1. HOW TO INSTALL THE SYSTEM
Note 1: After you install the hull unit,
make sure you install anti-vibration stays.
(See "How to install the stays (anti-vibra-
tion and anti-shock
measures)" on page 1-6.)
Note 2: Prepare a secure and firm safety
fence for the hull unit, to prevent acciden-
tal injury from the moving hull unit. The
safety fence should be easily removable
for maintenance and allow room for the
connected cables to swing freely with
pitch, roll and heave. The raise/lower con-
trol unit and emergency buttom should be
installed and operatable from outside the
safety fence.
1.1.2 How to shorten the retraction tank
The following table provides cutting guidelines for shortening the tank. Refer also to
the retraction tank installation drawing at the back of this manual.
Note 1: The default length for the retraction
tank is 1300 mm. By removing only 88 mm
from the retraction tank, you can eliminate the
need for limit switch adjustment.
Note 2: For both 1200 mm and 1600 mm trav-
el hull units, the transducer will not fully re-
tract unless the tank is shortened by more
than 90 mm.
