Cleaning the Air Filter

When “Please clean the filter. Have you finished? Yes V No v” appears on the screen, you should clean the air filter.

The air filter should be cleaned every 1250 hours. This value varies depending on the environment or how the projector is used. 1250 hours are approximate.

1Turn the power off and unplug the power cord.

2Place a protective sheet (cloth) beneath the projector and turn the projector over.

3Remove the filter holder.

When the air filter cover (supplied) has been attached because the projector is installed on the ceiling, remove this air filter cover before removing the filter holder.

For detailed information on the air filter cover, see “To attach the supplied air filter cover for ceiling installation” (1 page 76).

4 Remove dust with a vacuum cleaner.

Note

Be careful that the filter does not get caught in the vacuum cleaner.
