13. Preventative maintenance actions
13.1 1 month maintenance actions
MAINTENANCE TYPE A (perform every month)
The 1 month maintenance actions, listed below, may be performed by a trained projectionist who is familiar
with potential hazards associated with the product.
No. Maintenance action Remarks
1 Check both dust fi lters of the projector for dust and grease .
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.
• If the fi lters are contaminated with dust than cleaning the fi lters with a
vacuum cleaner should be suf fi cient.
• In case the fi lters feel greasy than the fi lters must be washed .
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.
Replace damaged fi lters immediately.
See procedures "Check the large dust
fi lter", page 106, and "Check the small
dust fi lter", page 108.
2 Check the surface of the lens output side for dust. (it is not needed to remove
the lens from the projector). Only clean if necessary. Clean the lens output side in case dust
is clearly visible upon the surface.
Note: if the lens was removed from
the projector, a manual “Lens Home
& Return” action must be executed
to calibrate the position of the lens in
relation to the Lens Holder. This way
the references of the existing ’lens
fi les’
remain valid. See user guide of the
Communicator software.
3 Check the porthole (both sides) for dust. Clean the porthole in case dust is clearly
visible upon the surface. Use an optical
cloth.
