Caution to the installation for the Tilt-free projection
Do not install the projector in the state of facing up/down or inclined directly on a floor and a table. If the projector
falls down, It may cause of malfunction, damage and human injury. If the intake vents are obstructed, the projector
inside temperature will increase and it may cause of malfunction and fire.
Make sure to produce the support metal for the projector as the ceiling mount metal. Please ask the service
company about the support metal production. (for a fee)
In case you need to install the projector in tilted angle, please install the projector by support metals that have
enough durability to support the projector for a long time.
Design and manufacturing conditions for a stand and a ceiling mount metal of the projector
Please hire an installation service provider (for a fee) to design and manufacture customized stand and ceiling mount
metal. Please ensure that the design complies with the following conditions:
There is one intake vent on either side and one exhaust vent at the rear. These should remain unobstructed. Also,
secure enough space for easy filter cover removal for filter cleaning.
Remove the level adjusters or the projector handles in case these hit against the stand. For removing the level
adjuster, rotate the level adjuster itself, and for removing the handle, remove the handle fastening screws.
Fix the stand onto the ceiling mount screw holes (6 positions) on the projector bottom face.
Dimensions of screw hole: for M6 screw Maximum depth 10 mm (Calculate the bolt length depending on the stand
design)
Horizontal adjustment mechanism (for example, bolts and nuts in 4 places)
Make sure to design the stand not falling over easily.
Make sure if the projector is fixed on the surface that has enough durability to stand the whole projector weight
(the projector weight 68kg plus the lens weight 3kg, i.e., 71kg in total) for a long time.
