least 10 years.
It is important to notice that intervals between lter maintenance can vary according to the
specic environment, and that moving parts are wearing parts, and will need replacement
when worn.
The factory warranty only applies if it can be documented that regular preventive main-
tenance has been carried out as prescribed. The documentation can be a written logbook
containing a company stamp or equivalent.
