Before Installation
■ When Using Mounted on the Ceiling
When the projector is used mounted on
the ceiling or installed in a high
location, it is necessary to periodically
clean the air intake and exhaust vents,
and the area around the air filter. Dust
that accumulates in intake or exhaust
vents may impair ventilation, raising the
temperature inside and posing a risk of
damage or fire. Use a vacuum cleaner
or similar means to remove dust from
the intake vent and exhaust vent.
■ Install Facing in the Correct Direction
• Projection is possible upward, downward, or in a variety of
directions, but do not block the air intake and exhaust vents. In
particular, always ensure a minimum clearance of 2 cm (0.8")
from the air intake vent on the bottom of the projector.
• There are no options for installing the projector other than the
ceiling attachment.
