The degree of clogging of the filter is determined by differential pres-
sure measurement. The filter display indicates the current filter status
Red = filter full
Yellow = filter status > 80%
Green = filter status < 80%.%.
When the filter is used up, an audible signal sounds
once an hour
every half hour after 36 hours
every 10 min after 54 hours
continuously after 72 hours.
The suspended matter filter and the broadband gas filter are
complementary to one another and can be replaced together as a
compact filter. The compact filter must be changed once a year in
order to ensure it is fully functional. The fine dust filter (pocket filter)
is the preliminary stage of the compact filter and therefore must be
replaced more frequently. It is sufficient to replace the pocket filter if
the red LED does not come on after restarting the unit.
Possible cause
Pipe system leaking
Filter is dirty
Turbine speed too low
Air speed through extraction-
arm is too high speed
Thermally switched off
Minimum pressure hose was
not replaced after the filter
change
Pre-filter has not been used
USB medium inserted too long
Wrong USB medium > 100
mA
Remedial measures
Reseal the pipe system
change the filter
Increase the speed setting
Reduce the air speed (reduce
air quanitity)
Leave the unit to cool down.
Switch on again after approx.
3 hours.
Reconnect the hose to the
filter
Use prefilter
Do not leave USB medium
inserted for longer than 2
minutes. Remove USB
medium and switch unit off
and on again
Remove USB medium!
