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.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.
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 degraded if the outdoor temperature is high
DRY	Eliminates humidity while maintaining the indoor 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 indoor temperature and starts the operation.The system automatically reselects setting at a regular interval to bring the indoor temperature to the user-setting level.
FAN	This mode is valid for fan only.

• If the temperature does not reach the desired point, change the airflow rate setting.
• In DRY operation, the airflow rate setting is not variable.

NOTE

■ Note on the angles of the flaps

- The flaps swinging range depends on the operation. (See the figure.)

COOL, DRY and FAN operation Stop operation 30° Upper limit / COMFORT AIRFLOW 50° Lower limit

HEAT operation Stop operation 30° Upper limit 75° 70° Lower limit COMFORT AIRFLOW

■ Note on the angles of the flaps

- Using 3-D airflow circulates cold air, which tends to collect at the bottom of the room, and hot air, which tends to collect near the ceiling, throughout the room, preventing areas of cold and hot developing.

■ Notes on airflow rate setting

• At smaller airflow rates, the cooling (heating) effect is also smaller.
• If the air conditioner is operated in COOL or DRY operation with the flaps kept stopped in the downward direction, the flaps will automatically start operating in approximately an hour in order to prevent dew condensation.

CAUTION

• Always use a remote controller to adjust the angles of the flaps and louvres.
- If you attempt to move the flaps and louvres forcibly by hand when they are swinging, the mechanism may be damaged.
- Inside the air outlet, a fan is rotating at a high speed.

COMFORT AIRFLOW / INTELLIGENT EYE Operation

COMFORT AIRFLOW operation

Notes on COMFORT AIRFLOW operation ■

- The position of the flaps will change, preventing air from blowing directly on the occupants of the room.

POWERFUL operation and COMFORT AIRFLOW operation cannot be used at the same time.

Priority is given to the function of whichever button is pressed last.

- The airflow rate will be set to AUTO. If the up and down airflow direction is selected, COMFORT AIRFLOW operation will be cancelled.

Notes on INTELLIGENT EYE operation ■

Application range is as follows.

Vertical angle 90° (Side view)

Horizontal angle 110° (Top view)

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

If no people are detected in either area 1 or 2 for 20 minutes, the air conditioner switches to the energy-saving mode with the set temperature shifted by 2^ C.

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

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

- The airflow direction from the louvres will be leftward if there are people in both areas 1 and 2. The air will also flow left if there is a person right in front of the sensor as the sensor judges that there are people in both areas.

- Due to the position of the sensor, people might be exposed to the airflow 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. Using both modes together, the air conditioner will not direct the airflow towards the people.

The sensor may not detect moving objects further than 7m away. (Please see the application range.)

• Sensor detection sensitivity changes according to the indoor unit location, the speed of passers-by, temperature range, etc.
• The sensor could also mistakenly detect pets, sunlight, fluttering curtains and light reflected off of mirrors as passers-by.
• INTELLIGENT EYE operation will not switch on during POWERFUL operation.
• NIGHT SET mode ▶Page 21 will not switch on during use of INTELLIGENT EYE operation.

■ Notes on combining COMFORT AIRFLOW operation and INTELLIGENT EYE operation

• The airflow rate will be set to AUTO. If the up and down airflow direction is selected, COMFORT AIRFLOW operation will be canceled. Priority is given to the function of whichever button is pressed last.
• When the INTELLIGENT EYE sensor detects the movement of people, it adjusts the airflow direction upward (while in COOL operation) and downward (while in HEAT operation), by adjusting the flaps. When the sensor detects people, the louvres will direct the airflow in such a way that it will not be blown directly on them. If there are no people, the air conditioner will switch to energy-saving operation after 20 minutes.

CAUTION

• Do not place large objects near the INTELLIGENT EYE sensor.
  Also keep heating units and humidifiers 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.

- POWERFUL operation can only be set when the unit is running. Pressing ⏻ causes the settings to be cancelled, and “▼” disappears from the LCD.

- POWERFUL operation will not increase the capacity of the air conditioner if the air conditioner is already in operation with its maximum capacity demonstrated.

• In COOL and HEAT operation

To maximize the cooling (heating) effect, the capacity of outdoor unit increases and the airflow rate becomes fixed at the maximum setting. The temperature and airflow settings cannot be changed.

• In DRY operation

The temperature setting is lowered by 2.5^ C and the airflow rate is slightly increased.

- In FAN operation

The airflow rate is fixed at the maximum setting.

• In AUTO operation

To maximize the cooling (heating) effect, the capacity of outdoor unit is increased and the airflow rate is fixed to the maximum setting.

ECONO / OUTDOOR UNIT QUIET Operation

ECONO operation

ECONO operation is a function which enables efficient operation by limiting the maximum power consumption value.

This function is useful to prevent the circuit breaker from tripping when the unit operates alongside other appliances on the same circuit.

[Example]

Normal operation ECONO operation

Illustration of household appliances including a washing machine, vacuum cleaner, and washing machine (no text or symbols)

In case the air conditioner and other appliances which require high power consumption are used at the same time, a circuit breaker may trip if the air conditioner operates with its maximum capacity.

Illustration of a kitchen appliance with a worker, a vacuum cleaner, and a hairdryer (no text or symbols)

- The maximum power consumption of the air conditioner is limited by using ECONO operation. The circuit breaker will hardly trip even if the air conditioner and other appliances are used at same time.

OUTDOOR UNIT QUIET operation ■

OUTDOOR UNIT QUIET operation lowers the noise level of the outdoor unit by changing the frequency and fan speed of the outdoor unit. This function is convenient during the night-time operation.

[Example] Using the OUTDOOR UNIT QUIET operation during the night.

Illustration of a night scene with two houses, a bed, a child at a desk, and a dog under a blanket (no text or symbols)

The noise level of the • outdoor unit will be lower. This function is useful when you need to consider the noise for your neighbourhood.

Notes on ECONO operation ■

• ECONO operation can only be set when the unit is running. Pressing ⏻ causes the settings to be cancelled, and “” disappears from the LCD.
• ECONO operation is a function which enables efficient operation by limiting the power consumption of the outdoor unit (operating frequency). ECONO operation functions in AUTO, COOL, DRY, and HEAT operation.

POWERFUL and ECONO operation cannot be used at the same time.

Priority is given to the function of whichever button is pressed last.

- If the power consumption level is already low, switching to ECONO operation will not reduce the power consumption.

Notes on OUTDOOR UNIT QUIET operation

• This function is available in COOL, HEAT, and AUTO operation. This is not available in FAN and DRY operation.
• POWERFUL operation and OUTDOOR UNIT QUIET operation cannot be used at the same time. Priority is given to the function of whichever button is pressed last.
• Even if the operation is stopped by using the remote controller or the indoor unit ON/OFF switch when using OUTDOOR UNIT QUIET operation, "💡" will remain lit on the remote controller display.
• OUTDOOR UNIT QUIET operation will not reduce the frequency nor fan speed if they already are operating at reduced levels.
• This operation is performed with lower power and therefore may not provide a sufficient cooling (heating) effect.

• For specialist maintenance, please contact the dealer where you bought the air conditioner.
• The maintenance cost must be borne by the 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 fl aps do not start swinging immediately.

The air conditioner is adjusting the position of the • flaps. The flaps 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 cool airflow. Operation will resume automatically when the indoor temperature falls.

Operation does not start soon.

When 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.

HEAT operation stops suddenly and a flowing sound is heard.

The outdoor unit is defrosting. HEAT operation starts after the frost on the outdoor unit has been removed. This can take about 4 to 12 minutes.

Diagram of a car air conditioner unit with a cooling fan and cooling fins (no text or labels)

Different sounds are heard.

■A sound like flowing 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 during COOL or DRY 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.

■owing sound

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

Ticking sound

- This sound is generated when the cabinet and frame of the air conditioner slightly expand or shrink 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.

Outdoor unit

The outdoor unit emits water or steam.

■HEAT operation

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

COOL or DRY operation

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