PRECAUTIONS DURING OPERATION

●

Do not attempt to operate the unit with wet hands, this could cause fatal accident.

●

When operating the unit with burning equipments, regularly ventilate the room to avoid oxygen insufficiency.

●

Do not direct the cool air coming out from the air-conditioner panel to face household heating apparatus as this may affect the working of apparatus such as the electric kettle, oven etc.

●

Do not place plants directly under the air flow as it is bad for the plants.

●

Please ensure that outdoor mounting frame is always stable, firm and without defect. If not, the outdoor unit may collapse and cause danger.

●

Do not splash or direct water to the body of the unit when cleaning it as this may cause short circuit.

●

When operating the unit with the door and windows opened, (the room humidity is always above 80%) and with the air deflector facing down or moving automatically for a long period of time, water will condense on the air deflector and drips down occasionally. This will wet your furniture. Therefore, do not operate under such condition for a long time.

●

If the amount of heat in the room is above the cooling or heating capability of the unit (for example: more people entering the room, using heating equipments and etc.), the preset room temperature cannot be achieved.

●

This is not intended for use by young children or infirm persons unless they have been adequately supervised by a responsible person to ensure that they can use the appliance safely.

●

Young children should be supervised to ensure that they do not play with the appliance.

●

Do not climb on the outdoor unit or put objects on it.

●

Please switch off the unit and turn off the circuit breaker during cleaning, the high-speed fan inside the unit may cause danger.

●

Turn off the circuit breaker if the unit is not to be operated for a long period.

I O N

!

●

The product shall be operated under the manufacturer specification and not for any other intended use.

●

Do not put water container (like vase) on the indoor unit to avoid water dripping into the unit. Dripping water will damage the insulator inside the unit and causes short-circuit.

●

Do not use any aerosol or hair sprays near the indoor unit. This chemical can adhere on heat exchanger fin and blocked the evaporation water flow to drain pan. The water will drop on tangential fan and cause water splashing out from indoor unit.

AFTER SALE SERVICE AND WARRANTY

WHEN ASKING FOR SERVICE, CHECK THE FOLLOWING POINTS.

When it does not operate

● Is the fuse all right?

● Is the voltage extremely high or low?

● Is the circuit breaker “ON”?

● Was the air filter cleaned?

● Does sunlight fall directly on the outdoor unit?

● Is the air flow of the outdoor unit obstructed?

● Are the doors or windows opened, or is there any source of

heat in the room?

● Is the set temperature suitable?

CONDITION CHECK THE FOLLOWING POINTS

Notes

● In quiet operation or stopping the operation, the following phenomena

may occassionally occur, but they are not abnormal for the operation. (1) Slight flowing noise of refrigerant in the refrigerating cycle. (2) Slight rubbing noise from the fan casing which is cooled and then

gradually warmed as operation stops.

● The odor will possibly be emitted from the room air conditioner because

the various odor, emitted by smoke, foodstuffs, cosmetics and so on, sticks to it. So the air filter and the evaporator regularly must be cleaned to reduce the odor.

●

Please contact your sales agent immediately if the air conditioner still fails to operate normally after the above inspections. Inform your agent of the model of your unit, production number, date of installation. Please also inform him regarding the fault.

●

Power supply shall be connected at the rated voltage, otherwise the unit will be broken or could not reach the specified capacity.

PRECAUZIONI DURANTE L’INSTALLAZIONE

PRECAUZIONI DURANTE UNO SPOSTAMENTO OPPURE DURANTE LA MANUTENZIONE

●

Non riporate/rimontate da soli il condizionatore. Ne potrebbero derivare perdite d’acqua, malfunzionamenti, corti circuiti od incendi.

●

Si consiglia di fare installare il condizionatore dal rivenditore oppure da un tecnico specializzato. Potrebbe accadere una perdita d’acqua, un corto circuito oppure prender fuoco se l’installazione viene fatta di propria iniziativa.

●

Mettere a massa. Non collocare la messa a terra accanto ai tubi del gas e dell’acqua, al parafulmine oppure vicino alla messa a terra del telefono. L’installazione impropria della messa a terra potrebbe provocare una scossa elettrica.

●

Dovrebbe essere installato un interruttore automatico (per eventuali sovraccarichi) a secondo della posizione dell’unità. Senza il tale interruttore automatico si incorre in pericolo di una scossa elettrica.

●

Non installare l’unità vicino a fonti di gas infiammabile. L’unità esterna può incendiarsi se avvengono della perdite di gas infiammabile.

●

Accertarsi che il flusso dell’acqua sia scorrevole quando viene installato il tubo di drenaggio.

●

In una situazione anormale (per esempio quando c’è odore di bruciato), spegnere il condizionatore e l’interruttore automatico. Contattare il rivenditore. Se si fa funzionare l’unità in condizioni anormali si possono causare guasti, corto circuiti o incendi.

●

Una manutenzione sbagliata può causare una scossa elettrica e prender fuoco.

●

Contattare il rivenditore in caso di reinstallazione e eventuale spostamento dell’unità. Se tale reinstallazione e spostamento vengono fatti di propria iniziativa in modo non corretto, si incorre in pericolo di una scossa elettrica e potrebbe prendere fuoco.

●

Non inserisca una barretta, un asta o altri oggetti nello scarico dell’aria o nell’ingresso. Come il ventilatore è ruotando ad un’alta velocità, provocherà ferite. Prima della pulitura, sia sicuro arrestare il funzionamento e spegne l’interruttore.

●

Non utilizzare nessun tipo di filo conduttore come filo fusibile, questo potrebbe provocare danni inevitabili.

PRECAUZIONI DURANTE IL FUNZIONAMENTO

●

Evitare il contatto diretto con il flusso d’aria per un periodo prolungato, per ragioni di salute.

!

Assicuratevi di aver collegato la messa a terra.

Seguire attentamente le istruzioni.

Il simbolo sopra la figura, significa proibito.

ARRESTO

●

Se accade che qualcosa brucia nella stanza dove il condizionatore é in funzione, ventilare regolarmente la stanza per prevenire insufficienza di ossigeno.

●

Il prodotto deve essere utilizzato secondo le specifiche del fabbricatore e per nessun altro motivo o scopo.

●

Evitare di mettere in funzione l’apparecchio con le mani bagnate, questo potrebbe causare gravi danni.

●

Quando il condizionatore é in funzionamento con porta e finistre aperte (l’umidità della stanza é sempre superiore dell’ 80%) e con il deflettore dell’aria spostato verso il basso oppure automaticamente in movimento per lungo tempo, l’aqua si condensa sul deflettore dell’aria gocciolando di quando in quando, bagnando i mobili. Quindi evitare di farlo funzioneare in tali condizioni per un periodo prolungato.

●

Se il calore dell’ambiente è superiore alla portata di raffreddamento o riscaldamento del condizionatore (se, per esempio, un numero elevato di persone si trovano nella stanza, o se si utilizzano altre apparecchiature di riscaldamento ecc), non sarà possible raggiungere la temperatura ambiente impostata.

●

Questo apparecchio non è inteso ad uso dei bambini in giovane età o persone inferme a meno che siano adeguatamente sorvegliati da una persona responsabile per assicurarsi che usino l’apparecchio in modo sicuro.

●

I bambini in giovane età dovrebbero essere sorvegliati per accertarsi che non giochino con l’apparecchio.

●

Evitare di salire sull’unità esterna e di appoggiare oggetti di ogni tipo.

●

Non spostare il flusso d’aria fredda del condizionatore d’aria in direzione di elettrodomestici tipo forno, bollitore ecc, oppure verso impianti di riscaldamento ciò può influire sulla funzionalità di tali apparecchi.

●

Accertarsi che il telaio di supporto esterno sia fissato saldamente e senza difetti. In caso contrario l’unità esterna può crollare e provocare danni.

●

Evitare di spruzzare oppure gettare acqua direttamente sulla cassetta del condizionatore d’aria quando si pulisce, poichè ciò può provocare un corto circuito.

●

Evitare di esporre le piante direttamente al flusso d’aria, ciò le danneggerebbe.

●

Spegnere l’interruttore automatico se si prevede di non usare il condizionatore per un lungo periodo di tempo.

●

Non mettere contenitori d’acqua (tipo vasi da fiori) sull’apparecchio esterno, per evitare che l’acqua goccioli nella parte interna dell’unità. L’acqua gocciolando nella parte interna dell’unità danneggia l’isolatore e provoca un corto circuito.

●

Non usi alcuni spruzzi di capelli o dell’aerosol vicino all’unità dell’interno. Questo prodotto chimico può aderirsi sull’aletta dello scambiatore di calore ed ostruire il flusso dell’acqua di evaporazione per vuotare la vaschetta. L’acqua cadrà sul ventilatore tangenziale e causerà l’acqua che spruzza fuori dall’unità dell’interno.
