• If you do not know the dust concentration in the area of installation, it is recommended that you
replace the filter before summer begins every year.
• Especially in a location exposed to a lot of dust, the filter must be replaced at least every 6
months. A partially dark screen is likely a result of the filter being used longer than the rec-
ommended replacement cycle. Replace the filter immediately.
•
In Europe and the United States, the yearly mean dust concentration is less than 30
and
the recommended replacement cycle is about 21 months. In Korea, the yearly mean dust con-
centration is less than 60 and the recommended replacement cycle is about 11 months.
The dust concentration and recommended replacement cycle may vary according to the location
of installation.
