About this chapter
This chapter describes how to remove the dust filters
The air filters should be cleaned monthly under normal environment conditions. Equipment in very
dusty or otherwise contaminated areas may require more frequent maintenance.
If the air filters are not regularly cleaned, the air flow inside the projector could be disrupted and
cause overheating. Overheating may lead to the projector shutting down during operation.
