Important Safeguards
These safety instructions are to ensure the long life of your projector and to prevent fire and shock. Please read them
carefully and heed all warnings.
Installation
• Do not place the projector in the following conditions:
- on an unstable cart, stand, or table.
- near water, baths, or damp rooms.
- in direct sunlight, near heaters, or heat radiating appliances.
- in a dusty, smoky or steamy environment.
- on a sheet of paper or cloth, rugs or carpets.
• If you wish to have the projector installed on the ceiling:
- Do not attempt to install the projector yourself.
- The projector must be installed by qualified technicians in order to ensure proper operation and reduce the risk of
bodily injury.
- In addition, the ceiling must be strong enough to support the projector and the installation must be in accordance
with any local building codes.
- Please consult your dealer for more information.
• For sales or service representatives:
- Use brackets that are strong enough to support the projector. (PJ WU6181N Series weighs about 8.4kg.(18.5lbs))
(Not including lens)
- The projector must be installed in a location that is sturdy enough to support the full weight of the projector and
brackets.
- Use only the screws (four M4~16 screws) provided with the projector to attach the brackets to the projector.
- Use all four of the projector’s screw holes to attach the brackets. The locations of the screw holes are shown in the
illustration below.( → page 242 ) Make sure that the screws are tightened firmly.
WARNING
• Do not cover the lens with the lens cap or equivalent while the projector is on. Doing so can lead to melting of the
cap due to the heat emitted from the light output.
• Do not place any objects, which are easily affected by heat, in front of the projector lens. Doing so could lead to
the object melting from the heat that is emitted from the light output.
Do not use the projector with it leaning to the left and right. This may result in a malfunction. However, portrait installation is
possible* (when a custom-designed stand is made). For portrait installation, install the projector with the intake vent at the bot-
tom and leave a space of at least 130 mm below the intake vent.
