Things To Note When Installing Projectors - NEC PH1202HL User Manual

Things to note when installing projectors

• Leave 60 cm/23.6" or over space between the projectors when projectors are installed side by side, so that the
intake vents of the projectors are not obstructed. In addition, leave a space of at least 30 cm/11.8" between the
intake vent and the wall and at least 70 cm/27.6" between the exhaust vent and the wall. When the air intake and
discharge outlet are obstructed, the temperature inside the projector will rise and this may result in a malfunction.
• Do not directly stack projector units.
WARNING
• Example of multiple projectors installed together
When using multiple projectors together for multi screen projection, be sure to set them up in a specialized projector
cabinet like the one that follows.

WARNING
Please request the dealer for special installation services such as when mounting the projector to the ceiling. Never
carry out the installation by yourself. The projector may fall down and result in injury. Please use a sturdy cabinet
that can withstand the weight of the projector for the installation. Please do not pile up the projectors directly on
top of one another.
NOTE:
• For the range of the projection distance, please refer to the Appendix "Throw distance and screen size". (→ page 156)
