«Tank empty»
The water quantity is easy to see thanks to the transparent
water tank. The display on the appliance also shows when
the unit should be refilled with water. If the water level falls
below the minimum quantity, the appliance automatically
switches off. A red blinking symbol (H) appears on the
display. When water is added, symbol H goes out and the
appliance continues operating.
Warning: When lifting the upper part off the base, the ap-
pliance also switches off. In this case, the red blinking H
symbol will also appear on the display. Only when the upper
part is replaced on the base does symbol H go out and the
appliance continues operating.

Cleaning the Air Washer (18 – 19)
• Regular cleaning is essential for hygienic, fault-free
operation, despite the Cleaning mode.
• Recommended cleaning intervals depend on air
and water quality as well as operating time.
• The Air Washer can easily be taken apart for
cleaning without tools.
The Air Washer must be emptied completely and
cleaned if the unit filled with water has not been
in operation for longer than a week.
Remove the ISS from the bottom base before
cleaning (20).
Only use CalcOff for decalcification and cleaning
of the product. Damage that is caused by the
use of other cleaning agents is not covered by
the warranty.
Cleaning mode (20 – 28)
Cleaning mode enables simple cleaning and decalcification
of the humidifier discs and the water tank.
Humidification does not take place when the appliance is in
Cleaning mode. The fan remains deactivated and only the
humidifier discs rotate.
Before switching the appliance to Cleaning mode, the water
base must be filled with hot water and the decalcification
agent CalcOff (21). Pressing and holding button A for 5
seconds switches the appliance to Cleaning mode (22).
Cleaning mode is shown in the display by flashing symbol
E (23). The value «1h» flashes in the display. Button B can be
used to change the cleaning period from 1 to 9 hours, de-
pending on the level of soiling (23). After 3 seconds without
further input, the set value is taken as the «desired value»
and flashing display F changes back to «CURRENT». The
cleaning period is now permanently displayed and swit-
ches to minutes when the time remaining falls below the
1 hour mark. The cleaning period can be changed at any
time by pressing button B. At the end of the cleaning period,
the display shows the value «0h» and cleaning symbol E
flashes faster (24). Pressing button A ends the Cleaning
mode and switches off the appliance (24). The water base
must now be emptied of the CalcOff and rinsed (25–27)
(see section «Cleaning the water tank and bottom base»).
The next time the appliance is switched on, it will operate
in normal mode.
Do not clean the soiled disc package in the dish-
washer!
Cleaning the water tank and water base –
every 2 weeks (29 – 34)
• Remove deposits from the water base with a plastic
or wooden brush and a diluted commercial dish deter-
gent.
• Put the Air Washer back together after cleaning in the
opposite order.
Cleaning the housing –
once or twice annually (35)
• First clean the housing with a damp cleaning rag and
wipe it dry; if necessary, use plastic cleaning agent.
• Wipe out the inside of the housing top assembly with
a damp cleaning rag.
