Warning and Cautions on Installation
An optional ceiling mount is required when suspending the projector from
a ceiling.
s"Optional Accessories" p.217
Warning
•Do not use or install the projector where it may be subject to water or rain,
or high humidity, such as outdoors, in a bathroom, or shower room, and so
on. Otherwise, it could cause a fire or electric shock.
•A special method of installation is required when suspending the projector
from a ceiling (ceiling mount). If installation work is not carried out

sEpson Projector Contact List
•If you use adhesives on the ceiling mount fixing points to prevent the screws
from loosening, or if you use things such as lubricants or oils on the
projector, the projector case may crack causing it to fall from its ceiling
mount. This could cause an accident or injury to anyone under the ceiling
mount.
When installing or adjusting the ceiling mount, do not use adhesives to
prevent the screws from loosening and do not use oils or lubricants and so
on.
•Do not cover the projector's air intake vent or air exhaust vent. If either of
the vents are covered, the internal temperature could rise and cause a fire.
•Do not place flammable objects in front of the lens. If you set the schedule to
turn on the projector automatically, any flammable objects placed in front of
the lens could cause a fire.
•Do not tie the power cord and other connection cables together. Otherwise, it
could cause a fire.
•Only use the specified power-supply voltage. Otherwise, it could cause a fire
or electric shock.

Caution
Do not place the projector on an unstable surface, such as on an unstable table
or tilted surface. When projecting vertically, install the projector appropriately
to prevent the projector from falling.
Otherwise it may cause an injury.
Attention
•Do not install the projector in a location that is subject to vibration or
shock.
•Do not install the projector near a high-voltage line or object that generates
magnetism. Otherwise the projector may not work correctly.
•Do not use or store the projector in a location that is subject to extreme
temperatures. Also, avoid sudden temperature changes.
Make sure you use or store the projector in a place that is within the
following operating or storage temperature ranges.
- Operating temperature range
0 to +45˚C (Altitude of 0 to 1,500 m, no condensation)
0 to +40˚C (Altitude of 1,501 to 3,048 m, no condensation)
0 to +35˚C (Altitude of 3,049 to 5,000 m, no condensation)
- Storage temperature range: -10 to +60˚C (No condensation)
•When using at an altitude that exceeds 1,500 m, set High Altitude Mode to
On.

Attention
•When projecting with the projector tilted, do not tilt it at more than the
specified angle. This may cause malfunctions or accidents to occur.
Angle of tilt
Vertical: Can be installed at any angle in a complete 360 degrees.
90
45
0
135
180
-135
-90
-45
Horizontal: Can be tilted within the range (about ±1.3 degrees) of expansion
and contraction for the rear feet. The feet can be attached and removed. Note
that the feet will detach if they are extended more than 10 mm.
•Once installation is complete, make sure you set the Direction. If it is not
set, the projector does not cool down correctly, and the lamps may
deteriorate.
s"Setting the direction" p.28
•Using the projector at an improper angle or setting the Configuration menu
incorrectly causes malfunctions and shortens the operating life of optical
parts.
Attention
•Make sure there is a gap as shown in the following illustration between the
wall and the air exhaust vent and the air intake vent.
Air exhaust vent Air intake vent
•When setting up multiple projectors, make sure there is a gap of at least
50 cm between the projectors. Also, make sure that the heat from the air
exhaust vent does not go into the air intake vent.
•Do not place the projector directly on top of another projector.
a
•We recommend setting the focus, zoom, and lens shift at least
20 minutes after you start the projection, because images are not
stable right after turning on the projector.
•When adjusting the image height with the vertical lens shift, adjust
by moving the image from the bottom to the top. If it is adjusted
from the top to the bottom, the image position may move down
slightly after adjusting.
Safety Warning and Cautions

Notes on portrait installation
A dedicated mount is required for portrait installation. Contact a
professional and prepare the mount.
Attention
•Plan so that the mount does not fall.
•Use commercially available M6 screws (up to a depth of 12 mm) to fix the
ceiling mount fixing points of the projector and the mount at four points
(you do not need to remove the feet of the projector).
Attention
•Make sure you install the projector with the air intake vent facing down. If
the air intake vent is facing up, the projector does not cool down correctly,
and it may cause a malfunction.
Angle of tilt
Using the projector at angles not shown in the illustrations above may
damage it or cause an accident.
•Make sure that you install the projector with the air intake vent facing down
and that there is a gap at least as wide as shown in the following illustration
between the projector and the floor and so on. Make sure there is a gap of
400 x 200 mm for the base so that the air intake vent is not blocked.
•Once installation is complete, make sure you set the Direction. If it is not
set, the projector does not cool down correctly, and the lamps may
deteriorate.
s"Setting the direction" p.28
•Do not use lamps that have been used for about 2000 hours or more at
normal installment. This may cause the projector to malfunction or cause the
lamps to deteriorate.

Warning and Cautions on Usage
Warning
•Do not cover the projector's air intake vent or air exhaust vent. If either of
the vents is covered, the internal temperature could rise and cause a fire.
•Do not look into the lens while projecting.
•During projection, do not block the light from the projector with the lens
cover (removable) or a book and so on.
If the light from the projector is blocked, the area on which the light shines
becomes hot which could cause it to melt, burn, or start a fire. Also, the lens
may get hot due to the reflected light which could cause the projector to
malfunction. To stop projection, use the A/V Mute function, or turn off the
projector.
•A mercury lamp with high internal pressure is used as the projector's light
source. If the lamp is subjected to vibrations, shocks, or if it is used for an
overly extended length of time, the lamp may break or it may not turn on. If
the lamp explodes, gases may escape and small fragments of glass may be
scattered which could cause an injury. Be sure to observe the instructions
below.
- Do not disassemble or damage the lamp or subject it to any impacts.
- Do not bring your face close to the projector while it is in use.
- Particular care should be taken when the projector is installed to a
ceiling, as small pieces of glass may fall down when the lamp cover is
removed.
When cleaning the projector or replacing the lamp yourself, be very
careful not to allow such pieces of glass to get into the eyes or mouth.
If the lamp breaks, ventilate the area immediately, and contact a doctor if any
fragments of broken glass are inhaled or get into the eyes or mouth. In
addition, consult your local regulations regarding proper disposal and do not
place in the trash.
Caution
Do not place objects that may become warped or otherwise affected by heat
near the air exhaust vent and do not put your face or hands near the vent
while projection is in progress.
Attention
•Do not repeatedly turn off the power and immediately back on. Turning the
power on and off frequently may shorten the lamp's operating life.
•Only remove the lens unit when necessary. If dust or dirt enter the projector,
projection quality deteriorates and it could cause a malfunction.
•Try not to touch the lens section with your hand or fingers. If fingerprints or
oils are left on the surface of the lens, projection quality deteriorates.
•Store the projector with the lens unit installed.
If the projector is stored without the lens unit, dust and dirt may get inside
the projector and cause malfunctions or lower the quality of projection.
•When storing, make sure you remove the batteries from the remote control.
If the batteries are left in the remote control for an extended period of time,
they may leak.

as follows.
Caution
Do not carry the projector by one person. Two people are needed to unpack or
carry the projector.
Attention
•Moving Nearby
- Turn off the power to the projector and disconnect all cables.
- Attach the cover to the lens.
•When Transporting
After checking the points in "Moving Nearby", prepare the following and then
pack up the projector.
- Remove the lens unit if an option lens is installed.
- If the projector does not have a lens, attach the cover that was on the
lens mount when you purchased the projector.
- Attach the lens if the projector has a built-in lens. Upon purchase,
attach the protective pad that is attached around the lens unit.
- Move the lens position to the home position.
s"Adjusting the Position of the Projected Image (Lens Shift)"
p.33
- Enclose the projector securely in packaging material to protect it from
shock, and place it into a strong cardboard container. Be sure to notify
the carrier company that it is precision equipment.
