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
DANGER - ELECTRIC SHOCK RISK
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 subsequently 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 operation on all
pumps.
DANGER - ELECTRIC SHOCK RISK
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.
DANGER - ELECTRIC SHOCK RISK
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.
