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.
  1. Turn off the projector and unplug the power cord.
  2. For the Home Cinema 2200, 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. For the Home Cinema 2250, remove the air filter cover.
     
     
  4. Remove the air filter.
     
     
  5. Tap each side of the air filter 4 to 5 times to shake off any excess dust. Do this outside the room or away from the projector.
     
     
  6. Vacuum the front of the air filter (the side with the tabs) to remove any remaining dust.
     
     
  7. Insert the cleaned air filter back into the projector.
     
     
  8. Replace the air filter cover.
     
  9. If dust is difficult to remove or the air filter is damaged, replace the air filter.
