5.5 Air Filters
5.5.1 Light Engine Air Filter
NOTICE:
DO NOT try to clean and reuse old filters. The air filters used in this product cannot be cleaned
thoroughly enough for reuse. Reusing filters can lead to the contamination of optical components.
(Estimated Replacement Time: 4 minutes)
The main air filter of the projector is located on the
operator’s side of the projector near the front. It is
responsible for cleaning the intake air into the light
engine compartment. It is strongly recommended this
filter be replaced whenever a lamp is replaced or sooner
in dusty and/or dirty environments. No tools required.
1. Push down on the two snap tabs at the top of the
cover (See Figure 5-8 ).
2. Lift the cover up enough for the bottom tabs to clear
the frame and remove.
3. Slide the air filter out from behind the air filter
cover and discard ( Figure 5-11 ).
4. When replacing, insert a new air filter with the
airflow indicator pointing into the projector. This
will ensure contaminants are not forced into the
projector.
