Cleaning and replacing the air filter
The air lter unit of this projector consists of a lter cover, two kinds of lters, and
a lter frame. The new double large 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 lter, comply with
it as soon as possible. Replace the lters when they are damaged or too soiled.
To prepare new 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 lter. An air lter of specied
type will come together with a replacement lamp for this projector.
1.
Turn the projector off, and unplug the power cord.
Allow the projector to sufciently cool down.
2.
Use a vacuum cleaner on and around the lter cover.
3. Slide the lter unit upward to take it off from the
projector.
4.
Use a vacuum cleaner for the lter vent of the
projector.
5.
Take the ne meshed lter out while holding the
lter cover. It is recommended to leave the coarse
meshed lter in the lter cover as it is.
6.
Use a vacuum cleaner on both sides of the ne
meshed lter while holding it so it will not be sucked
in. Use a vacuum cleaner for the inside of the lter
cover to clean up the coarse meshed lter. If the
lters are damaged or heavily soiled, replace them
with new ones.
7.
Put the ne meshed lter on the coarse meshed one,
turning its stitched side up.
8.
Put the lter unit back into the projector.
