Air intake area (filter)
Air is taken in through this area to cool the light-source
lamp. If this area is blocked or if something that obstructs
taking in or exhausting air is placed around the projector,
heat may build up inside and could cause a fire. For details,
refer to “Precautions for Installation” on page 15.
CAUTIONS
• Be careful as paper, cloth or soft cushion could be drawn in
if placed nearby. Do not block the intake area, or heat may
build up and could cause a fire.
• Clean the filter periodically. For details, refer to “Cleaning
and Replacing the Filter” on page 64.
Deposition of dirt on the filter works to reduce the cooling
effect, causing heat to build up inside, which could cause a
fire or malfunction.

Position selecting screw for ceiling mounting
When using the projector in an upside-down, ceiling-
mounted position (inverted top-to-bottom and right-to-left),
the “position selecting screw for ceiling mounting” must be
turned to switch to ceiling mounting.
This will correct variance in color images (shading), which
otherwise would occur in ceiling mounting.
For more information, refer to “Setting the position
selecting screw for ceiling mounting” on page 18.
CAUTIONS
• To ceiling-mount and adjust the projector, special expertise
and technique are necessary. Be sure to ask your dealer or
a specialist to perform this work.
