Operation - System Stopped
In the event of a water shortage during aspiration, the device will
recognise the fault, signal the same with the red pilot light Failure,
and stop the pump to protect it from dry running.
After eliminating the causes of the stopping it is sufficient to press
the red Restart button to restore normal operation.
In case of a temporary electricity cut-off the device will automatically
start up again when the power returns.

MAINTENANCE
The pump should be serviced by qualified personnel only, after having been disconnected from
the power mains. No routine maintenance is required so long as the following precautions are
taken:
-If there is a risk of freezing, it is necessary to empty the pump casing; then fill the pump before
it gets working again and be sure the ambient temperature is over the water freezing point.
-Make sure the pump never works dry. (Even if the Control-Press stop the pump in case of dry
running)
-On D.C. motors the brushes must be periodically checked for consumption and spring
pressure.
-If the pump does not work for a long time its better to empty the pump casing, and clean it.
-If a filter and a foot valve are installed check periodically their efficiency.
Checking the Operation
In the case of faults it is recommended to apply a ball valve to the
output of the CONTROLPRESS.
This allows for testing the operation of the pump and the device and
excluding the system by means of the valve for the purpose of
troubleshooting and removing the cause of the malfunctioning.
