Dear customer,
We thank you for choosing the B 250 humidifier.
With this unit, you have obtained an extremely
effective evaporating humidifier and air cleaner
that offers you all the advantages of current tech-
nology. The correct humidity not only protects
your health, but also prevents damage to valuable
furnishings, fittings, and items in storage, as well
as avoiding production stoppages of moisture-
sensitive processes. The unit is totally precipita-
tion-free in its operation and, due to its low
power consumption, is also extremely kind to the
environment.
We wish you many hours of enjoyment from
your B 250 humidifier.

Inspect the delivery for completeness and make
sure the individual components (e.g., the filter)
are properly seated. Set up the unit on a level
surface and connect it to the mains power sup-
ply according to the specifications on the name-
plate. The red "Standby" light goes on and the
unit is now operational. Switch the unit on by
pressing the "Standby" button. Then open the
water reservoir cover and fill the reservoir with
clean tap water. Observe the water level indica-
tor on the operator panel when filling the unit.
Do not overfill the unit! The humidifier is now
ready to use. Adjust the unit to the desired set-
tings as described on the right.
Attention: Take care not to spill any water when
filling the unit, as this may damage electric or
electronic components or result in a short circuit.

Use the "Standby" button to switch the unit
on and off. Please note that, even when it is swit-
ched off, the unit remains under power. This is
indicated by the red "Standby" light above the but-
ton. Before working on the unit, always dis-
connect it from the mains power supply.
Fan s peed selection
The B 250 offers three-stage fan speed selec-
tion.
Stage 1 (quiet mode):
At Stage 1, the humidifier operates at a low fan
speed, making it particularly silent.
Stage 2 (high performance):
At Stage 2, the fan speed is maximised. This stage
is recommended where high or rapid humidifica-
tion is desired.
Automatic mode:
When this stage is selected, the electronic control
automatically regulates the fan speed. In other
words, if the difference between the desired and
actual humidity is very large, the fan speed is in-
creased. As the difference diminishes, the speed is
automatically reduced correspondingly.
