with a soft, dry, lint-free cloth.
■To remove stubborn dirt or stains, 
moisten a soft cloth with water and a 
neutral detergent. Then wipe the case 
and dry it with a dry cloth.

thinner, or other chemical detergents. These 
can damage the case.
Cleaning and Replacing the Air Filter
Your projector includes an air filter to ensure the best performance. If dust collects on the air 
filter, clean it as described below. Dust clogs prevent proper ventilation and cause overheating 
and damage to the projector.

cools down.
2. Turn off the projector using the power switch on the back.
3. Unplug the power cord and disconnect any cables.
4. Turn the projector over (unless it’s ceiling mounted).
5. Push down on the tabs on the filter cover to remove it.
6. Remove the air filter as shown. 
						

							52Maintenance
7. Gently tap both sides of the air filter against a hard surface 
four or five times to remove loose dust from the air filter.
Note: Do not tap the filter too hard. This can cause it to bend 
or break.
8. Use a small vacuum cleaner that is designed for computers 
and other office equipment to remove any remaining dust 
from the surface of the filter. If you don’t have one, gently 
clean the filter using a very soft brush (such as a clean 
artist’s paintbrush).
If the dirt is difficult to remove or the filter is broken, 
replace it. You can purchase air filter part number V13H134A21 from an authorized 
Epson reseller. To find the nearest reseller, please call 800-GO-EPSON (800-463-7766). 
To purchase online, visit www.epsonstore.com (U.S. sales) or www.epson.ca (Canadian 
sales).

the projector until it clicks into place.
