Troubleshooting

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 35 minutes) before the actual set time 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 has been set to AUTO).
POWER indicator blinks, then stops blinking during COOL/DRY mode.| The system has been locked to operate in HEAT mode only.
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.
Cooling/heating capacity is reduced during lowest fan speed setting.| The lowest fan speed is to have a low noise operation, so cooling/ heating capacity may be reduced depending on the condition. Increase the fan speed to increase the capacity.
In COOL mode, when the room temperature reaches near the set temperature, the compressor stops, then the indoor unit fan speed reduced.| To prevent the room humidty rising. The indoor fan will resume running according to the set fan speed when room temperature increase.
Indoor fan stops occasionally during heating operation.| To avoid unintended cooling effect.
Indoor fan stops occasionally during automatic fan speed setting.| This is to help remove the surrounding odour.
Airflow continues even after operation has stopped.| To extract the remaining heat from the indoor unit (maximum 30 seconds).
During deice operation, flap is closed.| The AIR SWING is set to AUTO.
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.
• During heating operation, frost formed on the outdoor unit during deice cycle melts and is discharged as water or steam.

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.
Soft buzzing sound from indoor unit during nanoe™X operation.| It is normal when the nanoe™X generator is working. If you are concerned about the sound, cancel the nanoe™X operation.
Wireless LAN indicator is ON when the unit is OFF.|

• The unit’s wireless LAN connection with the router has been activated.

Operation in HEAT/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™X indicator at the indoor unit is not ON when nanoe™X is activated.| Use the remote control to retrieve the error code and consult an authorised dealer.

When…

• **The remote control is missing or a malfunction has occurred

**

1. Raise the front panel.
2. Press AUTO OFF/ON once to use in AUTO mode.
3. Press AUTO OFF/ON hold for 5 seconds until you hear 1 beep, then release to use in forced COOL mode. (This operation shall be performed by service personnel)
4. Press AUTO OFF/ON hold for 8 seconds until you hear 2 beep, then release to use in forced HEAT mode. (This operation shall be performed by service personnel)
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 COOL or HEAT 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:
    COOL: ≥ 8 °C / 14.4 °F HEAT: ≥ 14 °C / 25.2 °F

• The units will be not used for an extended period

  • Activate HEAT 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

How to retrieve error codes

If the unit stops and the TIMER indicator blinks, use the remote control to retrieve the error code.

1. Press for 5 seconds
2. Press for 5 seconds to quit checking
3. Press until you hear beep sound, then write down the error code
4. Turn the unit off and inform the error code to an authorised dealer

For certain errors, you may restart the unit for limited operation if there are 4 beeps when operation starts.
