humidification). This means that it could take several hours to achieve a
measurable humidification result. If you put the air washer into operation
in a very dry environment, we recommend that you set the appliance to
continuous operation («Hygrostat» = 5 LEDs) and the speed level to 3 or 4
(«Speed») in order to effectively increase the air humidity level. Here the size
of the room and the ventilation intervals also play a role. (Also see www.

Cleaning
Prior to any maintenance, cleaning and after each use, switch off the appli-
ance and unplug the mains cable (3) from the socket.
Attention: Never submerge the appliance in water (danger of short-circuit).
• For external cleaning, rub with a damp cloth and then dry thoroughly.
• For internal cleaning, remove the water tank (5) and then pull out the wa-
ter tray (2) with the evaporator discs (8) (grab underneath the tray).
• Rinse the water tray (2) and the evaporator discs (8) with clean water once
per week, in order to wash out the particles of dirt removed from the air.
• Clean the water tray (2), evaporator discs (8) and the water tank (5) thor-
oughly every 2 weeks with a soft brush or sponge and warm water. If there
are lime scale deposits in the water tray or water tank, use a descaling
solution diluted with water (for mixture ratio, see manufacturer's instruc-
tions). Subsequently rinse the tray and tank with tap water thoroughly.
The water tray can also be cleaned in the dishwasher (at a maximum of
60 ° C). The water tank must not be put in the dishwasher.
• Descale the evaporator discs (8) approx. every 4 weeks, depending on
the water hardness level. To do so, first empty out any water remaining
in the water tray (2). Then fill the water tray with a descaling solution
(mixture ratio of solution/water according to the manufacturer's instruc-
tions) up to 2 cm below the edge of the tray (leave the evaporator discs
in the tray). Now push the water tray back into the appliance (the tank
does not have to be inserted). Activate the cleaning mode by simulta-
neously pressing the buttons «Speed» (9) and «Dimmer» (12). All white
LEDs will now flash as a sign that the cleaning mode is active. Here the
evaporator discs rotate but the fan does not run. Thus no air is blown into
the room. After 20 minutes in cleaning mode, the appliance stops and the
LEDs go out. The cleaning process may be run several times depending
on the thickness of the limescale deposits. Once the cleaning process is
finished, switch the appliance off using the On/Off switch (4). Empty the
water tray and clean it thoroughly with tap water. The evaporator discs
can also be cleaned in the dishwasher (at a maximum of 60 ° C). Please
make sure that the evaporator discs (8) are laid flat in the dishwasher.
The evaporator discs must not be inserted between the bars as this could
result in significant deformation. Lay the set evaporator discs flat in the
top tray of the dishwasher. Slight deformation after cleaning is harmless
and will not impair the functioning of the evaporator discs.
• Make sure that the air inlet and outlet are cleaned regularly to prevent
the build-up of dust. Clean the air outlet (17) with a dry brush or vacuum
cleaner. The air inlet grid (16) is fitted with an air filter which can be re-
moved and cleaned with a damp cloth. Remove the filter by pulling out the
flap at the bottom using the recessed grip.
