When you active
the ‘Filter Monitoring’, the counting of the usage days
(
indicated with ‘Update Time’
)
starts. The maximum usage time for the Prefilter is 180 days, while for the Hepa Filter is 360 days.
When the usage time exceeds these values, the warning icons appear in the ‘Homepage’ and in the
‘Overview’
: icon A in Figure 22 for HEPA filter, icon B in Figure 23 for Prefilter.
If you press on the Prefilter or the HEPA icon (see Figure 24 a and Figure 25 a), the warning shown in
Figure 24 b and Figure 25 b will appear. These warning messages and icons allow you to remember that you should
replace one or both the filters in order to avoid contaminations of the samples. See paragraph 11.3 for the Filters
Replacement.
