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
■Replacing the air filter
■Replacing the lamp
■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. 
						

							134Maintaining the Projector
Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface.
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 and firmly wring the cloth dry. Then wipe 
the case.
Cleaning the Air Filter 
Your projector includes an air filter to ensure the best performance. If 
dust collects on the air filter (on the side of the projector), you see a 
message on the screen telling you to clean the filter, or the   
Temp 
light flashes green, clean the filter as described on page 135. Dust 
clogs prevent proper ventilation and can cause overheating, which can 
damage the projector.
caution
Do not rub the lens with 
harsh materials or subject 
the lens to shocks, as it can 
easily become damaged.
caution
Do not use wax, alcohol, 
benzene, paint thinner, or 
other chemical detergents. 
These can damage the case.
note
To order replacement air 
filters, request part number 
V13H134A17. See page 15 
for ordering information.

times to shake off the dust. Turn it over and tap the other side in 
the same way to shake off the dust.
5. To clean any dust remaining on the air filter, use a small vacuum 
cleaner designed for computer and other office equipment to 
clean the front. If you don’t have one, gently clean the vent with a 
soft brush (such as an artist’s paintbrush).
6. Insert the air filter back into the holes in the cover, then press it 
firmly into place.

3000 hours if 
Power Consumption is set to ECO. 
See page 142 to check the lamp usage. 
note
The air filter contains 
Polypropylene. Dispose of 
used air filters properly in 
accordance with your local 
regulations.
note
Turn off this product when 
not in use to prolong the life 
of the projector.
Do not turn the projector on 
immediately after turning it 
off. Turning the projector on 
and off frequently may 
shorten the life of the lamp. 
						

							Maintaining the Projector139
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.
■The  Lamp light flashes orange.
To maintain projector brightness and image quality, replace the lamp 
as soon as possible. 
You may also need to replace the lamp if the   
Lamp light flashes 
red. See page 147.
Contact your dealer or call Epson at 800-GO-EPSON 
(800-463-7766). Request part number V13H010L62 
(G5450WUNL/G5550NL) or V13H010L63

clean the air filter whenever 
you replace the lamp.
Lamp light
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 projector has 
been installed on the ceiling, 
you should stand to the side 
of the lamp cover, not 
underneath it.
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. 
						

							140Maintaining the Projector3. Loosen the lamp cover screws (you don’t need to remove them). 
Then remove the lamp cover.
4. Loosen the two screws holding the lamp in place (you can’t 
remove them).
5. Hold the lamp as shown and pull it straight out.
 
6. Gently insert the new lamp. (If it doesn’t fit easily, make sure it is 
facing the right way.) 
note
Even when the lamp cover is 
removed, it is still attached 
to the projector to prevent it 
from falling when the 
projector is mounted on the 
ceiling.
Loosen, but don’t 
remove these screws
note
The lamp(s) in this
