If the air ﬁlter becomes clogged by dust or the like, internal temperatures rise and

could cause a ﬁre, a burn and/or malfunction to the projector. When the indicators

or a message prompts you to clean the air filter, clean the air filter as soon as

possible.

Please check and clean the air filter periodically, even if there is no message.

Please replace the air ﬁlter when it is damaged or too soiled. Preparation of a new

air ﬁlter is recommended.

To prepare a new air ﬁlter

, contact your dealer and tell the air ﬁlter type number.

Type number = 78-8118-9641-0

And also when you replace the lamp, please replace the air ﬁlter. An air ﬁlter of

speciﬁed type will come together with a replacement lamp for this projector.

Turn the projector off, and unplug the

power cord. Allow the lamp to cool for at

least 45 minutes.

When the projector is suspended from

the ceiling, apply the vacuum cleaner to

and around the ﬁlter cover ﬁrst, to prevent

penetration of dust or the like.

While supporting the projector with one

hand, use your other hand to pull the ﬁlter

cover forward in the direction of the arrow.

Remove the air ﬁlter.

Maintenance
