07. Filling

(not applicable for humidifiers with automatic
water supply)
The device is filled with water via the upper filler flap
using a watering can (only up to the max . level mark,
50 litres) . The water level is indicated by light emitting
diodes (max . 5 stages) . Both normal tap water and
softened water can be used to operate the humidifier .
m Do not use distilled water! Take care to fill
correctly, since spilt water could enter the
equipment and cause a short circuit. The
maximum temperature of the water must
not exceed 35 °C.

08. Water level indicator

The water level is sensed by copper electrodes and
is indicated by LEDs on the control panel . The device
switches off automatically if the red „Top up water"
LED comes on . A small quantity of water always re-
mains in the tank (approx . 15 litres) . It is advisable
to regularly (approx . every 3-4 weeks) drain off the
residual water depending on the degree of soiling
EN
and calcium (lime) content . The opportunity should be
taken to clean the water tank with a sponge or a wet
vacuum cleaner . The electrode rods require occasion-
al cleaning to ensure they do not indicate incorrect
values or cause the humidifier to shut down owing to
calcification of the voltage electrodes . Distilled water
must not be used because it leads to malfunctions in
the water level indicator .

09. Filter change indicator

The B 500 atmospheric humidifier has a filter change
indicator . The frequency with which the filter needs to
be changed depends on the length of time for which
the pump runs, the hardness of the water, and the
fan . Under the best circumtstances it will have to be
changed after 98 days, in the worst after 56 days, but
this is only a recommendation; the situation can be
affected one way or the other by such external factors
as air pollution or the hardness of the water . In any
case it is advisable to make regular visual checks of
the filter Please see the section on „Changing the fil-
ter" for detailed instructions . When you have changed
the filter you have to reset the indicator manually to
its initial position . Please proceed as described in the
section on „Menu programming" to Menu 33, where
you can reset the filter change indicator at any time to
its initial position of 98 days .
Filter change
Depending on the operating time of the humidifier,
the special filter is used up during the course of time
as a result of mineral deposits in the water and dust
deposits in the air (every 8-16 weeks depending on
the water hardness, dust accumulation and operating
time) . The filter should not be washed as this reduces
the evaporation capacity of the device . All humidifi-
