Considerations for projector
installation
Please read the following carefully before in-
stalling this unit.
Installation Environment
This unit is a precision device. Do not install it
in the following places. Doing so may cause
fire or malfunction of the unit.
• Where there is water, humidity or dust
• Where the unit may be subjected to oily or ciga-
rette smoke
• On a soft surface such as carpet or cushion
• Where the unit may be subjected to high tem-
perature due to direct sunlight
• When temperature is high or low.
Allowable operation temperature range: +5 to
+35 degrees Celsius.
Allowable relative humidity range: 20 % to 80
% (no condensation)
Allowable storage temperature range: -10 to
+60 degrees Celsius
• Any room in which there is cigarette smoke or
grease.
Even where smoke and grease levels are mini-
mal, prolonged exposure will affect this unit.
This unit produces significant amounts of
heat, and the optical components are cooled
by taking in a large amount of air. The optical
path may be soiled by grease/dirt, thus causing
images to become dark or colour projection to
deteriorate. Where soiling of the optical compo-
nents occurs, total removal of grease/dirt may
not be possible.
Operating Precautions
This unit uses a light source that reaches high
temperatures during projection.
Do not allow projection under the follow-
ing conditions, as doing so may cause fire
or failure of the unit:
• Projection with the unit laid on its sides
• Projection with the unit installed in an unrea-
sonable angle
Avoid using this unit at an angle of more than
5 degrees horizontally and 25 degrees vertically.
Doing so may cause unevenness in the colour
and/or shorten the lamp life.
• Projection in a location that blocks the air inlets
or exhaust vents
• Projection in a place exposed to air blasts from
an air conditioner
• Projection without removing the lens cap
Mounting the projector
The projector can be operated in a free-stand-
ing position using the feet supplied. To mount
the projector, remove the 4 feet and make use
of the 4 screw holes (M8 nuts) on the under-
side of the projector. Allow sufficient space
around the air inlets to avoid blocking them.
Precautions for Ceiling-mount
• To ceiling-mount this unit, special expertise and
techniques are necessary. Be sure to ask your
dealer (or a specialist) to perform mounting (to
ceilings, etc.).
• Do not mount in places that may be subjected
to vibration and shock.
• The depth of the threaded holes is 30 mm. Use
screws shorter than 30 mm but longer than 19
mm. Longer screws may damage internal parts
of the projector and cause malfunction.
• Safety of the installation location should be
considered in case this unit, or a part of it, falls.
Note that if the light-source lamp is broken,
glass shards from the filter mesh may spread
outside the projector.
Minimum Space Required
Do not use a cover which may enclose this unit
or block the air inlets/exhaust vents. Allow suf-
ficient space around this unit. When this unit is
enclosed in a space of dimensions as indicated
on the left, use an air-conditioner so that inter-
nal and external temperatures are the same.
