Brune B 300 Electronic Manuel D'instruction page 15

Hygienic operation
When operating with clean fresh drinking water and maintained as instructed in this manual, the device must be used safely for humidifi-
cation in private households. Drinking water, however, contains bacteria and microorganisms. In order to ensure the hygienic and proper
operation of the humidifier, regular water exchange and regular cleaning is essential. Failure to do so may cause health problems. Therefore,
always follow the cleaning instructions and keep your device clean and fresh.
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
condition air quality). For this procedure, the casing is opened as in picture (see also chapter on „opening the casing" (page 13). The cleaning
can be accomplished 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 evaporation filter is to be decreased (see
the chapter on Changing Evaporation Filter (page 14). Additionally, the unit should be cleaned. A basic cleaning should take place annually
(possibly by our maintenance service).
Adjusting the humidity indicator
An authorized specialist should perform the adjustment. The Humidifier B 300 offers the possibility 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" (page 13)
• with a small screwdriver, carefully turn the adjustment pot (potentiometer). It is located underneath the circuit board and is accessi-
ble 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 potentio-
meter.
• Close casing after adjustment.
Maintenance intervals
The following listed maintenance works should be performed in the indicated time intervals. For all maintenance or repair, always pull the
power supply plug or ensure that the power supply is disconnected!
