Diagnostic rotuting
1) Water leaks by the drainage of the Globo Valves.
Wait to have a pressure in the system of 1Kg/cm² as minimum, if it is necessary you must increase the pressure or
the flow in order to reach the minimum pressure. When the flow or the pressure is low, sometimes you need to put
stabilizing valves at the exit of the system in order to increase the pressure.
2) High pressure loss when starting the conduit filling.
Excess of flow due to low pressure on the conduits, install a manual valve which must be closed, or use a system with
an intelligent controller and stabilizing valve. After some time and when the system conduits are filled, the pressure
loss and flow must be as indicated in the charts. The control boards have a delay timer to prevent that. Read the con-
troller chapter of your model.
3) Repeated backflushing. They can appear by different reasons:
• To have a high headloss (See the previous point)
• Too little delay time at cleansing start (Read the electric controller chapter of your control board).
• Due to excessive water contamination, it is convenient to lower the flow till the conduits clean up and then ele-
vate progressively the flow to normal values.
• Check that the differential pressure is the adequate.
• It is possible that the system do not have a correct backflushing, for lack of minimum pressure, for lack of mini-
mum flow, or for lack of minimum backflushing time.
4) Electrical programmer. The most usual incidences are:
• Alarm signal on the screen due to interruption of power supply. To solve it press RESET, the controller will work,
even with the alarm signal on.
• The controller doesn't power up. Turn the power switch on, and check power supply voltage. With the 12 Volts
battery powered models, check battery voltage.
5) There's no cleansing with pressure loss.
Check that the connectors at the solenoid's bases are correctly plugged in, and that the safety bolts are tight.
Check that the valve to the auxiliary filter is open.
It is possible that the pressure connections to presostat or sensors are incorrectly connected or adjusted.
The solenoids or the three ways valves may be on incorrect manual position.
6) Suckers problems
If the suckers leak at the start when applying pressure, or a foreign body has entered inside, close the optional
shutoff valve or neutralize the pressure before disassembly (unscrewing from its base). Clean, screw again and open
the shutoff valve.
Start after prolonged stop.
1) Restart increasing the pressure slowly. Make two or three consecutive cleansings, pushing the manual pushbutton
at the control board. Check it doesn't reach the system's maximal operating pressure.
2) The rings may be compacted and dry by the contaminants. Disassemble and clean following the manual instruc-
tions and pictures.
3) The controller is equipped with a counter showing the number of cleansings done. If you reset to zero, annotate
the number. Some controllers have a total counter.
4) It is convenient to replace rings each 7.000 cycles.
5) Change diaphragms and seals each 14.000 cycles.
6) Clean the solenoids when the yellow draining microtubes get obstructed.
7) See the first set up to find the fault better.
