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

• See below.

  Cleaning the Air Filters

  You need to clean the projector's air filters in the following situations:
  • The filter or vents get dusty.
  • You see a message telling you to clean it.
  • The projector's Filter light flashes orange.

  Note: The projector has one air filter on the front and two on the sides. The illustrations here show cleaning the air filter on the front, but the steps are the same to clean the filters on the side.
  

  1. Turn off the projector, wait for the projector to beep, and unplug the power cord.
  2. Loosen the screw 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 air filter 4 to 5 times to shake off any excess dust.
     
     

     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 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 and push gently until it clicks into place.
     
  8. Close the air filter cover.
     
  9. Tighten the screw to secure the air filter cover.
     
  10. Repeat these steps to clean the other air filters.

      Note: The air filter cover on the side of the projector is attached to a cord to prevent it from falling.
