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
25.4cm(10") and there should be no obstacles, such as a
fence or wall, within 50.8cm(20") from the back of the cabi-
net because it will prevent heat radiation of the condenser.
Restriction of outside air will greatly reduce the cooling effi-
ciency of the air conditioner.
4. Install the unit slanted slightly so the back is slightly low-
er than the front [about 6.35mm(
1
/
4")]. This will force con-
densed water to the outside.
5. Install the unit with the bottom about 76.2cm(30")
~152.4cm(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 55.88cm(22") to
91.44cm(36"). The upper and lower sash must open suffi-
ciently to allow a clear vertical opening of 30.01cm(13") from
the bottom of the sash to the window stool.
2. If a storm window presents interference, fasten a 5.08cm(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 approximately
1.9cm(
3
/4") higher than the storm window frame (STORM
WINDOW FRAME) or wood strip (OUTDOORS) to help con-
densation to drain properly to the outside.
3. Install a second wood strip (approximately 15.24cm(6") long
by 3.81cm(1
1
/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 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 1.9cm(
3
/4") distance between the inner sill or the
top of the first wood strip and the outer sill.
