Maintenance
This chapter explains the maintenance methods that are required to ensure a long projector service life. 
						

							Cleaning
116
Cleaning
You should clean the projector if it becomes dirty or if the quality of 
projected images starts to deteriorate.
Warning
Do not use sprays containing a flammable gas to remove dirt or dust which is 
adhering to parts such as the lens or filter of the projector.
This could cause a fire due to the high temperature of the lamps inside the unit.Cleaning the Projector's Surface
Clean the projector's surface by wiping it gently with a soft cloth.
If the projector is particularly dirty, moisten the cloth with water 
containing a small amount of neutral detergent, and then firmly wring 
the cloth dry before using it to wipe the projector's surface.
Caution
Do not use volatile substances such as wax, alcohol, or thinner to clean the projector's 
surface. The quality of the case may change or become discolored.Cleaning the Lens
Use a commercially available cloth for cleaning glasses to gently wipe the 
lens.
Caution
Do not rub the lens with harsh materials or subject the lens to shocks, as it can easily 
become damaged.
Cleaning the Air Filter
Clean the air filter and the air intake vent when the following message is 
displayed or the Filter indicator is flashing green.
"Time to clean the air filter."
"Clean or replace the air filter."
Caution
•If dust collects on the air filter it can cause the internal temperature of the projector 
to rise, and this can lead to problems with operation and shorten the optical engine's 
service life. Clean the air filter immediately when the message is displayed.
•If the air filter is stained yellow with tobacco smoke, it cannot be cleaned. In this 
case, replace it with a new air filter. sp.122
•Do not rinse the air filter in water. Do not use detergents or solvents.
•When using a brush for cleaning, use one with long soft bristles, and brush it lightly. 
If it is brushed too strongly, dust will be ground into the air filter and cannot be 
removed.
ProcedureA
Press the [
t] power button on the remote control or the 
back of the projector to turn off the projector’s power. After 
the confirmation buzzer beeps twice, disconnect the power 
cable.

							Replacing Consumables

Replacing ConsumablesReplacing the LampsLamp replacement period
It is time to replace the lamp when: 
•The message "Replace the lamp." is displayed at the lower left of the 
projection screen when you start projecting.
•The lamp indicator flashes orange.
Replace the lamp indicated by the flashing indicator, either lamp 1 or 2.•The projected image gets darker or starts to deteriorate.
Caution
•The lamp replacement message is set to appear after the following time periods in 
order to maintain the initial brightness and quality of the projected images.
PowerLite Pro Z8250NL/Z8255NL/Z8350WNL/Z8450WUNL/Z8455WUNL
When Power Consumption is set continually at Normal 1: About 2400 hours
When Power Consumption is set continually at ECO: About 3400 hours
PowerLite Pro Z8150NL: About 2400 hours
•Do not turn the projector on immediately after turning it off. Turning the projector 
on and off frequently may shorten the life of the lamps.
•If you continue to use the lamp after the replacement period has passed, the 
possibility that the lamp may explode increases. When the lamp replacement 
message appears, replace the lamp with a new one as soon as possible, even if it is 
still working.
•Depending on the characteristics of the lamp and the way it has been used, the lamp 
may become darker or stop working before the lamp warning message appears. We 
recommend that you keep a replacement lamp on hand at all times.q
We recommend that you clean the air filter whenever you replace the lamp. 
sp.116
Replace the air filter if it is discolored or if a message appears even after 
cleaning the air filter. sp.122
How to replace the lamp
The lamps can be replaced even when the projector is suspended from a 
ceiling.
Warning
•When replacing a lamp because it has stopped illuminating, there is a possibility 
that the lamp may be broken. If replacing the lamp of a projector that is installed on 
the ceiling, you should always assume that the lamp is broken, and you should stand 
to the side of the lamp cover, not underneath it. Remove the lamp cover gently. 
						

							Replacing Consumables
120
•Never disassemble or remodel the lamp. If a remodeled or reassembled lamp is 
installed into the projector and used, it could cause a fire, electric shock, or an 
accident.
Warning
Wait until the lamps have cooled down sufficiently before removing the lamp cover. If 
the lamp is still hot, burns or other injuries may result. It takes about one hour after 
the power has been turned off for the lamp to be cool enough.
ProcedureA
Press the [
t] power button on the remote control or the 
back of the projector to turn off the projector’s power. After 
the confirmation buzzer beeps twice, disconnect the power 
cable.
B
Wait until the lamps have cooled down sufficiently before 
removing the lamp cover on the back of the projector.
Pinch the tabs on the front of the lamp cover together to release the 
lock. When the lock releases, pull the cover straight out.
C
Pull up the lock lever for the lamp you want to replace and 
pull the lamp straight out.
If the lamp is cracked, replace it with a new lamp, or contact Epson.
