Installing the Projector
Precautions for Installation
CAUTIONS
• Since the projector weighs approx. 70 kg (154 lbs.), be sure to use four or more people when lifting
or moving it; otherwise, the projector could possibly drop, causing personal injury and/or damage
to the projector.
• Do not install the projector in the following places :
• There is much water, humidity or dust.
• The projector may be subjected to oil smoke or cigarette smoke.
• On a soft surface such as a carpet or cushion.
• The projector may be subjected to direct sunlight.
• Temperature is high or humidity is low.
Allowable operation temperature range: + 5°C to + 40°C (41°F to 104°F)
Allowable relative humidity range:
90% or less (no condensation)
Allowable storage temperature range:
–5°C to +60°C (23°F to 140°F)
When installing the projector, observe the followings:
• Do not use the projector placed on its side.
Avoid using the projector placed on its side. This could cause a malfunction.
• Use the projector within the installed angle.
Avoid using the projector inclined ±5° or more right-to-left or left-to-right. This could cause color variation or harm the lamp
life.
• Do not block the exhaust vents.
Do not use a cover which encloses the projector air-tight or blocks the exhaust vents. Allow sufficient space around the
projector. When the projector is enclosed in a space of the following dimensions, use an air conditioner so the temperature
inside becomes equal to the outside temperature.

Precautions for Installation (Cont.)
Observe the following points when installing the projector by hanging it from the ceiling
• To prevent falling or overturning, it is recommended that the projector be fixed to its stand with bolts.
• When mounting the projector to the ceiling, first install a special shelf and then set the projector on it securely. For safety
and maintenance purposes, a suitable facility is necessary to easily lift and lower the projector from the shelf for mainte-
nance access.
Relationship relative to Glass Surface
Light energy decreases as it passes a glass. So, no more than one glass should be used in the projecting room.
Avoid using panes of glass as much as possible.
Pay attention to the angle of the glass and the installed angle of the projector so that the light emitted from the
projector does not come back into the lens after reflection.

Avoid the light reflected from the glass
entering the surface of the projector lens.
