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.
