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 Assembling the appliance
Before the appliance is put into operation, the suction and delivery
hoses must be connected. Place the appliance in a stable position on
a flat surface, in a location protected from flooding (fig. 4).
To prevent the transmission of vibrations to the pipes or walls, place
the appliance on a rubber mat and use lengths of hose (which must
be resistant to suction and pressure) immediately upstream and
downstream of the appliance (fig. 5) to dampen the vibrations.
6.2 Fitting the suction hose
The suction hose conveys the water from the suction point to the
appliance. Connect the suction hose to the threaded fitting (A1).
Check that the suction hose fitted is airtight, since any leaks may
reduce the appliance's flow rate or completely prevent it from drawing
in water. The suction hose must be at least 25 mm (1") in diameter
and must be resistant to crushing and vacuums. Use of a suction hose
with foot valve is recommended. To ensure an airtight connection,
use Teflon tape (12 - 15 layers) (fig. 6). Make sure that there is
sufficient water in the suction point and that the hose suction zone is
permanently below the water level.
Since the maximum suction lift of self-priming pumps is 8 metres,
the appliance must be no more than 8 m above the water level in
the suction point. The horizontal part of the suction hose must rise
continually from the suction point to the appliance, to prevent the
formation of air bubbles in the hose, which could impair operation of
the appliance (fig. 7).
A pre-filter must be installed between the suction hose and the suction
fitting (A1), unless the appliance has an integral pre-filter (A1 b).

6.3 Filling the appliance
Before fitting the delivery hose, completely fill the pump body (A4) and
the suction hose with water through the delivery fitting (A2). The pump
can also be filled through the filler cap (A2 b), if present (fig. 8).
Bubbles form during filling of the pump body (A4) and must be
discharged by tilting the appliance slightly in various directions.
Fill again and repeat this procedure until the water level is just below
the filling hole.
