WARNING
To the customer
■ Do not attempt to install the projector yourself. Have your dealer or service center handle all
installation work. Note that Hitachi will accept no liability whatsoever for accidents or injuries
resulting from an incorrect installation or improper use.
■ Make sure that the projector is installed high enough so that there is no risk of people bumping their
heads. If a sufficiently high installation cannot be made, be sure to take the necessary precautions
when the projector is used.
■ Do not hang on the LCD projector or the arm after installation as this could cause the LCD projector
to fall down or bend the arm resulting in injury or damage.
■ Do not install the projector in a location exposed to high humidity, dust or tobacco smoke or in a
location exposed to smoke or steam.
■ Do not install the projector in a location exposed to vibrations.
■ After you have finished installation, keep this manual and accessories in a safe place for future
reference.
■ Small parts such as screw caps and adjusting knobs could be swallowed by children and pets
and should be kept out of their reach. If your child swallows any small parts, consult a doctor
immediately.
To service personnel
■ Perform all installation work correctly according to this manual. Make sure that all specified screws
and brackets are used in the installation.
■ Considerable care is required in planning and performing the installation so that it will support the
weight of the LCD projector and wall mount unit.
■ Never attempt to modify the wall mount unit. (We will not guarantee the strength of a unit that has
been modified.)
■ Make sure that all screws are tightened to the proper torque after installation and adjustments. There
must be no loose or over tightened screws.
■ Do not use adhesives, lubricants, lubricating oils or other chemicals designed to prevent loosening
of fasteners on screws and bolts used to secure the projector ceiling mount. The use of such
materials could cause the mount to fail and the projector to fall resulting in damage or injury.
■ Route electric cables as prescribed and take care not to damage them in the installation work.
■ Be sure to read this manual and the User’s Manual of the LCD projector prior to installation to
ensure that all safety instructions are observed and the projector is correctly installed.
■ Be sure to turn off the LCD projector and disconnect the power plug from the wall outlet before
starting installation work.
Routine Inspections
Like the projector, the wall mount unit should be inspected once a year.
1. Check that the screws in the wall mount unit and adjusted parts are not loose.
2. Check that the wall mount unit, adjusted parts and the set are not scarred or damaged.
