CLEANING YOUR AIR CONDITIONER
Use a vacuum cleaner to remove dust accumulation from the filter. If
it is very dirty, immerse the filter in warm water and rinse it several
times, the water should never be hotter than 40°C (104°F). After
washing, leave the filter out to dry and then re-attach the intake grill
to the appliance.
