!AVVERTENZE
Indicazioni per il corretto smaltimento del prodotto ai sensi della Direttiva Europea 2011/65/EU e D.Lgs 4 marzo 2014 n.27.
Il simbolo del cassonetto barrato riportato sull’ apparecchiatura indica che il prodotto alla ne della propria vita utile deve essere 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 elettronici 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 smaltimento
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’ ambiente. 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.

Devido ao refrigerante, ao óleo e a outros componentes contidos no Ar condicionado, a desmontagem deve ser realizada por um insta-
lador prossional de acordo com os regulamentos aplicáveis. Contacte as autoridades correspondentes para obter mais informações.
!ADVASEL!
At produktet ikke må smides ud sammen med almindeligt husholdningsaffald, men skal bortskaffes i overensstemmelse 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 overenss-
temmelse med de gældende bestemmelser.
Kontakt de pågældende myndigheder for at få yderligere oplysninger.
!VOORZICHTIG
Dit houdt in dat uw product niet wordt gemengd met gewoon huisvuil wanneer u het weg doet en dat het wordt gescheiden op een
milieuvriendelijke manier volgens de geldige plaatselijke en landelijke reguleringen.
Vanwege het koelmiddel, de olie en andere onderdelen in de airconditioner moet het apparaat volgens de geldige regulering door een
professionele installateur uit elkaar gehaald worden. Neem contact op met de betreffende overheidsdienst voor meer informatie.
!FÖRSIKTIGHET
Det innebär att produkten inte ska slängas tillsammans med vanligt hushållsavfall utan kasseras på ett miljövänligt sätt i enlighet med
