B.  Move the Angled Support Arms toward the 
exterior wall until the feet touch the wall. 
Place the level on the bracket and adjust the 
Support Arms so that it is level or tilted 1/4 
bubble downward and towards the outside. 
If exactly 1/4 bubble cannot be achieved, 
set the angled support arms to the closest 
setting so that a slight outward tilt exists.
 WARNING
Maintain control of the bracket until installation is complete.
2. Prepare the Window – Install Video Time 1:58
Lower sash must open suffi ciently to allow a clear vertical opening of 13.75 inches. Side louvers and the rear of the 
AC must have clear air space to allow enough airfl ow through the condenser for heat removal. The rear of the unit 
must be outdoors, not inside a building or garage. Find the center of your window and lightly mark with a pencil.
C.  Insert the Main Support Pin through the holes 
in the Main Support and Angled Support Arm. 
Match the hole numbers on both Main Supports 
for alignment.
If further adjustment is needed, use alternate holes 
where the Main Supports attach to the Horizontal 
Bracket.
