Actions to be taken whenever required
The hull unit was lubricated as a part of the production process. It was thus provided fully lubricated when delivered to the vessel. Additional lubrication of the hull unit must only take place when required.
Note
A hull unit may be provided as an option. It allows you to lower and hoist the transducer. All information and tasks related to the hull unit may be disregarded and omitted if the SN90 system is installed without this unit.
