Air filters help prevent dust from accumulating on the optical elements inside the projector. To whatever extent the air filters
become clogged with dust particles, the cooling fans’ effectiveness is reduced, which may result in an internal heat build-up
and adversely affect the life of the projector. Therefore, for appropriate care and use of the projector, regular cleaning of the
air filters is necessary.
How often the air filters should be cleaned really depends upon the environment in which the projector is being operated. As
a rough guide, under a normally clean operating environment, the air filters should be cleaned approximately every 200
hours of use. However, if the projector is being operated in a somewhat dusty or smoky environment, the air filters should be
cleaned more often; for consistently good projector operation and performance, timely cleaning of the air filters is a very
important factor. When appropriate, clean the air filters following the steps below.
NOTE: If the dust cannot be removed by
cleaning, it is probably time to replace
the air filters with new ones. Please
consult your dealer.
