The Right Fit For Comfort
6. 1” x 1” Open cell foam strips are provided to prevent
outside air from entering around the chassis to the room
from the sides and top of the cabinet. Install between
wall sleeve and cooling chassis. It is imperative to
have a solid air seal between wall sleeve and chassis.
Failure to do so will result in air leakage from outdoor
to indoor causing system problems i.e. coils freezing,
short cycling, and constant running of unit. If installer is
in need of more foam than supplied in kit, consult fac-
tory (See Figure D5).
7. Once confi dent that all seals are the correct size and in
the proper location and the correct baffl es are attached
to the condenser coil in the proper orientation, slide
unit into fi nal position and tighten any tie down bolts or
screws as necessary.
