Cleaning and maintenance
CAUTION: Disconnect the mains plug prior to any cleaning or maintenance work!
• Replace the filter cartridge as soon as the filter replacement indicator (F, page 32) lights up.
The average life expectancy of the filter is approx. 1 year (depending on operation and
purification activities).
• Clean the air purifier housing with a lint-free cloth moistened with soapy water.
• Clean the control panel with a dry, lint-free cloth.
• Clean the openings for the air quality sensor (L, page 30) with a vacuum cleaner.
• Clean the air intake ducts (page 29) and the interior of the air purifier with a vacuum cleaner.
• Clean the filter cartridge's pre-filter with a vacuum cleaner. To do this, remove the filter
cartridge ("Changing the filter" page 36).
• Do not use any solvents. These could damage the housing surface, the control panel and the
air quality sensor.
• Protect the air purifier from water.
• Do not use any substances containing silicone, since this could destroy the air quality sensor.
• Do not test the effectiveness of the air quality sensor with high quantities of gas, or alcohol,
since this could destroy the air quality sensor.
