Questo prodotto rientra nel campo di applicazione della Direttiva 2012/19/UE riguardante la gestione dei rifiuti di apparecchiature 

elettriche ed elettroniche (RAEE). L’apparecchio non deve essere eliminato con gli scarti domestici in quanto composto da diversi 
materiali  che  possono  essere  riciclati  presso  le  strutture  adeguate.  Informarsi  attraverso  l’autorità  comunale  per  quanto  riguarda 

l’ubicazione delle piattaforme ecologiche atte a ricevere il prodotto per lo smaltimento ed il suo successivo corretto riciclaggio. 

Si  ricorda,  inoltre,  che  a  fronte  di  acquisto  di  apparecchio  equivalente,  il  distributore  è  tenuto  al  ritiro  gratuito  del  prodotto  da 

smaltire. Il prodotto non è potenzialmente pericoloso per la salute umana e l’ambiente, ma se abbandonato nell’ambiente impatta 

negativamente sull’ecosistema. Leggere attentamente le istruzioni prima di utilizzare l’apparecchio per la prima volta. 

Si raccomanda di non usare assolutamente il prodotto per un uso diverso da quello a cui è stato destinato, essendoci pericolo di 

shock elettrico se usato impropriamente.  
Il  simbolo  del  bidone  barrato,  presente  sull’etichetta  posta  sull’apparecchio,  indica  la  rispondenza  di  tale  prodotto  alla  normativa 

relativa ai rifiuti di apparecchiature elettriche ed elettroniche. 

L’abbandono nell’ambiente dell’apparecchiatura o lo smaltimento abusivo della stessa sono puniti dalla legge.
