Maintaining the water trap / filter unit
To remove the water trap, just rotate the cover and unhook the filter holder body; remove the internal cup and
then replace the filter (see figure on the side).
Clean all the filter parts using water only, dry the components and reassemble the filter.
Replacing the particulate filter
If the particulate filter appears black, especially on the inner surface (see adjacent example), it has to be replaced
immediately. In this way gas flow is not obstructed.
