Air filter cleaning
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.)
Lens and main unit cleaning
s Lens cleaning
� Clean the lens with a commercially available blower and/or lens cleaner. � The lens is easily scratched, so do not rub it with hard objects, or strike it.
CAUTION
� Request cleaning and maintenance of a ceiling-mounted unit from your projector dealership.
s Main unit cleaning
� Clean the main unit after unplugging the power cord. � Wipe dirt off the main unit gently with a soft cloth. � If the soiling is severe, dip the cloth in a neutral detergent diluted in water, wring well, and gently wipe off the dirt, then finish up by wiping with a dry cloth.
1 Unplug power cord. 2 Remove the air filter.
Pull out the air filter by taking the catch shown in the figure.
q Replacing air intake and exhaust fans, and air filter
To maintain the performance, it is recommended that these should be replaced about every 2 to 3 years. Consult with your dealer for details.
3 Clean the filter.
Carefully remove the dust and dirt from the air filter with a vacuum cleaner or the like.
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.
4 Replace the air filter.
CAUTION
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 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.
1 Unplug power cord. 2 Wait until lamp is sufficiently cooled.
Wait for at least 1 hour.

Maintenance
� Request cleaning and maintenance of a ceiling-mounted unit from your projector dealership. � When replacing, always use lamp �TLPLV1� (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.
