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.
