Frequently Asked Questions - KSTAT12-2C Keystone
How do I install the Keystone KSTAT12-2C portable air conditioner?
Installation includes attaching the exhaust hose to the window kit, adjusting the window slider to fit your window, and securing it. Ensure the exhaust hose is not bent or kinked.
How often should I clean the air filter?
The air filter should be cleaned every two weeks or more often in dusty conditions. A dirty filter reduces cooling efficiency.
What does the 'Self-Evaporating' feature mean?
In most cooling modes, the unit self-evaporates condensate, meaning it uses collected water to cool the coils and expels it as vapor. In dehumidify mode, a drain hose may be needed.
Why is the air conditioner not cooling?
Check the air filter for dirt, ensure the exhaust hose is properly vented, and the room size does not exceed 450 sq. ft. Also verify the unit is in Cool mode and the set temperature is lower than room temperature.
Can I use an extension cord with this unit?
No, do not use an extension cord or power strip. Plug the unit directly into a standard 115V outlet rated for at least 15 amps to avoid fire hazard.
How do I set the timer?
Press the Timer button on the remote or control panel. Use the +/- to set the desired time (1-24 hours). The unit will turn on or off automatically.
What is the EER rating and why is it important?
The Energy Efficiency Ratio (EER) is 11.2, which measures cooling output per watt. A higher EER means lower energy costs. This unit is moderately efficient.
How do I drain the unit?
In normal cooling, self-evaporation eliminates most water. In dehumidify or if you see a full tank error, remove the bottom drain plug or attach a drain hose to the rear outlet.
The remote control doesn't work. What should I do?
Replace the AAA batteries (2). Ensure you are within range (20 ft) and point directly at the unit's receiver. Remove any obstructions.
Is the KSTAT12-2C a window or portable unit?
It is a portable air conditioner. It comes with a window kit for venting out exhaust through a sliding window. It sits on the floor and can be moved on casters.
