SPECIFICHE DI SMALTIMENTO:
Il climatizzatore è contrassegnato con questo simbolo,
ciò significa che i prodotti elettrici ed elettronici non
possono essere smaltiti insieme ai rifiuti domestici non
differenziati. Non cercare di demolire il sistema da soli:
la demolizioni dei sistemi di condizionamento, nonché il
recupero del refrigerante, dell’olio e di qualsiasi altra
parte devono essere eseguiti da un installatore qualifi-
cato in conformità alla legislazione locale e nazionale
vigente in materia.I climatizzatori devo essere trattati presso una struttura spe-
cializzata nel riutilizzo, riciclaggio e recupero dei materiali. Il corretto smaltimen-
to del prodotto eviterà le possibili conseguenze negative all’ambiente e alla
salute dell’uomo. Per maggiori informazioni contattare l’installatore o le autori-
tà locali. Le batterie devono essere tolte dal telecomando e smaltite separata-
mente conformemente alla legislazione locale e nazionale vigente in materia.

In accordance with the directive 2002/96/CE of the European parliament,
herewith we inform the consumer about the disposal requirements of the
electrical and electronic products.
DISPOSAL REQUIREMENTS:
Your air conditioning product is marked with this sym-
bol. This means that electrical and electronic products
shall not be mixed with unsorted household waste.
Do not try to dismantle the system yourself: the dis-
mantling of the air conditioning system, treatment of
the refrigerant, of oil and of other part must be done
by a qualified installer in accordance with relevant
local and national legislation.
Air conditioners must be treated at a specialized treatment facility for re-use,
recycling and recovery. By ensuring this product is disposed of correctly, you
will help to prevent potential negative consequences for the environment and
human health. Please contact the installer or local authority for more infor-
mation. Battery must be removed from the remote controller and disposed of
separately in accordance with relevant local and national legislation.

SPECIFICATIONS POUR L'ELIMINATION:
Ce pictogramme, apposé sur le climatiseur, signifie
que les équipements électriques et électroniques ne
peuvent pas être éliminés avec les déchets ménagers
non triés. Ne pas essayer de démanteler l'équipement
soi-même: le démantèlement des systèmes de clima-
tisation, ainsi que la récupération du frigorigène, de
l'huile et de toute autre partie doivent être effectués
par un installateur qualifié conformément à la législa-
tion locale et nationale en vigueur en la matière. Les climatiseurs doivent être
traités dans un centre spécialisé dans la réutilisation, le recyclage et la valo-
risation des matériaux. L'élimination correcte de ces appareils permet d'évi-
ter les effets nocifs sur l'environnement et la santé humaine. Pour plus de
renseignements contacter l'installateur ou les autorités locales. Les piles doi-
vent être retirées de la télécommande et éliminées séparément, conformé-
ment à la législation locale et nationale en vigueur en la matière.
