How to Install the Unit

To prevent vibration and noise, make sure the unit is installed securely and firmly.
Install the unit out of direct sunlight.
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.
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.
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 21” to 35”.
The top and bottom window sashes must open sufficiently to allow a clear vertical opening of 12” 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

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.
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.
Wood Strip Mounted

Preparation of the Chassis

Assemble two supporters with upper guide. Align holes between the upper guide and the top of the cabinet and then install it with 3 type A screws.

NOTE
- The feature may be changed according to the type of model.
Slide the Side curtain directly into the cabinet. Insert the top and bottom rails of the curtain panels into the upper and lower panel guides.

NOTE
- The feature may be changed according to the type of model.
Cut the window sash seals to the proper length. Peel off the backing and attach the adhesive-backed foam to the underside of the window sash and bottom of window frame.
Open the window and draw a center line on the center of the inner sill. Then mark lines 7.5” to the left and right of the center line.
Install the L bracket behind the inner window sill, as shown. Use the 2 type A screws provided.

NOTE

  * The bracket helps to hold unit securely in place. Be sure to place bracket edge flush against back of inner sill.

Unit Installation

CAUTION

During the following step, hold unit firmly until window sash is lowered to top channel behind side panel frames. Personal injury or property damage may result if unit falls from window.

Set the air conditioner in the window so that is centered. Place the air conditioner so that front edge of the bottom guide is against the back edge of the sill. Bring the window down so that the front edge of the upper guide is in front of the window. Make sure that air conditioner is level or tilting slightly to the outside.
Extend the guide panels to fill the window opening and use 5 type B screws to secure them to the window.

NOTE
- The feature may be changed according to the type of model.
Cut the non-adhesive foam strip to the proper length and insert it between the upper window sash and the lower window sash.
To prevent broken glass or damage to windows, on vinyl or other similarly constructed windows, attach the L bracket with a type A screw.
