Important Notice

Open water inlet Nr3 at the water tank Nr2, take out the water filter Nr4 and fill in 
the water. Then close it correctly. If water is used which contains a lot of scale (more 
then german grade3) then boiled or distilled water should be used.

Water containing a lot of scale can cause scale dust around the appliance of scale 
remaining inside the appliance.
1. Scale dust can be removed by a vacuum cleaner.
2. Remains on the Transducer Nr7 or at the Bassin Nr9. In this case fill in some vinegar 

into the Bassin and dissolve the scale. Then remove the vinegar and rinse carefully. 
When the transducer is covered with scale then it cannot work correctly anymore.

3. Scale at the water filter Nr4. In this case put the water filter in some salty water (1-2 

spoons per litre water). 

4. Activate the water filter after purchasing the appliance or after a longer break. 

Refer to point 3.

5. It is best to place the humidifier above a radiator (non electrical). The mist will be 

spread in the room by the convection air of the radiator.

Usuage of the humidifier

The appliance is humidifying the air in a room.

Place the humidifier on a stable, flat and water resisting surface. To fill the water tank 
remove the nozzle at the top and take the water tank our, with the handle. Then the 
tank should be turned around and open the large lid at the bottom side of the tank.

Cold water should be filled at the bottom of tank in the tank. When the water is with 
much scale it is better to use distilled or boiled water (before inserting it should cool 
down). Never fill any chemicals, solvents or similar into the water tank. Put the plug 
of the water tank on again and it must be screwed tight. Then the tank should be 
turned around and placed on the base again. It must be taken care that the water 
tank fits good on the base. Then put the nozzles back into place.

The power plug can then be put into the socket.

Press the 

„Power“- button

. The water is then sprayed by ultrasonic in small particles 

of ca 2-5µm. If there is non or not enough water inside the device the display shows a 
small drop  .
Else in the middle of the display it shows 30% relative humidity.

By pressing the button 

„Humidity“

, it is possible to adjust the humidity from 30% to 

90% relative humidity in the surrounding of the device.
When the appliance reaches the adjusted humidity it stops working. When the humi-
dity falls bellow a lower value the appliance starts to work again automatically.

By pressing the 

„Min-Max“-button

, it is possible to adjust the output of sprayed 

water.
