INSTALLATION
Ensure that the filter is suitable for the use
envisaged and that all the technical specifi-
cations have been respected.
Do not install the filter in contact with plastered
walls.
Use appropriate tools for the installation and inter-
vene on the threaded hubs.
Mount the filter so that it is conveniently placed for
any future inspections or cleaning.
Assure that the gas flow is as indicated on the
filter.
It can be installed both on horizontal and vertical
pipes; the filter position is irrelevant.
MAINTENANCE
Change the filter element if the ∆p between
inlet and outlet pressure is more than 200
mbar with respect to the value found with
the new cartridge; in any case, the filtering
element should be changed at least once
every year.
To replace the filtering element proceed as fol-
lows:
1. Interrupt the gas flow by closing the on/off
interception tap;
2. unscrew the four screws on the perimeter of
the cover and remove the body;
3. remove the filtering element and carefully
clean the filter seat
4. replace the filtering element with a new one;
5. replace the body containing the new cartridge
in the initial position and tighten the screws;
(see table of tightening torques below).
6. check that there are no gas leaks from the
filter cover and bowl.
