Screwed-To-Hull-Fitting With Valve Type 48.1.Rvb With 48.1.Rvb16 Sensor Or 65.1.Rvb With 65.2.Rvb.20 Sensor; Rvb.20 Sensor - BEN Marine ANTHEA Notice D'utilisation Et D'installation

For wooden hulls, hull thickness (including the reinforcement) must be less than the total
thickness the hull-fitting can tolerate. AMESYS/BEN Marine has developed systems for
different thicknesses of hulls. Contact an AMESYS/BEN Marine agent for further
information.
Anti-fouling paint must not be removed by abrasion. In certain cases, it is neither possible nor
recommended to put the sensor immediately in its working position. In this case, it is
necessary to prevent sensor (and connected-cable) damage until it is put in its final position.
When installation is over, do not forget to clean the sensor.

SENSOR OR 65.1.RVB WITH 65.2.RVB.20 SENSOR
(Drawing n° D0342)
Steel hulls may be too thin and require suitable reinforcement : minimum total thickness must
be 25 mm.
Check that actual thickness of the hull (including the reinforcement) is less than the tolerated
thickness.
Note: Reinforcement is always recommended on any type of hull.
1. Remove the sensor from the hull-fitting and from piece (16). Remove the 0-rings.
2. Drill a 64.5 mm diameter hole in the hull for 48 sensors or 93 mm diameter hole for 65
sensors. Remember to flatten external surface in order to get a perfect bearing of piece (1).
For plastic hull, take into account the instruction § "General rules for sensor installation".
Do an external chamfer (about 5 mm - 45°) for easy mounting and proper positioning of
piece (1).
Safety of the vessel depends from Installation.
3. Position hull casing (1) and use self polymerizing mastic for tightness (rubber, silicone
rilsan for example). Mastic layer must be thin. Let is harden to a pasty consistency.
4. Screw casing nut (2) on hull casing, and torque it with hammer or caulking tool. To avoid
the hull casing from unscrewing, block it with a wedge.
