Maintenance
Disconnect the unit from power supply before any
maintenance operation with the unit.
The recommended unit maintenance periodicity is 3-4 times
per year.
Maintenance of the unit means regular cleaning of the surfaces
of dust and cleaning or replacement of the filters.
To remove dust use a soft brush, cloth or a vacuum cleaner. Do
not use water, abrasive detergents, solvents, sharp objects.
The impeller blades must be cleaned once in year.
Clogged filters increase air resistance and impair the unit air
capacity. Clean the filters with a vacuum cleaner or flush under
running water. The filters must be cleaned at least 3-4 times
