Maintenance and Support

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.
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 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.
EMERGENCY MANAGEMENT
The only machine part exposed to a fire hazard is the motor. However, a fire hazard also exists for materials
unrelated to the machine but located close to it.
In the event of a fire, use extinguishers approved for electrical devices.
Liquid spills
The pumped liquid may escape from the machine as a result of installation, start-up, maintenance or
disposal, unforeseen breakages or excessive wear of sealing devices.
If spills can be dangerous or harmful to human, animal or environmental health, install a waterproof
collecting basin around the machine. Collect the liquid and dispose of it correctly, without dispersing it in the
environment.
DISPOSAL
The devices marked with this symbol may not be disposed of in domestic waste but disposed of in
appropriate local collection centres for Waste Electrical and Electronic Equipment (WEEE), or delivered to the
distributor who is required to collect them. The illegal or improper disposal of the product involves severe
criminal and/or administrative penalties.
