How to check the small dust filter?
1. Loosen the captive screw (reference 1 image 14-3) of the small dust filter assembly using a 7mm flat screwdriver.
2. Remove the dust filter assembly from the projector by pivoting the assembly away from the projector as illustrated. Note that the
other side of the assembly contains a mounting lip (reference 2 image 14-3) which is engaged in the projector chassis.

3. Detach the dust filter from the cover plate. Do this by pushing the two latches (reference 3 image 14-4) of the dust filter inwards.
4. Check the "air in" side of the dust filter for dust and/or grease.
In case the filter is contaminated with grease wash and dry the dust filter. See cleaning procedure "Washing and drying the dust
filters", page 111.
In case the filter contains dust but doesn't feel greasy then vacuum clean the dust filter. See procedure "Vacuum cleaning of the
dust filters", page 110.
Note: Grease on the filter can build up after several months in an environment contaminated with greasy air. Note that areas
where popcorn is consumed are subject for greasy air.
Tip: Take into account that the time needed to dry the dust filters may be 24 hours or more. For that, it's recommended to
have a second set of dust filters which can be used while cleaning the first set.
5. Attach a clean dust filter to the cover plate. Ensure that both latches (reference 4 image 14-4) of the dust filter are engaged.
Caution: UNDER NO CIRCUMSTANCES SHOULD WET FILTERS BE INSTALLED BACK INTO THE PROJECTOR. THIS
CAN HAVE SERIOUS SAFETY CONSEQUENCES AS WELL AS JEOPARDIZE THE INTERNAL OPTICS OF THE
SYSTEM.
