About installation
Important points concerning the installation
This unit is a precision device. Therefore, please refrain
from installation or use in the following locations.
Otherwise, it may cause
fi
re or malfunction.
•
Dust, wet and humid locations.
•
Sooty or cigarette smoke
fi
lled locations.
•
On top of a carpet or bedding, or other soft surfaces.
•
Locations with high temperatures - as located in direct
sunlight.
•
Locations with high or low temperatures.
Permissible operating temperature range: +5
º
to +35
º
.
Relative humidity range permissible for operating: 20%
~ 80% (non-condensing) .
Storage temperature tolerance: -10
º
to +60
º.
•
If the installation of the unit is done in a room with soot
and/or smoke over a longer period, even small amounts
of these substances will affect the device.This unit
cools its optical components, which produce a great
amount of heat, by sucking in air. If the optical circuits
get dirty, this might lead to malfunctions, like the video
images becoming darker or a deterioration of the color
development. Dirt sticking to the optical components
cannot be removed.
For better heat dissipation, please keep a minimum
distance between this unit and its surroundings as shown
in the following illustration.
Moreover, please open the front of the unit. If there are
any objects in front of the exhaust port, the hot air will
fl
ow back to the unit and heat it. The hot air
fl
owing out of
the unit might cause shadows on the screen (heat haze
phenomenon).
Moreover, when it is enclosed in a space as shown in the
following illustration, please make sure that the enclosed
interior has the same temperature as the outside. High
temperatures might lead to failure of the unit.
This unit uses a projection lamp, which will get hot when
in use. Please refrain from projecting in the following
circumstances.
Otherwise, it might cause
fi
re or malfunction.
•
Projection while lying on its side.
Please avoid projection if the installation of the unit is
done at an excessive angle of more than
±
30
°
. It may
cause harm to the life of the lamp and color shading.
•
Please avoid projection at a location where the air vents
or exhaust ports might get blocked.
Please choose a non-uniform cloth material for the screen.
If you choose something uniform, like something with a
checkered pattern, there might be interference with the
pixel array of the D-ILA components. One way to reduce
the interference pattern is to change the size of the screen,
so that it will not be so noticeable.
