■ Cleaning the Air Filter
The air filter is an important part as it keeps the optical components inside your projector
free from dirt and dust. A clogged air filter can cause the temperature to rise inside your
projector and the fan speed to increase. This, in turn, may reduce lamp life or cause the
projector to malfunction. The air filter should be cleaned regularly (about once a month if
the projector is used four hours a day).
Replace with a new air filter if it is difficult to remove dust and dirt from the air filter.
Procedure
1 Remove the air filter.
Pull the air filter in the direction of the arrow while
pressing in the indent to remove.
2 Vacuum the sponge to take off dust.
Vacuum the outside surface of the sponge as shown in
the illustration.
3 Mount the air filter.
Follow step 1 in reverse order.
CAUTION
Caring for the Air Filter and Cautions
• Do not wash the air filter with water or other liquids. This may cause the filter to clog.
• Do not wipe the air filter with a cloth or a wet rag as this, too, may cause the filter to clog.
• 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 with a new one. 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 filter is mounted.
