WINDOW REQUIREMENTS
Your air conditioner is designed
to be installed in standard
double hung windows with
minimum width and height
requirements as follows:
W
: Opening widths of 28 inches
(for 15K and 18K models) or 31
inches (25K models).
H
: Opening height of 18.5 inch-
es (for 15K and 18K models) or
19.5 inches (25K Models).
STORM WINDOW MODIFICATIONS
If you have storm windows, the exterior window frame will be slightly higher than the
windowsill, which results in an air conditioning unit that is slanted inward and may
cause water condensation to enter the room interior. Perform these modifications to
ensure proper operation of your unit. If you have a standard window, skip this step:
1. Cut a 2” thick piece of wood to the length of the interior window width.
2. Verify that the wood is level with or up to 0.5” (1cm) higher than the exterior
storm-window frame.
3. Fasten the wood with screws to the windowsill and proceed with mounting.
Exterior Wall
Board thickness
should be as required
for proper pitch and
run along the entire
window sill. Fasten
with nails or screws.
