Off service and demolition

In case of dismantling and demolition, the pump components are not so dangerous and do not require special precautions. In order to facilitate
recycling, all materials composing electrical system and thermoplastic components shall be separated from the machine.
INFORMATION TO USERS - under Article 13 of Law 25, July 2005, n° 151 "Implementation of Directives 2002/95/EC, 2002/96/EC and
2003/108/EC: Restriction of the use of certain Hazardous Substances in electrical and electronic equipment and Waste of Electrical
and Electronic Equipment"
Suitable separate collection, followed by decommissioned pump recycling, treatment and environmentally-sound disposal, helps to avoid pos-
sible negative effects on health and the environment and promotes re-use and/or recycling of the materials of which the equipment is made.
Owners who dispose of the product illegally will be liable to the administrative penalties envisaged by the regulations in force. In case of off
service and demolition, follow scrupulously the local antipollution norms. Proceed to the differentiated disposals according to the list of different
materials composing the pumps in the standard version reported in the annex.
DON'T WASTE THE ENVIRONMENT WITH OUT OF USE MATERIALS
