On a flat surface such as a table, press the spring push pin and adjust the Left Extension Arm to the Left side of the Horizontal Bracket. Then install the Right Extension Arm into the Right side of the Horizontal Bracket. These will be adjusted in a later step.

For windows where the front of the bracket to sit on the window sill, adjust the extension arms to your window sill width. For windows where the front of the bracket will rest against the vinyl lip, these arms will be adjusted in a later step.

NOTICE

The Angled Support Arms should come installed into the Main Supports from the factory. The small tabs on the sides of the Angle Support Arms must sit on the inside bottom of the Main Support.

A. Before placing the bracket in the window, allow the Angled Support Arms to rotate down and make sure they don’t fall out of the Main support arms. Place the support bracket assembly in your window opening on the bottom windowsill. The Horizontal Bracket and Extension Arms must be located on the indoor side of your window frame.

For installations where the bracket sits on the window sill, secure the bracket to the window (reference Step E)

B. Move the Angled Support Arms toward the exterior wall until the Angled Support Feet touch the wall. Place a level on a flat area of the bracket and adjust the Angled Support Arms so the bracket is tilted downwards toward the outdoors to allow condensate to drain out. The proper angle is when the level reads 1/4 bubble (reference image for 1/4 bubble).

C. Insert the Main Support Pin through the Main Support holes and Angled Support Arm holes to secure the Angled Support Arm. Repeat for the other Angled Support Arm using the numbers stamped on the Main Support to help place both Angled Support Arms in equal locations.

D. After securing both Angled Support Arms, check the level and ensure the bracket feels secure. Minor adjustments may be needed. Once secured, insert the Cotter Pins into the Main Support Pins.

E. Center the Support Bracket with the center of the window. Note, due to the design of the Air Conditioner, the Support Bracket is biased to the left. Once centered, extend the Left and Right Extension Arms until they touch the side of the windowsill and are in front of the side window frame. Secure the bracket to the window with a screw at the end of each extension arm as shown. Holes at the end or bottom of the Extension Arms can be used to secure the Support Bracket to the window.

Care and Cleaning

Air Filter Cleaning

The air filter should be checked at least once every two weeks to see if cleaning is necessary. Trapped particles in the filter can build up and cause an accumulation of frost on the cooling coils and reduce performance. \

• Grasp the filter by the center and pull up and out

• Wash the filter using warm water. Rinse filter thoroughly.

• Gently shake excess water from the filter. Be sure the filter is thoroughly dry before replacing.

• Instead of washing, you may also vacuum the filter clean rather than washing.

NOTICE

Never use hot water over 104°F (40°C) to clean the air filter. Never attempt to operate the unit without the air filter.

Cabinet Cleaning

• Be sure to unplug the air conditioner to prevent shock or fire hazard. The cabinet and front may be dusted with an oil-free cloth or washed with a cloth dampened in a solution of warm water and mild liquid dishwashing detergent. Rinse thoroughly and wipe dry.

• Never use harsh cleansers, wax, or polish on the air conditioner.

• Be sure to wring excess water from the cloth before wiping around the controls. Excess water in or around the controls will cause damage to the air conditioner.

• Plug in air conditioner.

Winter Storage

If you plan to store the air conditioner during the winter, remove it carefully from the window according to the installation instructions. Be careful not to spill any potentially standing water from the unit’s base pan. If water is present, carefully drain it. Cover the unit with plastic or return it to the original carton.
