Preventative maintenance

Introduction
Preventative maintenance is necessary at regular intervals if the unit is to function efficiently
and optimally, in order to avoid unintended operation stoppages and to ensure the expected
lifetime of minimum 10 years .
It is important to notice, that intervals between filter maintenance can vary depending on
the specific environment, and that moving parts are wearing parts, that needs replacements
when worn down dependent on the specific environment .

tenance has been carried out as prescribed . The documentation can consist of a written log
