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.

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.

Lamp replacement
A lamp is consumable supplies. If used for extended periods, images will appear dark, and
the lamp could burn out. This is characteristic of a lamp, and is not malfunction. (The
lifetime of the lamp depends on conditions of use.) If this happens, replace it with a new
one.
CAUTION
• Request cleaning and maintenance of a ceiling-mounted unit from your projector
dealership.
• When replacing, always use lamp “TLPLW1” (sold separately).
• If you have been using the projector, the lamp will be very hot, and may cause burn
injuries.
Wait for the lamp to cool (for longer than 1 hour) before replacing it.
• If the lamp should break, please handle with care to avoid injury due to broken pieces
and contact your dealer for repair service.
