Warning and Cautions on Installation
An optional ceiling mount is required when suspending the projector from
a ceiling.
s"Optional Accessories" p.242
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.
•Do not install in locations where it could be subject to salt damage, or in
locations subject to corrosive gas such as sulphuric gas from a hot spring.
Otherwise, the projector could fall due to corrosion. It could also cause
damage to the projector.
•A special method of installation is required when suspending the projector
from a ceiling (ceiling mount). If installation work is not carried out
correctly, the projector could fall down. This may result in injury or
accidents. Contact your local dealer or the nearest address provided in the
Epson Projector Contact List.
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,
lubricants, oils, and so on to prevent the screws from loosening.
Warning
•Failure to install the ceiling mount and projector may cause the projector to
fall.
After installing the specific Epson mount that supports your projector, make
sure you secure the projector and the mount using wire that is strong enough
to hold their weight.
•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.
•Be careful when handling the power cord. Otherwise, it could cause a fire or
electric shock. Note the following when handling the power cord.
- Do not plug multiple power cords in a single electric outlet.
- Do not plug in the power cord if there are any foreign substances, such
as dust, stuck to it.
- Make sure you insert the power cord all the way in.
- Do not plug in or unplug the power cord with wet hands.
- Do not pull the cord when unplugging the power cord. Make sure you
hold it by the plug.
•Do not use a damaged power cord. Otherwise, it could cause a fire or electric
shock. Note the following when handling the power cord.
- Do not alter the power cord.

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 +50˚C (Altitude of 0 to 1,500 m, no condensation)
0 to +45˚C (Altitude of 1,501 to 3,048 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.
sExtended - Operation - High Altitude Mode p.151
•The projector can be installed at any angle. There is no vertical or horizontal
limit to how the projector can be installed.
•You may need dedicated installation mounts to tilt and install the projector.
Contact a professional and prepare the mount.
•Plan so that the mount does not fall.
Safety Warning and Cautions
4

Attention
•Make sure you secure the following space around the projector so as not to
block the air exhaust vent and the 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 use two projectors at the same time when stacking two projectors
directly on top of each other. Install the projector so that there is no danger
that it will fall.
Attention
•Use commercially available M6 screws (up to a depth of 12 mm) to fix the
projector's ceiling mount fixing points and the mount at four points.
•When installing the projector with the air intake vent facing down, make sure
there is a gap of at least 10 cm between the projector and the floor and so
on. Make sure there is a space of 50 x 20 cm for the base so that the air
intake vent is not blocked.
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.
Wait for at least 20 minutes.
•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.

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. The powerful light emitted could
cause damage to eyesight. Take particular care when there are children
present. When turning on the projector at a distance using the remote
control, make sure there is no one looking into the lens.
•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.
•Do not open the projector's case. Never disassemble or remodel the projector.
There are high-voltage components inside the projector that could cause fire,
electric shock, or an accident.
•If an error occurs, disconnect the power cord from the electrical outlet, and
contact your local dealer or the nearest address provided in the Epson
Projector Contact List. If you continue using the projector as it is, it could
cause an electric shock, fire, or even damage to eyesight.
sEpson Projector Contact List
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
•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.
Safety Warning and Cautions

a
•About the LCD panel
- The LCD panel may contain pixels that are missing or appear bright all
the time. This is not a sign of an error.
- When a high-powered laser beams through the surface of the projection
lens even when it is not being used, it can cause a malfunction in the
LCD panel. Attach the lens cover when storing the projector.
•About the light source
The projector uses a laser as the light source. The laser has the
following characteristics.
- Depending on the surroundings, the brightness of the light source may
decline. The brightness declines a lot when the temperature gets too
high.
- The brightness of the light source declines the longer it is used. You can
change the relationship between usage time and decline in brightness in
Brightness Settings.
s"Relationship between Brightness Level and light source operation
time" p.80
•Light Source Calibration
- Whenever the usage time reaches 100 hours, calibration starts
automatically for the light source when the projector is turned off.
However, this does not start automatically when the projector is used
continuously for more than 24 hours, or when direct shutdown is used
regularly. Set Light Source Calibration in the scheduling function.
s"Scheduling Function" p.117
- When performing light source calibration, the difference between the
white balance and the brightness level for the light source is corrected.
