During the self·priming phase, all laps, valves, etc. on the delivery hose must be fully open in
order to allow the air inside the hose lo escape.
Before plugging in and starting the pump for the first time, it is necessary that the suction hose
and the pump are completely filled with water in order for suction to take place. For use in wells
or when the water level is lower than the pump, a suction hose must be used that is equipped with
the foot valve, This will allow the suction hose to remain filled with water after the first time that
it is filled and will prevent the emptying of thehose when the pump shuts off automatically,
avoiding any problems when restarting.
Boosters with external electronic safety device
The electronic device does not work if the highest point of use is over 50 Feet above the controller:
The pump used in combination with the electronic device must not absorb more than 10 Amps
(15 Amps for USA versions) and must have a maximum pressure between 50 psi (115 feet)
and 110 psi (250 feet).
The electronic device carries out two operations:
•
Permits the pump to operate in automatic: starting when the tap is opened and stopping
approximately 15 seconds after the tap is closed.
•
Protects the pump from dry-running: the special safety device automatically deactivates the pump
when there is no water being sucked thereby preventing possible damage. The stop is signalled when
the red LED on the display lights thereby allowing the lack of water to be noticed.
Installation
The pump inlet pressure must not exceed 28 psi.
The pump will not operate if the tap is over 50 feet above the level of the pump.
The electronic device is fitted on the delivery side of the pump by connecting the 1" male connector of the
device's inlet to the threaded female of the pump's outlet. If the pump does not have a 1" female outlet a
connector must be used. After the electronic device has been fitted, connect the connection cables to the
pump.
A filter should be fitted to the suction inlet of the pump before connecting the suction hose to the pump.
The filter is necessary to avoid damage to the electronic device and subsequent operating problems.
Activate the pump by connecting the plug on the connection cable into a power supply socket.
Led Display
The electronic device is equipped with a display having 3 LEDs that indicate the operating status of the
pump:
GREEN LED: this lights as soon as the electronic safety device is connected to the mains power supply.
YELLOW LED: this lights when the pump is running and turns off when the pump stops.
RED LED: this lights when the running is prevented due to lack of suction water or if the pump
malfunctions.
RESET button: this button is used to restart the pump after the flow of water has been restored. The
electronic device is also equipped with an automatic reset that automatically attempts to restart the pump
three times: after 1 hour, after 5 hours and after 20 hours. If the pump does not start, the electronic device
will permanently block. lf this occurs, disconnect the plug from the socket and reinsert it. The device can in
any case be manually reset before the 3 attempts have elapsed.
N.B.; if thepump does not start, check that the suction hose and pump casing are full of water.
