If the filter is damaged irreparably it is necessary to the substitute it.
Use only original spare parts: The use of cartridge filters non original could cause a lack of
the gasket grip or damages to the other devices (filter shaker).
In order to replace the filter unscrew the several nuts that fixes the filter; reassembling it make
sure that the filters’ higher gasket fit together with the profile shaped by the cover.
Screw tight the 2 screws A and B showed in picture 3. Alternate screws while screwing them up
