This is not good for the health
and wastes electricity.
Keep blinds or curtains
closed.
Do not let direct sunshine
enter the room when the air
conditioner is in operation.
Keep the room temperature
uniform.
Adjust the vertical and
horizontal airflow direction to
ensure a uniform temperature
in the room.
Make sure that the doors
and windows are shut tight.
Avoid opening doors and
windows as much as possible
to keep the cool air in the
room.
Clean the air filter regularly.
Blockages in the air filter
reduce the airflow and lower
cooling and dehumidifying
effects. Clean at least once
every two weeks.
Ventilate the room
occasionally.
Since windows are kept
closed, it is a good idea to
open them and ventilate the
room now and then.

furniture or cloth
items in the room.
• Condensation occurs
when the airflow from
the air conditioner
cools the warm room
air.
• This is the protector
of the mechanism.
• Wait about three
minutes and
operation will begin.
The air conditioner
does not operate.
The room has a

Prima di iniziare
6 Unità Interna
Prima di iniziare
1. Per lʼinstallazione rivolgersi a un tecnico specializzato.
2. Utilizzare un circuito dedicato.
1. Lʼesposizione al flusso diretto dellʼaria per un periodo prolungato di tempo può essere pericoloso
per la salute.
Non esporre le persone, gli animali o le piante al flusso d'aria per periodi di tempo prolungati.
2. A causa di una possibile carenza di ossigeno, ventilare la stanza quando viene usato insieme a
stufe o altri dispositivi di riscaldamento.
3. Non usare questo condizionatore dʼaria per scopi speciali non specificati (es. per conservare
strumenti di precisione, cibo, animali, piante o oggetti dʼarte.) Questo tipo di uso può rovinare
questo tipo di oggetti.
1. Quando si rimuove il filtro non toccare mai gli elementi metallici dellʼunità. Si possono procurare
lesioni quando si maneggiano i bordi affilati di metallo.
2. Non pulire lʼinterno del condizionatore dʼaria con acqua. Lʼesposizione allʼacqua può rovinare
lʼisolamento e provocare di conseguenza scosse elettriche.
3. Durante la pulizia del prodotto assicurarsi che lʼinterruttore automatico e lʼalimentazione siano
disattivati. Durante il funzionamento la ventola gira a velocità elevata. Esiste la possibilità di
provocare lesioni se lʼunità viene accidentalmente accesa mentre si puliscono i componenti interni
dellʼapparecchio.
Per le riparazioni e la manutenzione rivolgersi al proprio rivenditore autorizzato.
