Air Filter Cleaning Procedure
Cleaning the Air Filter
The air lter is an important part that prevents the intrusion of dust onto the optical parts and other parts inside
the projector. When the air lter 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 lter should be
cleaned regularly (about once a month, when the projector is used 4 hours per day).
Note that the air lter should be replaced with a new one when it becomes difcult to clean out the dust.

Air lter 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.
• Be careful not to forget to install the air lter. Leaving the projector without a lter installed will allow
dust to enter the inside of the projector and the image quality may worsen.
• When the air lter is damaged, be sure to replace it with a new air lter. Use of the projector with
a damaged lter will result in dust entering the inside of the projector and this will cause the image
quality to worsen.
