It is important that the sonar room is kept clean and dry. The system units must not be exposed to excessive temperatures, dust, moisture or humidity. Such conditions can cause corrosive attacks and subsequent failures to the electronic circuitry.
Make sure that installation or maintenance of other equipment in the sonar room does not affect the SU90 system units. The use of heavy tools in the sonar room must be avoided. This includes welding equipment, saws, hammers or similar hand or electrical equipment. Such tools can cause serious electrical and/or mechanical damage. If heavy maintenance or construction work in the sonar room cannot be avoided, all SU90 system units must be well protected against dust, dirt and damage. Kongsberg Maritime AS takes no responsibility for any failures or damage to SU90 system units that are caused by installation, maintenance or construction work in the sonar room.
Visit the sonar room at regular intervals to check for dust, high temperature and humidity. Take the necessary actions if the environmental conditions are poor. We recommended that you keep the ambient temperature between +5 and +40°C, and the relative humidity less than 80%. The Mean Time Between Failure (MTBF) will increase if these limits are exceeded.
Observe the environmental specifications related to each unit.
