Possible cause and solution:

  1. Power failure/disconnected/loose connections; check the power supply and ensure the unit is properly connected.
  2. Timer-on function is activated; cancel it.
  3. Damaged indoor/outdoor unit fan motor; call the after sales support line to arrange a service.

  6. Voltage is higher or lower than the required range; call for service.
  7. Electronic control board is damaged; call for service.

Problem: Remote control is unresponsive

Possible cause and solution:

  1. Remote control is too far away; move closer to the indoor unit
  2. Remote control batteries are flat; replace.
  3. Path to the signal receiver is blocked; remove obstructions

Problem: Cooling (Heating) efficiency is not good

Possible cause and solution:

  1. Unsuitable temperature setting — adjust fan speed.
  2. Blocked air intakes/ outlets — clear obstructions.
  3. Dirty air filter — clean the filter.
  4. Fan speed is set to LOW — increase.
  5. Other sources of heat in the room — check

Problem: Indoor unit does not work straight after restarting it

Possible cause and solution: This is not a fault. Once the air conditioner is stopped, you will have to wait for approximately 3 minutes before the unit can be restarted

Problem: Strange odour coming from the outlet

Possible cause and solution:

  1. Odour in the room (from building material, furniture or smoke) is recirculated
  2. Dirty air filter — clean the filter

Problem: Noise like running water when cooling

Possible cause and solution: Refrigerant is flowing inside the unit — no cause for concern

Problem: Mist is emitted when cooling

Possible cause and solution: Cold air used for rapid cooling of the air in the room may resemble fog — no cause for concern

Problem: Mist is emitted when heating

Possible cause and solution: Moisture from the defrosting process generates mist — no cause for concern.

Problem: Low noise is emitted during operation.

Possible cause and solution:

  1. A low hissing sound is caused by the refrigerant flowing.
  2. A low squeak sound is caused by the plastic parts expanding and contracting due to temperature fluctuations.

Problems with Wi-Fi connectivity

Problem: App does not show the air conditioner.

Possible cause and solution:

  1. Check and ensure you have Wi-Fi enabled on your smartphone.
  2. Check and ensure your smartphone and the air conditioner are connected to the same wireless router.
