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.

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.
