The Sonar Head Unit is mounted to the survey vessel by attaching the mounting
flange at the top of Sonar Head Unit to a standard 6-inch pipe flange or other
mounting surface. A bolt pattern is provided on the mounting flange as shown in
Figure 3-1. For a typical, pole mount type over-the-side installation, this design is
well suited for attaching to the base of a pipe.
CAUTION
Always avoid putting excessive silicon grease on the Subcon
male pins. Apply a light coat of grease, and never put grease into the female
connectors.
NOTE
When installing the Sonar Head Unit, refer to Drawing 14605080 in
APPENDIX B: “Drawings.” for the outline dimensions of the Sonar Head
Unit.

NOTE
When attaching the Sonar Head Unit to the mounting surface, it is
important to ensure that the assembly is mounted correctly in the fore/aft
direction. The end of the Sonar Head Unit that faces the bow is labeled
FWD on the neck of the mounting flange as shown in Figure 3-2. An arrow label is
also included.
