Insert the echo sounder into the hull sleeve and align the hole in
the upper sounder section with the holes in the sleeve.
4.
Secure the sounder by inserting the retainer pin through the holes.
5.
Lock the retainer pin by installing the rings at both pin ends.
Tie the control rope of the blind plug to one of the retainer pin rings.
You will need the blind plug to remove the sounder. In this case the blind
plug must be secured in the same way as the sounder.
Please note that a considerable quantity of water can enter
the ship while the sounder is being removed.
Never remove the sounder with the ship in the water. Never
pull on the cable to remove the echo sounder. Insert the
blind plug after removal of the echo sounder.
The sounder can be covered with a thin coat of antifouling paint. This
coat must be free of air bubbles, which would impair the echo sounder
function.
