WINDOW REQUIREMENTS

• These instructions are for a standard double-
hung window. You will need to modify them
for other types of windows.
• The air conditioner can be installed without
the accordion panels if needed to fit in a
narrow window. See the window opening
dimensions.
• All supporting parts must be secured
to firm wood, masonry or metal.
• The electrical outlet must be within reach of
the power cord.
• Follow the dimensions in the table and
illustration for your model.

STORM WINDOW REQUIREMENTS
2
A storm window frame will not allow the air
conditioner to tilt toward the outside, and will
keep it from draining properly.
To adjust for this, attach a piece of wood to
the sill.
WOOD PIECES
WIDTH: 2"
LENGTH: Long enough to fit inside the
window frame.
THICKNESS: To determine the thickness, place
a piece of wood on the sill to make it 1/2"
higher than the top of the storm window
frame or the vinyl frame.
Attach securely with nails or screws provided
by the installer.
