When and how should I clean or replace the air filter?

• See below.

  Cleaning the Air Filter and Vents

  Clean the projector's air filter or vents if they get dusty, or if you see a message telling you to clean them.

  Note: It is recommended that you clean these parts over a 20000-hour period. Clean them more often than this if you use the projector in a environment that is dustier than expected.

  1. Turn off the projector and unplug the power cord.
  2. Gently remove the dust using a small vacuum designed for computers or a very soft brush (such as a paintbrush).
     
     

     Note: You can remove the air filter so you can clean both sides of it. Do not rinse the air filter in water or use any detergent or solvent to clean it.

     Caution:
     Do not use canned air. The gases may leave a flammable residue or push dust and debris into the projector's optics or other sensitive areas.

  3. If dust is difficult to remove or the air filter is damaged, replace the air filter.

  Replacing the Air Filter

  You need to replace the air filter in the following situations:
  • After cleaning the air filter, you see a message telling you to clean or replace it
  • The air filter is torn or damaged

  You can replace the air filter while the projector is mounted to the ceiling or placed on a table.

  1. Turn off the projector and unplug the power cord.
  2. Open the air filter cover.
     
     
  3. Pull the air filter out of the projector.
     
     

     Note: Air filters contain polypropylene. Dispose of used air filters according to local regulations.

  4. Place the new air filter in the projector as shown.
     
     
  5. Close the air filter cover.
