Cleaning And Replacing The Air Filter - Hitachi CP-A300N User Manual

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.
Type number : UX37191 (Filter set)
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.
1.
Turn the projector off, and unplug the power cord.
Allow the projector to sufficiently cool down.
2.
Use a vacuum cleaner on and around the filter cover.
3.
Slide the filter unit upward to take it off from the
projector.
4.
Use a vacuum cleaner for the filter vent of the
projector.
5.
Take the fine meshed filter out while holding the
filter cover. It is recommended to leave the coarse
meshed filter in the filter cover as it is.
6.
Use a vacuum cleaner on both sides of the fine
meshed filter while holding it so it will not be sucked
in. Use a vacuum cleaner for the inside of the filter
cover to clean up the coarse meshed filter. If the
filters are damaged or heavily soiled, replace them
with new ones.
7.
Put the fine meshed filter on the coarse meshed one,
turning its stitched side up.
