Location Requirements
IMPORTANT:
Observe all governing codes and
ordinances.
Check the location where air conditioner will be
installed. Proper installation is your responsibility.
Make sure you have everything necessary for
correct installation.
The location should provide:
Grounded electrical outlet within 5 ft of
where the power cord exits the air
conditioner.
NOTE:
Do not use an extension cord.
Free movement of air in room to be cooled.
A large enough opening for the air
conditioner.
Adequate wall support for weight of air
conditioner. Air conditioner weights up to
139 lbs.
NOTE:
Cabinet louvers & rear of the air
conditioner must not be obstructed. Air must be
able to pass freely through the cabinet louvers.
The rear of air conditioner must be outdoors. Not
inside a building or garage.
Window Requirements:
These instructions are for
a standard double hung
window. You will need to
modify them for other

The air conditioner can be
installed without the
accordion panel if needed
to fit in a narrow window.

Storm Window Requirements:
A storm window frame will not allow the air
conditioner to tilt properly which in turn will keep
it from draining properly. To adjust for this,
attach a board or piece of wood to the sill. The
board or wood piece should have a depth of at
least 1 1/2”. Make sure the board or piece of
wood is approximately 1/2” higher than the storm
window frame. This will allow the air conditioner
to tilt enough for proper drainage. See below.
