Preparation before Operation

Turn the breaker on

•After the power is turned on, the flap of the indoor unit opens and closes once to set the reference position.

NOTE

Tips for saving energy

•Be careful not to cool (heat) the room too much. Keeping the temperature setting at a moderate level helps save energy.

•Cover windows with a blind or a curtain.

Blocking sunlight and air from outdoors increases the cooling (heating) effect.

Recommended temperature setting

For cooling: 26-28°C

For heating: 20-24°C

•Clogged air filters cause inefficient operation and waste energy. Clean them once in about every 2 weeks.

Please note

•The air conditioner always consumes 15-35W of electricity even while it is not operating.

•If you are not going to use the air conditioner for a long period, for example in spring or autumn, turn the breaker off.

•Use the air conditioner in the following conditions.

Mode	Operating conditions	If operation is continued out of this range
COOL	Outdoor temperature: 10-46°C	• A safety device may work to stop the operation.
	Indoor temperature: 18-32°C	• Condensation may occur on the indoor unit and drip.
	Indoor humidity: 80% max.
HEAT	Outdoor temperature: –15-24°C	• A safety device may work to stop the operation.
	Indoor temperature: 10-30°C
DRY	Outdoor temperature: 10-46°C	• A safety device may work to stop the operation.
	Indoor temperature: 18-32°C	• Condensation may occur on the indoor unit and drip.
	Indoor humidity: 80% max.

•Operation outside this humidity or temperature range may cause a safety device to disable the system.

•Indoor unit quiet operation

When the airflow is set to “ ”, the noise from the indoor unit will become quieter. Use this when making the noise quieter.

NOTE

Notes on HEAT operation

•Since this air conditioner heats the room by taking heat from outdoor air to indoors, the heating capacity becomes smaller in lower outdoor temperatures. If the heating effect is insufficient, it is recommended to use another heating appliance in combination with the air conditioner.

•The heat pump system heats the room by circulating hot air around all parts of the room. After the start of HEAT operation, it takes some time before the room gets warmer.

•In HEAT operation, frost may occur on the outdoor unit and lower the heating capacity. In that case, the system switches into defrosting operation to take away the frost.

•During defrosting operation, hot air does not flow out of indoor unit.

•A pinging sound may be heard during defrosting operation, which, however does not mean that the air conditioner has failures.

Note on COOL operation

•This air conditioner cools the room by releasing the heat in the room outside.

Therefore, the cooling performance of the air conditioner may be degraded if the outdoor temperature is high.

Note on DRY operation

•The computer chip works to rid the room of humidity while maintaining the temperature as much as possible. It automatically controls temperature and airflow rate, so manual adjustment of these functions is unavailable.

Notes on AUTO operation

•In AUTO operation, the system selects an appropriate operation mode (COOL or HEAT) based on the room and outside temperatures and starts the operation.

•The system automatically reselects setting at a regular interval to bring the room temperature to user-setting level.

Note on FAN operation

•This mode is valid for fan only.

Note on airflow rate setting

•At smaller airflow rates, the cooling (heating) effect is also smaller.

Adjusting the Airflow Direction

To adjust the louvers (vertical blades)

Hold the knob and move the louvers.

(You will find a knob on the left-side and the right-side blades.)

•When the unit is installed in the corner of a room, the direction of the louvers should be facing away from the wall.

If they face the wall, the wall will block off the wind, causing the cooling (or heating) efficiency to drop.

CAUTION

•Always use a remote controller to adjust the angles of the flap. If you attempt to move the flap and louvers forcibly with hand when they are swinging, the mechanism may be broken.

•Be careful when adjusting the louvers. Inside the air outlet, a fan is rotating at a high speed.

NOTE

Notes on the angles of the flap

•The flap swinging range depends on the operation. (See the figure.)

•If the air conditioner is operated in HEAT or DRY operation with the flap kept stopped in the downward direction, the flap will automatically start operating in approxmately an hour in order to prevent dew condensation.

Check

• Please check again before calling a repair person.

The flap does not start swing immediately.

•The air conditioner is adjusting the flap position. The flap will start moving soon.

The HEAT operation stops suddenly and a flowing sound is heard.

•The outdoor unit is taking away the frost. The HEAT operation starts after the frost on the outdoor unit is removed. You should wait for about 4 to 12 minutes.

Operation does not start soon.

When “ON/OFF” button was pressed soon after operation was stopped.

When the mode was reselected.

•This is to protect the air conditioner. You should wait for about 3 minutes.

A sound is heard.

A sound like a flow of water

•This sound is generated because the refrigerant in the air conditioner is flowing.

•This is a pumping sound of the water in the air conditioner it is heard when the water is pumped out from the air conditioner in cooling or drying operation.

•The refrigerant flows in the air conditioner even if the air conditioner is not working when the indoor units in other rooms are in operation.

Blowing sound

•This sound is generated when the flow of the refrigerant in the air conditioner is switched over.

Pinging sound

•This sound is generated when the size of the air conditioner slightly expands or shrinks as a result of temperature changes.

Clicking sound during operation or idle time

•This sound is generated when the refrigerant control valves or the electrical parts operate.

Clopping sound

•This sound is heard from the inside of the air conditioner when the exhaust fan is activated while the room doors are closed. Open the window or turn off the exhaust fan.
