3. Fan maintenance (1 time per year)
Even with regular filter
maintenance, some dust may
build up on the fans, reducing
fan performance and supply
air flow.
Clean the fans with a soft
cloth or brush.
Cleaning
with
water,
abrasives, sharp objects, etc.
is not permitted in order not
to damage the impeller.
4. Maintenance of the supply air grille (2 times per year)
Leaves and other dirt can clog the supply air grille and reduce
the delivery rate. Check the condition of the supply air grille
regularly and clean it of foreign objects as necessary.
5. Maintenance of the ventilation pipes (every five years)
Even if you carry out all the recommended maintenance
regularly, some dust may get into the ventilation pipes and
thus reduce the delivery rate and volume flow.
Maintenance consists of regular cleaning or replacement of
the ventilation pipes.
