Fronius IG 400 - Cleaning the Air Filter; General Information

46
The frequency with which the air filter must be cleaned depends on the air quality at the
installation site.
Important! If cooling air has to be drawn in from outside the installation area, we recom-
mend the „air supply“ option. This applies equally to IP 20 and IP 43.
