Note:


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
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.
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.
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.
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 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.
The sunlight sensor detects changes in sunlight intensity in the room. It reduces the waste of energy under fewer sunlight conditions.

To ensure optimal performance of the unit, cleaning has to be carried out at regular intervals. Dirty unit may cause malfunction and you may see nanoe-G indicator blinks or error code “H99”. Please consult authorised dealer.
Indoor unit
Wipe the unit gently with a soft, dry cloth. Coils and fans should be cleaned for at least every 6 months by an authorized dealer.
Human activity sensor Do not hit or violently press or poke it with a sharp object. This can lead to damage and malfunction.

Outdoor unit
Clear debris that surround the unit. Clear any blockage from drain pipe.

Front panel
Wash gently and dry.
Remove the front panel

Close it securely

Indoor unit

nanoe-G Generator
Once every 2 weeks

Air filters
Once every 2 weeks

Remove air filter

Attach air filter

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. |
