AIR FILTER: INSTALLATION AND REMOVAL OF FILTER ELEMENTS
CLEANING FILTER INSERTS AND CHANGING SAFETY FILTER
AIR FILTER DESIGN
The air filter consists of the air filter housing with cover and dust
extractor valve, the filter insert and the safety filter.
WHEN IS MAINTENANCE NECESSARY?
If the control light (1) for the air filter on the maintenance control
panel starts to flash, the air filter insert is dirty. The air filter insert
must be cleaned or replaced.
The condition of the filter insert should be checked from time to
time, independent from the display on the control light. A damaged
or deformed filter insert must be exchanged immediately.
If the safety filter is dirty, the filter insert is damaged. In this case,
filter insert and safety filter have to be immediately replaced.
