12. Cleaning

Cleaning intervals depend on the build-up of
dust and dirt and cannot be determined in
advance.
Guide value: Low levels of dirt build-up
require semi-annual cleaning intervals.
1. Remove all layers of dust and dirt from the
inside of the air channel regularly.
2. Clean the fan with a dry cloth, particularly
after it has not been used for a longer
time.
Information
● Do not use aggressive cleaning agents.
● Make sure that there is no dirt in the air
channel.
