Cleaning, maintenance and de-
scaling
You must unplug the appliance prior to cleaning,
maintenance, de-scaling or rinsing. Prior to cleaning
and maintenance, always wait until the appliance has
completely cooled down. Never hold the appliance
under running water or never immerse in water.
Single components are not dishwasher-proof!
Cleaning
As already known, the evaporation system only deli-
vers clean water steam in the room air, and the non-
wanted residues in the air like e.g. chalk, mineral
salts etc. remain in the appliance. Therefore, also for
reasons of hygiene, you should pour out the remai-
ning water every 8 days and rinse the appliance with
fresh water. Thereby, please pay attention that the
electric parts do not come in contact with water.
Moreover, we recommend you to rinse the water con-
tainer thoroughly with clear water prior to every re-filling.
Once a week, put some detergent into water contai-
ner, fill it with warm water and clean it thoroughly. Lid
(7), cover (5), steam outlet top (6) as well as the
clasp (9) should also be cleaned with tap water and
some detergent. Thereby please pay attention not to
damage the seal on the clasp (9).

Maintenance

D Above the hot-water chamber (10) there is a chalk
filter (11). This one serves a purpose to avoid that the
chalk contented in water deposits itself in the hot-
water chamber.
Wash this filter regularly with clear water, however at
least once a week.
Persistent lime deposits can be removed by putting
the filter into a weak de-scaling solution.
It is recommended to replace the chalk filter at least
after one humidification season.
E On the backside of the appliance there is an air fil-
ter (12). From time to time, rinse it also under clear
water.
In order to remove it, press slightly on the clip.
De-scaling
In order to get the maximum steam performance, and
also in order to prevent the damage on appliance,
your air humidifier has to be de-scaled regularly. You
can determine the calcifying degree by yourself.
Remove the lid (7), the water container (4) and the
coverage (5).
When the whole surface of the hot-water chamber
(10) is covered with a layer of chalk, you have to de-
scale the appliance at the latest.
For this, use a standard de-scaling agent according
to the user instructions of the manufacturer.
We recommend the use of durgol
highly efficient and yet gentle.
Observe the following steps:
• Unplug the appliance and let it cool down completely.
• Remove the lid (7), water container (4), coverage
(5) and chalk filter (11).
• First rinse the appliance thoroughly.
• Afterwards, fill the hot-water chamber (10) with the
de-scaling solution up to the edge.
• Let it react as long as all the chalk deposits dissol-
ved completely. After some time, you should swivel
the appliance a bit in order to mix the solution. In
case of persistent calcification it might be neces-
sary to renew the de-scaling solution.
• After the end of the de-scaling procedure, empty
the appliance and rinse it thoroughly with clear tap
water. Re-assemble the appliance in reversed
sequence.
• Attention! For removing the lime deposits, never
