7.10 Display device information
7.9 Service menu
The service menu shows you the remaining service life of the filters and the operating hours of the
appliance.
7.9.1 Show the remaining filter service life
Note
You are automatically informed when the filter elements should be changed. Under
normal conditions of use, such as in offices, medical practices, schools and
environments with regular room cleaning, it is recommended to replace both the
prefilter and the HEPA filter at least every two years (if the filter replacement is not
already indicated in the LED display beforehand). An earlier end of service life (due to
improper use and increased contamination, for example) may be manifested by a
louder operating noise or unusual odor development, among other things. In these
cases, the prefilter must be replaced before the recommended service life has been
reached.
7.9.2 Confirm filter change
After replacing the filter (see chapter 8 on page 28) you can reset the filter change indicator as follows:
