Water quality maintenance
The innovative Ionic Silver Stick ® (16) uses the proven an-
tibacterial properties of silver to keep the water free from
harmful bacteria and germs. The Ionic Silver Stick releases
silver ions into the water over a period of more than one
year. It is self-renewing and needs no maintenance. Look
at picture 16 for the position of the ISS in the appliance.
Do not reach inside the nebuliser space during operation.
Switch off the unit first.
Use of fragrances
Water additives (e.g. essential oils, fragrances, water con-
ditioners etc.) must NOT be used! Even a small amount
can cause damage to the tank material. The material is not
suitable for the use of such additives. One drop is enough
to damage the tank and render the appliance unusable.
Appliances that are damaged by such additives will not be
covered by the manufacturer’s warranty.
