I. 5 CLEANING THE UNIT
DANGER!
Always disconnect from the power supply before starting cleaning or maintenance work. Do not spray water onto the unit.
It is possible to clean the unit exterior. To clean it, use a soft cloth dampened with water and alcohol. Do not use hot
water, abrasive or corrosive substances, or solvents.
I. 5.1 CLEANING THE AIR FILTER
To ensure correct air suction, the filter must be cleaned at least once a month, or even more often if the unit is
installed in a very dusty environment. The filter must always be removed from the unit for cleaning purposes.
The air filter is made from acrylic fibre that can be washed in water.
