AVVERTENZA
Indicazioni per il corretto smaltimento del prodotto ai sensi della Direttiva Europea 2002/96/EC e Dlgs 25 luglio 2005 n.151
Il simbolo del cassonetto barrato riportato sull’ apparecchiatura indica che il prodotto alla ne della propria vita utile deve es-
sere raccolto separatamente dagli altri riuti.
L’utente dovrà, pertanto, conferire l’apparecchiatura giunta a ne vita agli idonei centri di raccolta differenziata dei riuti elet-
tronici ed elettrotecnici, oppure riconsegnarla al rivenditore al momento dell’ acquisto di una nuova apparecchiatura di tipo
equivalente.
L’adeguata raccolta differenziata delle apparecchiature dismesse, per il loro avvio al riciclaggio, al trattamento ed allo smalti-
mento ambientalmente compatibile, contribuisce ad evitare possibili effetti negativi sull’ ambiente e sulla salute e favorisce il
riciclo dei materiali di cui è composta l’ apparecchiatura.
Non tentate di smontare il sistema o l’unità da soli poichè ciò potrebbe causare effetti dannosi sulla vostra salute o sull’ am-
biente.
Vogliate contattare l’ installatore, il rivenditore, o le autorità locali per ulteriori informazioni.
Lo smaltimento abusivo del prodotto da parte dell’utente può comportare l’applicazione delle sanzioni amministrative di cui
all’articolo 50 e seguenti del D.Lgs. n. 22/1997.
CUIDADO
O seu produto não deve ser misturado com os desperdícios domésticos de carácter geral no nal da sua duração e que deve
ser eliminado de acordo com os regulamentos locais ou nacionais adequados de uma forma correcta para o meio ambiente.
Contacte as autoridades correspondentes para obter mais informações.
FORSIGTIG
At produktet ikke må smides ud sammen med almindeligt husholdningsaffald, men skal bortskaffes i overensstem-
melse med de gældende lokale eller nationale regler på en miljømæssig korrekt måde.
Da klimaanlægget indeholder kølemiddel, olie samt andre komponenter, skal afmontering foretages af en fagmand i
overensstemmelse med de gældende bestemmelser.
Kontakt de pågældende myndigheder for at få yderligere oplysninger.
LET OP
