made by alternating window jambs. (See Alternate Window Jamb
Applications below).

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. (See “Meeting Electrical Requirements/Receptable
Wiring Needs” on Page 5).

INSTALLATION INSTRUCTIONS (CONTINUED)
To install in windows having no flanges or wood stops
on the top and side jambs, the channels and panel
frame must fit against a mounting flange (or 1/16-inch
max. thick angle) attached to the window jambs.
Figure A shows this angle installed. Figures B & C
show alternate treatments. On the sash side of the
opening, the leading corner of the inner sash becomes
the flange. You can purchase the angle strip locally.
