Possible faults and solutions:

Do not attempt to repair the unit yourself. Improper repair can cause electric shocks or fire. Disconnect the unit from the power supply before contacting your local Technical Service Centre. Carry out the following checks before contacting your Technical Service Centre:

Fault: The indoor unit does not receive the signal from remote control or the remote control does not seem to be working

Check:

  1. Is there noticeable interference (e.g. static electricity, stable voltage)?
  2. Is the remote control within the signal reception range? Are there any obstacles between the remote control and the receiver?
  3. Is the remote control pointed at the receiver?
  4. Is the remote control’s sensitivity low? Are icons blurred or missing?
  5. Do icons fail to appear on the display when you operate the remote control?
  6. Is there a fluorescent light in the room?

Solution:

  1. Pull out the plug. After about 3 minutes reinsert the plug and restart the unit.
  2. The maximum signal reception distance is 8 m. The remote control will not work beyond this distance. Remove the obstacles.
  3. Point the remote control at the receiver on the indoor unit.
  4. Check the batteries. If the batteries are very low, replace them.
  5. Check if the remote control is damaged. If it is, replace it.
  6. Position the remote control next to the indoor unit. Turn off the fluorescent light and try again.

Fault: No air comes out of the indoor unit

Check:

  1. Is the indoor unit’s air inlet or outlet blocked?
  2. In heat mode, has the indoor temperature reached the set temperature?
  3. Has heat mode only recently been selected?

Solution:

  1. Remove the obstruction.
  2. Once the set temperature has been reached, the indoor unit will stop blowing out air.
  3. To prevent blasts of cold air from being blown out, there will be a delay of several minutes before operation begins (this is normal).

Fault: The air conditioner is not working

Check:

  1. Is there a power cut?
  2. Has the plug come loose?
  3. Has the circuit breaker tripped or has the fuse blown?
  4. Is the wiring faulty?
  5. Was the unit restarted immediately after shutdown?
  6. Is the setting on the remote control correct?

Solution:




  1. Wait for the power to be restored.
  2. Reinsert the plug
  3. Have the circuit breaker or fuse replaced by a qualified technician.
  4. Have it replaced by a qualified technician.
  5. Wait 3 minutes and then restart the unit.
