A) On / Off
Press Button (A) to turn the air humidifier on and off.
B) Hygrostat / Set humidity
Set the desired humidity in % by pressing Button (B). We
recommend a relative humidity of between 40% and 60%.
The appliance can be regulated from 40% to 75%. If the
humidity exceeds the desired setting, the appliance turns
G itself off. The appliance does not turn itself off if it has been
E
set for continuous operation.
The desired value is shown while you are making
the selection. After a few seconds, the display auto-
I
A
matically switches to the current value.

C) Timer
A 1 You can use Button (C) to determine the operating
time – it can be regulated between 1 and 6 hours or for
continuous operation. Symbol G indicates the duration that
C 3
has been set (1h/2h/4h/6h/continuous operation).
D) Regulating vapour emission,
4 evaporation rate
F
You can regulate the mist emission by pressing Button (D)
several times. The display LO/ME/HI (H) indicates which of
the three levels (low/medium/high) you have chosen.
E) Operation with pre-heating
Button (E) is used to turn the pre-heating on (symbol I
appears on the display) or off. When it is on, the water is
pre-heated to 80° C before it enters the nebulizer chamber.
The mist is now at a comfortable 40° C when it is emitted
from the appliance. This is advantageous as it does not
cause the room temperature to fall; in addition, there is
substantial improvement in maintaining the purity of the
water (bacteria are killed).

F) Auto/Sleep
Pressing Button (F) activates the automatic and sleep
mode. The automatic function is switched on by pressing
once (symbol J appears on the display), which maintains
the optimal humidity depending on the temperature. It is
regulated according to the emission quantity and the preset
desired value. If the sleep function is set (symbol K appears
on the display), the desired humidity is 60%; the timer is
automatically set for 8 hours; the heating is turned on. In
addition, the emission quantity is regulated in dependency
on the difference between desired and current value.
L) Water level display
The transparent water tank makes is easy to see how much
water is in the appliance. In addition, the appliance shows
on the display (L) when water must be refilled.
Attention!
The water tank is equipped with a demineralisation
cartridge.
This cartridge has to be replaced every 2 – 3 months. If
the water is very hard, it may be necessary to replace the
cartridge earlier. White dust around the device is a sure sign
that the cartridge needs replacing. Please note white dust is
not harmful. If white residues still forms around the device
after a new cartridge has been inserted, please make sure
that the water you are using is untreated. Otherwise the
demineralisation cartridge does not work anymore. If the
water flows through a decalcification system in the building
before it is used in the humidifier, salt will precipitate around
the device.
