Installation (continued)

Installing the attachment plate
Depending on whether it is installed on a concrete or wooden ceiling structure, there are two different
installation methods. Carry out by the appropriate installation method which is suited to each ceiling.
Attention
z
Make sure to use the ceiling mount bolts, hex nuts, flat washers, spring
washers, anchoring nuts or curled plugs for M10.
z
All nuts and bolts should be securely tightened, and sufficient measures such
as using two nuts or locking the bolts should be employed as necessary to
prevent any loosening.

1)
Drill four penetration holes in the ceiling beam for
the ceiling mount bolts.
z
Drill the penetration holes with same size as
the ceiling mount bolt mounting holes. (Refer to
page 6
for hole locations and dimensions.)
2) Securely fix the four ceiling mount bolts to the
ceiling beam.
z
Confirm that the location to retain the ceiling
mount bolts has enough strength to retain the
weight of the projector and the ceiling mount
bracket. If there is not enough strength, perform
sufficient reinforcement considering the safety
factor.
3)
Temporarily secure the attachment plate to the
ceiling mount bolts.
(It will be permanently secured after adjusting the
installation angle in horizontal directions on page 12
.)
z
The threaded end of ceiling mount bolt at
the attachment plate side should protrude by
approx. 5 mm (3/16") from the hex nut. Be sure
to use commercially available flat and spring
washers to install the attachment plate.
