About this chapter
This chapter describes in chronological order the overall cleaning process of the projector. Starting with the
light source, following the light path up to the porthole of the installation booth. Furthermore, the airflow
channels and compartments (non optical parts) are also taken into account. Extra attention is paid to critical
and/or fragile components which need special treatment.
To access the components for cleaning, several parts of the projector have to be disassembled. For detailed
disassembly and assembly instructions this chapter refers where relevant to other chapters in this service
manual.
Purpose of projector cleaning
Projectors are not used in 100% ideal circumstances and due to that they might get contaminated by particles
in the environment air. Due to this contamination the light output can be reduced or overheating may occur
which may also lead to a projector shutdown during operation.
To keep the projector in a good shape, it is advised to clean the projector as suggested in the preventative
maintenance section. Dust filter cleaning, cover cleaning and projection lens cleaning can be done by the
operator of the projector. The inside cleaning of the light path must be done by a trained and certified
service engineer.
