Warranty Information

No warranty information is available in the provided document sections.

  • Fast Cooling: Provides the strongest cool air.
  • Wind-Free Cooling: Delivers a mild breeze through fine holes, not directly from blades.
  • Motion Detection: Detects people and adjusts airflow; enters energy-saving mode if no motion is detected.
  • Eco Mode (Single User): Minimizes energy consumption by adjusting compressor capacity.
  • Easy Filter: Filter can be easily removed and cleaned without removing the grille.
  • Good'sleep Function: Adjusts temperature, fan speed, and airflow for better sleep.
  • Smart Install: Performs a trial operation to check installation accuracy.
  • Easy Installation: Simplified wall mounting and pipe/wire connection.
