How to work the automatic
filtration station

Filtmaster uses a unique disc filtration technology. The
double face thin PP grooved discs are compressed together
in the cartridge spine to create the filtering effective sur-
face that retains the suspended solids in the dirty water.
Thiis disc cartridge is resistant to pressure and corrosion.
In the filtration process, the discs are tightly compres-
sed together thanks to the spring and the differential
pressure inside the filter. The filtration is done when the
dirty water passes through the discs to the interior of the
cartridge spin.
Check for leakages in the drainage manifold
In case that there is a leakage of water during the filtration
stage, check the sealing joints of the backwash valves.
Check inlet and outlet pressure
In case that the differential pressure is above 0,6 bar
(9 psi), activate manually the backwash of the Filtmaster
filtration station. In case that the differential pressure
remains high check for possible failures in the internal
components of the automatic disc cartridges.
Controller performance
Check that the controller timing parameters are correctly
set up. Using the controller, activate an automatic bac-
kwash cycle.
1. Make sure that the inlet and outlet HDPE manifolds
are correctly connected.
2. Check that the automatic filtration station was not da-
maged during the transport.
3. Check that filter clamps are tightly closed.
4. Power up the system.
5. Pressurize the system checking that pressure does not
exceeds 10 bar.
6. Program the controller following the instructions in
this manual.
7. Check that pressure in the outlet HDPE manifold is at
least 2,5 bar.
Filter clogged during start-up.
1. Close the downstream sustaining pressure hydraulic
valve if exists.

2. Operate manually several backwash cycles.
3. Open slowly the downstream hydraulic valve.
4. If the differential pressure remains high, check that the
flow to be filtered is not excessive. This could cause a
high head loss.
