Procedure
1 Determine the physical location of the transducer.
The decision must be based on:
• The vessel drawings
• The shape and properties of the hull
Make sure that all possible considerations are made to reduce noise.
• Transducer installation principles, page 51
• Where to install the transducer, page 70
2 Based on the shape of the transducer housing, and the mounting devices available,
determine the installation method.
3 Design, manufacture and mount the necessary fairing, installation blister, keel box
and/or tank that is required to mount the transducer.
4 Install the bushing.
5 Design, manufacture and mount the steel conduit for the transducer cable.
6 Unpack the transducer from its transport crate.
7 Position the transducer under the mounting location.
8 Pull the transducer cable up through the steel conduit.
9 Tighten the packing nipple on the cable gland properly to avoid leaks.
10 Mount the transducer.
11 Seal the top of the steel conduit to prevent water leaks.
12 Connect the transducer cable to the transceiver.
13 If your vessel will operate in waters with a lot of marine growth, consider applying
a thin layer of anti-fouling paint to the transducer face.
