The normal service life of a main filter in the electro-
nics industry is 1500 hours.
The main filter should be changed at least once a
year in order to ensure proper gas separation.
The degree of clogging of the filter is determined by
differential pressure measurement. The filter display
indicates the current condition of the filter.
An alarm sounds and the yellow warning light
flashes: Recommended service life of filter has
expired. (see Operating time filter display/Extrac-
tion capacity filter display)
An alarm sounds and the red warning light is
lit continuously: Extraction capacity is too low.
Switch off the filter unit. Check the nozzles, tubes
and extractor arms, and clean them if necessary.
If the alarm sounds again the next time the unit is
turned on, the filter must be changed.
If no action is taken, the filter unit will cut out after
five minutes in order to avoid overheating.
When changing the main filter the filtration time
can be reset as follows:
Keep the UP/DOWN buttons pressed and, at the
same time, turn on the switch until an audible
signal sounds. Release the buttons, wait 5s and
turn the unit off. Wait another 5s and turn the unit
on. Filtration time is now reset.
