3. INSTALLATION

This air conditioner is designed with a button-down
chassis so it can be easily installed in a window.

3.1 SELECT THE BEST LOCATION

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 slight-
ly lower than the front (about
condensed water to the outside.
5. Install the unit with the bottom about 30"~60"
above the floor level.

3.2 HOW TO INSTALL

3.2.1 WINDOW REQUIREMENTS
NOTE: 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 22" to 36".
The upper and lower sash must open sufficiently to allow
a clear vertical opening of 13" from the bottom of the
sash to the window stool.
2.If a 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 Fig. 24. Top of the wood strip should be approxi-
mately 3/4" higher than the storm window frame (STORM
WINDOW FRAME) or wood strip (OUTDOORS) to help
condensation to drain properly to the outside.
3. Install a second wood strip (approximately 6" long by 1
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 Fig. 24.
The thickness of the second wood strip may not be the same
as the first wood strip.
The thickness of the second wood strip must be defined to
keep the 3 / inch distance between the inner sill or the top of
4
the first wood strip and the outer sill.
