Please observe thefollowing precautions.1. Never place objects on top of the projector while it is operating.2. Make sure there is the unobstructed space as shown below or more around the projector’s exhaustopenings. In addition to this space, also ensure that there is a sufficient work space for removingand installing the lamp, air filter and other parts.3. 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 theprojector’s air intake or exhaust openings.4. Do not install the projector in an enclosed space. If it is necessary to install it in an enclosedspace, add a separate ventilation system. If ventilation is insufficient, hot air will accumulate at theintake opening. This may cause the projector’s protective circuit to interrupt projector operation.Direction of air intake and exhaust500 mm (19-11/16˝)or more500 mm (19-11/16˝)or more1000 mm (39-3/8˝)or moreIntakeExhaustOperating the projector continuously1.
