This air conditioner has a slide-out chassis, so
that it can be installed through an outside wall as

shims, and 10 wood screws (10-1” long minimum).
Select a wall surface that:

(including brick and stucco veneer). Working
from inside the room, nd the wall stud that is

Carefully measure and cut an opening with the
following dimensions depending on your model.
WIDTH “X” = inside model plus twice the thickness
of the framing material used.

thickness of framing material used.
Model 15K
Inside Frame Height 18 1/4” (46.4 cm)
