7� Cleaning
Note
Before cleaning the device, ensure that the device is disconnected from the
power supply and that there is no water left in the water tank. Regular cleaning
is a prerequisite for hygienic and fault-free operation. The aroma diuser can be
dismantled for cleaning easily and without tools.
•
Clean the device after every use using a soft, slightly damp cloth to remove de-
posits (e.g. limescale), paying particular attention to the cover and the inside of
the water tank. Never use abrasive, corrosive or solvent-based cleaning products.
