Maintenance

The air filter prevents dust and debris from getting inside the projector. Never run the

projector with the filter removed. It is recommended that the air filter is cleaned regularly.

(A recommended measure is about once for every 50 hours of use.)

CAUTION

• Request cleaning and maintenance of a ceiling-mounted unit from your projector

dealership.

Unplug power cord.

Remove the air filter cover.

Of the upper connection terminal cover is on, remove that

first.

Remove the air filter cover by pressing on the part in the

figure with your finger.

Remove the air filter.

Remove the air filter from the air filter cover. It can be

disassembled into the air filter cover, air filter, and filter

holder.

Clean the filter.

Carefully remove the dust and dirt from the air filter cover,

air filter, and filter holder with a vacuum cleaner or the like.

Be careful not to let the air filter be sucked into the

vacuum cleaner.

Assemble the air filter.

Insert the air filter into the air filter cover, and lock it in

place by putting the pegs of the filter holder through the

holes in the air filter cover.

Replace the air filter cover.

Notes

• Allowing dirt and dust to build up on the air filter will worsen the air circulation inside the

projector, causing the internal temperature to rise, causing the projector to stop working

or malfunction.

• Insert the air filter cover all the way in. Leaving gaps will allow dust and dirt to get inside

the projector.

• If you wash the air filer with water, make sure to dry it completely before replacing it.

• If the air filter is torn, consult with your dealer about replacing it with a new one.

Continuing to use a ripped filter will allow dust and dirt to get inside the projector.
