SAFETY MEASURES
Before starting the pump, read this instruction booklet carefully and keep it in a safe place
forfuture reference
For safety reasons, the pump must not be used by anyone who has not read these
instructions.
The pump must not be used by anyone under 16 years of age or by anyone who has not
readand understood the present instruction booklet. Keep children well away from the
pump whenin operation..
The power cord must never be used to carry or move the pump. Always use the pump’s
handle.
When handling the pump, while it is connected to the electric power supply, you should
avoid all contact with water.
Never remove the plug by pulling on the power cord.
Before taking any action on the pump, always remove the plug from the power socket.
There should be no individuals present in the liquid that is being pumped while the pump is
inuse.
If the power supply cord has been damaged, it must be replaced by the manufacturer or his
authorized customer support service in order to avoid all risks.
Overload protection. The pump has a thermal overload safety device. In the event of any
overheating of the motor, this device automatically switches off the pump. The cooling time
isroughly 15 to 20 minutes, then the pump automatically comes on again. If the overload
cut-out is tripped, it is essential to identify and deal with the cause of the overheating. See
Troubleshooting.

STARTING THE PUMP
Given the different provisions applicable to the safety of electric systems in different
countries, make sure that the pump system, as concerns its intended use, is in
accordance with current
legislation.
Before starting the pump, make sure that:
•
The voltage and frequency specified on the pump’s nameplate coincide with those of the
available power supply;
•
there are no signs of damage to the pump or its power cord;
•
The electric connection is made in a dry place, protected against any risk of flooding;
•
The electric system is complete with a residual current circuit-breaker (30 mA) and an
efficient earthing connection;
•
Any extension cords must comply with the requirements for electric safety.
Fill the pump casing and suction hose with clean water before starting the pump for the
first time. If the pump is installed above the water level, filling must be performed slowly
until the water overflows; wait a few seconds to make sure that all the air has escaped
and top up until the level has stabilised.
If the pump is installed below the water level (below head), bleed the air from the pump
casing by opening the filler cap. The pump will fill with water independently.
Plug the pump into the socket, start the pump and wait for the water to exit. If water has
not exited within 2-3 minutes from when the pump was switched on, turn the pump off
and repeat the filling operation again.
Attaching the suction hose
•
Fit the suction hose from the water source to the pump making sure that the pump is
above the water level. Do not position the suction hose above the level of the pump (to
avoid air bubbles forming in the suction hose).
•
The suction hose should be mounted in such a way that it does not create any
mechanical stress on the pump.
•
The foot valve should be placed at least 12 inches below the minimum water level.
•
The pump will draw water only when the suction hose is completely filled with water.
•
The suction hose and the pump’s suction inlet should be of the same diameter.
Attaching the delivery hose
•
To get the best performance from the pump, it is recommended that the diameter of the
delivery hose is at least 1"
•
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.

Booster with integrated electronics
Installation
The pump's inlet pressure should not exceed 28 psi.
The maximum suction depth should be less than 26 feet
The device will not pump liquid if the tap is more than 50 feet above the level ofthe pump.
Due to the non-return valve in this model, the suction hose cannot be filled through the filler
cap on the pump.
Using the pump
Plug the electric cable into the socket. The pump will automatically begin to run.
lf the suction phase is not activated within 120 seconds, the pump will shut-off automatically. The pump
will then try 2 more attempts to sell prime for 120 seconds each.
The electric pump is equipped with an integrated electronic device that allows the unit to automatically
intervene in the following ways:
•
Automatic operation of the pump
The pump automatically starts when a tap is opened and shuts»ofl approximately 10 seconds after it is
closed.
•
Protection against repeated starting due to leaks in the delivery section of the system
It there are traces of leaks on the delivery of the system, the pump will continue to turn on and off even if it
is not drawing water. Even a small leak (a few gph) could be enough to cause a drop in pressure which
would start the pump. If in this case the leak is not found and fixed, the pump will turn off and remain shut-
of after 40 consecutive start-up attempts.
This is signalled by the red "Alarm" LED: 2 successive flashes followed by a pause. After having resolved
the leak, the RESET must be pressed to restart the pump.
The pump automatically resets after having remained for 12 hours in alarm. The alarm is activated once
again alter 40 ON-OFF-ON cycles if the same condition should persist.
•
Dry- Run Protection
If the pump senses that it is not drawing any water, it will automatically switch-off after approx. 45
seconds.
The red "Alarm” LED on the electronic display will begin to flash. After having restored the flow of water to
the pump, press the RESET pad to restart the pump,
lf the alarm persists, or rather the user does not re-establish the flow of water and reset the pump, the
automatic reset will attempt to restart the pump after 1 hour, 5 hours and 20 hours, and then once every
24 hours. The electronic display continues to signal the lack of water from the first intervention of the dry
run protection up until the pump starts to operate correctly; flashing red LED with one flash and one
pause. After having re-established the flow of water, press the RESET button to restart the pump.
•

RECOMMENDATIONS
To ensure the proper operation of the pump, it is important to comply with the following
recommendations:
The pump should not operate with the delivery tap completely closed (except for
electronically controlled pumps).
The pump must never be allowed to run dry.
•
The diameter ot the suction and delivery hoses must not be less than the relative inlet or outletof the
pump. (1” )
A hose with a greater diameter should ideally be fitted to the suction inlet when the suction height
exceeds 12 feet. Do not use metal connectors on the pump‘s threads.
•
Connect the suction hose including a foot valve avoiding counterslopes, traps, goosenecks and kinks in
the hose.
•
Place the pump in a level, stable and dw place, and away from inflammable or explosive substances.
Never expose the pump to the rain or direct jets of water.
•
Make sure that the mains power connections are not subjectable to flooding, avoid that the pump is
exposed to direct jets of water and do not immerse the pump in water.
•
For boosters with tank: make sure that the preloading pressure ol the tank corresponds to the data
indicated on the pump's rating plate. If necessary, fill the tank with air to the preloading pressure through
the valve after having discharged the air from the delivery side (disconnect from the mains and open the
tap closest to the pump until there is no longer a discharge of water).
MAINTENANCE AND CLEANING
lt is absolutely essential to prevent any risk of the pump freezing. In the event ol freezing temperatures.
remove the pump from the liquid, empty it and keep it in a place where it cannot freeze.
The pump must be disconnected from the mains before performing any cleaning operation.
The pump is maintenance free.
