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. Turn off the projector, allow it to cool down, and unplug the 
power cord.
2. Clean the air vent on the back of the projector. 
3. 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, 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.

Replacing the Lamp 
The projection lamp typically lasts for about 2000 hours of use 
(in high brightness mode) or 3000 hours (in low brightness mode). It 
is time to replace the lamp when: 
■The projected image gets darker or starts to deteriorate.
■The   lamp light is flashing orange. 
■The message Replace the Lamp appears on the screen when the 
lamp comes on. To maintain projector brightness and image 
quality, replace the lamp as soon as possible.
Contact your dealer or call Epson at (800) 873-7766 in the United 
States for a replacement lamp. Request part number V13H010L30.
In Canada, please call (800) 463-7766 to locate a dealer. 
Follow these steps to replace the lamp:
1. Press the P Power button twice to turn off the projector. When 
you hear the projector beep twice, unplug the power cord.
2. If the projector has been on, allow it to cool down for at least an

the screw holding the lamp cover (the lamp cover is located on top 
of the projector).
