8. CLEANING AND MAINTENANCE
Regular cleaning and disinfection are a prerequisite for hygienic and fault-free operation.
The level of contamination of the device depends on the water quality and how long it has been in operation. In any case,
we recommend the following cleaning intervals.

Use either a citric acid solution (30 g pure citric acid powder dissolved in 1 l water) or a vinegar solution (household vinegar
with 5% acid content mixed with water in a ratio of 1:2) as a descaling solution.
WARNING
The device must be switched off after every use and before cleaning. Pull the plug out of the mains socket.
IMPORTANT
The water tank must be cleaned and the air humidifier completely emptied if the device has not been used for 72 hours.
Note
• Clean the device using only the methods specified.
• Under no circumstances may liquid enter the base unit.
• Do not use any solvent-based cleaning products.
• Use only a mild detergent or citric acid or vinegar-based solution to perform cleaning or disinfection work.
Cleaning the ultrasound membrane with a brush, rinsing the base
Note
Empty the water from the base unit via the side rim in the direction indicated by the arrow. Ensure that no water gets inside
the device, e.g. via the fan opening.
• Clean the ultrasound membrane using the cleaning brush provided.
• Empty the water from the base unit via the side edge.
• Should dirty residue remain in the base unit, pour some clean, fresh water
into the base unit and empty it out via the side edge.
Rinsing the water tank, replacing the water
• Clean the water tank regularly, at least every three days if using daily.
• Use a mild cleaning product or a citric acid or vinegar-based solution.
• Clean the thread of the screwed plug using a soft brush.
• Half-fill the water tank with water.
• Tightly close the water tank using the screwed plug.
• Shake the water tank by rocking it back and forth several times.
• Empty out the water completely.
• Repeat the process using clean, fresh water.
Cleaning the air humidifier inside and out
• Empty the water from the base unit via the side edge.
• Wipe the air humidifier with a damp cloth inside and out. Use only a mild detergent or citric acid or vinegar-based
solution to perform cleaning work.
Descaling
Descaling the ultrasound membrane
Hard water can cause limescale to build up in the device and, especially, on the ultrasound membrane. This forms white
deposits. Descale the device regularly.
• Drop some descaling solution onto the ultrasound membrane.
• Leave it to take effect for two to five minutes.
Clean the ultrasound membrane with a brush, rinse the base.
Rinse the water tank, replace the water.
