Brune B 300 User manual


Dear Customer,
thank you for having chosen the Humidifier B
300. Please read the operating instructions
carefully before using your new unit. We recom-
mend that you keep the instructions in a safe
place, so you may refer to them when needed.
Humidifier B300 offers a combined function – it
cleans, purifies, and humidifies the air. If only
the humidifying function is needed, the air purify-
ing function can be reduced by removing the air
filters in the suction area, which, however, does
lead to a considerable increase of the evaporati-
on performance. The function of the UV-lamp
remains in the operating mode.
We hope that you enjoy your Humidity B 300
unit.
P r i n c i p l e o f O p e r a t i o n
With this unit, you have purchased a highly effec-
tive humidifier and air purifier that offers you all
the advantages of today’s high-tech appliances.
With the proper humidity level, you are not only
protecting your health, but also prevent dama-
ging of valuable furnishings, storage goods or
prevent product loss when humidity-sensitive
production processes are involved. The unit is
operated with regular tap water and functions
completely free of condensation. The minimal
power consumption makes it an environmental
friendly device.
The Humidifier B 300 works on the principle of
natural evaporation. Thereby the humidifying and
purifying process works as described in the fol-
lowing:
The B 300 draws in the air through an air suction
opening on the side of the power cable and pas-
ses it through an air filter, which filters out the
larger dust particles and fine particles. In the
inner chamber of the humidifier, the drawn-in air
is treated with germicidal UV-C rays and than
passed on to the vapor filter. The vapor filter,
which continuously glides through the water-
bath, produces with its special structure a large
evaporation surface. This causes the air to be
cleaned one more time. After the humidification
and purification, the air is returned back into the
room. The Humidifier B300 thereby works based
on the principle of circulating air, meaning that
air in a closed room is drawn in, cleaned, and
moistened time after time until the humidity level
set has been reached. The measuring of the room
humidity thereby takes place through a humidity
sensor with a 2 meter cable. Displaying of the
room humidity and the setting of the desired
humidity takes place through the operating dis-
play. This is where you can also regulate the fan
speed.

rature in that area should not exceed 70° C.
Check the unit for any possible transportation
damages.
Check whether the delivery is complete, and
that all parts belonging to the unit are fitted
properly.
Check whether local mains voltage is the same
as the one on the identification label. The identi-
fication label is located above the power/net inlet
cable and below the fan motor. To locate the
label, you first have to remove the outer case of
the unit.
P o w e r S u p p l y
The operating display of the B 300 informs you
about the current condition of the unit. You can
read the room humidity, the set fan level, and the
water level. By using the switches + /- and AIR,
you can input the settings for your unit.
The indicator display and setting of the relative
humidity takes place in 5% increments.
Therefore, the values may deviate when using
other control devices. At 3 and 8, the display
jumps over to the next higher value (e.g. actual
humidity = 43% corresponds to =45%)
The user can, to a minor degree (+/- 5%), cali-
brate the display accuracy. Read more about this
in the Paragraph "Adjusting the humidity

The unit is equipped with two micro switches,
which, when opening the casing of the unit, swit-
ches via the control all components of the B 300
off. The disconnection via the micro switch is sig-
naled via a flashing STAND-BY indicator. Only if
the casing is completely closed, the Standby indi-
cator turns off and the air humidifier takes up
again operations.
S a f e t y o f t h e u n i t
To fill the water reservoir of the B 300, switch off
the unit as described above. The indicator in the
display helps you to determine the correct level.
Now open the lateral filler flap on the right or left
side (see fig. 1). Grab the flap at the grip above
and pull it up to the stop outward. Now you fill up
the tank to the water level as indicated on the
display, using a suitable container (e.g. watering
can or similar).
It is important that you do not spill water around
the unit or overfill the humidifier. The exiting
water can damage your furnishings or your unit.

The connection to the local water line network
must take place via a specialist, e.g. a certified
plumber. (Please comply with the regulations of
the local water supply company). A return flow
stop may be recommendable) for the connection
between unit and water pipeline, we recommend
our 1,5m long safety pressure hose (Art. No.
1754). The automatic water supply takes place
controlled by a solenoid valve (water inlet). The
unit comes standardized with the water supply
set automatically on a max. of 12 liters. This
means that after the fill level has reached 12
liters, the water supply shuts off. The controlling
of the water supply takes place via the electrode
bars of the water level indicator. For a perfect
functioning of the automatic water supply, the
electrode bars must be cleaned regularly with a
sponge to free them from lime and dirt deposits.
Accessory Water Supply (AWS)
To guarantee an optimal functioning and a long
lifetime of your B 300 unit, repair and mainten-
ance are inevitable. Depending on the conditions
in the room environment, (air and water quality),
the need for repair and maintenance can differ
(see the table maintenance intervals). The requi-
red works are described systematically in the fol-
lowing chapter.
For all works on the unit, always unplug the
humidifier or otherwise make sure that
power to the unit is off!
R e p a i r a n d M a i n t e n a n c e
To perform various maintenance works, first the
casing must be opened. Although the unit does
provide for an automatic switch-off, when the
casing is opened, to insure safety, the power
should be turned off and/or the power supply
should be pulled.
For the opening of the casing, remove the lock
clips at the upper and lower side of the humidi-
fier. Now the two halves of the casing can be pul-
led open in both arrow directions (see picture
below). Handle the casing parts with care so that
they are not damaged.
Now you can also remove the technical module. To
remove the module, lift it completely upwards. For
reinserting the technical module, slide it into the
unit along the on the bottom of the water reservoir
located gliding mechanism. Attention: check the
tension of the blue vapor filter; it can increase
during the procedure. The tension can be increased
prior to the maintenance procedure by means of the
tension pulley delivered with the unit.
The reassembling takes place in reverse order. First
slide one half of the casing on the water reservoir
up to the center of the unit. Afterwards the second
half of the casing is assembled likewise onto the tub
and pushed toward the center.

Air cleaning filter
To change the air-cleaning filter, the casing has
to be opened first (for instructions see the chap-
ter about Opening the Casing). Now the air-clea-
ning filter can be removed by hand from its posi-
tion. It is important that no residue remain.
Once the old filter is completely removed, the
new filter (Art. No. 6361) can be inserted.
Position the new filter into the same place as the
old one. It is important that filter does not inter-
fere with the rotor blades of the fan. In addition,
the filter edges should not extend outward.
Vapor Filter
For a comfortable changing of the filter, we
recommend to keep the water level as low as
possible.
First, open the casing (for instructions see the
chapter about Opening the Casing).
The old vapor filter can now be removed in that
you either open or cut the zipper. Remove the fil-
ter completely. Check the water reservoir for any
residue, and if present remove it. Dispose of the
old filter fleece into the residual waste.
Now remove the tension pulley (see illustration).
You can now start with the inserting of the new
filter (Art. No. 6360) as shown on the picture.
Close the zipper and check the tension. If it is
sufficient, you can close the casing as described
in the previous chapter. If the tension is not suf-
ficient, insert the tension pulley and repeat the
process as described above.

The change of the UV lamp should take place via
authorized technical personnel. For all work on the
unit pull the power supply plugs or ensure that the
power is disconnected! For changing the UVC lamp,
the casing is opened as described before and the
technical unit is taken out of the water tank.
Afterwards the cover of the technical unit is unscr-
ewed and the screws at the bulb socket of the UV
lamp are removed. Now the UV lamp can be pulled
out to the rear. Pull the defective lamp from its
socket and insert the new UVC lamp (Art. No.:
6210). Afterwards you push the lamp back again
into the UVC protecting glass (Art. No. 6212), Fit
the socket with the existing screws and close the
cover of the technical unit. Please also examine the
surrounding parts during the exchange of the UVC
lamp such as the UV protecting glass and the seal
(Art. No. 6213) of the UVC lamp. If you should
determine damages, the unit may be operated again
only after having exchanged the defective part.
Please dispose the defective UVC lamp in the same
manner as fluorescent tubes according to the spe-
cific local regulations of your domicile.
Adjusting the humidity indicator
An authorized specialist should perform the
adjustment. The Humidifier B 300 offers the pos-
sibility to adjust the indication of the relative
humidity within a range of +/- 5% of the actual
value, and thereby to adapt the display to other
devices or measures. Please note that there is a
microclimate in each zone of a room area and
therefore the different value displayed from one
unit to another unit or appliance, is possible and
correct. For adjustment/calibration, proceed as
follows:
● opening the casing as described in the section
" opening the casing "
● with a small screwdriver, carefully turn the
adjustment pot (potentiometer). It is located
underneath the circuit board and is accessible by
a hole in the casing at the operating panel. You
should make the adjustment in several steps, i.e.
make only a small turn at the potentiometer, and
check the result at the display. If the desired
result should not be reached yet, turn again
carefully at the potentiometer.
● Close casing after adjustment.
Cleaning of your Humidifier B 300
Every 3-4 months the unit should be cleaned
from lime arrears and contamination (dependent
on the site conditions: Water hardness dusty con-
dition air quality). For this procedure, the casing
is opened as in picture ".." (See also chapter on
Opening the Casing). The cleaning can be accom-
plished with commercial cleaning agents. Do not
use benzene or other solvents that can damage
plastics! To remove lime residues please use the
lime remover of the brand Brune (Art. No. 9016)
or a commercial lime remover. All cleaning agent
residues must be completely removed (rinse well
with clear water), since otherwise a foaming of
the cleaning agents can damage the unit.
If the unit is not operated for a longer time, the
residual water is to be emptied and the tension of
the vapor filter is to be decreased (see the chap-
ter on Changing Vapor Filter). Additionally, the
unit should be cleaned.
A basic cleaning should take place annually (pos-
sibly by our maintenance service).

Water-Fresh is best suitable for all humidifiers,
which work according to the evaporator princi-
ple. It prevents alga formation and decreases
lime deposits in the unit. Water-fresh is not
transferred to the room air, and, if appropriately
applied, does not harm your health. It is availa-
ble as 1-liter bottle (order number 9020) or 5-
liter canister (order number 9022) with a mea-
suring cup.
