O

●

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

N

●

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

●

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

●

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 place plants directly under the air flow as it is bad for the plants.

●

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.

Non mettere contenitori d’acqua (tipo vasi da fiori) sull’apparecchio esterno,

ARRESTO

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.

●

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

●

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.

CONDIZIONATORE D’ARIA MULTI-AIR

Con questo condizionatore multi-air è possibile collegare diversi apparecchi interni a una unità esterna di comando. È possibile far funzionare il numero desiderato di apparecchi.

Combinazione di operazioni:

Quando il modo di funzionamento è selezionato:

● Non è possibile far funzionare gli apparecchi con

le seguenti combinazioni.

Una unità

Riscaldamento

Altra unità

Refrigerazione

Deumidificazione

Circolazione (ventilatore)

● L’apparecchio interno acceso per primo è in funzione, ma gli altri

apparecchi interni accesi in un secondo momento non sono in funzione mentre la spia luminosa è accesa.

● Per riavviare un apparecchio acceso in un secondo momento,

spegnere l’apparecchio acceso per primo o quello acceso in un secondo momento e selezionare nuovamente il tipo di operazione, quindi ripetere l’operazione.

Durante il funzionamento automatico:

● Quando il riscaldamento è selezionato automaticamente per la prima unità dell’interno, l’unità dell’interno seguente allora

comincia riscaldare. Inoltre, se raffreddandosi o dehumidifying è selezionato automaticamente per la prima unità dell’interno, l’unità dell’interno seguente inoltre cominci raffreddarsi o dehumidify.

Regolazione del numero di unità interne:

Diminuire il numero di apparecchi in funzione, specialmente quando fa molto caldo o molto freddo oppure quando si desidera raggiungere velocemente la temperatura stabilita.

Unità interne spente:

Quando un apparecchio interno opera in un ambiente in modalità refrigerazione, riscaldamento o deumidificazione, è possibile avvertire il rumore del flusso del refrigerante da un altro apparecchio oppure si può verificare che un apparecchio non funzionante si surriscaldi. Ciò avviene perché l’apparecchio convoglia il refrigerante all’unità esterna per essere pronto al funzionamento.
