How to check the large dust fi lter?
1. Loosen the two captive screws (reference 1 image 15-1) of the large dust fi lter assembly using a 7mm fl at screwdriver.

3. Detach the dust fi lter from the cover plate. Do this by pushing the two latches (reference 3 image 15-2) of the dust fi lter inwards.
4. Check the “air in” side of the dust fi lter for dust and/or grease .
In case the fi lter is contaminated with grease wash and dry the dust fi lter. See cleaning procedure "Washing and drying the dust
fi lters", page 135.
In case the fi lter contains dust but doesn’t feel greasy then vacuum clean the dust fi lter. See procedure "Vacuum cleaning of the
dust fi lters", page 134.
Note: Grease on the fi lter can build up after several months in an environment contaminated with greasy air. Note that areas
where popcorn is consumed are subject to greasy air.
Tip: Take into account that the time needed to dry the dust fi lters may be 24 hours or more. For that, it’s recommended to
have a second set of dust fi lters which can be used while cleaning the fi rst set.
5. Attach a clean dust fi lter to the cover plate. Ensure that both latches and both mounting lips (reference 4 image 15-2) of the dust
fi lter 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.
