EXHAUST VENTS
AIR INTAKE VENT
(Bottom)
The projector uses a lamp which generates
significant heat. The cooling fans and air vents are
provided to dissipate the heat by drawing air into the
housing and the filter is located in the intake vent to
prevent dust from getting inside of the projector.
In order to care for the projector appropriately,
regular cleaning is required. Remove any dirt or dust
that has accumulated on the projector.
If the projector reaches a time set in the timer
setting, the icon as shown in Fig. 1 appears on the
screen and WARNING FILTER indicator lights up (see
below), indicating that cleaning or replacing the filter
is necessary.
If the projector detects that the filter is clogged, the
icon as shown in Fig. 2 appears on the screen and
WARNING FILTER indicator lights up (see below).
Stop using the projector immediately and replace the
electrostatic honeycomb filter and the electrostatic
pleated filter.
Blocking the air vents and leaving the projector
uncleaned for a long time may not only damage the
projector and may require costly repairs but may also
cause accidents or fire.
For maintenance of the filter, refer to “Filter counter”
on page 68 and “Maintenance and Care” on pages
72-74.
Damages to the projector caused by using an
uncleaned filter or improper maintenance will
void the warranty on the projector.
CAUTION
Hot air is exhausted from the exhaust vents. When
using or installing the projector, the following
precautions should be taken.
– Do not put any flammable object or spray can near
the projector, hot air is exhausted from the air vents.
– Keep the exhaust vents at least 3’ (1 m) away from
any objects.
– Do not touch peripheral parts of the exhaust vents,
especially screws and metallic parts. These areas will
become hot while the projector is being used.
– Do not put anything on the cabinet. Objects put on
the cabinet will not only get damaged but also may
cause fire hazard by heat.
– Do not cover vents with papers or other materials.
– Make sure that there are no objects under the
projector. An object under the projector may prevent
the projector from taking cooling air through bottom
vent.
– When detaching the adjustable feet, always keep at
least 50 mm between the bottom of the projector
and installation surface.
Cooling fans are provided to cool down the projector.
The fans’ running speed is changed according to the
temperature inside the projector.
