1. HOW TO INSTALL THE SYSTEM
2. Apply lithium grease to the O-ring and O-ring groove. Place the O-ring in its
groove on the tank flange.
3. Orient the hull unit so that the bow mark (inscribed) on its flange points toward the
ship's bow. Note that heading adjustment is required if the bow mark is not facing
the ship's bow. (See section 3.4.)
4. Confirm the points as listed below, then place the hull unit on the tank.
• Clean the flange platform.
• Wipe the under-face of the hull unit with clean waste cloths.
• Keep the O-ring in its groove.
5. Apply a slight amount of lithium grease to the threads of the hex bolts and stud
bolts to prevent scorching, then secure the hull unit to the retraction tank, referring
to the following figure.
