Safety Precautions for Installation
Warning
The setting plate is exclusively for mounting the projector on a wall. If anything other than
a projector is mounted, the weight may result in damage.
If this product falls, it could cause death or personal injury.
The installation work (wall mounting) should be performed by specialists who have tech-
nical knowledge and ability. Incomplete or incorrect installation could cause the product
to fall and cause personal injury or property damage.
Follow the instructions in this guide when installing this product.
If the instructions are not followed, this product may fall, resulting in personal injury or an accident.

Warning
Handle the power cord carefully.
Incorrect handling may cause fire or electric shock. Observe the following precautions when han-
dling:
•
Do not handle the power plug with wet hands.
•
Do not use a power cord that is damaged or modified.
•
Do not pull the power cord with too much force when routing the cable through the setting plate.
Do not install the setting plate in a place where it might be subjected to vibration or shock.
This could cause damage to the projector or mounting surface. If this product falls, it could cause
death or personal injury.
Install the setting plate so that it can sufficiently support the mass of the projector and
setting plate, and resist any horizontal vibration. Use M10 nuts and bolts.
Nuts and bolts smaller than M10 could cause the setting plateto fall. Epson accepts noresponsibility
for any damage or injury caused by lack of wall strength or inadequate installation.
The installation work should be performed by at least two qualified service personnel. If
you need to loosen any screws during installation, be careful not to drop this product.
If this product falls, it could cause death or personal injury.
When mounting this product on a wall, the wall requires enough strength to hold the
projector and the setting plate.
This product should be installed on a concrete wall. The maximum combined weight of the pro-
jector and the setting plate is approximately 13.5 kg (not including cables). Ensure the strength of
the wall before mounting this product on the wall. If the wall is not strong enough, reinforce the
wall before installation.
Inspect the setting plate on a regular basis to ensure there are no broken parts or loose
screws.
If any parts are damaged, stop using the setting plate immediately. If this product falls, it could
cause death or personal injury.
Do not disassemble or remodel this product.
There are numerous high-voltage sections inside the product that could cause a fire, electric shock,
or an accident.
Do not hang on this product or hang a heavy object on this product.
If this product falls, it could cause death or personal injury.
Do not use adhesives, lubricants, or oils to install or adjust the setting plate.
If you use adhesives to prevent the screws from loosening or things such as lubricants or oils on
the slide plate fixing part of the projector, the case may crack and cause the projector to fall,
resulting in personal injury or property damage.
Tighten all screws firmly after adjustment.
Otherwise, the product may fall and cause personal injury or property damage.
Never loosen the bolts and nuts after installation.
Confirm that the screws have not become loose on a regular basis. If you find any loose screws,
tighten them firmly. Otherwise, the product may fall and cause personal injury or property damage.
Route the cables so that they are not interfered with the nuts and bolts.
Incorrect handling of the cables may cause fire or electric shock.

Warning
When turning on the projector, do not look into the projection window.
This could cause damage to eyesight due to the powerful light emitted. 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 projection window.
When using the projector, do not place any objects or put your hand near the projection
window.
This area is dangerous as it reaches a high temperature due to the concentrated projection light.
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.
Avoid locations subject to high temperatures, such as close to heaters, and leave a gap of at least
50 cm between the wall and the air exhaust vent.
Do not use the projector in a location subject to combustible or explosive gas.
The projector may catch fire because of the high temperature of the lamp inside the projector.
If any abnormalities occur with this product, immediately disconnect the cables from the
product, and then contact your local dealer or the nearest Epson service call center.
Continuing to use the product in an abnormal condition could cause a fire, electric shock, or visual
impairment.
Caution
Do not install this product in a location where the operating temperature for your projector
model may be exceeded.
Such an environment may damage the projector.
Install this product in a place free from excessive dust and humidity to prevent the lens or
optical components from becoming dirty.
Do not use excessive force when adjusting this product.
This product may break, resulting in personal injury.
About This Installation Guide

Choosing an Installation Location
Projector installation location
•Carry out power supply wiring work for the installation location of the setting plate in advance.
•Install the projector away from other electric devices such as fluorescent lights or air conditioners. Some kinds of
fluorescent lights could interfere with the remote control of the projector.
•When installing the projector, make sure there is a gap of at least 50 cm from the wall to the projector's air exhaust
and intake vents on the left and right.
•When installing two or more projectors in parallel, make sure the temperature of the surrounding environment is
less than 35°C.
If the environment is too hot, the projector may overheat and the power may turn off without warning. When using
the projector in an environment of 35°C or more, install a partition to block the heat vented from the projector's air
exhaust vent. Make sure the partition is slightly larger than the exhaust vent (approx. 2 cm wider and taller), and then
install the partition 10 to 30 cm from the exhaust vent.
•It is recommended to keep connection cable length less than 20 meters to reduce external noise.
•We recommend using stick-on screens or board screens.
•Install the projector so that it is tilted at an angle of no more than ±3° vertically and horizontally in relation to the screen.
