INSTALLATION

Ensure that the filter is suitable for the use envisaged and that all the technical specifications have been respected.
Do not install the filter in contact with plastered walls.
Use appropriate tools for the installation and intervene 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 follows:

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.

ALL INSTALLATION, REARMING, CALIBRATION, AND MAINTENANCE OPERATIONS MUST BE CARRIED OUT SOLELY BY QUALIFIED PERSONNEL.
