Note

To learn more...

Operation mode

AUTO : During operation mode selection the POWER indicator blinks.

COOL : Provides efficient comfort cooling to suit your needs.

DRY : Unit operates at low fan speed to give a gentle cooling operation.

Energy saving temperature setting

Operating the unit within the recommended temperature range may save energy.

COOL : 26.0 °C \~ 28.0 °C / 79 °F \~ 82 °F.

Air flow direction

In COOL/DRY mode:

If AUTO is set, the flap swings left/right and up/down automatically.

Auto restart control

If power is resumed after a power failure, the operation will restart automatically after a period of time with 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 turned off.

To remove the moisture left in the internal parts, the fan will operate for 30 minutes with flap opened slightly. This process only applicable when the unit is operated in COOL/DRY mode before turned off. Then, nanoe-G deactivates viruses/bacteria on the filter for 2 hours with fan stopped and flap closed.

Do not turn off the power supply during this operation. After power failure, this operation will not resume.

ECONAVI and AUTO COMFORT

■ Econavi with intelligent eco sensors

Intelligent eco sensors detect potential waste of energy using the human activity sensor and sunlight sensor.

■ Auto Comfort with intelligent eco sensors

Intelligent eco sensors detect potential waste of energy using the human activity sensor and auto adjust the temperature and fan speed during high activity level to provide comfort environment.

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 source of heat, such as pets, or may not detect the human activity or source of heat if the person stays motionless.
• Do not place large objects near the sensor and keep away heating units or humidifier from the sensor's detections area.

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

5 Features

① Temperature wave

Rhythmic temperature-controlled pattern to save energy without sacrificing comfort.

②Area search

③ Activity detection

④ Absence detection

Human activity sensor detects presence/absence of human beings and the movement speed of human activities minimising the required amount of energy.

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 15 minutes) before the actual set time in order to achieve the desired temperature on time.
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 automatic fan speed setting.	This helps to remove the surrounding odour.
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.
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.
Dust may have collected around the front panel, grilles and wall surrounding the unit after extended use.	The dust accumulation is due to air purification effect of negative ions from nanoe-G. Remove the dust regularly with a clean dampened cloth.

Check the following before calling for servicing.

Symptom Check
Operation in COOL mode is not working efficiently.	Set the temperature correctly.Close all doors and windows.Clean or replace the filters.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 signal transmitter. Please consult authorised dealer.

Troubleshooting

When...

■ The remote control is missing or a malfunction has occurred

1. Raise the front panel.
2. Press the button once to use in AUTO mode.
3. Press and hold the button until you hear 1 beep, then release to use in forced COOL mode.
4. 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 operation. After 15 minutes of operation, it is normal to have the following temperature difference between the air inlet and outlet vents:
  COOL: ≥ 8 °C / 14.4 °F

■ The units are not going to be used for a long period of time

• Activate nanoe-G operation for 2\~3 hours as an alternative 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.
