Chapter 2: Installation
• Choose a location that meets the mounting location requirements.
• Using the fixed base as a template, mark and drill the mounting holes as necessary for the mounting
surface.
Flush mounting the 3D:
1. Photocopy the section of the 3D that contains the four mounting holes for use as a template to plan
the mounting hole locations.
of the 3D.
Make sure the photocopy is scaled one to one with the mounting holes on the bottom
2. Mark the mounting hole centers on the mounting surface.
3. Place the 3D over the marks to ensure the planned hole centers align with the true hole centers
(adjusting as necessary).
4. Use a center punch to mark the hole centers.
5. Drill the mounting holes with a 9 mm bit appropriate for the surface.
6. Place the 3D over the mounting holes and insert the mounting screws through the bottom of the
mounting surface and into the 3D.
When installing the 3D, hand tighten only. Damage resulting from overtightening is
not covered by the warranty.
Pole Mount
Keep the following in mind when using a pole mount:
• Mounting hole is 1" thread, 0.9" depth
• Hand tighten until snug (do not overtighten) while ensuring correct orientation
• Use the set screws on the long sides of the base (see Figure 2-6) to secure the 3D in place (3/16"
Allen wrench not included)
Overtightening may damage the system. This is not covered under warranty.
Before pole mounting the 3D:
•
Decide if you need the roll measurement. If you need roll measurement, the 3D will need to be
installed perpendicular to the vessel axis. If it you do not need roll measurement, install the 3D
parallel with the vessel’s axis.
• Choose a location that meets the mounting location requirements.
