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

|

5.Install the unit with the bottom about 30"~60" above the floor level.

Window Requirements
NOTICE 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 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 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.
