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.

4. Install the unit slanted slightly so the back is slight-

ly lower than the front (about 

1

/

4

"). This will force

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 dou-

ble 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 bot-
tom 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. 24. Top of wood
strip should be approximately 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

11/2" wide and same thickness as first strip) in the cen-
ter of the outer sill flush against the back off the inner
sill. This will raise the L bracket as shown Figure. 24.

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 neces-
sary.
