Screen
Starting up after a long shutdown period
1. Start the system up and slowly increase pressure. Complete two or three washing cycles in a row. Check that the
maximum pressure supported by the system is not surpassed.
2. The controller has a partial counter for the number of washing cycles (depending on the model). If you set it to
zero, save the number of cycles. There are controllers which keep a total count.
3. It is recommended to change the seals and membranes or diaphragms every 14,000 cycles.
4. Clean the solenoids if the drainage microtubes marked in yellow no longer drain.
5. Disassemble and check the cartridge (follow the instructions and photographs of each filter) and possible obstruc-
tions caused by sand stuck in the screen, iron or lime deposits. Clean manually and, if necessary, with acid.
6. Exchange manometers or replace them with new ones.
7. Clean auxiliary filter of the hydraulic control circuit.
High frequency of washing or continuous washing
1. Check if the cartridge is dirty.
2. It is possible that the quality of the water has gotten worse. In that case the flow rate should be reduced, or more
filters installed.
3. High flow rate at the start of irrigation. There is a high pressure drop and the differential pressure control devices
erroneously detect that the filter is dirty. Install a flow control valve or a manual slow-opening valve towards the
direction of irrigation.

4. Check that all the drainage outlets, including the wastewater discharge valve, are at atmospheric pressure, and
that they do not increase or boost the drainage flow rate.
Washing does not occur
1. Check the minimum pressures maintained throughout the washing cycle, as well as the minimum washing flow
rates, with the table for each filter model.
2. The auxiliary filter should be cleaned if it is stuck.
3. Clean with acid or replace: connecting microtubes, needle valves, restrictors, Cebollo valves or solenoids (if it is
electric) clogged with deposits.
4. Check and/or change: worn out gaskets or perforated membranes
Water leaks
Dripping or constant water leakage from yellow microtubes are signs of malfunction. Disassemble them in the direc-
tion opposite to that of the water, from the dripping point to the control element which allows the water to pass, cle-
aning each element. In case of worn out gaskets or perforated membranes, remove, check, and change all of them
for safety, including internal ones.
Cartridge with broken screen
Please note that this can lead to jamming in the emitters. Make sure that sharp objects cannot enter by placing a
screen before the filter. The screen may also be worn out due to abrasion, normal operation, and silica, weakening
it and causing it to break. We suggest replacing the screen before it breaks.
