4 Maintenance
4.1 Maintenance
When maintaining the filter, keep in mind the following:
• On filters with manual drain valve, open the latter at regular intervals to evacuate collected
dust or liquid.
• In case an automatic drain valve or a solenoid timer drain is installed, manual draining can
be carried out by opening the valve counterclockwise to release collected condensate.
When the filter has to process air with a temperature higher than the specified maximum
temperature, the filter's lifetime will be reduced considerably!
4.2 Filter element change
The hand-tool icon on the figure indicates the items provided in a dedicated filter kit.
1. Before filter element change, check for any leakages at the bottom of the filter bowl
(connection of manual and automatic drain) during normal filter operation. If no leakage is
observed, point 6 up to 9 can be discarded.
2. Isolate the filter from the air net.
3. Depressurize the filter by turning the connection nipple of the automatic drain valve
counterclockwise or by opening the manual drain valve.
4. Unscrew the bowl.
5. Discard the filter element.
