Cleaning and replacing the air fi lter
The air fi lter unit of this projector consists of a fi lter cover, two kinds of fi lters, and
a fi lter frame. The new double large fi lters system is expected to function longer.
However, please check and clean it periodically to keep ventilation needed for
normal operation of the projector.
When the indicators or a message prompts you to clean the air fi lter, comply with
it as soon as possible. Replace the fi lters when they are damaged or too soiled.
To prepare new fi lters, make contact with your dealer and tell the following type
number.
Type number : UX37191 (Filter set)
When you replace the lamp, please replace the air fi lter. An air fi lter of specifi ed
type will come together with a replacement lamp for this projector.

Turn the projector off, and unplug the power cord.
Allow the projector to suffi ciently cool down.
2.
Use a vacuum cleaner on and around the fi lter cover.
3.
Slide the fi lter unit upward to take it off from the
projector.
4.
Use a vacuum cleaner for the fi lter vent of the
projector.
5.
Take the fi ne meshed fi lter out while holding the
fi lter cover. It is recommended to leave the coarse
meshed fi lter in the fi lter cover as it is.

Use a vacuum cleaner on both sides of the fi ne
meshed fi lter while holding it so it will not be sucked
in. Use a vacuum cleaner for the inside of the fi lter
cover to clean up the coarse meshed fi lter. If the
fi lters are damaged or heavily soiled, replace them
with new ones.

Put the fi ne meshed fi lter on the coarse meshed one,
turning its plastic band side up.
