This facilitates circulation and it is advantageous
if the heat source (convector or similar) is located
nearby. Avoid subjecting the humidifier to the effects
of outside temperatures in excess of + 70°C.
Location
Power consumption
The humidifier is connected to a 230V AC, 50 Hz
socket outlet. The power consumption rating is max.
300 VA. It is advisable to protect the electrical
supply line with a 10 Amp fuse. For safety reasons,
the power plug must be disconnected when carrying
out all work on the humidifier.

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 filter” 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 indicator
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 humidifiers
are equipped with a BIO filter (Order No. 1603) as standard (high evaporation capacity).
Foam filters (Order No. 1601) are also still available. In addition, we also offer a special activated
charcoal cleaning filter in a 2-pack (Order No. 1605).
Filter change
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 remains 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 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 occasional cleaning to
ensure they do not indicate incorrect values or
cause the humidifier to shut down owing to
calcification of the voltage electrodes.
Water Level Indicator
(not applicable for humidifiers with automatic water supply)
Filling
Electrode rods
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 (no distilled water) can be used to operate the humidifier. Take care to fill correctly, since
spilt water could enter the equipment and cause a short circuit.
no
Distilled water must not be used because it leads to malfunctions in the water level indicator.

In the event of a defect in the control panel it may be necessary to replace it completely.
Please proceed as follows.
1) Raise the upper part of the housing.
2) Loosen the four screws on the corners of the control panel and take the panel out.
3) Unplug the plugs (n, o, X9) from the circuit board and if necessary also unplug the plugs 3-5.
4) Use a small screwdriver to loosen the screws of the central power connection XI and pull the cable out
of the clamp.
5) Loosen any other connections (X3, X2)
6) You can now pull out the circuit board completely.
7) Now attach the individual connection to the new circuit board in the reverse order. Note the numbers on
the plugs and the circuit board when making the plug-in connections.
8) Insert the control panel back into the shaft and fasten it with the four screws
9) Now replace the upper part of the housing back onto the B 500.
Changing the control panel
Filter change
Fit new filter in reverse order, secure clips and
make sure that the filter rests within the bottom
U-shaped rail over the entire length of the water
distribution.
Before doing any work on the appliance, always make sure it is unplugged from the wall socket!
Note!
Particular care must be taken to ensure the two
side clips are fitted correctly otherwise the filter
may make contact with the upper section of the
housing, thus causing leaks.

Starting up
Carefully loosen the underneath of the housing, e.g.
with a screwdriver, take the battery out, and remo-
ve the transport protective disc. Replace the
battery (Lithium 3.6V). -> Make sure the poles
(+/-) are the right way round because the
battery will discharge instantly if they are
the wrong way round. Press the small black test
knob nto check the transmission function (the
green test diode oshould light up). Please attach
it to a dry, well ventilated place such as a ceiling
or a wall and make quite sure it is not exposed to
any direct sunlight.
(This work should be carried out by an authorised
dealer.) For calibration you need a comparative con-
stant to which you can align your radio sensor. This
can be a measuring instrument, an air-conditioned
room, or another air humidifier.

Carefully raise the cover of the radio sensor
with a small screwdriver and remove it.
Turn the rotating knob pcarefully with
a screwdriver.
Place the sensor next to the comparative
constant and compare readings.
(Do not hold it in your hand as the moisture in
your hand can give a false reading.)
If the required reading has been attained, close
the cover of the sensor again. If not, repeat
Steps 2 and 3. The sensor can be set to an
accuracy of ±5 percent.

The fan can be set by the remote control unit at any of five speeds (4 set speeds and one automatic func-
tion). The required speed can be set with the Fan button (see above) on the remote-control unit. When the
Fan button is pressed the bar indicator starts to flash. Pressing the + or the – side increases or decreases
the fan output.
The automatic function enables the appliance to control its own speed depending on the output required. It
does this by measuring the changes in atmospheric humidity and increasing or decreasing the fan speed
accordingly.
To activate the automatic fan, press the "-” side of the Fan button and hold it down until the last bar has
disappeared from the indicator and the red diode with the fan symbol has gone out. To deactivate it, simply
increase the fan speed with the Fan button until the red diode comes on again.

Coding the sensor
These appliances are coded in the factory, but if
two or more are used in direct proximity to one
another (i.e. less than 100 metres apart) a
different coding may be necessary
You have the option here of controlling a number of
appliances in one room from one sensor, with all of
them identically coded to the one sensor, or of
operating each one independently, each with a
separate sensor and different codings.
Please proceed as follows.
For each slide control there are only two positions:
"ON”= up and "0FF” = down, which give 16 poss-
ible combinations. Please note: each appliance and
its radio sensor (a + b) must have the same coding.

"Waterfresh"
The immersion pump can be removed from the
centre plate by turning it in the direction indicated
by the arrow. Take particular care when installing
the pump to ensure that the plug connection as
well as the pump hoses and the Y-piece, or on
devices with UV-technology the connection hoses
to the V4 A-pipe, are firmly fitted.
Water Pump
The water additive "Waterfresh" is particularly sui-
table for all humidifiers that operate in accordance
with the evaporation principle. It prevents the
formation of algae and reduces lime deposits in
the device. The water additive is not expelled into
the room air and is completely safe when used as
instructed.
The additive "Waterfresh" is available in a 1 litre
bottle (Order No. 9020) or 5 litre canister (Order
No. 9022) together with a measuring cup.
Take particular care when using
the water additive to follow the
dosage instructions exactly
(25 ml to 10 litres of water).
Too much additive can
cause foaming resulting in
damage to the electronic
components.
The residual water tank
with concentrated water
additive should be drained
off regularly.
The device should be cleaned of calcium (lime) deposits and soiling every 3-4 months. For this purpose, the
upper section of the housing is detached, the filter removed and the centre plate cleaned. A commercially
available cleaning agent can be used for this purpose. All traces of the cleaning agent must be removed
(rinse thoroughly with clean water).
Do not use benzene or other solvents
that attack plastic.
The humidifier should be cleaned thoroughly once
a year. (Preferably by our maintenance service.)
Use commercially available limescale remover
(decalcifying agent) to remove lime residue.
Then rinse thoroughly with clean water.
The water distributor is open at the top, easily
accessible and should be cleaned of any residue.
If blocked, the drain holes in the water distributor
can be cleaned with a knitting needle or similar. While cleaning, check to ensure there are no sludge
deposits in the pump hoses. If necessary, they should be cleaned with a narrow bottle brush or they should
be replaced.
Should the equipment remain out of service for longer periods, the residual water is to be emptied out,
the filter is to be removed and cleaning is to be carried out.
