Maintenance And Support - Franklin Electric E-Tech Serie Manual De Uso

ENGLISH
Translation of original instructions
Check the weight of the machine before starting any lifting operations.
The weight is indicated on the rating plate. The suspension point provided
on the pump/electric pump does not match the machine centre of mass.
Wrap the belts around the appliance, as shown in fig. A1.
During lifting, the machine will tend to rotate around the lifting point until it
reaches a balanced position. Handle with care. Pay attention to possible sudden
overturning and 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
• Follow fig. A9 in the appendix for the installation.
• 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. A9. Upright mounting with the
motor facing downwards (V in fig. A9) or horizontal mounting 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. A9).
• 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. A2.
• If the pump runs with liquid at a temperature above 50°C, 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.
• Liquid may leak during these steps. It is recommended to remove it
and dry the pump well with compressed air to best preserve it.
7 . 1 Priming
Case with liquid level above the pump or pressurised inlet line (detail B in fig. A9
in the appendix):
• Close the delivery valve (detail 8 in fig. A9).
• Remove the filling cap (detail A1 in fig. A2).
• Open the suction shut-off valve (detail 4 in fig. A9) 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.
A2 in the appendix).
12
MONOBLOC VERTICAL MULTISTAGE PUMPS
Case with liquid level below the pump (detail A in fig. A9):
• Close the delivery valve (detail 8 in the figure) and open the suction valve
(detail 4 in the figure).
• Remove the filling cap (detail A1 in fig. A2).
• 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 cap (see tightening torque in fig. A2 in the
appendix).
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. A9) is closed and the suction valve (4 in
fig. A9) 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. Refer to
the Troubleshooting table if this does not occur. After a few seconds of operation,
it may be required to expel 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. A9,
in the appendix).
• Discharge the pump pressure by partially loosening the drain plug (detail A2 in
fig. A2, in the appendix). Once the pressure has run out, fully remove the drain
plugs and wait for emptying.
• Once emptying is complete, reposition and tighten the caps again (see
tightening torques in fig. A2).
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. Make sure that the
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 (30.01
in fig. A10). 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.
