12 Decommissioning and removal
If the system needs to be decommissioned, first
disconnect the unit from the power supply and
water circuit, and then separate the different
materials of the unit in order to eliminate them
separately.
Use public or private waste management compa-
nies for the disposal of the product or compo-
nents.
Check that there are no residues of any polluting
liquids inside the pump and pipes.
The unit equipped with diesel motor may have
batteries which contain lead and electrolytic liquid
including acids, solutions of water and antifreeze
liquid, oil and fuel.
Pay particular attention to the elimination of bat-
teries and make all actions necessary to prevent
any spillage of liquid on the ground that can pol-
lute the environment.
If materials of the unit are spread in the environ-
ment, they can create serious environmental
damages.
All materials and components must be collected,
and eliminated in accordance with the regulations
in force. Even during the installation operations
and handling, the following materials must be sent
to centres specialised in the collection and
removal of waste:
• Electromechanical and electronic components
• Electric cables
• Batteries
• Strainers
• Oil drain
• Mix of water and antifreeze
• Rags and smooth material used for various opera-
tions or cleaning
• Materials for packaging
Liquids and polluting materials must be eliminated
according to the specific standards in force.
Make a separated elimination allow to retrieve
equipment, and to reduce pollution.
