STORM WINDOW

REQUIREMENTS
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.
