5. Maintenance of Your Projector
5-3-2. Warnings About Replacing the Air Filter
Air filters are attached over the air inlet of the projector to prevent dust. Replace air filters periodically to maintain the projector’s
performance.
WARNING:
• 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.
CAUTION
Before replacing the filters, turn off the projector, disconnected the power cable and then allow the cabinet to cool. Failure
to do so can result in electric shock or burn injuries.
• Please purchase the replacement air filter at your dealer/distributor. Specify the NP-9AF01 (optional) when you order.
• A replacement lamp and air filter kit is also provided. Specify NP-9LP01 as the model number for the replacement lamp and
filter kit when ordering.
• Always replace both of the air filters at the same time. If you do not replace both of the air filters, the air filter usage time will
not be calculated correctly.
