Window AC units are specifically designed to be installed in a window. The owner's manual included with your model will provide you with the specific requirements the window should have, such as the size and type of construction.
Watch this video to learn about Window Air Conditioner Installation.
NOTE: Refer to your owner's manual for important safety information before attempting to install your air conditioner unit. Please visit our Manuals and Documents page to download a copy.
-
20 inches space.
There should be at least 20 inches of open space behind the unit, so that the heat may discharge properly. Restriction of outside air flow will greatly reduce the cooling efficiency of the air conditioner.
-
Perfect location.
Consider the location of the window you'll use. A window unit installed near a corner of the room may seem to run louder than in another location, because of the sound reflected by the nearby wall.
-
Security bracket.
Be sure to install the security bracket (also called the window locking bracket). The security bracket keeps the window securely closed against the AC's cabinet and won't allow someone from the outside to raise the window.
-
Air flow blockage.
Avoid having curtains that will be pulled into to the air conditioner's front grille. The blockage in air flow will reduce the cooling efficiency of the unit and can lead to frost accumulating on the coils.
-
Tilt backwards.
When the AC is installed, keep in mind that the unit should have a tilt towards the back (1/4 - 1/2"). If the back of the unit isn't installed slightly lower than the front the unit can leak condensed water from the front grille.
-
Drain plug.
The drain plug does not have to be installed in all cases. The air conditioner is designed to operate with about 1/2" of water in the base pan. This water is picked up and slung onto the condenser by the slinger fan to help discharge heat. This helps to improve cooling efficiency. In humid conditions it may be necessary, or preferred, to remove the plug to allow excess water to drain out.
