3. – SAFETY
INSTRUCTIONS FOR THE SAFE USE OF THE FILTER
MISUSE AND IMPROPER MAINTENANCE OF THIS DEVICE CAN CAUSE
INJURY TO USERS.
TO AVOID THESE RISKS, YOU ARE STRONGLY ADVISED TO FOLLOW
THE INSTRUCTIONS BELOW.
TAKE AS MANY ACCIDENT PREVENTION MEASURES AS POSSIBLE TO
ENSURE PERSONAL AND EQUIPMENT SAFETY.
Do not touch moving parts.
Never place your hands, fingers or other body parts near the moving parts of the filter.
Do not use the filter if the guards have not been fitted.
Never use the filter if all guards have not been fitted perfectly into place (eg protective casing). If
maintenance operations require removing them, make sure the guards are securely fastened
back in their proper places before using the filter again.
Protect yourself against electric shock.
Prevent accidental contact of electrical parts of the device with metal parts thereof.
Disconnect the filter.
Disconnect the device from the power source before performing any assistance, inspection,
maintenance, cleaning, replacement or part control operations.
Release filter pressure.
Pressure off the device prior to any assistance, inspection, maintenance, cleaning, replacement
or part control operations.
Work area.
Keep work area clean and put away any potential unnecessary tools. The device can produce
sparks during operation, do not use the device in situations where varnishes, gasoline or other
combustible or explosive materials can be found.
Maintenance of the filter.
Follow the instructions in this manual, check greasing, inspect the power cable periodically and if
damaged have it repaired by qualified personnel. Check that the external appearance does not
show any visual abnormalities.

Check that screws, bolts and the cover are firmly fastened.
Regularly check they are tight.
Operate the device at nominal voltage.
Bear in mind the voltage specified in this manual and on the filter nameplate.
Never use the filter if it is defective.
If the filter makes strange noises, produces excessive vibration or appears defective, stop
operation immediately and check its functionality.
Use genuine spare parts only.
The use of non-genuine spare parts voids the warranty.
Do not modify the filter.
An unauthorized modification can decrease the performance of the device and cause serious
accidents to people who do not have adequate technical knowledge.
Disconnect and drain the device.
When the filter is not working, disconnect the device from the power and drain the filter to extend
the life of the product.

4. – DESCRIPTION OF FILTER FMA-3000
The filter consists of an outer casing which houses three distinct chambers. The first one is a
prefiltering chamber which coincides with the filter water inlet, and where the Coarse Mesh is
located, the second one is a FILTERING CHAMBER where the fine mesh is located and where
the filtering process takes place and the third one, which is acleaning chamber.
In this case the water flows outwards from inside the filtering body. Suspended solids (dirt) are
retained in the filtering element, ie in the mesh. This chamber coincides with the filtered water
outlet to the desired application: drinking water, process water, cooling water, etc.
The dirt retained gradually forms a cake on the mesh, which generates a given pressure drop.
Cleaning the filter is supported by a second chamber, the CLEANING chamber, whose outlet is
connected to the DRAIN VALVE allowing evacuation of the wash water when generating the
SELF-CLEANING process. The cleaning chamber is separated from the filtration chamber by
means of a special seal.
Finally, the SUCTION SCANNER is a vital element of this technology. This scanner occupies the
exact position that the central axis of the filtering cartridge would occupy, and is hydraulically
connected to the cleaning chamber. In turn, the SUCTION NOZZLES are arranged
perpendicularly in the zone that itoccupies in the filtration chamber, with the nylon bristles

reaching a few microns away from the mesh. The location of these nozzles in the suction scanner
has been designed to come into contact with the entire inner surface of the mesh, thanks to the
spiral movement provided to the scanner by the electric motor by combining longitudinal
displacement and rotation.

5. –FMA-3000 OPERATION
Water enters the filter through the roughing chamber, which works like a stone trap
where any coarse particles are retained.
The water flows outwards through the FINE MESH, thus producing SURFACE
MECHANICAL FILTRATION. High quality water is then obtained according to the degree
of filtration chosen for the filter mesh, which can vary from100 to 2,000 microns.
Dirt is retained and accumulated on the inner surface of the fine mesh, while causing a
gradual pressure drop between inlet and outlet of the filter. A differential pressure switch
will trigger the washing sequence when a DP equal to 0.3 bar (3 m.c.a.) is reached.
There are other possibilities to carry out the filter wash, namely wash by time, and
manual wash option.
When the differential pressure switch indicates 0.3 bar, the drain valve is commanded to
open, thus generating a differential pressure between the outside (atmospheric pressure)
and the inside of the filter (work pressure) so that a current of water at high speed is
produced, which goes through the mesh and is led to the outside through the inner hole
of the nozzles. The rotational motion is generated by this same flow passing through the
hydraulic motor located inside the cleaning chamber, while the longitudinal motion is
generated by the hydraulic piston located at the top of the filter.
The result of these joint actions is the suction effect of the nozzles onto the dirt on the
mesh, and the spiral movementof the suction scanner inside the filter.
During the self-cleaning process, which lasts 20 seconds, water continues to be filtered
and flowing into the system or application. This is due to the design of these filters, which
allows the consumption of water for washing to be MINIMAL and the duty cycle to be
CONTINUOUS.

8. – INSTALLATION INSTRUCTIONS
Take any necessary precautions to prevent bumping the filter. Lift the device by using the
anchoring points at the top.
Make sure the installation point has the minimum operating pressure.
oThe discharge pipe should be dimensioned to generate a minimum pressure loss
at a flow rate of 30 m³/h.
oIn facilities with a working pressure above 6 bar, we recommend installing a ball
valve on the discharge pipe in order to adjust the washing flow.
NOTE
MINIMUM OPERATING PRESSURE IS 2 BAR BETWEEN FILTER OUTPUT
AND DRAIN VALVE.
IN THE EVENT THAT THE DRAINAGE IS REDIRECTED, THERE MAY BE
BACKPRESSURE DUE TO PRESSURE DROP AND INCREASES IN
HEIGHT.
Install filter vertically, make sure to leave enough space to allow easy access to your
device for future treatments and to perform maintenancesafely. See section 6.
Orient the filter in the pipe according to the arrows indicating water flow direction.
It is recommended to install shutoff valves at the inlet and outlet of the filter to allow
insulation from the pipe. To avoid outages during maintenance, it is recommended to
install a bypass.
We recommend installing an anti-backflow valve at the outlet to prevent water hammer in
the filter.
The electrical wiring can only be carried out by a licensed electrician in accordance with
section 12.1
When installing the filter, prevent water from splashing onto the electrical components or
the control panel.

Diferential pressure installation ( pressure switch )
The differential pressure sensor is equipped with two maneuver tubes which must be
connected to the filter. The red tube shall be connected to the high pressure area (filter inlet)
and the black tube shall be connected to the low pressure area (filter outlet). It is advisable to
install a small 120 mesh filter before the high pressure inlet to the pressure switch.
CLEANING TIME
DEPENDING ON WORKING PRESSURE, YOU MUST SET A CLEANING
TIME ON THE PROGRAMMING UNIT (SEE ATTACHED CHART).
