B. Choose a proper sized window.
1. 15-1/2 inches minimum width
2. 16-1/4 inches maximum width (casement windows)
3. 21-1/4 inches minimum height (with window panel
retainer)
4. 20-5/16 inches minimum height (window panel
retainer removed)
5. 39-7/16 inches maximum height
C. Choose the proper window location.
Choose a window that allows the cooled air to flow
freely and directly into room(s) you wish to cool.
Remember, it is difficult to move air around corners.
Also, choose a window that is within 6 feet of an
electrical outlet. Do not use an extension cord.
Installing Unit in a Sliding Window
1. Attach support brace to platform as shown. Use
adjustment bolt and hex flange nut to complete
assembly. Choose slot and adjustment bolt hole
locations that will create a 45 degree angle between
platform and support brace. Try assembly in the
window to determine if platform will rest properly,
and allow proper slope (3/16-inch lower on outside).
2. Measure, and lightly mark a line 8-11/16 inches
from window jamb.

Height measurement must be of a clear opening above
mounting platform. In some cases, due to a variety
of stop and track arrangements, the above dimensions
may vary slightly. If necessary, installation can be
made by alternating window jambs. (See Alternate
Window Jamb Applications.)
NOTE
If you are planning to use a siding protection board on
the outside of house, hold board in place when testing
assembly in window.
NOTE
If any sash stop protrudes more than 1 inch from the
side window jambs, the 8-11/16-inch measurement
must be increased accordingly. Screen and storm
window frames may also require adjustments to the
measurement.
