Window Requirements
All supporting parts should be secured to firm
wood, masonry, or metal.
1. This unit is designed for installation in standard double
hung windows with actual opening widths of 21" to 35".
The upper and lower sash must open sufficiently to allow
a clear vertical opening of 12" from the bottom of the
sash to the window stool.
2. If storm window presents interference, fasten a 2" wide
wood strip to the inner window sill across the full width of
the sill. The wood strip should be thick enough to raise
the height of the window sill so that the unit can be
installed without interference by the storm window frame.
See Figure. 3. Top of wood strip should be approximately
3/4" higher than the storm window frame (STORM WIN-
DOW FRAME) or wood strip (OUTDOORS) to help con-
densation to drain properly to the outside.
3. Install a second wood strip (approximately 6" long by
11/2" wide and same thickness as first strip) in the center
of the outer sill flush against the back off the inner sill.
This will raise the L bracket as shown Figure. 3.
4. If the distance between STORM WINDOW FRAME and
WOOD STRIP MOUNTED ON TOP OF INNER SILL is
more than 1", two of wood strip are not necessary.

How to Install
This air conditioner is designed with a button-down chassis so it can be easily installed in a window.
1. To prevent vibration and noise, make sure the unit is
installed securely and firmly.
2. Install the unit where the sun does not shine directly on
the unit.
3. The outside of the cabinet must extend outward for at
least 10" and there should be no obstacles, such as a
fence or wall, within 20" from the back of the cabinet
because it will prevent heat radiation of the condenser.
Restriction of outside air will greatly reduce the cooling
efficiency of the air conditioner.
CAUTION: All side louvers of the cabinet
must remain exposed on the outdside of
the structure.
4. Install the unit slanted slightly so the back is slightly
lower than the front (about 1/4"). This will force con-
densed water to the outside.
5. Install the unit with the bottom about 30"~60" above the
floor level.
