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.
If the appliance has an integral pre-filter, more water must be added 
through the cap of the pre-filter (A1 b). Open the cap, fill with water to 
the rim and screw the cap back on by hand (fig. 8).
6.4  Fitting the delivery hose
The delivery pipe fitting is on the top of the appliance (A2). The hose 
should be connected to a hose or pipe with the largest possible 
diameter (at least 19 mm, ¾”). Smaller diameters drastically reduce 
the appliance's flow rate. To ensure an airtight connection, use Teflon 
tape (12 - 15 layers) (fig. 9).
6.5  Safety Measures
The user must prevent damage arising from the flooding of premises 
or other causes in the event of a failure of the appliance or external 
components by adopting suitable measures (e.g. installation of an 
anti-flooding protection circuit, alarm system, backup pump, collection 
tank or similar features), which must be connected to a separate, 
fail-safe electrical circuit. The safety measures must be suited to the 
specific conditions of use and must be able to reduce and/or prevent 
the damage caused by water leaks.
The user must also install a spray guard to prevent water leaks or 
splashes due to a pump failure from causing damage. A backup pump 
or a floor drain must be installed to ensure that any water from leaks 
is promptly removed. Otherwise, an alarm system can be installed 
to trigger an alarm and/or an emergency shut-down of the appliance 
and water supply in the event of a water leak, before damage to the 
equipment or property can occur.
We also recommend raising all equipment in appliance installation 
rooms about 5-10 cm above the floor so that any water leaks will 
not cause immediate damage. The manufacturer accepts no liability 
for damage caused by failure to comply with this recommendation.
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
Our appliances are preset in the factory and users must not modify 
these settings.
8 START-UP
Warning - danger!
All installation and assembly operations must be performed with the appliance 
disconnected from the mains power supply (g. 3).
8.1 Start-up
Once all the pipes have been connected and the pump body (A4) is 
full of water, the plug (A12) can be connected and the ON/OFF switch 
(A5) turned to ON. During the priming phase, the delivery pipe must 
be open to allow the air in the system to escape and to enable the 
water pressure to build up. If the suction hose is not completely full 
of water, it may take the appliance up to 7 minutes to become fully 
operational. If the water has not pressurised after the maximum 
priming time stated, switch the appliance off and proceed as described 
in the troubleshooting plan (chapter 11).
8.2  Technical information
The appliance's stated ow rate values are maximum values, which 
are reduced if external components (e.g. delivery hose, elbows, 
pre-lter, etc.) are used. This should be borne in mind when choosing 
the appliance. The actual ow rate for specic installation conditions is 
stated in the ow rate graph (g. 11).
9 MAINTENANCE
Warning - danger!
Before any maintenance procedure and/or during troubleshooting, disconnect 
the power cable (A8) from the socket.
9.1  Cleaning the filters
Clean  the  pre-lter  (if  installed,  A1  b)  regularly  with  clean  water 
and/or inspect it to ensure that it is not fouled (g. 10). Sluice the lter 
compartment with clean water.
10 STORAGE
Warning - danger!
Before any maintenance procedure and/or during troubleshooting, disconnect 
the power cable (A8) from the socket.
It is essential to protect the appliance from frost, and in case of 
temperatures of +5°C or below it must be uninstalled and stored 
in a dry place, protected from frost. After disconnecting the suction 
and delivery hoses, tilt the appliance to drain out all the water in the 
pump body (A4) through the suction tting (A1). To empty the pump 
body (A4) turn the appliance upside down to drain the water from the 
delivery tting (A2).
