OPERATION
Once all the hydraulic and electric connections have been
done for the hydraulic priming of the pumps and collectors,
proceed as follows:
∙ close all the valves of the distribution system
∙ open all the valves of the group, included those of the
membrane ways
From this moment any operations on pump ducts,
pressure sensor, etc. must be done after having cut
the voltage off from the distribution board.
Press the [AUT/MAN] pushbutton for MANUAL start and sub-
sequently push the [ON/OFF] pushbutton to start the desired
pump. Verify the rotational direction of the pumps.
Check the direction of rotation (only three-phase pumps)
After starting the pump, press the [ON / OFF] button to stop
the pump and check the direction of rotation. Perform the op-
eration on all pumps.
If the two pumps have the direction of rotation reversed:
Disconnect the power supply and invert two phases of
the general power cable from the electrical panel.
If only one pump has the wrong direction of rotation:
Remove power and reverse the wires in the terminals
of the contactor power for that pump.
Check the priming of the pumps
Keeping all the drawing valves closed:
∙ Press the [AUT/MAN] button for MANUAL mode start
∙ Start one pump and verify that max pressure is reached
∙ Stop the pump

Check that the circuit pressure reaches the maxi-
mum value. If not, repeat the filling operations of the
collection of aspiration to the pump.
∙ Repeat the operation on the other pump
Automatic Starting of the standard unit
After having forced pressure into the unit through the manual
driving of the pump, set the pump selectors to the AUTOMAT-
IC position.
From then on, the unit will automatically work according to
the quantity of water withdrawn by its use.
Change of the working pressure
Our units are set and tested during manufacture and the
working pressure is set up according to the characteristic
curve of the motor pumps used.
It is however possible to modify the working pressure value by
changing the setting of the pressure switch used.
The values of pressure switch calibrations must be
between the minimum and maximum working pres-
sure levels foreseen for the pump used in the unit
and reported on the plate applied to the pumps themselves.
∙ Cycle 1
Pressure switch 1 -> Pump1 | Pressure switch 2 -> Pump 2
∙ Cycle 2
Pressure switch 1 -> Pump 2 | Pressure switch 2 -> Pump 1
∙ Cycle 3
Pressure switch 1 -> Pump 1 | Pressure switch 2 -> Pump 2
