Water purification (optional)
An Ionic Silver Stick (17) keeps the water free of harmful
bacteria. The anti-microbial action of silver is used. The
Ionic Silver Stick releases silver ions in the water over a long
en
period (approx. one year). Look at picture 17 for the position
of the ISS in the base part of the unit. Do not touch the water
in the base during operation! Switch off the unit first. (If the
Ionic Silver Stick is not automatically in your device, you can
buy it optionally later).
Use of additives
Water additives (ethereal/essential oils, fragrances,
eucalyptus, water conditioners etc.) must not be used! Even
a small amount can cause cracks in the tank material. The
material isn't made for the use of such additives. One drop
is enough to damage the tank and as a consequence the
unit. Any use of such additives will void the manufactures
warranty.

A) On-off switch and
regulation of vapour output
Turning the lower knob clockwise switches the humidifier
on and also regulates the vapour emission from low to
D
high.
B) Hygrostat (regulating humidity level)
By turning the upper knob clockwise, you set the desired
humidity. Recommended is a relative humidity between
40% and 60%. As soon as the desired humidity is ex-
ceeded the humidifier is switched off. The appliance does
not switch off when it is set to continuous operation.
B
C) Operating with preheating
On pressing the preheating switch the water is pre-
heated to 80° C before entering the humidifier room.
So, the outlet vapour will have the pleasant temperature
of 40° C. This provides the advantage that the room tem-
perature will not fall, and additionally the water can be kept
essentially cleaner (bacteria are killed).
E) Empty display
The red LED indicates that the water tank is empty. For
more information, see the chapter «Filling with Water».
