Asking for installation
To view images projected by the ceiling-mounted 
projector from the front:
When the projector is installed on the ceiling, the 
special ceiling mount bracket, which is separately 
sold, is required. Be sure to ask a certifi ed installation 
specialist for installation of the projector. Contact your 
dealer for details. 
•  Mitsubishi assumes no responsibilities for any 
damage caused by use of other manufacturer's 
ceiling bracket and by inadequate installation 
conditions even within the warranty period. 
•  When installing the projector on the ceiling, set 
IMAGE REVERSE in the INSTALLATION menu to 
MIRROR INVERT. 
•  Ask your installation specialist to provide a breaker. 
When you do not use the projector, be sure to shut 
down the main power by the breaker. 
•  When the projector is installed on the ceiling, 
projected images may appear darker than those 
projected when the projector is installed on the 
fl oor. This symptom is not a malfunction. 
•  Do not install the projector where the exhaust vents 
are exposed to air emitted by an air conditioning. 
Such installation may cause a breakdown. 
•  Do not install the projector near a fi re alarm 
because it emits hot air from its exhaust vents. To view images projected on the translucent screen 
from behind: 
Be sure to ask a certifi ed installation specialist for 
installation of the projector. Contact your dealer for 
details. 
•  To view images projected from behind the screen, 
set IMAGE REVERSE in the INSTALLATION menu 
to MIRROR.

Filter cover
(a)
This projector has a fi lter cover (fi lter) for keeping dust out. When using the projector in a dusty place, attach this fi lter 
cover. 
Installation
Before installing this  lter to the projector, be sure 
to unplug the projector from the outlet.
1.  Fit three hooks of the fi lter cover into the projector.
2. Push the fi lter cover in the direction of the arrow.
•  If you use excess force to push the fi lter cover, 
the hooks may be damaged.
3.  Tighten the attachment screw (a) fi rmly. 
Cleaning
Before cleaning, be sure to turn off the main power switch and unplug the projector from the outlet.
•  Clean the fi lter frequently (at least once a month). When dust accumulates on the fi lter at the air inlet, the 
temperature inside the projector may rise abnormally high, causing damage to the internal parts and reducing 
the lifetime of the panel.
•  In case of any abnormality including an abnormal rise of the inside temperature, the projector may automatically 
turn off and go into the standby mode where the light source lamp is turned off in order to protect its internal 
parts.
Cleaning the  lter
1.  Remove the screw (a) from the fi lter cover.
•  Be careful not to lose the screw.
2.  Move the fi lter cover in the direction of the arrow.
3.  Release three hooks and remove the fi lter cover from 
the projector.
•  If you use excess force to pull the fi lter cover, the 
latches may be damaged.
4.  Remove the holder that is retaining the fi lter while 
pushing the tab of the holder in the direction of the 
arrow.
5.  Remove the fi lter from the fi lter cover.
6.  Clean dirt and dust adhering to the fi lter using a 
vacuum.
•  If stubborn stains persist, wash the fi lter with diluted 
detergent, rinse with water, and dry well.
7.  Attach the fi lter to the fi lter cover.
•  Make sure that the fi lter is positioned correctly.
8.  Fit and push the holder as far as it will go and press it in 
the direction of the arrow to install.
9.  Fit three hooks of the fi lter cover into the projector.
10. Push the fi lter cover in the direction of the arrow.
•  If you use excess force to push the fi lter cover, the 
hooks may be damaged.
11. Tighten the attachment screw (a) of the fi lter cover 
fi rmly. •  Don’t use any other fi lters than that designed for this projector. 
•  If you are disturbed by the light emitted from the side of the projector, attach 
the fi lter to block the light. Further, if you are disturbed by the light emitted 
from the hole of theft-proof lock, put the supplied cap on the hole.

Replacing the lamp
This projector is equipped with a lamp to project images. This lamp is a consumable. It may burn out or its brightness 
may decrease during use. In such cases, replace the lamp with a new one as soon as possible. Be sure to replace the 
lamp with a new lamp separately sold that is exclusive to this projector. Contact your dealer for purchase of the lamp. 
WARNING:
•  Be careful not to drop the lamp fi xing screws into the inside of the projector. Don’t put a metal piece or fl ammable 
object into the projector. Using the projector with any foreign object present inside may result in electric shock or 
fi re. When you can’t remove the foreign object from the inside, contact your dealer for removal. 
•  Be sure to install the lamp securely. When the lamp isn’t installed properly, it won’t illuminate. Improper installation 
may also result in fi re.
•  Don’t shake the removed lamp or don’t lift it above your face. You may be injured in your eye by fl ying or falling 
glass fragments.
•  Don’t replace the lamp immediately after use because the lamp cover is very hot. You may get burned. Turn off the 
power using the POWER button. After the lamp goes out, wait about two minutes until the intake and exhaust fans 
for cooling the lamp stop rotating. Then unplug the power cord, and wait at least one hour to allow the lamp to 
cool down enough to the touch. 
Interval of lamp replacement
The recommended interval of lamp replacement is about 3000 hours*
1 *2 of consecutive use. Such interval differs 
depending on the operating environment and may be shorter than 3000 hours*1 *2. Decrease in luminescence and/or 
color brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds 2250 hours*1, 
the indicator will blink alternately between green and red (while the lamp is lit; when the lamp is not lit, the indicator 
will be lit red only) and the lamp replacement message will appear on the screen for one minute everytime the lamp is 
turned on. When the lamp has been used for about 2850 hours*
1, the replacement message (LAMP EXCHANGE) will 
appear on the screen for one minute every 20 hours*1 thereafter.
When the lamp operation time exceeds 3000 hours*
1 *2, the projector automatically shuts off and can’t be used 
until the lamp is replaced and the lamp operation time is reset.

Caution:
•  Don’t remove the lamp for any purpose other than replacement. Unnecessary removal of the lamp may result in a 
breakdown.
•  This projector uses a high-pressure mercury lamp as the light source. The high-pressure mercury lamp may 
explode or fail to illuminate permanently because of an impact, scratch, or deterioration through use. The period 
of time until explosion or permanent failure to illuminate varies considerably from lamp to lamp, depending on 
operation conditions. Therefore, the lamp may explode soon after the start of use. 
•  The possibility of explosion of the lamp increases if you use it beyond its replacement period. When the instruction 
of lamp replacement appears, replace it with a new one immediately even if the lamp is still lighting normally. 
•  When the high-pressure mercury lamp explodes, glass fragments will scatter inside or outside the lamp box and 
the gas charged inside the lamp will diffuse inside or outside the projector. The gas inside the lamp contains 
mercury. Be careful not to breathe it or avoid it from entering your eye or mouth. If you should breathe it or if it 
should enter your eye or mouth, see a doctor immediately.
•  In the event that the high-pressure mercury lamp exploded, glass fragments may have been scattered inside the 
projector. Ask your dealer to replace the lamp and to inspect the inside of the projector. When you clean or replace 
the lamp by yourself, be sure to hold the handle of the lamp. You may get injured by glass fragments. 
•  Don’t replace the lamp while the projector is installed on the ceiling. Glass fragments may fall from the projector, 
entering your eye or mouth causing injury. 
•  When placing the projector upside down to replace the lamp or conduct maintenance, ensure that the projector is 
securely placed before working with it.
