14.3.5 Reset filter change indicator
After every filter change, the filter change indicator
must be reset in order to restart monitoring of the
period since the last filter change. The procedure
is as follows:
►
Within three seconds, select the ventila-
tion levels
I-II-III-II-I
one after the other on
the stepping switch (item 1 in Fig. 17).
The ventilation unit will beep as confirma-
tion.
►
Within three seconds, while the ventilation
unit is beeping, again select the ventilation
levels
I-II-III-II-I
one after the other on the
stepping switch (item 1 in Fig. 17).
The ventilation unit will beep three times
as confirmation. Monitoring of the filter is
restarted.
15 Cleaning
WARNING
►
Switch off the power to the ventilation unit before cleaning.
►
When cleaning, make sure that no moisture penetrates into the inside of the housing.
►
Never use a high pressure cleaner, steam cleaner or steam jet.
The ventilation unit is made of high quality plastic and requires little care.
►
Wipe the outer surfaces from time to time with a soft, damp cloth. Use a mild cleaning
agent. A commercially available plastic cleaner can be used for particularly stubborn dirt.
NOTE
►
Never use acidic, corrosive or abrasive cleaning agents.
