Notes on each operation mode

• 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 insuffi cient, 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 fl ow out of indoor unit.

• 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

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

• 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.

• This mode is valid for fan only.

• While the air conditioner is in INTELLIGENT EYE operation, the louvers will adjust the airfl ow direction if there are people in the sensing areas of the INTELLIGENT EYE so that the leftward or rightward airfl ow will not be directed to the people.

If no people are detected in either area 1 or 2 in 20 minutes, the air conditioner will go into energy-saving mode with the set temperature shifted by 2°C.

The air conditioner may go into energy-saving operation even if there are people in the areas.

This may occur depending on the clothes the people are wearing if there are no movements of the people in the areas.

• The airfl ow direction from the louvers will be leftward if there are people in both areas 1 and 2 or if there is a person right in front of the sensors because the sensors on the both sides will detect the person.

• Due to the position of the sensor, people might be exposed to the airfl ow of the indoor unit if they are close to the front side of the indoor unit.

If there are people close to the front side of the indoor unit or in both areas, it is recommended to use the COMFORT AIRFLOW and

INTELLIGENT EYE operations simultaneously. When both of them are in use, the air conditioner will not direct the airfl ow towards the people.

• Sensor may not detect moving objects further than 7m away. (Check the application range.)

• Sensor detection sensitivity changes according to indoor unit location, the speed of passersby, temperature range, etc.

• The sensor also mistakenly detects pets, sunlight, fl uttering curtains and light refl ected off of mirrors as passersby.

• INTELLIGENT EYE operation will not go on during POWERFUL operation.

• NIGHT SET mode Page 22 will not go on during use of INTELLIGENT EYE operation.

■

Notes on combination of COMFORT AIRFLOW operation and INTELLIGENT EYE operation

• The airfl ow rate will be set to AUTO. If the upper and lower airfl ow direction is selected, the COMFORT AIRFLOW operation will be canceled.


• The fl aps adjust the airfl ow direction upward (while in COOL operation) and downward (while in HEAT operation), during which the sensors of the INTELLIGENT EYE are working to detect the movement of people. When the sensors detect people, the louvers will direct the airfl ow in such way that it will not be blown directly on them. If there are no people, the air conditioner will go into energy-saving operation after

20 minutes.

CAUTION

• Do not place large objects near the sensor.

Also keep heating units or humidifi ers outside the sensor’s detection area. This sensor can detect undesirable objects.

• Do not hit or violently push the INTELLIGENT EYE sensor. This can lead to damage and malfunction.

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 fl aps do not start swing immediately.

• The air conditioner is adjusting the fl aps position.

The fl aps will start moving soon.

The air conditioner stops generating airfl ow during operation.

• Once the set temperature is reached, the airfl ow rate is reduced and operation stopped in order to avoid generating cool airfl ow (during heating) or in order to keep the humidity from rising (during cooling).

Operation will resume automatically when the indoor temperature rises or falls.

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.

The HEAT operation stops suddenly and a fl owing 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.

A sound is heard.

■

A sound like a fl ow of water

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

• 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 fl ows 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 fl ow of the refrigerant in the air conditioner is switched over.

■

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 fl ows

■ 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.

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.

37

Troubleshooting

• Troubleshooting measures are classifi ed 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 a repair person.

Operation stopped suddenly.

(OPERATION lamp fl ashes.)

• Are the air fi lters clean?

Clean the air fi lters.

• Is there anything to block the air inlet or the outlet of the indoor and the outdoor units?

• Turn the bleaker off and take all obstacles away. Then turn it on again and try operating the air conditioner with the remote controller. If the lamp still fl ashes, call the service shop where you bought the air conditioner.

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?

• Is the timer setting correct?

Operation stopped suddenly.

(OPERATION lamp is on.)

• For system protection, the air conditioner may stop operating on a sudden large voltage fl uctuation. It automatically resumes operation in about 3 minutes.

Cooling (Heating) effect is poor.

• Are the air fi lters clean?

• Is there anything to block the air inlet or the outlet of the indoor and the outdoor units?

• Is the temperature setting appropriate?

• Are the windows and doors closed?

• Are the airfl ow rate and the airfl ow direction set appropriately?

Mist comes out of the indoor unit.

• This happens when the air in the room is cooled into mist by the cold airfl ow during COOL operation.

• This is because the air in the room is cooled by the heat exchanger and becomes mist during defrost operation.

An abnormal functioning happens

during operation.

• The air conditioner may malfunction with lightning or radio waves. Turn the breaker off, turn it on again and try operating the air conditioner with the remote controller.

38

Troubleshooting

Hot air does not fl ow out soon after the start of HEAT operation.

• The air conditioner is warming up. You should wait for

1 to 4 minutes. (The system is designed to start discharging air only after it has reached a certain temperature.)

The ON/OFF TIMER does not operate according to the settings.

• Check if the ON/OFF TIMER and the WEEKLY TIMER are set to the same time.

Change or deactivate the settings in the WEEKLY

TIMER.
