How to Install the Unit
1 
To prevent vibration and noise, make sure the 
unit is installed securely and firmly.
2 
Install the unit out of direct sunlight.
3 
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
 • DO NOT cover or block any of the side and top 
louvers. All side louvers of the cabinet must 
remain exposed to the outside of the structure 
and unobstructed.
4 
Install the unit slightly tilted so the back is 
slightly lower than the front (about 1/4”). This 
will force condensed water to flow to the 
outside.
5 
Install the unit with the bottom between      
30”~ 60” above the floor level.
Window Requirements
 • This unit is designed for installation in standard 
double hung windows with actual opening 
widths from 22” to 36”. 
The top and bottom window sashes must open 
sufficiently to allow a clear vertical opening of 
13” from the bottom of the upper sash to the 
inside sill.

NOTE
 • All supporting parts should be secured to firm 
wood, masonry, vinyl, fiberglass, or metal.
 • This product is a window air conditioner. As 
such, a standard single-hung or double-hung 
window is required for proper installation. Non-
window installations, including using sleeves or 
wall openings, and other installation methods 
are not recommended.
Storm Window Requirements
1 
Windows that include a storm window frame 
may prevent the air conditioner from tilting 
down toward the outside to drain properly. For 
proper drainage, attach a 1” x 2” piece of wood 
to the inner sill, trimmed to a length which fits 
inside the window frame. The top of the wood 
shim must be at least 3/4” higher than the top 
of the storm window frame. Attach the wood 
securely to the sill with nails or screws.
2 
If necessary, attach another 1” x 2” wood strip 
flush against the back of the inner sill. This will 
raise the L bracket, as shown in the drawing.
