Installing the air filter unit while it is wet will result in 
electric shock or malfunction.
Note
Be sure to install the air filter properly. If the projector 
 
z
is operated without the air filter installed, the projector 
will shut off after ten minutes to prevent damage from 
incoming dirt and dust. (In such cases, the remaining 
time before shutdown is displayed in one-minute 
increments.)
Replace the air filter with a replacement filter unit (ET-
 
z
EMF100) when cleaning fails to remove dirt or dust, or 
when the air filter unit breaks.
Air filter replacement is recommended after cleaning the 
 
z
unit two times.
The dust-proof properties may reduce after each 
 
z
cleaning.

JLamp unit
The lamp unit is a consumable component. You can check the total usage time using STATUS in the 
PROJECTOR SETUP menu on page 56.
It is recommended to ask an authorized engineer to replace the lamp unit\
. Contact your dealer.
Consult your dealer to purchase a replacement lamp unit (ET-LAF100A, dealt as a service component).
CAUTION:
■ Do not replace the lamp unit when it is hot. (Wait at least one hour after use.)
The inside of the cover can become very hot, take care to avoid burn inj\
uries.
Notes on the replacement of the lamp unit 
J
The luminous source of the lamp is made of glass and may burst if  
z
you hit it against a hard surface or drop it.  
Please handle with care.
A Phillips screwdriver is required for replacement of the lamp unit.
 
z
When replacing the lamp unit, be sure to hold it by the handle. 
z
Hold the lamp unit horizontally while replacing it to prevent fragments \
 
z
of glass from scattering, in case the lamp breaks. When the projector 
is mounted on a ceiling, do not work directly under the projector or put 
your face close to the projector. Pull the old lamp unit out horizontally.
The lamp contains mercury. Consult your local municipality or your 
 
z
dealer about correct disposal of used lamp units.
Attention
Do not use other than designated lamp units.
 
z
The part numbers of accessories and separately sold components are subje\
ct to change without notice.
 
z
When to replace the lamp unit 
J
The lamp unit is a consumable component. Brightness decreases according to duration of usage, so periodical 
replacement of the lamp unit is necessary. 6000 hours of use is a rough guideline for replacement. However, 
a lamp unit may not light before 6000 hours of use, depending on individ\
ual lamp, usage, and environmental 
conditions. It is recommended to prepare spare units in advance. The risk of the lamp bursting increases after 
6000 hours of use. To prevent this, the projector will automatically turn the lamp off approximately ten minutes 
after it is turned on in such cases. It is recommended that you replace \
the lamp unit before this occurs.
