Warning
You must install a ceiling mount when suspending the projector from a ceiling.
If you do not install the projector correctly, it could fall and cause damage or
injury.
Do not use adhesives on the ceiling mount fixing points to prevent the screws
from loosening, or use lubricants, oils, or similar substances on the projector; the
projector case may crack causing it to fall from its ceiling mount. This could
cause serious injury to anyone under the ceiling mount and could damage the
projector.
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 mount to all of the projector's ceiling mount fixing points.
Also, secure the projector and the mounts using wire that is strong enough to
hold their weight.
Do not install the projector in a location subject to high levels of dust or
humidity, or in a location subject to smoke or steam. Otherwise, it could cause a
fire or electric shock to occur. The projector's case could also deteriorate and be
damaged causing the projector to fall from the mount.
Examples of environments that could cause the projector to fall due to case
deterioration
Locations subject to excessive smoke or airborne oil particles, such as factories
or kitchens
Locations containing volatile solvents or chemicals, such as factories or
laboratories
Locations where the projector could be subjected to detergents or chemicals,
such as factories or kitchens
Locations in which aroma oils are often used, such as relaxation rooms
Near devices that produce excessive smoke, airborne oil particles, or foam at
events
Warning
Do not cover the projector's air intake or air exhaust vents. If the vents are
covered, the internal temperature could rise and cause a fire.
Do not use or store the projector in locations where it will be subject to dust or
dirt. Otherwise, the quality of the projected image may decline. If the lens or air
filter gets dusty, it may result in a malfunction or fire.
Do not install the projector on an unstable surface or in a location beyond the
weight specifications of the projector. Otherwise, it could fall or topple causing
an accident and injury.
When installing the projector in a high position, take measures to prevent falling
by using wires to ensure safety in an emergency, such as an earthquake, and to
prevent accidents. If it is not installed correctly, it could fall causing an accident
and injury.
Do not install in locations where salt damage could occur, or in locations subject
to corrosive gas such as sulphuric gas from hot springs. Otherwise, corrosion
could cause the projector to fall. It could also cause the projector to malfunction.
Attention
If you are using the projector at altitudes above 1,500 m, set the High Altitude
Mode setting to On in the projector's Installation menu to ensure the projector's
internal temperature is regulated properly.
Try not to setup the projector in locations subject to high humidity and dust, or
in locations subject to smoke from fires or tobacco smoke.
