PARTICLE SENSOR CLEANING (CLEAN EVERY 2 MONTHS)
If there are dust or foreign objects in the particle sensor, the dust density may be detected as high, so clean it periodically to remove the dust. If not cleaned periodically, the particle sensor performance will be degraded. The cleaning cycle may differ depending on the environment.
Clean more often in very dusty environments. Do not let dust drop into the air vent hole when you clean it.
- Use a vacuum cleaner or a soft brush to clean the dust outlet and dust inlet. Use the lowest power of the vacuum cleaner to clean.
- Clean the dust outlet and dust inlet with a wet cotton swab, then wipe them off with a dry cotton swab to remove moisture from them.
