Initial Operation
WARNING
Take precaution while operating the filter as the filter may enter a CLEANING
mode automatically, without prior warning.
1. Gradually open the inlet valve (make sure that the outlet valve, if installed, is open).
2. Check the filter assembly and its connections for leaks.
3. Perform a CLEANING cycle by pressing the MANUAL FLUSH switches at the control panel.
4. Verify that the hydraulic CLEANING valves close after 5 CLEANING cycles and CLEANING
5. Perform a CLEANING cycle by disconnecting the high-pressure tube from the differential
pressure indicator (closing of the electrical circuit) – re-connect it after 2 CLEANING cycles.
6. Verify that the normal hydraulic CLEANING valve keeps on CLEANING as long as the
△P differential pressure indicator contacts are closed.
7. Perform an emergency CLEANING cycle by disconnecting the high-pressure tube from
the differential pressure indicator (closing of the electrical circuit – emergency CLEANING
9. When the filter is clean, verify that the differential pressure between inlet and outlet does
not exceed 0.1 bar.
10. Set the appropriate differential pressure for CLEANING at the △P differential pressure
indicator to 0.5 bar (7 psi).
11. Verify that the outlet pressure indicator reads differential pressure of at list 0.5 bar
between the filter outlet and the CLEANING chamber.

6. Verify that the normal hydraulic CLEANING valve keeps on CLEANING as long as the
△P differential pressure indicator contacts are closed.
7. Perform an emergency CLEANING cycle by disconnecting the high-pressure tube from
the differential pressure indicator (closing of the electrical circuit – emergency CLEANING
will start after 5 CLEANING cycles of normal CLEANING) re-connect it after 9 CLEANING
cycles Verify that the hydraulic CLEANING valves close at the end of the CLEANING cycle.
8. Verify that the spiral guide performed a full travel.
9. When the filter is clean, verify that the differential pressure between inlet and outlet does
not exceed 0.1 bar.
10. Set the appropriate differential pressure for CLEANING at the △P differential pressure
indicator to 0.5 bar (7 psi).
11. Verify that the outlet pressure indicator reads differential pressure of at list 0.5 bar
between the filter outlet and the CLEANING chamber.
