Cleaning the Lens 
Clean the lens whenever you notice dirt or dust on the surface. 
❏ Use a canister of compressed air to remove dust. 
❏ To remove dirt or smears on the lens, use lens-cleaning 
paper. If necessary, moisten a soft cloth with lens cleaner and 
gently wipe the lens.
Caution:
Do not use glass cleaner to clean the lens.
Cleaning the Projector Case
Before you clean the case, first turn off the projector and unplug 
the power cord. 
❏ To remove dirt or dust, wipe the case with a soft, dry, 
lint-free cloth. 
❏ To remove stubborn dirt or stains, wipe the case with a soft 
cloth moistened with a mild detergent. 
Caution:
Do not use wax, alcohol, benzene, paint thinner, or other 
chemical detergents. These can damage the case.
Cleaning and Replacing the Air Filter
Clean the air filter and air vents on the bottom of the projector 
after every 100 hours of use. If not cleaned periodically, they 
can become clogged with dust, preventing proper ventilation. 
This can cause overheating and damage the projector. 
1. Turn off the projector, allow it to cool down, and unplug the 
power cord.
2. Turn the projector upside down.
Use a small vacuum cleaner designed for computers and 
other office equipment. If you don’t have one, use a very soft 
brush (such as an artist’s brush).
If dirt is difficult to remove or the filter is torn, replace it. 
Contact your dealer or call Epson at (800) 873-7766 
to obtain a new set (part number V13H134A08). In 
Canada, please call (800) 463-7766 to locate a dealer. 
Note:
When you get a replacement lamp for your projector, a new air 
filter is included. Replace the filter when you replace the lamp.
