How to use
To adjust airflow direction ow direction
• Do not adjust the flap by hand.
To adjust fan speed
• For AUTO, the indoor fan speed is automatically adjusted according to the operation mode.
• If i AUTO-X mode is set, fan speed is fixed to AUTO. To adjust fan speed, cancel i AUTO-X mode.
To switch between powerful/quiet
POWERFUL:
To reach the preset temperature quickly
• This operation stops automatically after 4 hours
QUIET:
To enjoy quiet operation
• This operation reduces airfl ow noise.
To improve humidity and moisture level
• This operation reduces air dryness and provides you with a comfortable living environment during COOL mode only.

Operation mode
AUTO :
During operation mode selection the POWER indicator blinks.
• Unit selects operation mode every 10 minutes according to setting temperature and room temperature.
HEAT :
Unit takes a while to warm up. The POWER indicator blinks during this operation.
COOL :
Provides efficient comfort cooling to suit your needs.
DRY :
Unit operates at low fan speed to give a gentle cooling operation.
FAN :
To circulate air in the room.
i AUTO-X :
The fast cooling is ideal when you come home on a hot day
Energy saving temperature setting
Operating the unit within the recommended temperature range may save energy.
HEAT : 20.0 °C ~ 24.0 °C / 68 °F ~ 75 °F. COOL : 26.0 °C ~ 28.0 °C / 79 °F ~ 82 °F.
Airflow direction
In COOL/DRY mode: If AUTO is set, the flaps swings left/right and up/down automatically.
In i AUTO-X mode: If AUTO is set, the horizontal fl ap is fixed at the lower position and shift to the upper position after reaching the set temperature, and the vertical fl ap swing according to activity detection. If the manual is set, the horizontal fl ap and vertical fl ap are fixed at the predetermined position.
In HEAT mode: If AUTO is set, the horizontal flap is fixed at the predetermined position. The vertical flap swings left/right after the temperature rises.
Auto restart control
If power is resumed after a power failure, the operation will restart automatically after a period of time with the previous operation mode and airflow direction.
• This control is not applicable when TIMER is set.
nanoe-G in-filter deactivation
Depending on the unit’s accumulated operation time, nanoe-G in-filter deactivation may activate only once a day after the unit is turned off. To remove the moisture left in the internal parts, the fan will operate for 30 minutes with the flap opened slightly. This process is only applicable when the unit is operated in COOL/DRY mode before being turned off. Then, nanoe-G deactivates viruses/bacteria on the filter for 2 hours with the fan stopped and flap closed. Do not turn off the power supply during this operation. After a power failure, this operation will not resume
ECONAVI
- Econavi with intelligent eco sensors
Intelligent eco sensors detect potential waste of energy using the human activity sensor and sunlight sensor.
The human activity sensor scans areas of heat source and movement in a room.
• Based on area activeness, flap will adjust its position automatically.
• The human activity sensor is influenced by the location of the indoor unit, the movement speed of human/non-human activity, temperature range, etc.
• The human activity sensor may mistakenly detect non-human activity and sources of heat, such as pets, or may not detect the human activity or sources of heat if the person stays motionless.
• Do not place large objects near the sensor and keep away heating units or humidifiers er from the sensor’s detections area.
The sunlight sensor detects changes in sunlight intensity in the room. It reduces the waste of energy under fewer sunlight conditions.
5 Features
1.Temperature wave
Rhythmic temperature-controlled pattern to save energy without sacrificing comfort.
2. Area search
3. Activity detection
4. Absence detection
5 Sunlight detection
Operating conditions
Use this air conditioner in the temperature range indicated in the table.
DBT: Dry bulb temperature, WBT: Wet bulb temperature
Cleaning instructions

Troubleshooting
The following symptoms do not indicate malfunction
Symptom | Cause |
| POWER indicator blinks before the unit is switched on | • This is a preliminary step in preparation for the operation when the ON timer has been set. • When ON Timer is set, the unit may start earlier (up to 35 minutes) before the actual set time in order to achieve the desired temperature on time. |
| POWER indicator blinks during HEAT mode with no warm air supply (and flap is closed). | • The unit is in defrost mode (and AIR SWING is set to AUTO). |
| TIMER indicator is always on. | • The timer setting repeats daily once set. |
| Operation is delayed a few minutes after restarting. | • The delay is a protection to the unit’s compressor. |
| Indoor fan stops occasionally during heating operation. | • To avoid unintended cooling effect |
| Indoor fan stops occasionally during automatic fan speed setting. | • This helps to remove the surrounding odour. |
| Airflow continues even after operation has stopped. | • Extraction of remaining heat from the indoor unit (maximum 30 seconds). |
| The room has a peculiar odour | • This may be due to damp smell emitted by the wall, carpet, furniture or clothing. |
| Cracking sound during operation | • Changes of temperature caused the expansion/ contraction of the unit. |
| Water flowing sound during operation. | • Refrigerant flow inside the unit |
| Mist emerges from indoor unit. | • Condensation effect due to cooling process. |
| Outdoor unit emits water/steam. | • Condensation or evaporation occurs on pipes. |
| Louder noise at outdoor unit during early operation of i AUTO-X. | • The compressor and fan rotate at higher speed to boost cooling performance during initial operation. |
| Discoloration of some plastic parts. | • Discoloration is subject to material types used in plastic parts, accelerated when exposed to heat, sun light, UV light or environmental factor. |
Check the following before calling for servicing.
Symptom | Check |
| Operation in HEAT/COOL mode is not working efficiently | • Set the temperature correctly. • Close all doors and windows. • Clean or replace the fi lters. • Clear any obstruction at the air inlet and air outlet vents |
| Noisy during operation. | • Check if the unit has been installed at an incline. • Close the front panel properly. |
| Remote control does not work. (Display is dim or transmission signal is weak.) | • Insert the batteries correctly. • Replace weak batteries. |
| The unit does not work. | • Check if the circuit breaker is tripped. • Check if timers have been set. |
| The unit does not receive the signal from the remote control. | • Make sure the receiver is not obstructed. • Certain fluorescent lights may interfere with the signal transmitter. Please consult authorized dealer. |
When...
- The remote control is missing or a malfunction has occurred
1.Raise the front panel.
2.Press the button once to use in i AUTO-X mode.
3. Press and hold the button until you hear 1 beep, then release to use in forced COOL mode.
4. Repeat step 3. Press and hold the button until you hear 2 beeps, then release to use in forced HEAT mode.
5.Press the button again to turn off.
- The indicators are too bright
To dim or restore the unit’s indicator brightness, press 
and hold for 5 seconds.
- Conducting a seasonal inspection after extended non-use
• Check the remote control batteries.
• Check that there is no obstruction around the air inlet and outlet vents.
• Use Auto OFF/ON button to select COOL/HEAT operation. After 15 minutes of operation, it is normal to have the following temperature difference between the air inlet and outlet vents:
- The units are not going to be used for a long period of time
• Activate HEAT mode for 2~3 hours to remove moisture left in the internal parts thoroughly to prevent mould growth.
• Turn off the power supply and unplug.
• Remove the remote control batteries.
NON SERVICEABLE CRITERIAS
TURN OFF THE POWER SUPPLY AND UNPLUG then please consult an authorised dealer when in following conditions:
• Abnormal noise during operation.
• Water/foreign particles have entered the remote control.
• Water leaks from Indoor unit.
• Circuit breaker switches off frequently.
• Power cord becomes unnaturally warm.
• Switches or buttons are not functioning properly
How to retrieve error codes
If the unit stops and the TIMER indicator blinks, use the remote control to retrieve the error code
• For certain errors, you may restart the unit for limited operation if there are 4 beeps when operation starts.
* Some error codes may not be applicable to your model. Consult authorized dealer for clarification.
