Cut the foam top window gasket to the window 
width.
Stuff the foam 
between the glass 
and the window 
to prevent air and 
insects from getting 
into the room.
NOTE: If the gasket supplied does not fit your 
window, obtain appropriate material locally to 
provide a proper installation seal.

CAUTION:  
To prevent broken glass or

Place the air conditioner on the sill with the 
bottom mounting rail against its back edge. 
Center it and close the window securely behind 
the top mounting rail. 
It should be level or slightly tilted to the outside. 
Use a level; about a 1/3 bubble will be the correct  
case slant to the outside.
Extend the left and right accordion panels to 
the vertical window sashes and attach 3 screws 
through the holes in the upper panels, as 
appropriate.
Install the frame locking brackets between the 
bottom of the accordion panel and the window 
sill. Attach with 2 screws. NOTE: To prevent the 
window sill from splitting, drive the pilot holes 
before driving the screws.
