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.

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), clean it as 
described on page 123. 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 12 
for ordering information.

Follow these steps:
1. Turn off the projector and unplug the power cord.
2. Grip the air filter cover tab and remove the air filter cover as 
shown.
3. Place your finger into the groove and remove the air filter as 
shown.
4. With the front of the air filter facing down, tap it four or five 
times to shake off the dust. Turn it over and tap the other side in 
the same way to shake off the dust. 
						

							124Maintaining the Projector5. 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.
7. Slide the air filter cover in until you feel resistance.
8. If the dirt is difficult to remove or the filter is broken, replace the 
filter as described on page 125. Contact your dealer or call Epson 
at 800-GO-EPSON (800-463-7766) to obtain a new filter.

Replacing the Lamp
The life span of the projection lamp is about 2000 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 130 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 light flashes orange. To 
maintain projector brightness and image quality, replace the lamp 
as soon as possible. 
note
Turn off this product when 
not in use to prolong the life 
of the projector.  
						

							Maintaining the Projector127
You may also need to replace the lamp if the   Lamp light flashes 
red. See page 135.
Contact your dealer or call Epson at 800-GO-EPSON 
(800-463-7766). Request part number V13H010L47 (G5150NL) or 
V13H010L46 (G5350NL and G5200WNL).
Follow these steps to replace the lamp:
1. Turn off the projector and, after the projector beeps twice, 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 screws (you don’t need to remove them). 
Then remove the lamp cover.
Lamp lightwarning
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.
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. 
						

							128Maintaining the Projector4. 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.) 
7. Once the lamp is fully inserted, tighten its screws.
Loosen, but don’t 
remove these screws
note
The lamp(s) in this 
product contain mercury. 
Please consult your state and 
local regulations regarding

note
The information displayed 
depends on the input signal 
currently selected.
caution
When replacing batteries, 
take the following 
precautions:
■Replace the batteries as 
soon as they run out. If the 
batteries leak, wipe away 
battery fluid with a soft 
cloth. If fluid gets on your 
hands, wash immediately.
■Do not expose batteries to 
heat or flame.
■Dispose of used batteries 
according to local 
regulations.
■Do not use batteries other 
than those specified in this 
User’s Guide and do not 
use batteries of different 
types or mix old and new 
batteries.
■Keep these batteries out of 
the reach of children. 
Batteries are choking 
hazards and are very 
dangerous if swallowed.
