nanoe ™ X Filter Deactivation
Depending on the unit’s accumulated operation time, the nanoe ™ X may be activated only once a day after the unit is turned off standby mode. During the nanoe ™ X filter deactivation operation, the flap will open slightly with low fan speed operation for 2.5 hours if the unit was in COOL / DRY mode, and 2 hours if the unit was in nanoe™ TECHNOLOGY, before the unit is turned off. This is to remove viruses / bacteria from the surroundings. The filter deactivation operation is complete when the fan stops and the flap closes. Do not turn off the power supply during this operation. After a power failure, this operation will not resume.

Cleaning the Air Conditioner

Cleaning has to be carried out at regular intervals to ensure the unit is at optimal performance. A dirty unit may cause malfunction and you may retrieve “H 99” error code. Consult an authorised dealer.

  • Before cleaning, switch off the power supply and unplug the unit.
  • Do not touch the aluminium fin as the sharp parts may cause injury.
  • Do not use benzine, thinner or scouring powder.
  • Use soap ( pH 7) or neutral household detergent only.
  • Do not use water hotter than 40 °C / 104 °F.

Indoor Unit
Wipe the unit gently with a soft and dry cloth. The coils and fans should be cleaned periodically by an authorised dealer.
Outdoor Unit
Clean the debris that surround the unit. Clear any blockage from the drain pipe.

nanoeTM-G Generator
Once every 2 Weeks

  • Clean with dry cotton bud.
  • Do not touch during operation.

Air Filters
Once every 2 Weeks

  • Wash / Rinse the filters gently with water to avoid damaging the surface.
  • Dry the filters thoroughly under a shade, away from fi re or direct sunlight.
  • Replace any damaged filters.

Troubleshooting

The following symptoms do not indicate malfunction.

Symptom Cause
POWER indicator blinks before the unit is switched on. • This is the preliminary step to prepare for the TIMER operation after it has been set.

When Timer is set ON, the unit may start earlier up to 15 minutes (1 Cooling model) / 30 minutes (2 Heatpump model) before the actual set time to achieve the desired

temperature on time.

TIMER indicator is always ON. • When Timer has been set, the Timer setting repeats daily.
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 is to help 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 in temperature caused the unit to expand and contract.
Water flowing sound during operation. • Refrigerant flow inside the unit.
Mist emerges from indoor unit. • During cooling operation, the discharged cold air may condense to water vapour.
Outdoor unit emits water or steam. • During cooling operation, condensation occurs on

cold pipes and the condensed water may drip from the outdoor unit.

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 subjected to the types of materials used in plastic parts. It is accelerated when exposed to heat, sun light, UV light or environmental factors.
After extended use, dust may cover the front panel, grilles and the wall surrounding the unit. • The dust accumulation is due to the air purification effect of negative ions from nanoe™-G. Remove the dust regularly with a clean dampened cloth.
Soft buzzing sound from indoor unit during nanoe™ TECHNOLOGY operation. • It is normal when the nanoe™X generator is working. If you are concerned about the sound, cancel the nanoe™ TECHNOLOGY operation.
Wireless LAN indicator is ON when the unit is OFF. • The unit’s wireless LAN connection with the router has been activated.

Check the following before calling for servicing.

Symptom Check
Operation in HEAT (*2 Heatpump model) / 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 the signal transmitter. Consult an authorised dealer.

The nanoe™ TECHNOLOGY indicator at the indoor unit is not ON when nanoe™ TECHNOLOGY is activated. • Use the remote control to retrieve the error code and consult an authorised dealer.

Troubleshooting
When..
The remote control is missing or a malfunction has occurred

  1. Cooling Model
    • Raise the front panel.
    • Press AUTO OFF / ON once to use in iAUTO-X mode.
    • Press AUTO OFF / ON until you hear 1 beep, then release to use in forced COOL mode.
    • Press AUTO OFF/ON again to turn off the unit.
  2. Heat pump Model
    • Raise the front panel.
    • Press AUTO OFF / ON once to use in AUTO mode.
  3. Press AUTO OFF / ON until you hear 1 beep, then release to use inforced COOL mode.
  4. Press AUTO OFF / ON until you hear 2 beeps, then release to use in forced HEAT mode.
  5. Press AUTO OFF / ON again to turn off the unit.

The Indicators are Too Bright
To dim or restore the indicators’ brightness on the unit, press on the remote for 5 seconds.
Conducting a Seasonal Inspection after Extended Period of Non-Use

  • Check the batteries.
  • Check that there is no obstruction around the air inlets and outlet vents.
  • Use AUTO OFF / ON on the unit to select HEAT (Heat pump model) / COOL mode. For details, refer “The remote control is missing or a malfunction has occurred” above. After 15 minutes of operation, it is normal to have the following temperature difference between the air inlet and outlet vents:
    • HEAT (Heat pump model) : ≥ 14 °C / 25.2 °F
    • COOL : ≥ 8 °C / 14.4 °F

The Units will be not used for an Extended Period

  • Activate nanoe ™ TECHNOLOGY mode for 2~3 hours to remove any moisture left in the internal parts thoroughly. This is to prevent mould growth.
  • Turn off the power supply and unplug the unit.
  • Remove the batteries from the remote control.

NON SERVICEABLE CRITERIAS
TURN OFF THE POWER SUPPLY AND UNPLUG THE UNIT. Then consult an authorised dealer in the following conditions :

  • Abnormal noise during operation.
  • Water / Foreign particles have entered the remote control.
  • Water is leaking from the indoor unit.
  • The circuit breaker switches off frequently.
  • The power cord becomes unnaturally warm.
  • The switches or buttons are not functioning properly.
