Projector Preparation
CAUTION:
THE PROJECTOR IS FRAGILE; HANDLE WITH CARE AT ALL TIMES.
NOTE
:
Review the projector manufacturers operation manual and refer to the ceiling mount installation
section. Important information concerning the installation dimensions (i.e. distance from the
screen to the lens of the projector, top of the lens placement to the top screen, etc.) will be found
in this section. Adherence to these instructions will simplify the installation and enhance the
quality of the final screen image.
1.
Carefully invert the projector and place it on a smooth, flat surface.
2.
Identify the number of mounting points and screw thread size. Most projectors have either three of
four mounting points and are M4, M5 or M6 in thread size (Figure 1).

3.
Separate the upper assembly from the projector mounting bracket by slightly loosening the two
tension knurl knobs to create free play between the bracket tri-lock assembly and the upper section
tri-lock assembly points (Figure 2A and Figure 2B).
4.
Loosen the security screw knurl knob far enough to allow the two parts to be rotated 180° apart and
separate (Figure 2C).
