in the room.

room for servicing and cleaning the Air Washer.
Filling with water (8 – 10)
Only fill the water tank with fresh, cold tap water.
Do not pressurize the water tank, e.g. by filling
it with carbonated mineral water. Do not add es-
sential oils or fragrances to the water; the plastic
material could possibly be discolored or dama-
ged. Close the screw cap completely to prevent

Operating W490
A) Switching on/off
Pressing button A switches the appliance on. Pressing it
again switches the appliance off. Button A is also used
to start the Cleaning mode. See section «Cleaning mode»
(20 – 28).
B) Setting humidity level
The appliance is fitted with a hygrostat. This measures the
relative air humidity and automatically switches the appli-
ance off when the desired value is reached. When switching
the unit on, the desired value is preset to 55%.
The desired value can be adjusted in steps of 5% by pres-
sing button B. While selecting the humidity output, the
desired value is blinking. The word DESIRED appears on
the display (F). The setting for the relative humidity ranges
from a minimum of 30% to a maximum of 70% relative
humidity or «CO» continous mode. A relative humidity
of between 40 and 60% is recommended. After a few
seconds, the display automatically changes to show the
current value (CURRENT) (F). Upon reaching the desired
relative humidity, the unit automatically switches off
(display shows DESIRED and CURRENT) (F). If the desired
relative humidity falls, the appliance automatically switches
on again.
Quick display of current relative humidity
When the unit is switched off (mains cable is connected),
the current relative humidity can be shown in the display
by briefly pressing one of the B buttons. This display auto-
matically goes out after a few seconds.
C) Changing the output level
The Air Washer can be operated on two output levels.
Press button C to select between output levels Low «L»
(night-time mode) and High «H» (Normal mode). The chosen
output level is shown in the display by symbol G.
