All products bearing this symbol are waste electrical and
electronic equipment (WEEE as in directive 2012/19/EU)
which should not be mixed with unsorted household
waste. Instead, you should protect human health and the
environment by handing over your waste equipment to a designated
collection point for the recycling of waste electrical and electronic
equipment, appointed by the government or local authorities.
Correct disposal and recycling will help prevent potential negative
consequences to the environment and human health. Please contact
the installer or local authorities for more information about the
location as well as terms and conditions of such collection points.
