Replacing the Air Filter

The air filter is intended to prevent dust and other airborne particles from entering the chassis and adversely affecting its components. To maintain proper operation of the device, you must periodically replace the air filter. The frequency of replacing the air filter depends on the cleanness at the installation site. In installation rooms with extra-building openings (exposed to dust and/or air particles), you may need to replace the air filter once every 3 months. In cleaner rooms (e.g., no extra-building openings), you may need to replace the air filter once every 6 months. In air-purified (conditioned) rooms, air filter replacement can be done annually. It's the user's responsibility to determine the cleanness level and the air filter replacement frequency.
