Maintenance
Clean the air conditioner and filters regularly to maximize performance and efficiency, and
prolong the unit’s life. Be sure to always unplug the air conditioner from the power outlet before
cleaning.
Air Filter Cleaning
The air filter should be checked at least once a month to see if cleaning is necessary. Trapped
particles in the filter can build up and potentially cause an accumulation of frost on the cooling
coils.
1. Push the vent handle to the “vent closed” position.
2. Grasp the filter, pull up and out.
3. Wash the filter using liquid dishwashing detergent and warm water. Rinse the filter thoroughly.
4. Gently shake excess water from the filter. Be sure the filter is thoroughly dry before replacing
it.
5. You also have the option of cleaning the filter with a vacuum.
NOTE: Winter Storage- If you plan to store the air conditioner during the winter, remove it carefully
from the window according to the installation instructions. Make sure to clean the unit thoroughly
and cover it with plastic or return it to the original carton.
Warning: Never use hot water over 113°F (45°F) to clean the air filter. Never attempt to operate
the unit without the air filter.
