Maintaining and Transporting the Projector 71
Cleaning and Replacing the Air Filter
Clean the air filter and air intake and exhaust vents on the bottom and
rear of the projector after every 100 hours of use. If they are not
cleaned periodically, they can become clogged with dust, preventing
proper ventilation. This can cause overheating and damage the
projector. When the filter and vents are clogged, the projector displays
the message
The projector is overheated .
To clean the air filter and air vents, follow these steps:
1. Press the P Power button twice to turn off the projector. When
you hear the projector beep twice, unplug the power cord.
2. Clean the air vent on the back of the projector.
3. Carefully turn the projector upside-down and clean the filter and
air intake vents on the base of the projector.
To clean the filter and air vents, Epson recommends using a small
vacuum cleaner designed for computers and other office
equipment. If you don’t have one, gently clean them using a very
soft brush (such as an artist’s brush).
If the dirt is difficult to remove or if the filter is torn or bent,
replace it. Contact your dealer or call Epson at (800) 873-7766 to
obtain a new one. The air filter set (part number V13H134A06)
contains two filters. In Canada, please call (800) 463-7766 to
locate a dealer.
note
You may also need to clean
the vents and filter if the
Temp light on top of the
projector is red or flashing
orange. See page 80 for
