Installation

Window Requirements
Size
This room air conditioner is designed for installation in standard double-hung windows with actual opening widths (refer to below table). The upper and lower window sash must open sufficiently to allow a clear vertical opening of height from the bottom of the upper sash to the window stool.

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, holes in walls, and other installations are not recommended.

Clearance
Proper clearance enhances the cooling efficiency of the unit.

1. 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.
2. See drawing. The top of the wood strip should be approximately 3/4"higher than the storm window frame or wood strip (Outdoors) to help condensation to drain properly to the outside.
3. Install a second wood strip (same thickness as first strip) in the center of the sill flush against the back off the inner sill. This will raise the L bracket(Type D)as shown in the drawing.
   

Preparation of Chassis

1. Insert the guide panels (Type G) into the upper and bottom guide. Fasten the curtains to the unit with 4 screws (Type A) on each side.
   Use a long screwdriver and installing the screws will be easier.
   
2. Cut the window sash seals to the proper length Peel off the backing and attach the Foam-PE (Adhesive backed) to the underside of the window sash and bottom of window frame.
   
3. Open the window and mark center line on the center of the inner sill.
   
4. Attach L bracket (Type D)
   
   1. Install the L brackets behind the inner window sill, with short side of bracket as shown. Use the 2 screws (Type A) provided.
   2. The bracket helps to hold unit securely in place. Be sure to place bracket edge flush against back of inner sill.

Unit Installation

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.

4. Cut the adhesive-backed Foam- Heatproofs to the Guide Panel size. Remove the backing from the Foam-Heatproofs and attach the Foam-Heatproofs to Guide Panel.
   Foam-Heatproof improves the cooling capability of the unit.

Maintenance and Service

Air Filter
Check the air filter at least twice a month to see if cleaning is necessary. Trapped particles in the filter can build up and block the airflow, reducing cooling capacity and causing an accumulation of frost on the evaporator. To clean the air filter:

1. Remove the air filter from the front grille by pulling forward the air filter and then up slightly.
2. Wash the filter using lukewarm water below 40ºC (104 ºF)
3. Gently shake the excess water from the filter and replace.

Cleaning The Air Conditioner
The front grille and inlet grille may be wiped with a cloth dampened in a mild detergent solution. The cabinet may be washed with mild soap or detergent and lukewarm water, then polished with liquid wax for Appliances. To ensure continued peak efficiency, the condenser coils (outside of unit) should be checked periodically and cleaned if clogged with soot or dirt from the atmosphere

Removal From Window
Turn the air conditioner off, disconnect the power cord, remove the L bracket, the screws and Support Bracket installed through the top and bottom of the guide panels, and save for reinstallation later. Close the guide panels. Keeping a firm grip on the air conditioner, raise the sash, and carefully tilt the air conditioner backward, draining any condensate. Lift the air conditioner from the window and remove the sash seal from between the windows. Be sure to drain ALL condensate from the air conditioner. If you don't, it could run out while you carry the unit, making a mess and creating a slipping hazard. This simple step will save you much cleaning and make a safer work environment.
