•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 to

prevent the screws from loosening and do not use oils or lubricants and so

on.

•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 is covered, the internal temperature could rise and cause a fire.

Safety Warning and Cautions

temperatures. Also, avoid sudden temperature changes.

Make sure you maintain the operating or storage temperature ranges.

s"Projector General Specifications" p.245

•Do not install the projector in direct sunlight. If the projector is in direct

sunlight, the internal temperature increases, which could cause parts such as

the surface of the projection lens or the built-in camera to deteriorate.

•When installing the projector in an environment in which a high-powered

laser beam is being used, make sure it is installed so that the laser beam does

not hit the surface of the projection lens.

•When using at an altitude that exceeds 1,500 m, set High Altitude Mode to

On.

sExtended - Operation - High Altitude Mode p.142

•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 specialist and prepare the mount.

Safety Warning and Cautions

Attention

•Plan so that the mount does not fall.

•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.

•Note the following points when projecting from projectors directly on top of

another.

- Do not stack three or more projectors.

- Tilt the projector within the extendable range of the feet.

- Install the projector so that it does not fall over.

- When using the projector's feet, make sure that all of the feet are firmly

placed on the projector below.

Attention

•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 20 x 20 cm for the base so that the air

intake vent is not blocked.

•When using the ceiling mount or the portrait mount, use commercially

available M6 screws (up to a depth of 27 mm) to fix the projector's ceiling

mount fixing points and the mount at four points.

Safety Warning and Cautions

Attention

•When using a clamp to attach the projector to an aluminum truss, attach the

clamp to at least four points so that it is symmetrical with the eight screw

holes for the clamp. When installing using four points, use the following

screw hole combinations. The M6 screws for the clamp must be longer than

10 mm (with a max of 27 mm). You cannot install if the distance between

the center of the aluminum truss pipe and the center does not match the

distance between the screw holes.

s"Appearance" p.250

•When installing the projector in a high location such as on a wall, hanging

from a ceiling, or an aluminum truss, make sure you take measures against

the projector falling such as attaching a commercially available drop-

prevention wire to the mounting section.

•We recommend setting the focus, zoom, and lens shift at least 30

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.

Warnings and Cautions on Lifting

Caution

•Use the four eye bolts installed on the same surface of the projector to lift

it.

•Only use the eye bolts when temporarily transporting the projector and not

for permanent installation. The projector could be damaged or could

malfunction.

•Do not lift the projector with the front/back/side of the projector facing

up.

•Make sure that the angle when lifting is 60 degrees or more.

Safety Warning and Cautions

Attention

Use four commercially available eyebolts M6 (ankle length 12 to 27 mm) to

attach to the four eye hole screw holes.

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 place a cloth or any paper under the projector. The cloth or paper

could be sucked up by the Air intake vent on the bottom of the projector

during projection causing the internal temperature to rise which could start 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. Also, do not look through the lens using optical equipment such as a

magnifying glass or telescope. 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 Shutter 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

Safety Warning and Cautions

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.

•Special techniques are required to install and remove the interface board, so

make sure you contact a specialist. Otherwise, unexpected malfunctions could

occur due to static electricity and so on.

•Turn off the projector and unplug the power plug from the outlet before

installing/removing the interface board.

Attention

•When you purchase the projector, a protective cap is installed in the lens unit

installation section. Install the protective cap when the lens unit is not

installed. If dust or dirt enter the projector, projection quality deteriorates

and it could cause a malfunction.

•Make sure the slot cover or the interface board is always installed in the slot.

If dust or dirt enter the projector, it could cause a malfunction.

•When a high-powered laser beams through the surface of the projection lens,

it can cause a malfunction in the LCD panel. If the laser can beam through

the surface of the projection lens, block the laser beam with non-permeable

or incombustible aluminum foil or metal plates such as iron to protect the

projection lens. You can also use the projector's Shutter function to prevent

the LCD panel from being damaged by laser light.

s"Hiding the Image Temporarily (Shutter)" p.101

•When high-powered laser beams enter the built-in camera, they can cause a

malfunction. Make sure you attach the protection plate to the built-in

camera.

s"Rear/Side" p.18

Attention

•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.

•If you continue to project while the surface of the lens is dirty, projection

quality deteriorates. Make sure you clean the lens.

s"Cleaning the Lens" p.202

•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.

•When using the projector in smoky environments such as at events and so

on, make sure you replace the air filter after approximately 240 hours of use.

(This is a guideline when using the projector in an environment with an

atmospheric concentration of ondina oil of approximately 0.000000013%. The

air filter replacement time may be shorter depending on the operating

environment.)

Using the projector in a smoky environment may cause the filter's dust

collection function to decline and dust may adhere to the inside of the

projector or the power supply; this may cause a malfunction to occur.

s"Replacing the Air Filter" p.206

Safety Warning and Cautions

•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.

•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 operation time and decline in

brightness in Brightness Settings.

s"Relationship between Brightness Level and light source operation

time" p.75

•About light source calibration

-WhenRun Periodically is set to On for light source calibration, every

time the operation time reaches 100 hours, calibration starts

automatically for the light source when the projector is turned off.

However, light source calibration does not start automatically in the

following situations.

•Within 30 minutes of turning on the projector

•When using the Shutter function

•Within 30 minutes of releasing the Shutter function

•When the projector is used continuously for over 24

hours

•When using direct shutdown

- When performing Light Source Calibration, the differences in the

White Balance and the Brightness Level for the light source are

corrected.
