NOTE

MODE Notes on each operation mode
HEAT	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.
COOL	This air conditioner cools the room by releasing the heat in the room outside.Therefore, the cooling performance of the air conditioner may be decrease if the outdoor temperature is high.
DRY	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.
AUTO	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.
FAN ONLY	This mode is valid for fan only.

• For specialist maintenance, contact the service shop where you bought the air conditioner.
• The maintenance cost must be in responsible of user.

Troubleshooting

■ These cases are not troubles.

- The following cases are not air conditioner troubles but have some reasons. You may just continue using it.

Indoor unit

The flaps do not start swing immediately.

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

Line drawing of a modern air conditioner unit with no text or symbols

The air conditioner stops generating airflow during HEAT operation.

- Once the set temperature is reached, the airflow rate is reduced and operation stopped in order to avoid generating a cool airflow. Opeartion will resume automatically when the indoor temperature falls.

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 and 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 switching.

■ Ticking sound

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

■ Whistling sound

- This sound is generated when refrigerant flows during defrosting operation.

■ 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.

■ Rotating machinery causes sound

• Sound is heard when the vertical swing flaps and the horizontal swing flaps move.
• When the air conditioner is operating in a quiet environment and the airflow rate of the indoor unit is set to Quiet Mode or Low Mode, the motion of the swing flaps may cause sound.

Outdoor unit

The outdoor unit emits water or steam.

■In HEAT operation

The frost on the outdoor unit melts into water or steam when the air conditioner is in defrost operation.

■In COOL or DRY operation

- Moisture in the air condenses into water on the cool surface of outdoor unit piping and drips.

NOTE

MODE Notes on each operation mode
HEAT	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.
COOL	This air conditioner cools the room by releasing the heat in the room outside.Therefore, the cooling performance of the air conditioner may be decrease if the outdoor temperature is high.
DRY	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.
AUTO	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.
FAN ONLY	This mode is valid for fan only.

• For specialist maintenance, contact the service shop where you bought the air conditioner.
• The maintenance cost must be in responsible of user.

Troubleshooting

■ These cases are not troubles.

• The following cases are not air conditioner troubles but have some reasons. You may just continue using it.

Indoor unit

The flaps do not start swing immediately.

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

The air conditioner stops generating airflow during HEAT operation.

- Once the set temperature is reached, the airflow rate is reduced and operation stopped in order to avoid generating a cool airflow. Opeartion will resume automatically when the indoor temperature falls.

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.

Line drawing of a wall-mounted air conditioner unit (no text or symbols)

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 and 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 switching.

■ Ticking sound

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

■ Whistling sound

- This sound is generated when refrigerant flows during defrosting operation.

■ 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.

■ Rotating machinery causes sound

• Sound is heard when the vertical swing flaps and the horizontal swing flaps move.
• When the air conditioner is operating in a quiet environment and the airflow rate of the indoor unit is set to Quiet Mode or Low Mode, the motion of the swing flaps may cause sound.

Outdoor unit

The outdoor unit emits water or steam.

In HEAT operation

The frost on the outdoor unit melts into water or steam when the air conditioner is in defrost operation.

■In COOL or DRY operation

- Moisture in the air condenses into water on the cool surface of outdoor unit piping and drips.

* The appearance of the outdoor unit may differ from some models.

- Troubleshooting measures are classified into the following two types on a remedial basis. Take an appropriate measure according to the symptom.

Not trouble

• These cases are not troubles.

Check

- Please check again before calling service shop.

The air conditioner does not operate.

(OPERATION lamp is off.)

• Hasn't a breaker turned off or a fuse blown?
• Isn't it a power failure?
• Are batteries set in the remote controller?
