Frequently Asked Questions - KSTAW12CE Keystone

What is the cooling capacity of the Keystone KSTAW12CE?

The Keystone KSTAW12CE is a 12,000 BTU/h window air conditioner, suitable for cooling rooms up to approximately 550 square feet.

What window size is required for installation?

The air conditioner requires a standard double hung window with an opening width between 23 and 36 inches (584-914 mm) and a minimum vertical opening of 13 inches (330 mm).

Does the unit require a dedicated electrical outlet?

It is recommended to plug the unit into a dedicated 115V/60Hz grounded outlet. Do not use an extension cord. The power cord has a three-prong grounded plug; never cut or remove the ground prong.

How should the air conditioner be tilted for proper drainage?

The unit must be tilted downward toward the outside by about 3/4 to 1-1/8 inches (depending on model) to ensure proper condensate drainage. This tilt is achieved by the offset top rail and side panels.

Can I install this air conditioner if I have storm windows?

If a storm window blocks the installation, you may need to add wood blocking to raise the unit or remove the storm window. Ensure drain holes in the storm window are not sealed to allow water drainage.

How do I clean or maintain the air filter?

The filter should be checked every two weeks. Remove the front grille, take out the filter, and wash it with warm water and mild detergent. Allow to dry completely before reinstalling.

What should I do if the air conditioner freezes up?

Ice buildup can occur due to restricted airflow or low outdoor temperatures. Turn the unit off and let the ice melt. Clean or replace the filter, and ensure the room temperature is above 60°F (16°C) when using cooling mode.

How do I remove the air conditioner at the end of summer?

Turn off and unplug the unit. Remove the sash lock and screws. Slide side panels inward, then carefully lift the unit out of the window. Store the unit and all parts in the original carton in a dry place.

What is the R1 hardware and how do I install it?

R1 hardware is an insulation panel for Energy Star models that reduces air leaks. Measure the inner width of the side curtain, cut the panel 1/8 inch shorter, and slide it into the curtain with the patterned side facing indoors. Repeat on the other side.

Why does water drip from the overflow drain hole?

If water drips from the overflow drain during normal operation, the unit is not tilted enough toward the outside. Adjust the slope so the rear is lower than the front by the recommended height difference.
