Filter-Cleaning Procedures

This bulletin was created to inform users about the filter-cleaning procedures necessary for

maintaining proper airflow and reducing the potential for overheating.

Reason:

The PowerLite 8300 and 9300 series projectors have five (5) filters that must be cleaned on a regular

basis. Cleaning the filters is critical to maintaining proper airflow inside the projector and reducing

possible overheating issues. Incomplete or infrequent filter-cleaning maintenance can cause one or

more filters to accumulate excessive dust over time. This can inhibit proper airflow so that the

projector begins to overheat during operation and eventually shut down. The next section provides

information on the location of the filters on the projector, cleaning instructions and recommended

maintenance schedules.

Action:

The following filters should be cleaned after every 100 hours of use. For dusty environments, filter

cleaning should be performed more frequently.

1) Wire mesh filter (inside lamp housing shutter):

Hold shutter open and use a computer vacuum to remove dust.
