reaches a balanced position. Handle with care. Pay attention to the inertia of
the object (oscillations in the direction of travel, difficulty in slowing down and
stopping).
Pay attention to suspended loads. Do not stand under them. Pay attention
to people, animals and objects in the work area. Use appropriate work
area marking tools and delimiters, where necessary. Do not operate the
pump or let it pass over people.
6.2 Installation
• For installation, follow fig. A5 (basic version) or A11 (self-priming version) in
the appendix, as appropriate.
• Install the electric pump in an accessible location and protected against frost,
leave enough space around the electric pump to allow use and maintenance
operations.
• The installation position must be as shown in fig. A5 or A11, as appropriate.
Vertical (V in fig. A5 and A11) or horizontal assembly with the support brackets
not facing downwards is not allowed.
• Check that there are no obstacles to the motor cooling airflow, ensure at least
100 mm of free space from the fan (Fig. A5 and A11).
• Drain any liquid leaks, so that they cannot flood the installation site and/or
submerge the unit.
• The electric pump must ALWAYS be fastened to a concrete foundation or on
a metal structure that protrudes by at least 100 mm from the electric pump,
in all directions, sturdy enough to support it stably and with a mass at least
equal to that of the electric pump (recommended 5 times higher). Use screws
and tightening torques according to fig. A6 and A7 (basic version) and fig. A12
(self-priming version).
• If the pump runs with liquid at a temperature above 50 °C, anchor the pump
only on the side of the motor bracket and leave the suction side bracket free
(versions with two brackets). Install elastic elements between the pump and
the pipes to compensate for thermal expansion.
• Place anti-vibration joints between the pump and the foundation to minimise
the transmission of vibrations.
6.3 Additional protections and guards
• The surfaces of the electric pump may reach high temperatures based on the
temperature of the pumped liquid. If deemed necessary, provide guards to
prevent accidental contact, without interfering with the normal functionality
of the machine (e.g. motor cooling).
• High-speed liquid splashes may be generated in the event of breakage,
installation errors or during filling operations. Provide appropriate fixed or
temporary guards, in the event that liquid spills can be dangerous or harmful
to human or animal health.
6.4 Accessories
• Hydraulic connections kit: they enable connecting the hydraulic part to the
pipes (according to the type of connection desired).
7 COMMISSIONING AND DECOMMISSIONING
CAUTION:
• Pay attention to the drained liquid so that it cannot harm people or things.
• Do not start the appliance without the safety devices (mechanical guards and
electrical protections required).
• During operation, the external surfaces of the pump and motor may exceed
40°C (104°F) if the liquid pumped is not at room temperature.
• Do not touch the unit without adequate protections.
• Do not place flammable material near the pump.
• The electric pump must NOT be started before filling.
• Its dry use may irreparably damage the mechanical seal.
• Do not operate the pump with the suction and delivery valves closed for more
than 5 seconds.
• Do not expose the inactive pump to freezing temperatures, freezing the liquid
will damage the pump.
7.1 Priming
Case with liquid level above the pump or pressurised inlet line (detail B in fig. A5,
basic version, and fig. A11, self-priming, in the appendix):
• Close the delivery valve (detail 8 in fig. A5 or fig. A11).
• Remove the filling caps (A1 and A2 in the figures).
• Open the suction shut-off valve (detail 4 in the figures) to allow the liquid to
enter and wait until the water comes out of the pump.
• Close the suction valve and screw the filler caps (see tightening torques in fig.
A6, A7 and A12 in the appendix).
Case with liquid level below the pump (detail A in fig. A5, basic version, and fig.
A11, self-priming, in the appendix):
• Close the delivery valve (detail 8 in the figures) and open the suction valve
(detail 4 in the figures).
• Remove the filling caps (detail A1 in the figures).
• Using a funnel, fill the pump until the water comes out (it may be required to
repeat the operation several times).
• Reposition and tighten the filler caps (see tightening torques in fig. A6, A7 and
A12 in the appendix).

HORIZONTAL / SELF-PRIMING MULTISTAGE PUMPS
7.2 Pump start-up
Before start-up, check that:
• The electric pump is correctly connected to the power supply.
• The delivery and suction connections are properly tightened.
• The electric pump is adequately filled (see "Priming" section).
• The delivery shut-off valve (8 in fig. A5 and fig. A11) is closed and the suction
valve (4 in fig. A5 and fig. 11) is open.
Start the motor and gradually open the valve on the delivery side of the pump.
After a few seconds of noisy operation, at full speed, the appliance must operate
silently and regularly, without any pressure changes to discharge any air. The
self-priming versions may require a longer time to discharge all the air from the
suction pipe if this is not full (about 1 minute). Refer to the Troubleshooting table
if this does not occur. After a few seconds of operation, it may be required to
remove the air that accumulates in the highest points of the system and of the
pump.
7.3 Emptying the pump (decommissioning)
Should it be required to empty the pump for maintenance or for long periods of
inactivity:
• Close the shut-off valves of the delivery and suction pipes (4 and 8 in fig. A5 or
fig. A11, in the appendix).
• Discharge the pump pressure by partially loosening the drain plug (A3 in fig.
A5 and fig. A11). Once the pressure has run out, fully remove the drain plug (A3
in fig. A5 or fig. A11) and wait for emptying.
• Once emptying is complete, reposition and tighten the caps again (see
tightening torques in fig. A6, A7 and A12 in the appendix).
Liquid may remain in some internal parts of the pump. For complete
removal, it is required to disassemble the pump.
Make sure that the drained liquid does not harm people or things.
8 MAINTENANCE AND SUPPORT
WARNING: Before any operation on the electric pump:
• Make sure that the electrical voltage has been interrupted and that it
cannot be accidentally restored during maintenance operations.
• If the pump is single-phase, make sure that the capacitor is discharged.
• Close the shut-off valves upstream and downstream of the appliance.
WARNING: If the electric pump is used for hot liquids and/or liquids that
are dangerous for humans, strictly notify the personnel who will carry out
the repair. In this case, clean the pump in order to ensure operator safety.
Risk of spills of the fluid pumped by the machine: The pumped fluid may
be pressurised even with the machine stopped: before intervening,
isolate the machine from the system by closing the upstream and
downstream shut-off valves and partially unscrew the filler cap to reduce
the internal pressure. Liquid may leak during this step
drained liquid does not harm people or things.
WARNING: Repairing or having the electric pump repaired by personnel
not authorised by the Manufacturer voids the warranty and means
operating with unsafe and potentially dangerous equipment.
Wait for the surfaces to cool down before working on the appliance.
The electric pump does not require any scheduled routine maintenance. Have the
electric pump repaired only by personnel authorised by the manufacturer so as to
keep your warranty valid and not to impair the safety of the appliance. Use only
original spare parts or parts approved by the manufacturer. For spare parts and
special maintenance manuals, contact the Manufacturer.
Always use the required PPE (refer to the relevant section).
Regularly check that no condensation is formed in the motor (if there are drainage
holes).
The components that are normally subject to wear are: the mechanical seal (30.6
in fig. A14). Wear is associated with work conditions and loads. Regular checks
on the state of wear and tear of these components will improve the reliability
and increase the service life of the product. Perform checks on a monthly basis,
more frequently if the working conditions so require, and during the first 500
hours of work.
• Check for any liquid leaking from the mechanical seal by checking the
equipment on the ground.
Check guards for proper positioning and safety devices for proper operation on
a daily basis.
It is advisable to check the condition of cables (especially at the cable glands)
every month and clean the system filters and/or suction grille.
Prevent dust build-up on the motor and obstructions to the cooling airflow.
Make sure that the
