t Air inlet (filter)
Air is taken in through the filter to cool the light-source
lamp. If the filter is blocked or if something that obstructs
the flow of air is placed around the projector, heat may
build up inside and could cause a fire. For required
space, 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 filter, or heat may build
up and could cause a fire.
• Clean the filter periodically. For details, refer to “Cleaning
and Replacing the Filter Cover” on page 63. Deposition of
dirt on the filter reduces the cooling effect, causing heat to
build up inside, which could cause a fire or malfunction.
y Opening for replacing the light-source lamp
For replacing the light-source lamp, refer to “Replacing
the Light-Source Lamp” on page 58.
