Installation

“T” section

Your air conditioner is designed to install in standard double hung windows with opening widths of 24 to 36 inches
(609 mm to 914 mm) (FIG. 4A & FIG. 4B)
Lower sash must open sufficiently to allow a clear vertical opening of 13.25 inches (337 mm ). Side louvers and the rear 
of the air conditioner must have clear air space to allow enough airflow through the condenser, for heat removal. The rear 
of the unit must be outdoors, not inside a building or garage.

If the air conditioner is blocked by Storm Window, add wood as 

shown in FIG. 5, or remove storm window before air conditioner
is installed. 

If Storm Window Frame must remain, be sure the drain holes or
slots are not caulked or painted shut. Accumulated Rain Water
or Condensation must be allowed to drain out.

Top Rail and Side Panels at each side are offset to provide the proper pitch to the rear. This is 

necessary for proper condensed water utilization and drainage. If you are not using the Side Panels for any 
reason, this pitch to the rear must be maintained!
