WARNING: Before any repairs to the electric pump, check that the power supply is disconnected and that
it cannot be accidentally reconnected during maintenance operations.
WARNING: If the electric pump is used for hot and/or hazardous liquids, inform the personnel who will
carry out the repair. In this case, clean the pump so as to guarantee the safety of the operator.
WARNING: Repairing or having the electric pump repaired by personnel not authorized by the
manufacturing company means losing the warranty and operating with unsafe and potentially
hazardous equipment.
WARNING: Pay attention to discharged liquid so that it cannot cause damage to people or things.
The electric pump does not require any ordinary scheduled maintenance. If the user wishes to prepare a scheduled
maintenance plan, bear in mind that the due dates depend on the type of liquid pumped and the running conditions.
For spare parts and documents for maintenance, contact the sales and support service.
