a. The differential pressure indicator supplies data to the electronic control unit,
which controls the filter's self-cleaning process.
1. Set the main switch at the control panel to "0" position.
2. Close the inlet and outlet valves of the filter and verify that the filter is drained prior to service.
3. Disconnect the two control tubes from the differential pressure indicator.
4. Remove the 4 screws attaching the electric connection box.
5. Disconnect the electrical wiring from the electric terminal in the connection box.
6. Remove the two nuts located at the bottom of the electronic control unit assembly and remove
which controls the filter's self-cleaning process.

5. Disconnect the electrical wiring from the electric terminal in the connection box.
6. Remove the two nuts located at the bottom of the electronic control unit assembly and remove
the screws.
7. Pull the differential pressure indicator out of the control assembly.
8. Insert a new differential pressure indicator into the control assembly.
9. Install the two screws and nuts at the bottom of the electronic control unit assembly.
10. Connect the two control tubes to the differential pressure indicator [note that the high
pressure and the low pressure connected to the right fittings].
7. Pull the differential pressure indicator out of the control assembly.
8. Insert a new differential pressure indicator into the control assembly.
9. Install the two screws and nuts at the bottom of the electronic control unit assembly.
10. Connect the two control tubes to the differential pressure indicator [note that the high
pressure and the low pressure connected to the right fittings].
NOTE: High pressure line must be connected to the "H", low pressure pipeline must
be connected to "L". High pressure pipeline – the inlet, Low pressure pipeline – the
outlet, "H", "L" indicates the pressure indicator was "High" and "Low".
11. Connect the electrical wiring to terminals D and P on the electric terminal connection
box.
WARNING
Take precautions while operating the filter because the filter might enter a flushing
mode automatically, without prior warning.
12. Set the main switch at the control panel to "1" position.
13. Perform a flushing cycle by disconnecting the high pressure tube from the differential pressure indicator
(closing of the electrical circuit) – re-connect it immediately as flushing start.
14. Verify that the hydraulic flushing valve closes after 10 seconds.
15. Perform a flushing cycle by pressing the MANUAL FLUSH switch at the control panel.
