Maintenance and care
Preventive maintenance
Preventive maintenance is necessary at regular intervals if the unit is to operate efficiently
and optimally without unintended downtime and to ensure the expected service life of at
least 10 years.
It is important to notice that intervals between filter maintenance can vary according to the
specific 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.
Maintenance must at minimum be carried out as shown here:
