Air Filter; Cleaning The Projection Lens - Sanyo PLC-SW30 Owner's Manual

Air Filter

Removable air filters prevent dust from accumulating on the surface of optical elements inside the projector. Should air
filters become clogged with dust particles, it will reduce the cooling fans' effectiveness and may result in internal heat build
up and adversely affect the life of the projector. Clean air filters following the steps below:
1 Turn off the projector, and disconnect AC power cord from the
AC outlet.
2 Turn the projector upside down and remove air filters by pulling
the latches upward.
3 Clean the air filters with a brush or wash out dust and particles.
4 Replace each air filter properly. Make sure that the air filters are
fully inserted.
CAUTION
Do not operate the projector with the air filters removed.
Dust may accumulate on optical elements inside the
projector degrading picture quality.
Do not put small parts into Air Intake Vents. It may result in
malfunction of the projector.
RECOMMENDATION
We recommend avoiding dusty/smoky environments when
operating a projector. Usage in these environments may cause
poor image quality.
When using under dusty or smoky conditions, dust may accumulate
on or optical elements inside the projector. This condition may
degrade the quality of a projected image.
When the above symptoms are noticed, contact your authorized
dealer or service station for proper cleaning.
