Installation
1.
Place the filter on an accessible flat surface and in the correct flow direction.
2.
Position the inlet and outlet manifolds, fixing the flanges with their corresponding
gaskets.
3.
Check that the drain outlet is directed to the desired area.
4.
Check that the unions are tight, turn on the water supply and verify that there is no leak.
5.
Filtering. Open the water flow at the recommended flow rate and at a working pressure
between 2.5-10 kg/cm².
6.
Cleaning. When the pressure gauge indicates a pressure difference equal to or greater
than 0,3 kg/cm², the automatic filter cleaning will begin, without interrupting the water
filtering process. The cleaning cycle leaves the factory with a duration of 30 seconds, it
must be adjusted during installation as it depends on the working pressure. For the
cleaning to be automatic, the key mus
t be in the “AUTO” position.
* Note: Place a check valve at the outlet of the filter, to avoid reverse flows and internal breaks
in the filter.

Operation
Mesh filtering consists of the physical separation between water and the substances that are
suspended in it. Water flows from the inside of the filter cartridge to the outside, causing dirt to
accumulate on the inside of the filter cartridge.
When the mesh filter becomes clogged, it produces a pressure difference between the inlet and
outlet manifolds. The automatic cleaning cycle starts when it reaches a pressure difference of
0.3 kg/cm². To check that the cleaning cycle is correct, it can be started manually by placing the
key in the ''OPEN'' position.
Cleaning process. As soon as a pressure difference of 0,3 is reached or when 24 hours of
operation have elapsed, the programmer sends the cleaning activation signal. The signal is sent
to the solenoid. The solenoid triggers the hydraulic control system, opens the flushing valve, and
communicates the hydraulic cylinder chamber with atmospheric pressure. This has two effects:
7.
The water flows through the nozzles arranged in the scanner and it is expelled through
the turbine. As a result, the water carries the dirt off the screen and in turn causes the
scanner to rotate. That is, the mesh is cleaned around the entire circumference of the
cartridge by the pressure difference.
8.
The expulsion of the water from the cylinder is carried out in a controlled way thanks to
a hydraulic calibrated orifice. The advance of the scanner and the nozzles is regulated
by this component, so check that the correct calibrated orifice is installed according to
the working pressure of the filter.
