Also take steps to ensurethat the hot air blown out from the air exhaust outlet will not be sucked into the air intake.• Install with clearances of at least 30 cm provided for the side panels to enable the air filter to beremoved and re-installed.• When operating the projector in an enclosure, ensure that the temperature of the surrounding airwithin the enclosure remains within the range 0 °C to 40 °C while the projector is running. Alsoensure that the air intake and exhaust vents are unobstructed. Even when the surrounding airtemperature is maintained below 40 °C, operation of the protection circuit could cause a shutdowndue to hot exhaust air being trapped inside the projector. When designing the enclosure, pleasegive due consideration to the thermal environment surrounding the projector (Figure 2).Attention
