Maintaining the Projector
Your projector needs little maintenance. All you have to do is keep 
the lens clean. You may also need to clean the air filter and vent. A 
clogged air filter or vent can block ventilation needed to cool the 
projector.
The only parts you should replace are the lamp and air filter. If any 
other part needs replacing, contact your dealer or a qualified servicer.
This chapter covers the following:
■Cleaning the lens
■Cleaning the projector case
■Cleaning the air filter and vent
■Replacing the lamp and air filter
■Replacing the remote control batteries
■Transporting the projector
warning
Before you clean any part of 
the projector, turn it off and 
unplug the power cord. 
Never open any cover on the 
projector, except the lamp 
cover. Dangerous electrical 
voltages in the projector can 
injure you severely. Do not 
try to service this product 
yourself, except as specifically 
explained in this User’s 
Guide. Refer all other 
servicing to qualified service 
personnel.

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 a commercially available 
cloth for cleaning glasses.
Cleaning the Projector Case
Before you clean the case, 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, moisten a soft cloth with water 
and a neutral detergent. Then wipe the case.
caution
Do not use wax, alcohol, 
benzene, paint thinner, or 
other chemical detergents. 
These can damage the case.

Cleaning the Air Filter and Vent
Your projector includes an air filter to ensure the best performance. If 
dust collects on the air filter (on the bottom of the projector) or vent 
(on the front of the projector), clean them as described below. Dust 
clogs prevent proper ventilation and can cause overheating, which can 
damage the projector.
Follow these steps:
1. Turn off the projector and unplug the power cord.
2. To clean the intake vent and filter, use a small vacuum cleaner 
designed for computers and other office equipment. If you don’t 
have one, gently clean the vent with a soft brush (such as an 
artist’s paintbrush).
You can remove the air filter to clean both sides even if the 
projector is mounted on the ceiling. (See page 177).
3. If the dirt is difficult to remove or the filter is broken, replace the 
filter as described on page 177. Contact your dealer or call Epson 
at 800-GO-EPSON (800-463-7766) to obtain a new filter. 
note
To order replacement air 
filters, request part number 
V13H134A08. See page 13 
for ordering information.

Replacing the Lamp and Air Filter
The life span of the projection lamp is about 2500 hours if 
Brightness Control in the Settings menu is set to High (default), and 
3000 hours if 
Brightness Control is set to Low. See page 178 to 
check the lamp usage. 
It is time to replace the lamp when: 
■The projected image gets darker or starts to deteriorate.
■The message Replace the lamp appears on the screen when the 
lamp comes on and the lamp warning light   flashes orange. To 
maintain projector brightness and image quality, replace the lamp 
as soon as possible. 
■The lamp warning light   flashes red (the lamp is burnt out).
Contact your dealer or call Epson at 800-GO-EPSON 
(800-463-7766). Request part number V13H010L40.

When you get a replacement 
lamp for your projector, you

							Maintaining the Projector175
Follow these steps to replace the lamp and air filter:
1. Turn off the projector and unplug the power cord.
2. Let the projector cool for at least an hour (if it has been on). The 
lamp is extremely hot immediately after use. 
3. Loosen the lamp cover screw (you don’t need to remove it). Then 
slide the lamp cover to the side and lift it off of the projector. 
4. Loosen the two screws holding the lamp in place (you can’t 
remove them).
warning
Let the lamp cool fully 
before replacing it. 
In the unlikely event that 
the lamp has broken, small 
glass fragments may be 
present and should be 
removed carefully to avoid 
injury.
If the lamp is used after the 
replacement period has 
passed, the possibility that 
the lamp may break 
increases. When a lamp 
replacement message 
appears, replace the lamp 
with a new one as soon as 
possible, even if it is still 
working.
Loosen, but don’t 
remove these screws

Transporting the Projector
The projector contains many glass and precision parts. Follow these 
guidelines to prevent damage: 
■When shipping the projector for repairs, use the original 
packaging material if possible. If you do not have the original 
packaging, use equivalent materials, placing plenty of cushioning 
around the projector.
■When transporting the projector a long distance, first place it in a 
hard-shell shipping case, then pack it in a firm box with 
cushioning around the case. 
■Close the A/V mute slide (lens cover) to protect the lens. 
■If a CompactFlash card is installed, remove it from the projector. 
Make sure the card eject button is pushed all the way in, or it 
could be damaged.
