Indicators on the device
The water level is sensed by copper electrodes and
indicated by LEDs on the control panel.
If the water supply has been depleted, and the lower
level display is reached, the device switches off auto-
matically. About 10 liters (2.5 gallons) of remaining
water stay in the device.
The [indication "Water tank empty"] on the display lights
up.
The device has a filter replacement indicator indicating
the need of a filter replacement subject to the run-time
of the pump, the water hardness and the fan. In the
best case, the filter requires replacement after 98 days,
in the worst case a replacement is required after 56
days. This is only a recommendation, the external influ-
ences (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 made. For the filter replacement see
Ä
Chapter 6.3.2 “Replacing the evaporation filter”
on page 47.
The speed of the fan is controllable in four levels. The
device has additionally an automatic function. The
speed level of the fan is indicated via the
[Indication "Fan speed level"] at the control panel.
