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. Clean them more often if you use the projector in an environment that is dustier than expected.

  Caution:
  Do not use water or any detergent to clean the air filter. Do not use canned air, or the gases may leave a flammable residue.

  1. Turn off the projector and unplug the power cord.
  2. Loosen the screws securing the air filter cover.
     
     
  3. Open the air filter cover.
     
     
  4. Pull the air filter out of the projector.
     
     
  5. Tap each side of the filter 4 to 5 times to shake off any excess dust. Do this outside the room or away from the projector.

     Caution:
     Do not use excessive force when tapping the air filter, or it may crack and become unusable. Do not rinse the air filter in water, or use any detergent or solvent to clean it. 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.

  6. Vacuum the front of the air filter (the side with the tabs) to remove any remaining dust.
     
     

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

  7. Place the air filter back in the projector as shown.
     
     
  8. Close the air filter cover and tighten the screws.
