1-1. Clearance for Installing the Projector (English)

Allow ample clearance between the projector and its surroundings as shown below.
The high temperature exhaust coming out of the device may be sucked into the device again.
Avoid installing the projector in a place where air movement from the HVAC is directed at the projector.
Heated air from the HVAC can be taken in by the projector's intake vent. If this happens, the temperature inside the
projector will rise too high causing the over-temperature protector to automatically turn off the projectors power.
