Cleaning and replacing the air filter

The air filter unit of this projector consists of a filter cover, two kinds of filters, and
a filter frame. The new double large filters system is expected to function longer.
However, please check and clean it periodically to keep ventilation needed for
normal operation of the projector.
When the indicators or a message prompts you to clean the air filter, comply with
it as soon as possible. Replace the filters when they are damaged or too soiled.
To prepare new filters, make contact with your dealer and tell the following type
number.
