3.1 Cleaning the Air Filter

Clean the air filter about once a week with a neutral cleanser and leave it to dry in a shady location. Clean more regularly if the air filter gets very dirty.

If the filter gets blocked, air will not be sucked in properly, and the cooling effect will deteriorate. Failure to clean the air filter may result in equipment breakdown or malfunctions.

3.2 Cleaning panels

Clean dirt off front panel as follows.

Use a household neutral cleanser such as for dishes or vegetables. Moisten a soft cloth with the cleanser, then wipe lightly. Next,wipe three or four times with another soft cloth moisten with water. Finally, wipe off all the remaining cleanser with a soft cloth.
