DANGER

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

WARNNG

Users should always follow the accident prevention laws in force in the country where the product is installed.

DANGER

Before repairing or servicing the electropump, disconnect it from the socket and/or turn the main switch to Off (when present) to interrupt the power supplied to the electropump. This prevents the electropump from accidentally restarting and from causing accidents to people and/or damages to the people.
