Air Filter Cleaning Procedure
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.
2
Vacuum away the dust
Remove the air filter from the cover and use a
vacuum to suck away the dust from the outside
surface of the air filter.
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.
• Be careful not to forget to install the air filter. Leaving the projector without a filter installed will allow dust
to enter the inside of the projector and the image quality may worsen.
• When the air filter is damaged, be sure to replace it with a new air filter (available separately as the
MPAF-C1). Use of the projector with a damaged filter will result in dust entering the inside of the
projector and this will cause the image quality to worsen.
CAUTION
NOTE: The lamp will not light unless the air fiter is installed.
