WARNING
1. Do not cover the lens with the supplied lens cap or
equivalent while the projector is on. Doing so can lead
to distorting or melting of the cap and burning your
hands due to the heat emitted from the light output.
2. 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.
When using the projector tilted in the forward or backward
direction, use it in the range of (+10° to -15°) from horizontal.
If you tilt it outside of this range or tilt it to the left or right, it
may become damaged.
If the projector is tilted outside of this range when used tilted
in the forward or backward direction, "TiltDegreeOver" is dis-
played on the LCD screen. If this message appears, change
the installation of the projector so that the angle is within the
given range from horizontal.

Power Supply
1. The projector is so designed that it operates with the
power supply voltage described below.
• Projector
AC200-240V 10.7A(MAX) 50/60Hz Single-phase
• Chiller unit
AC200-240V 9.2A 50Hz Single-phase
AC220-240V 10.3A 60Hz Single-phase
Ensure that your power supply fits this requirement
before attempting to use your projector.
2. The power cable is not included with the projector. Ask
your dealer for the power cable to select and purchase.
Use a power cable that meets the standards and power
supply voltage of the country where you are using the
projector.
Refer to "2-3. Selecting the Power Cable (Projector)
(English)" (page 51), "2-7. Connecting the Power Cable for
the Chiller Unit" (page 64), for details on connecting the
power cable.
3. Handle the power cable carefully. A damaged or frayed
power cable can cause electric shock or fire.
• Do not bend or tug the power cable excessively.
• Do not place the power cable under the projector, or
any heavy object.
• Do not cover the power cable with other soft materials
such as rugs.
• Do not heat the power cable.
• Do not change the arrangement of the installed power
cable.
4. If the projector will not be used for an extended period of
time, turn off the projector and chiller unit, and discon-
nect the power plug from the outlet.
5. Placing the power cable and the signal cable closely to
each other can cause beat noise. If this happens, keep
the two separated so that beat noise is not generated.
Beat noise is corruption of the picture often seen as a
rolling band moving through the image.
6. Do not touch the projector during a thunder storm. Doing
so can cause electrical shock or fire.
For UK only: In UK, a BS approved power cable with
moulded plug has a Black (five Amps) fuse installed for
use with this equipment. If a power cable is not supplied
with this equipment please contact your supplier.
CAUTION
The power cable stopper (shown in below) is supplied with
this projector.
To prevent the power cable from coming loose, make sure
that all the prongs of the power cable are fully inserted into
the AC IN terminal of the projector before using the power
cable stopper to fix the power cable. A loose contact of the
power cable may cause a fire or electric shock. For using
the power cable stopper, refer to the user's manual.
Fire and Shock Precautions
1. Ensure that there is sufficient ventilation and that vents
are unobstructed to prevent potentially dangerous con-
centrations of ozone and the build-up of heat inside your
projector. Allow at least 12 inches (30 cm) of space
between your projector and a wall. In particular, clear a
space of 27.6 inches (70 cm) or more in front of the air
outlet on the rear surface. Allow at least 19.8 inches (50
cm) of space between your chiller unit and a wall. (See
page 32)
