5. Maintenance of Your Projector
Please request your dealer to perform cleaning of the projector inside.
5.1.
Cleaning the Cabinet
Before carrying out maintenance of your projector, be sure to always check that the projector is turned off and the power plug is unplugged
from the electrical outlet.
• Wipe with a dry, soft cloth without nap.
When the cabinet is excessively dirty, wipe with cloth well wrung after being dampened with a neutral detergent diluted with water and then
finish up with a dry cloth.
When you use a chemical dust cloth, follow the instructions in the manual attached to it.
• Do not use a solvent, such as thinner or benzene. The coating may deteriorate or peel off.
• When removing dust on the ventilation opening, suck it off using an adapter with a brush on a vacuum cleaner. Never allow the cleaner
without an adapter to come into direct contact or use a nozzles adapter in cleaning.
• Clean the ventilation opening at regular intervals. Dust, if allowed to accumulate there, may cause heating inside, which leads to
functional trouble. The interval, which can vary with the location of your projector, is about 100 hours.
• Do not damage the cabinet by scratching it or allowing hard objects to hit it. This can scratch the projector.
• Consult your dealer/distributor about cleaning the inside of the projector.
Do not allow insecticide or other volatile liquid to splash on the cabinet, lens or screen. Also, do not allow any rubber or plastic object to
remain in contact with the cabinet for a long time. The coating may deteriorate or peel off.
5.2.
Cleaning the Lens
Clean the lens the same way as with camera lens (using a commercially available camera blower or cleaning paper for glasses). Take
care not to damage the lens when cleaning.
5.3.
Cleaning and Replacing the Air Filters
Air filters are attached over the air inlet of the projector to prevent dust. The air filters should be cleaned periodically in order to maintain
projector performance. The air filters should also be replaced with new filters after roughly 10,000 hours.
•
You can view the usage time of the air filters in “Information” - “Usage” in the adjustment menus (See page 46).
•
When ordering replacement air filters, specify the part number (NP-11AF01).
•
When replacing air filters, replace the air filter in the front panel of the projector (1 piece) and the air filters in the rear panel (2 pieces) at the
same time. If you do not replace the air filters at the same time, the usage time cannot be calculated correctly.
When replacing air filters, turn off the projector and unplug the power cable.
Dust in air filters will hinder ventilation of the projector, lead to a rise of the internal temperature and can cause a fire or
malfunction.
Before replacing the filters, turn off the projector, disconnect the power cable and then allow the cabinet to cool. Failure
to do so can result in electric shock or burn injuries.
