Tools Needed

How to Install the Unit

To prevent vibration and noise, make sure the unit is installed securely and firmly.
Install the unit where the sunlight dose not shine directly on the unit.
The outside of the cabinet must extend outward for at least 12″ 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.

CAUTION

All side louvers of the cabinet must remain exposed to the outside of the structure.

4 Install the unit slightly tilted so the back is slightly lower than the front (about 1/2″). 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 27″ to 39″. The top and bottom window sashes must open 16″ from the bottom of the upper sash to the inside sill.
The height offset between the inside sill and outside sill must be less than 1 ¼”.

NOTE

All supporting parts should be secured to firm wood, masonry, or metal

Clearance

Proper clearance enhances the cooling efficiency of the product.

If a 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 drawing.) The top of the wood strip on the inside sill should be approximately ¾” higher than the storm window frame or wood strip on the outside sill to help condensation to drain properly to the outside.
If necessary, install a second wood strip (same thickness as first strip) across the full width of the outer sill, flush against the back of the inner sill.
