CONTENTSAir filter cleaning
CAUTION
If you use the projector mounted on the ceiling,
ask the dealer to carry out the maintenance
such as cleaning.
The filter inside the air filter cover is the part
to shut out dusts or dregs.
Do not use the projector with the filter taken
off.
We recommend you clean the air filter
frequently. (The cleaning period is once per
50 hours approximately).2 1
Unplug the power cord.
Take off the front cover.
Slide the front cover rightward side for
about 3 mm, then the front cover can be
taken off toward you.
Detach the air filter.
Take off the filter frame by pulling the
middle part of it toward you, then detach
the air filter.
Clean the air filter.
Use a vacuum cleaner to carefully remove any dust and dirt from the front
cover, air filter and filter frame.
Be careful that the air filter is not sucked into the vacuum cleaner.

Notes
•When the air filter is dusty, the ventilation is
impaired. This causes the temperature inside the
projector to rise, and may damage the unit.
•Attach the air filter and the filter frame firmly after
the cleaning. If it is not set correctly, the dusts will
enter and they will be projected and overlapped on
the picture.
•If you wash the air filter with water, be sure to let it
dry fully before reinstalling it.  Using it damp will
result in malfunction.
•If the air filter is damaged, contact your store of
purchase and replace it with a new one.  Using a
damaged air filter will cause dust or dirt to get
inside the projector and onto the images.

synthetic detergent and water, and finish with
a soft, dry cloth.
Replacing the intake, exhaust fans and air filter
To maintain the efficiency of the projector, replace the intake and exhaust
fans about every two to three years.

*”: TLP250/TLP251, “

data may be missing or their picture quality may be degraded.
• With analog RGB inputs, if the signal source’s dot clock frequency exceeds 165 MHz, some pixel signals cannot be sampled.
