HAS-K252

Installation of this product requires special technical skills. Ask your dealer or service center (for details, see the
User’s Manual supplied with the LCD projector) to handle the installation work.

Be sure to observe the following instructions when installing an LCD projector.

1. 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.

LCD projector Approx. 3.8 kg

Wall mount unit (HAS-K252) Approx. 4.8 kg

2. If the temperature inside the LCD projector gets too high, the temperature sensor will activate and turn off the
projector to prevent damage. Do the following to avoid an abnormally high temperature.

(1) Select a location where the ambient temperature is in the range of 0 to 40°C.

(2) Periodically clean the projector’s air intake lter. For details on how often and how to clean the lter, see the

LCD Projector User’s Manual.

(3) In a dusty location, the lter will need more frequent cleaning than in (2) above so install the projector in a

location where cleaning is easy.

(4) Leave 30 cm or more space on the sides of the LCD projector to allow the free ow of air from the exhaust and

leave 10 mm or more space at the back of the projector to enable air to enter via the air intake.

(5) Do not install the projector in a location exposed to sudden temperature changes, for example near air

conditioners, or where the temperature rises above 40°C.

3. Do not install the projector in a smoke-lled or extremely dusty environment as the tar in cigarette smoke will

settle on the optics and lower performance.

4. Do not install the projector in a location where the remote control sensor will be exposed to direct sunlight, other

strong light sources or inverter uorescent lamp light at close range to prevent remote control malfunction.

● The wall mount unit must be secured using at least eight M10 anchor bolts. The

bracket has 16 oval 11 × 33 mm (0.43 × 1.3 inch) mounting holes. Use anchor bolts of
a length that suits the strength and thickness of the wall so that the pullout strength of

each bolt meets or exceeds 2,000 N. If required, increase the number of anchor bolts.

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 sufciently 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 nished 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 specied screws

and brackets are used in the installation.

■ Considerable care is required in planning and per forming 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 modied.)

■ 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.
