14. Preventative maintenance actions
14.1 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 then cleaning the fi lters with a
vacuum cleaner should be suf fi cient.
• If the fi lters feel greasy then 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 reason, it is 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 "Vacuum cleaning of
the dust
fi lters", page 113, and "Washing
and drying the dust fi lters", page 114.
To speed up drying, allow the fi lter(s)
to dry at 50°C max in a well ventilated
room.
2 Check the surface of the lens output side for dust (it is not necessary to remove
the lens from the projector to do this). Clean only if necessary. Clean the equipment if dust is clearly
visible upon the surface of the lens
output side.
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 if dust is clearly
visible upon the surface. Use a clean
dry micro-
fi ber cloth suitable for cleaning
optics.
