CLEANING OF THE AIR FILTER
An obstructed air filter reduces the capacity of the air
conditioner, and increases the power consumption.
Check it monthly.
Do not use the air conditioner without the filter, since
the dust and the impurities will damage it, or require
a specialized cleaning.
For electronic conditioners, there is an indicator ( )
that warns when the filter needs to be cleaned.
After cleaning, press simultaneously for 3 seconds, the
Select button and the (-) button, and the indicator light
will turn off.
The air conditioner filter can be cleaned by vacuum or
washing.
Before starting to clean, turn
off the unit, and open
the plastic front.
Remove the filter.

Cleaning by vacuum: pass the vacuum cleaner hose
nozzle to remove the dust accumulation.
Washing: position the filter with the dirty part turned
downwards, and let the water run on it. This way, all the
dirt and impurities will be easily removed.
Install the filter with the knob downwards.
Close the plastic front.
