Assemble the filter in such a way that the cover can be easily
removed for inspection or cleaning.
Ensure that the gas flow direction is that indicated on the filter.
It can be assembled both on horizontal and vertical piping.
Maintenance
Change the filter element when Δp between the pressure taps
connections exceeds 10 mbar; anyway it is recommended to
replace the filter element at least once a year.
To replace the filter element you need to:
1. cut off the gas flow by closing the cut off cock;
2. unscrew the screws and remove the cover;
3. remove the filter element and clean the filter housing
carefully;
4. replace the old filter element with a new one;
5. reassemble the filter cover ensuring that the guides
inside the cover are aligned with the filter element and
then tight the screws again;
