Cleaning the Air Filter
The air filter is an important part that prevents the intrusion of dust onto the optical parts and other parts inside the projector. When the air filter becomes blocked, the internal temperature will rise and the rotation of the fan will also increase leading to a reduction of the service life or causing breakdown. In view of this, the air filter should be cleaned regularly (about once a month, when the projector is used 4 hours per day).
Note that the air filter should be replaced with a new one when it becomes difficult to clean out the dust.
Air Filter Cleaning Procedure
1 Remove the air filter cover
Press the 2 tabs of the air filter cover downward while swinging the cover outward to remove the air filter cover.
2 Vacuum away the dust
Please vacuum away the dust from the outside (protruding side) of the air filter as illustrated in the diagram.
3 Install
Installation is performed by following the steps for removal in reverse order. Press in the air filter cover until a click sound is heard.
| Air filter care and precautions | |
| • Do not wash with water nor with hot water. Doing so will cause blockage. | |
| • Do not wipe with a cloth or damp rag. Doing so will cause blockage. | |
CAUTION | • Always vacuum from the outside of the air filter. If you vacuum from the inside of the air filter, this will | |
reduce the effectiveness of the air filter. | ||

•Do not forget to install the air filter. If the projector is left without the air filter installed, dust may enter the projector and cause dirty projected images.
•When the air filter becomes damaged, be sure to replace it with a new one (sold separately). If the projector is used with the air filter damaged, dust may enter the projector and cause dirty projected images.
NOTE: The lamp will not light unless the air fiter cover is installed.
