Storm Window Requirements
Placing the Unit Inside a Window
A storm window frame will not allow the air conditioner to tilt properly which in turn will
keep it from draining properly.
To adjust for this, attach a board or piece of wood to the sill. The board or wood piece
should have a depth of at least 1-1/2". Make sure the board or piece of wood is approxi-
mately 1/2" higher than the storm window frame. This will allow the air conditioner to
tilt enough for proper drainage. (See Fig.5).

Place the air conditioner on the sill with the bottommounting rail against its back edge.
Center the air conditioner and close the window securely behind the top mounting rail.
The air conditioner should be 3° slightly tilted to the outside area. Use a level, about
a 1/3 bubble will be the correct case slant to the outside. (See FIG.6 & FIG.7) (It is suggested
to keep a downward angle to let accumulated rain water drain out from the back side
of the unit bottom.)
