3.-
High flow rate at the start of irrigation. There is a high pressure
drop and the differential pressure control devices erroneously de-
tect 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 was-
hing 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 val-
ves, 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 direction opposite
to that of the water, from the dripping point to the control element
which allows the water to pass, cleaning 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 sug-
gest replacing the screen before it breaks.
