8 MAINTENANCE AND SUPPORT
The electric pump does not require special 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.
Always use the required PPE (refer to the relevant section).
Before starting any work on the electric pump, make sure it has been
disconnected from the power supply and cannot be accidentally
reconnected.
Caution! In the event of an overload shutdown, appliances equipped with
automatic reset circuit breaker switches will automatically restart when
the temperature drops below the danger level.
It is advisable to check the condition of cables (especially at the cable glands)
every month and clean the filters and/or suction grille.
If the power cable is damaged, it must be replaced by the Manufacturer,
their service centre or qualified personnel.
8.1 Spare parts
Use original spare parts or parts approved by the manufacturer, in order to avoid
any risks to the service personnel's and users' health. Contact the supplier and/or
check the spare parts tables (see technical catalogue) for information.
9 EMERGENCY MANAGEMENT
9.1 Fire
• The only machine part exposed to a fire hazard is the motor and does not
involve any of its external parts.
• In the event of a fire, use extinguishers approved for electrical devices
9.2 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.
FAULT/MALFUNCTION
1) The electric pump does not get started
or stops unexpectedly
2) The electric pump gets started but
does not deliver any flow, dispenses
irregularly, or the flow rate is much
lower than values specified on the
rating plate
11 TROUBLESHOOTING
• For single-phase models with a control panel: check that the switch is set on "I". If the manual reset thermal
magnetic switch is present, press the reset button. Check that the capacitor is intact.
• For single-phase models without a control panel: check that the installed capacitor is correct, connected correctly
and undamaged.
• For models with a float, check the travel of the float and lift it manually to check that it works.
• Check whether the circuit breakers and residual current devices have been enabled; check that fuses (if any) are
intact.
• Check the electrical connection to the mains.
• Make sure the mains supply voltage is on.
• FOR PROFESSIONAL MAINTENANCE TECHNICIANS ONLY: make sure the pump can rotate freely and power
consumption does not exceed the value on the rating plate.
• For submerged units: check that the filter is not clogged and that the pump is submerged at least to the specified
minimum limit
• For surface units: check that the pump is primed and does not cavitate
• Make sure there is no air in the hydraulic conduit; vent pipes
• For three-phase models: check the rotation direction
9.3. Oil spills
• In case of breakage, the electric pump can release up to 50 cl of oil (non-toxic).
Occasional ingestion of oil is not dangerous for human health. The risk of an oil
leak should be limited as much as possible.
10 TROUBLESHOOTING
For the solution of problems related to the electric pump operation, follow the
instructions in the table below. If you do not have the necessary knowledge and
skills, contact qualified personnel. Always use PPE (see relevant section) and
appropriate tools. If the problem cannot be solved by following the instructions in
the table, contact a professional, authorised service centre.
11 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.
Domestic WEEE (single-phase electric pumps with <3 kW
power) must be handed in to private or local collection
centres, retailers or repairers, at no cost.
Industrial WEEE (all products not classified as domestic)
must be delivered to specific collection centres or retailers
or repairers.
The product is not potentially dangerous for human health and the environment
as it does not contain any harmful substances pursuant to Directive 2011/65/
EU (RoHS), but if released into the environment it will adversely impact the
ecosystem.
The illegal or improper disposal of the product involves severe criminal and/or
