5 Operating the humidifier
This chapter only describes the operation of the
standard version of the humidifier. For the operation of
accessory parts, observe

Chapter 8 “Accessories”
on page 59.
5.1 Indicators on the device
The water level is detected by copper electrodes and displayed by
LEDs on the control panel.
If the water supply has been depleted, and the lower level display
is reached, the device switches off automatically. About 10 liters
(2.5 gallons) of remaining water remain in the device.
[Water level indicator] on the display lights up.
The device has a filter replacement indicator indicating the need of
a filter replacement depending on the run-time of the pump, the
water hardness and the fan. In the best-case scenario, the filter
requires replacement after 98 days; in the worst case a replace-
ment is required after 56 days. This is only a recommendation:
external influences (air pollution) can affect the recommendation
positively or negatively. Despite this indication, regular visual
inspections for signs of wear of the evaporation filter should be car-
ried out. For the filter replacement, see
Ä
Chapter 6.3.2 “Replacing
the evaporation filter” on page 41.
The speed of the fan is controllable in four levels. In addition, the
device has an automatic function. The speed level of the fan is
indicated by the [Fan speed level indicator] on the control panel.
When in automatic function, the device controls the fan speed
independently, depending on the required output. This means that
any change of air humidity is measured via the wireless sensor
system, and the fan speed is increased or decreased accordingly.
