6 INSTALLATION
Warning - danger!
All installation and assembly operations must be performed with the appliance
disconnected from the mains power supply (fig. 3).
Warning - danger!
Before use, always perform a visual check on the appliance, and especially
the plug (A12) and power cable (A8), for damage. A damaged appliance must
not be used; in the event of damage, have the appliance inspected by the
Service Centre or an authorised electrician.
Warning - danger!
If the power cable (A8) is cut, the warranty becomes null and void and a
replacement genuine power cable (A8) must be installed during the repair,
at the customer's expense (even in case of repair under warranty). If it is
necessary to extend the power cable (A8), only use an extension with gauge
at least equal to that of the original power cable (A8). Never lift the appliance
or remove the plug (A12) from the socket by means of the power cable (A8).
6.1
Fitting the delivery hose
Connect a hose having inside diameter of at least 25 mm (1"), with
threaded fitting, to the delivery fitting (A2). A hose having diameter 32
mm (1-1/4'') is preferable. Smaller hose diameters drastically reduce
the appliance's flow rate. To ensure an airtight connection, use Teflon
tape (12 - 15 layers) (fig. 4).
The use of a delivery hose with foot check valve is highly
recommended, in order to prevent the flowback of water when the
appliance is switched off.
Installing a quick shut-off valve to disconnect the hose in a suitable
point simplifies cleaning and maintenance.
6.2
Bleeding the appliance
The appliance is bled automatically provided it is immersed in
the liquid to sufficient depth.
Once the appliance has been started, make sure that the
delivery hose is open (not shut by a tap, for example) to allow
the residual air to escape.
6.3
Notes on the place of installation
The appliance is designed to be installed in a well at least 10 cm in
diameter, with an immersion depth of up to 16 m (fig. 5).
Before installing the appliance, a recovery rope must be fitted to the
eye-ring (A5) to allow it to be lowered into place/recovered easily
(fig.6).
If possible, the appliance should be suspended in the pumped liquid,
far enough off the bottom to prevent it from sucking in solids of
inappropriate size which may foul the suction strainer (A1) or jam
the impeller (fig. 6).
The appliance is cooled by the water it transports and the water in
which it is immersed. Make sure that the appliance is completely
immersed in the pumped liquid to ensure that it is cooled.

Safety Measures
Since the appliance does not have an ON/OFF switch, it should be
connected to a socket controlled by a supplementary ON/OFF switch.
Throughout all installation and use procedures, please bear in mind
that water leaks may cause damage.
Warning - danger! Dry operation
If the appliance runs for more than 5 minutes with the water suction
point closed, it may be damaged due to overheating. Switch off the
appliance when the normal water flow is obstructed.
Dry operation will damage the appliance beyond repair, so never allow
it to run dry for more than 10 seconds.
7 ADJUSTMENTS
7.1
Preliminary adjustments
Once the delivery hose has been connected, the appliance
is ready for use. Bear in mind that if a socket with ON/OFF
switch is not used, the appliance starts as soon as the plug
(A12) is connected.
8 START-UP
Warning - danger!
All installation and assembly operations must be performed with the appliance
disconnected from the mains power supply (fig. 3).
8.1
Start-up
After connecting the appliance as described in point 6 and after
implementing all safety instructions, the plug (A12) can be connected.
8.2
Priming the appliance
The appliance sucks in water through the suction strainer (A1) in its
base and conveys it along the hose connected to the delivery fitting
(A2).
Make sure that the appliance is continuously immersed in water when
in operation, to ensure that it does not run dry. When the user outlets
are shut, switch off the appliance using the ON/OFF switch or by
disconnecting the plug (A12).
8.3
Technical information
The appliance's stated flow rate values are maximum values, which
are reduced if the recommended head is exceeded and external
components (e.g. delivery hose, elbows, restrictors, etc.) are used.
This should be borne in mind when choosing the pump. The actual
flow rate for specific installation conditions is stated in the flow rate
graph (fig. 7).
