8.2.1 Replacing the filter holder
► Replace the filter holder regularly after 40 operating hours.
To receive an automatic request to change the filter after 40 operating hours, activate this
function in the device settings (
see "6.3.7 Switching the request for replacing filters on or
off", page 36 ). When the filter holder has been changed and the request is confirmed then
this function is reset. The request then reappears after 40 hours.
Regardless of the elapsed time, the device issues a warning or error message in case of pol-
lution.
The fine filters in the sniffer tip are built into the filter holder see "Fig. 16: The filters in the
sniffer line", page 63 .
To change the filter holder:
1 Switch the device off.
2 Unscrew the filter holder from the sniffer tip.
3 Screw a new filter holder into position.
Replacement filter holder see "10.1 Accessories and spare parts", page 67 .
