Clearance for Installing the Projector
• When installing the projector, keep sufficient space around it, as described below. If not, the hot
exhaust emitted from the projector may be taken back in.
Also, make sure no wind from an air-conditioner hits the projector.
The projector’s heat control system may detect an abnormality (temperature error) and automati-
cally shut off the power.

NOTE:
• In the above figure, it is assumed that there is sufficient space above the projector.
• For the portrait projection, each required clearance between the floor and the intake or the exhaust vent is same with the
clearance on the upper illustration. See page
for an installation example on portrait projection.
• When using multiple projectors together for multi-screen projection, provide sufficient space
around the projectors for air intake and exhaust. When the intake and exhaust vents are obstructed,
the temperature inside the projector will rise and this may result in a malfunction.
Precautions for Ceiling Installation
Do not install the projector in the following places. Attached substances such as oil, chemicals and
moisture may cause deformation or cracks of the cabinet, corrosion of the metal parts, or malfunction.
• Outdoors and places with humid or dust
• Places exposed to oil smoke or steam
• Places where corrosive gases are generated
