where it projects
through the inside and outside wall surfaces.
Apply silicone sealant to the screw heads.
If the chassis and outdoor grille are to be installed later, leave
the weatherboard and center support in place. Otherwise,
remove them and proceed with installing the outdoor grille.
After installing the outdoor grille, replace the weatherboard
and center support.
NOTE: Do not dispose of the weatherboard and center
support until the chassis installation is complete.
