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.
