C) Operation with pre-heating
Button C is used for switching the pre-heating on and off
( symbol D lights up). As a result, the water is pre-heated to
a temperature of 80 °C before entering the nebuliser space.
It takes approx. 10 to 15 minutes for the water in the base
to warm up. The mist now leaves the nebuliser space at a
pleasant temperature of 40 °C. The advantage of this is
that the room temperature does not drop and, in addition, it
significantly improves the water quality maintenance.
D) Pre-heating Indicator
E) Empty indicator (red)
The water level is easy to see, thanks to the transparent
water tank. The appliance also alerts you when the wa-
ter tank is empty. The red empty indicator is illuminated
(symbol E). Please read the chapter «Filling the tank» for
more information. The red symbol E may stay illuminated
for some seconds with a refilled tank until the base is filled
with water.
A) On-off switch
Turning the rotary switch clockwise switches the appliance
on and at the same time regulates the mist output from
low to high.
B) Hygrostat (setting the humidity level)
The desired humidity level can be set by turning the rotary
switch clockwise. A relative humidity between 40 and 60%
is recommended. You can achieve this level by rotating the
switch until it is roughly in the vertical position. The accu-
racy of measurement is +/- 5%. The unit will switch off
when the moisture level exceeds the desired setting. The
appliance does not switch off if the switch is turned all the
way to the right. This activates the continuous operation
function.
