clogged air filter or vent can block ventilation needed to cool the 
projector.

other part needs replacing, contact yo ur 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
■Transporting the projector

the projector, turn it off and

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.
To remove dirt or smears on the lens, use lens-cleaning tissue. If 
necessary, moisten a soft cloth with lens cleaner and gently wipe the 
lens.
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,

Maintaining the Projector105
Cleaning the Air Filter and Vent
Your projector includes an air filter to ensure the best performance. If 
dust collects on the air filter or vent, clean them as described below. 
Dust clogs prevent proper ventilat ion and can cause overheating and 
damage the projector. 
If you see the following message, clean the air filter immediately.
The projector is overheating. Make sure nothing is blocking the 
air vent, and clean or replace the air filter.
1. Turn off the projector. Wait for the  Ppower light to stop 
flashing, then 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. For instructions, 
see page 110.
3. If the dirt is difficult to remove  or the filter is damaged, or if the 
message appears again after cleaning , replace the filter as described 
on page 110. Contact your dealer or call Epson at 
800-GO-EPSON (800-463-7766)  to purchase a new filter. 
note
To order replacement air 
filters, request part number 
V13H134A22. See page 13 
for ordering information.
The exhaust 
vent is on the 
other side of 
the projector 
						

							
106Maintaining the Projector
Replacing the Lamp and Air Filter
The life span of the projection lamp is about 5000 hours if 
Brightness Control in the Setting menu is set to High (default), and 
6000 hours if 
Brightness Control is set to Low.
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 V13H010L50. 
Replacing the Lamp
1. Turn off the projector.
2. When the  Ppower light stops flashing, unplug the power cord.
3. Let the projector cool for at least an hour (if it has been on). The  lamp is extremely hot immediately after use. 
note
When you replace the lamp 
for your projector, you 
should also replace the filter.
To check how long the lamp 
has been in use, see 
page 119.
Turn off this product when 
not in use to prolong the life 
of the projector. 
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.
