PRODUCT CONFORMING TO EU DIRECTIVE 2012/19/EU and Italian Legislative Decree 49/2014 in accordance with article 26 of Legislative Decree of 14 March 2014, no. 49 “Implementation of Directive 2012/19/EU on waste from electrical and electronic equipment (RAEE)” The barred wheeled bin symbol appearing on the appliance or on its packaging indicates that the product must be collected separately from other waste at the end of its useful life. The user must therefore deliver the decommissioned product to an appropriate local facility for separate collection of electrotechnical and electronic waste. Alternatively, the appliance to be scrapped can be delivered to the dealer when purchasing a new equivalent appliance. Electronic products measuring less than 25 cm can also be delivered for disposal, at no cost, to electronic equipment retail shops having a surface area of at least 400 m2, without having to purchase other products. Proper separated collection of the decommissioned appliance for its subsequent recycling, treatment, and eco-compatible disposal helps to prevent negative effects on the environment and human health, besides encouraging reuse and/or recycling of its constituent materials. Install the product in a room with a normal level of pollution.
