SELECT WALL LOCATION
This unit has a slide-out chassis, so that it can be installed through an outside wall as specified below.
Maximum wall thickness:
WA-1511S and WA-1811S = 10”
WA-2211S and WA-2511S = 12”
IMPORTANT: Side louvers must never be blocked.
NOTE: All parts needed for Through-the-Wall Installation are provided, for the exception of: wood frame, shims,
and 10 wood screws (#10-1” long minimum).
Select a wall surface that:

3. Is near existing electrical outlets, or where an outlet will be installed.
4. Faces the area that needs to be cooled without any obstructions.

opening with the following dimensions depending on your model:
WIDTH “X” = inside model width plus twice the thickness of framing material used.
HEIGHT “Y” = inside model height plus twice the thickness of framing material used.
WA-1511S / WA-1811S
