Informativa al consumatore come previsto dalla normativa europea

2002/96/CE riguardante i rifiuti di apparecchiature elettriche ed elettroniche.

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.

Ulease don-t let the pipe and the parts in the unit collide each other4

Yhe connection between outdoor liquid pipe and the distributing pipe is flared type4 Ulease

expand the pipe with the special tool for W:76F after installing the expanding nut4 Gut if the

projecting pipe length has been adjusted with the copper pipe gauge2 you can use the original

tool to expand the pipe4

Xince the unit is with W:76F2 the expanding oil is ester oil2 not the mineral oil4

Gesides2 while testing2 the valves should be close4

84 Wefer to the below figure to charge the nitrogen into the unit to take a test4 Sever use the

chlorin2 oxygen2 flammable gas in the leakage test4 Fpply pressure both on the gas pipe and the

liquid pipe4
