Initial Operation
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 flushing cycle by disconnecting the low pressure tube from the
differential pressure indicator (closing of the electrical circuit) – re
connect it immediately as flushing start.
4. Verify that the hydraulic flushing valve closes after 10 seconds.
5. Verify that the hydraulic piston fully extends during back flush.
6. When the filter is clean, verify that the differential pressure between
inlet and outlet does not exceed 0.1 bar.
7. Check that the differential pressure is set to 7 psi or 0.5 bar in the
controller (see appendix no 1).
8. Perform an additional flushing cycle manually by pushing the manual
bottom (M on the screen display). (See Figure 3).
