Stop the unit and switch off the breaker first. The manual explains removing, washing and drying the filters and warns not to clean inside parts yourself.

From the manufacturer's documentation (English source wording, with page)

  1. Before cleaning, be sure to stop the operation, turn the breaker off or pull out the supply cord[1]
  2. Do not use gasoline, benzene, thinner, polishing powder or liquid insecticide; do not use water or air of 40°C or higher[2]
  3. As an end user, you may never clean inside parts of the unit by yourself; this work must be performed by a qualified service person[3]
  4. Do not touch the heat exchanger fins. These fins are sharp and could result in cutting injuries[4]
  5. Operating the unit with dirty filters: cannot deodorise the air, cannot clean the air, poor heating/cooling, causes odour[5]
  6. 7.5: Hold the front panel by the panel tabs on both sides and open it[6]
  7. 7.6: Push the tab at the centre of each air filter, then pull it down; pull out the air filters[7]
  8. Wash the air filters with water or clean them with a vacuum cleaner[8]
  9. Soak in lukewarm water for about 10 to 15 minutes; install all filters back in their original positions[9]
  10. If the dust does not come off easily, wash them with a neutral detergent diluted in lukewarm water. Dry the air filters in the shade[10]
  11. It is recommended to clean the air filters every 2 weeks[11]
  12. 7.7: Gently press the front panel at both sides and at the center until it clicks[12]
  13. Before a long idle period: operate the unit in fan only mode for several hours to dry the inside; after operation stops, turn the breaker off; clean the air filters; remove the batteries from the remote control[13]

⚠ Work on refrigerant circuits, mains electricity and PV DC wiring is for qualified technicians only.
