• Do not cool excessively indoors. This may be harmful for your health and may consume more

• Block sunlight with blinds or curtains while you are operating the air conditioner.

• Keep doors or windows closed tightly while you are operating the air conditioner.

• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

• Speed up the fan to cool or warm indoor air quickly, in a short period of time.

• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air con-

BEFORE USE

About the system

This system of air conditioner can be used for heating/cooling applications.

Preparing for operation

• Contact an installation specialist for installation.

• Use a dedicated circuit.

Usage

• Being exposed to direct airﬂow for an extended period of time could be hazardous to your health. Do

not expose occupants, pets, or plants to direct airﬂow for extended periods of time.

• Due to the possibility of oxygen deﬁciency, ventilate the room when used together with stoves or

other heating devices.

• Do not use this air conditioner for non-speciﬁed special purposes (e.g. preserving precision devices,

food, pets, plants, and art objects). Such usage could damage the items.

Cleaning and maintenance

• Do not touch the metal parts of the unit when removing the ﬁlter. Injuries can occur when handling

sharp metal edges.

• Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation,

leading to possible electric shock.

• When cleaning the unit, ﬁrst make sure that the power and breaker are turned off. The fan rotates at a

very high speed during operation. There is a possibility of injury if the unit’s power is accidentally triggered on while cleaning inner parts of the unit.

ENGLISH

Service

For repair and maintenance, contact your authorized service dealer.

Disposal

The unit uses hydroﬂuorocarbon. Contact your dealer when discarding this unit. It is required by law to collect, transport and discard the refrigerant in accordance with the “hydroﬂuorocarbon collection and destruction”

regulations.

Air Filters

The air ﬁlters behind the front grille should be checked and cleaned once every 2 weeks or more often if necessary.

- Never use any of the followings: Water hotter than 40°C.

Could cause deformation and or discoloration.

Volatile substances. Could damage the surfaces of the air conditioner.

- Remove the Air ﬁlters.

Take hold of the tab and pull slightly forward to remove the ﬁlter.

CAUTION

When the air filter is to be removed, do not touch the metal parts of the indoor unit. It may cause an injury.

- Clean dirt from the air ﬁlter using a vacuum

cleaner or washing with water.

If dirt is conspicuous, wash with a neutral detergent in lukewarm water.

If hot water (40°C or more) is used, it may be deformed.

- After washing with water, dry well in the

shade.

Operation Tips!

MAINTENANCE AND SERVICE

ENGLISH

This is not good for the health and wastes electricity.

Avoid opening doors and windows as much as possible to keep the cool air in the room.

Do not let direct sunshine enter the room when the air conditioner is in operation.

Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks.

When the air conditioner is not

going....

When air conditioner is not going to be used for a long time.

Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room.

Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.

Helpful information

The air ﬁlters and your electric bill. If the air ﬁlters become clogged with dust, the

cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted.

- Operate the air conditioner at the following

settings for 2 to 3 hours.

Type of operation: Fan operation mode. (Refer to page “Fan Mode”.)

This will dry out the internal mechanisms.

- Turn off the breaker.

CAUTION

Turn off the breaker when the air conditioner is not going to be used for a long time. Dirt may collect and may cause a fire.

- Remove the batteries from the Remote Con-

troller.

When the air conditioner is to be used again.

- Clean the air ﬁlter and install it in the indoor

unit. (Refer to page “MAINTENANCE AND SERVICE”.)

- Check that the air inlet and outlet of the in-

door/outdoor unit are not blocked.

- Check that the ground wire is connected cor-

rectly. It may be connect to the indoor unit side.

ENGLISH

User must carry routine checkup & cleaning to avoid unit’s poor performance. In case of special situation, the job must be carried out by service person only.

The air conditioner does not operate.

The room has a peculiar odor.

It seems that condensation is leaking from the air conditioner.

Air conditioner does not operate for about 3 minutes when restart.

Does not cool or heat effectively.

The air conditioner operation is noisy.

Crack sound is heard.

Remote control display is faint, or no display at all.

Filter sign lamp (LED) is ON.

Troubleshooting Tips! Save time and money!

Check the following points before requesting repairs or service.... If the malfunction persist,

please contact your dealer.

MAINTENANCE AND SERVICE

- Have you made a mistake in timer operation?

- Has the fuse blown or has the circuit breaker been tripped?

- Is the air filter dirty? See air filter cleaning instructions.

- The room may have been very hot when the room air conditioner was first turned on. Allow time for it to cool down.

- Has the temperature been set incorrectly?

- Are the indoor unit's air inlet or outlet vents obstructed?

- Check that this is not a damp smell exuded by the walls, carpet, furniture or cloth items in the room.

- For a noise that sounds like water flowing.

* This is the sound

of freon flowing inside the air conditioner unit.

- For a noise that sounds like the compressed air releasing into atmosphere.

This is the sound of the dehumidifying water being processed inside the air conditioning unit.

- Condensation occurs when the airflow from the air conditioner cools the warm room air.

- This sound is generated by the expansion/ constriction of the front panel, etc. due to changes of temperature.

- Cleaning the filter, press the Timer button and ◀ button of wired remote controller at the same time for 3 sec.

- This is the protector of the mechanism.

- Wait about three minutes and operation will begin.

- Are the batteries depleted?

- Are the batteries inserted in the opposite (+) and (-) directions?

Call the service immediately in the following situations

- Anything abnormal such as burning smell, loud noise etc. happen. Stop the unit and turn the breaker off. Never try to repair by yourself or restart the system in such cases.

- Main power cord is too hot or damaged.

- Error code is generated by self diagnosis.

- Water leaks from indoor unit even if the humidity is low.

- Any switch, breaker (safety, earth) or fuse fails to work properly

CONSIGLI PER IL RISPARMIO DI ENERGIA

ITALIANO

• Non raffreddare eccessivamente gli ambienti interni. Questo può essere dannoso per la salute e può consumare maggiore quantità di elettricità.

• Boccate la luce solare con schermi o tende mentre usate il condizionatore d'aria.

• Tenete le porte e le finestre chiuse quando usate il condizionatore.

•

Regolare la direzione del flusso d'aria verticalmente o orizzontalmente per far circolare l'aria interna.

• Accelerare la ventilatore per raffreddare o riscaldare l'aria interna rapidamente in un breve periodo di tempo.

• Aprire le finestra regolarmente per la ventilazione quando la qualità dell'aria interna può deteriorarsi se il condizionatore viene usato per molte ore.

• Pulire il filtro aria una volta ogni 2 settimane. La polvere e le impurità raccolte nel filtro dell'aria possono bloccare il flusso dell'aria o ridurre le funzioni di raffreddamento/deumidificazione.
