Things To Note When Installing Projectors - NEC PA622U User Manual

Things to note when installing projectors

• Leave sufficient space on the left and right of the projector so that the air intake and discharge outlets of the projector
are not obstructed. When the air intake and discharge outlet are obstructed, the temperature inside the projector
will rise and this may result in a malfunction.
• Please do not pile up the projectors directly on top of one another when installing them. When the projectors are
piled up on top of one another, they may fall down, resulting in damage and failure.
• Installation example when using two projectors
The following installation is recommended when combining the installation of two projectors for multi-screen projec-
tion. Please leave a space of at least 10 cm between the air intake/discharge outlet and the wall.

WARNING
Please request the retail store 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 158)
