5.
Screw the four thru-bolts ref (3) into the nut threaded holes (piece ref. 2) and butt them
firmly against the hull plating in order to prevent future unscrewing of the nut. Safety is
increased if a blind hole of a few mm depth is drilled facing the bolt. For plastic hulls, it is
recommended to glue the nut to the hull with polymerizing fibered polyester.
6.
Clean and grease 0-rings (11) an (12). Put them in place. Install the gate valve and properly
adjust it (with regard to thru-bolt ref.3).
7.
Put the upper 0-ring (6) in place in its landing, suitably greased. Install the upper flange
(5).
8.
Screw the safety nuts (19) on thru-bolt (3) forcing moderately and equally.
9.
Put 0-ring (13) in place.
10.Fill the inner part of outer bush (16) with self polymerizing silicone rubber such as
"syntofer". Remember to fill only the part indicated on D0342 drawing.
11.Introduce isolating part ref (16) with force. Make sure that it is properly positioned. Check
that nothing protrudes and try to introduce the sensor from the outside. Let the mastic
harden.
12.Grease flat seal (7) and put it in place.
13.Carefully lubricate the sensor and introduce it in its proper location. Take care to not
grease the electrode.
14.Use grease supplied with spares. When properly positioned, the sensitive surface of the
sensor protrudes at least 1 mm from external bush, and the red mark on the sensor head is
directed towards the bow.
15.Fix sensor flange (8) with screws (9) and washers (20) ; put circlip 15. Connect the link
(10). Check link length : it must be long enough to allow closing of the valve and short
enough to prevent sensor from escaping and passing over 0-ring (6).
When using anti-fouling paint,
DOT NOT PAINT THE ELECTRODES - DO NOT GREASE THE
LECTRODES
Note: to avoid sensor damage, it is recommended to put sensor in place just before
departure, or while at sea (in this case, do not forget to close the valve).
