14. Install the sash safety bracket with a
3
/

-in. screw
provided. Pre-drill the hole with
1
/
8
-in. drill bit.
The sash safety bracket is installed on the upper
sash and is used to keep the window from open-
ing. See Fig. 10.
15. Cut the foam seal (provided) to fit the length of
the window. Insert the foam seal between the top
of the lower window sash and the window panes of
the upper window. See Fig. 11. Make sure there
is a firm fit to prevent air leakage between the
windows. This also prevents insects from entering
through the window.
16. Plug in the unit.
STORM WINDOW APPLICATIONS
If the storm window cannot be removed, a mounting
board (field-provided) may need to be added to the
window sash. The air conditioner needs to be pitched
downward to the back in order for condensate to drain
properly. The frame of the storm window (or any other
obstruction) must be at least
1
/
2
in. lower than the win-
dow sill. If the storm window frame is less than
1
/
2
in.
below the window sill, then a mounting board will
need to be added to raise the height of the window sill.
See Fig. 12. The board will need to be provided and cut
by the installer.
1. The length of wood should be a minimum of
1
1
/
2
-in. wide and should run the length of the win-
dow. The thickness of the board is dependent on
the height of the storm window frame. The board
should raise the front of the air conditioner high
enough so that the unit will be pitched downward
at least
5
/
8
-in. when the back of the unit is resting
on the storm window frame. See Fig. 12.
2. Cut the piece of wood to fit the window.
3. Install the wood piece on the window using 2 field-
provided nails or screws.
4. Drain holes or slots in storm window frame must
not be caulked or painted shut. Holes are needed
to drain rain water and condensate. Ensure that
trapped water can drain out.
