Installation summary
Installation of the CS90 is a demanding task that requires careful preparations, a number of specific procedures, wiring and required system settings.
Context
An overall installation procedure is provided. This procedure does not describe any detailed tasks. Refer to the relevant tasks in this manual.
Note
In order to obtain maximum safety and CS90 performance, it is very important that the installation procedures in this manual are complied to. You must do the tasks in the order they are described. The vessel owner must make sure that the installation shipyard holds the applicable competence to perform the installation, and that the applicable maritime authorities are available to verify and certify the installation.
The size, location and design of the sonar room must fulfil all the requirements to the vessel’s watertight integrity. In the event of a major leak, it must be possible to close all watertight hatches and/or doors to the room to maintain vessel stability and safety. The physical size of the sonar room must be limited, so that in the event of a major leak, the flooding of the room will not induce instability, or cause the vessel to capsize or sink.
The installation shipyard must provide all necessary design and installation drawings, as well as the relevant work standards and mounting procedures. If required, all documents provided by the shipyard for the physical installation of the CS90 must be approved by the vessel’s national registry and corresponding maritime authority and/or classification society. Such approval must be obtained before the installation can begin. The shipowner and shipyard doing the installation are responsible for obtaining and paying for such approval.
Procedure
1 Based on the vessel drawings and best practice, determine where the hull unit shall be located.
Necessary considerations must be taken to avoid acoustic and electric disturbances.
Note
The information in this document must be regarded as general guidelines and recommendations only. The installation shipyard must design and manufacture installation hardware to fit the transducer to each individual vessel. Whenever required, the installation shipyard must also have the transducer installation approved by the applicable maritime authorities.
The CS90 Fish Finding Sonar can be provided with one of the following hull units.The same transducer is used on all hull unit types. Due to the different flange diameters, different installation trunks are used.

2 Prepare the sonar room to meet the installation requirements.
3 Install the gate valve.
These items are only installed if the optional gate valve is used.
Note
The mounting flange will penetrate the hull. For this reason, correct installation of the mounting flange and the gate valve is crucial for the vessel safety.
a Install the mounting flange.
b Place the gate valve on top of the mounting flange.
c Mount the transducer dock on top of the gate valve.
d If relevant, install the Hydraulic Power Pack and the Gate Valve Control Unit.
4 Mount the installation trunk.
The installation trunk is not used when a gate valve is mounted.
Note
The installation trunk will penetrate the hull. For this reason, mounting the installation trunk correctly is a crucial part of the installation.
5 Mount the Hull Unit on top of the installation trunk or the transducer dock.
6 Install the CS90 system units.
Note that some CS90 system units may be commercial. Unless ordered specifically these are not included in the delivery, and must be purchased locally.
7 Install the cables between the CS90 system units.
This is described in the Cable layout and interconnections chapter. Observe the relevant cable plan, procedures, as well as the general requirements for cabling.
8 Install the cables between the CS90 and the relevant peripheral devices.
This is described in the Cable layout and interconnections chapter. Observe the relevant cable plan, procedures, as well as the general requirements for cabling. For more information, refer to the end-user documentation provided by the manufacturer.
9 Turn on the CS90 for the first time, and set it to work.
Note
In order to turn on the CS90 in a safe and correct manner, the relevant procedures must be complied to!
10 Do a complete CS90 system test.
The tests are described in Setting to work chapter in this manual. They are also provided in the Harbour Acceptance Test and the Sea Acceptance Test documents.
