4.2. Wet stage A. – Initial flushing cycle
Important notes:
During this stage of the filter’s start-up the filter remains isolated from the process water. The supply line for the
following procedures is the flushing water supply line which is the source of clean water used for the filter’s cleaning
cycles.
Before starting wet stage A. it is very important to make sure that the filter remains isolated from the Process Water
System by verifying visually that the upstream and the downstream manual isolation valves are closed.
Consult your
Certified Installation Arrangement Drawings for these manual valves details.
The following checklist lists the actions and the order of the tasks to be done during wet stage A.

4.2.1 Connecting the filter to the flushing water source:
1. Open the Manual Isolation Valve of the clean
flushing water supply line and check the filter for
leaks.
2. Make sure that air was released from the back-
flushing pumps.
4.2.2 Index pistons positioning:
Ensure that the cassette packages are aligned with the
spry nozzles and that the index pistons are in their locked
position:
1. Check that the SW4 index piston is at SW4
switch position by verifying that the led of
switch SW4 is lighted on. This indicates that the
piston is locked at the “near to the filter
housing” side of the index cylinder.
2. Perform the same check for the SW6 index
piston and verify that the led of switch SW6 is
lighted on.
If one of the index-pistons (or both) is not locked at the
right position, switch on manually the flushing pump for
no more than 2 seconds and then recheck the magnetic
switches. You may perform this action only once! If any
of the index pistons fails to reach its locked position stop
the filter start-up process and contact your supplier.
If SW4 & SW6 leds are not ON do not proceed and
contact your supplier!!!
