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 : UX36761 (Filter set)

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.
