OPTIONAL PARTS

2-1. AIR CLEANING FILTER
Every 3 months:

  • Remove dirt by a vacuum cleaner.
    When dirt cannot be removed by vacuum cleaning:

  • Soak the filter and its frame in lukewarm water before rinsing it.

  • After washing, dry it well in shade.

Every year:

  • Replace it with a new air cleaning filter for best performance.
    NOTE 1: Clean the filters regularly for best performance and to reduce power consumption.
    NOTE 2: Dirty filters cause condensation in the air conditioner which will contribute to the growth of fungi such as mold. It is therefore recommended to clean air filters every 2 weeks.
