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. After 250 hours of operation, the Check Filter indicator will light up on the control panel as a

reminder.

1. Push the vent handle to the “vent closed” position.

2. Open the front panel.

3. Grasp the filter at the center, pull up and out.

4. Wash the filter using liquid dishwashing detergent and warm water. Rinse the filter thoroughly.

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

it.

6. You may also gently clean the filter with a vacuum.

7. Reinstall the filter when it is thoroughly dry.

8. Press the Check Filter button on the Control Panel to reset the Check Filter timer.

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 40°C (104°F) to clean the air filter. Never attempt to operate

the unit without the air filter.
