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. It is recommended that you clean these parts at least once every three months, or 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. Carefully turn the projector upside down.
  3. Gently remove the dust using a small vacuum designed for computers or a very soft brush (such as a paintbrush).
     
     
  4. Carefully turn the projector over and place it as shown.
     
     
  5. Remove the front cover.
     
     
  6. Slide the air filter cover latch and pull out the air filter cover.
     
     
  7. Pull the air filter out of the projector.
     
     
  8. Vacuum the front of the air filter (the side with the tabs) to remove any remaining dust.
     
     

     Caution:
     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.

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

  9. Place the air filter back in the projector with the four tabs facing down as shown.
     
     

     Caution:
     Do not try to force the air filter cover closed if the tabs of the air filter are facing up. You could damage the projector.

  10. Insert the air filter cover and then push it up until it clicks into place.
  11. Replace the front cover.
