6 WEEE DIRECTIVE APPLICATION - DIRECTIVE 2012/19 / EU
The crossed-out wheeled bin symbol indicates that within the European Union all electrical and electronic products at the
end of their useful life must be collected separately from other waste.
Do not dispose of this equipment in unsorted municipal waste. Assign the equipment to the appropriate collection centers
for electrical and electronic waste or return it to the retailer when purchasing a new equivalent type of equipment.
Appropriate separate collection of equipment to start the subsequent recycling, treatment and environmentally compatible
disposal helps to avoid possible negative effects on the environment and health due to the presence of hazardous sub-
stances in electrical and electronic equipment and resulting from an incorrect disposal or improper use of the same
equipment or parts thereof, the separate collection also favors the recycling of the materials of which the equipment is
composed.
The current legislation provides for sanctions in case of illegal disposal of the product.
