Notes on projector placement and operation
The projector uses a high-wattage lamp that becomes very hot during operation. Please observe the
following precautions.
1. Never place objects on top of the projector while it is operating.
2. Make sure there is an unobstructed space of 500 mm (1 feet 8 inches) or more around the projec-
tor’s exhaust openings.
3. Do not stack projector units directly on top of one another. If two units must be stacked for back-
up use in ordinary projection, use a method as shown below and provide ample space between the
units to ensure that exhaust heat does not accumulate near the intake opening or around the units.
Dual stacked projection is not recommended.
4. Make sure that nothing blocks the projector’s air intake and exhaust openings. Also, install the pro-
jector so that cool or hot air from other air conditioning equipment does not flow directly toward the
projector’s air intake or exhaust openings.
5. Do not install the projector in an enclosed space. If it is necessary to install it in an enclosed
space, add a separate ventilation system. If ventilation is insufficient, hot air will accumulate at the
intake opening. This may cause the projector’s protective circuit to interrupt projector operation.
6. If the projector is installed in an enclosed space, ensure that the temperature of the air surrounding
the projector is between 0°C and 40°C (32°F and 104°F). Also make sure that the projector’s intake
and exhaust openings are not blocked. Even though the air surrounding the projector is 40°C
(104°F) or less, if hot exhaust air accumulates inside the space, it may cause the projector’s protec-
tive circuit to interrupt projector operation. Pay particular attention to the surrounding temperature
conditions when planning the installation.
7. If the projector is not to be set on the floor using adjuster legs, install it by using the five ceiling-
mount screw holes (screw diameter: M6, length of each screw hole in the projector: 30 mm (1-3/16
inches)). Provide a space of 5 mm (3/16 inches) or more between the projector and the mounting
surface by inserting metal spacers.
