INSTALLATION OF CSH-8L ON
RETRACTION TANK OF CH/FH
SERIES SONAR, OR 1800/3500 MM
TANK
When retrofitting the CH/FH series with the CSH-8L, it is not necessary to change the
retraction tank. However, the hull unit must be chosen according to retraction tank length.
Refer to the table below to choose hull unit. This must also be done with the 1800 mm or
3500 mm retraction tank.

CSH-8040-85-Nx40
Transducer cable: 6600 mm, Main shaft: 4065 mm
Note: The hull unit CSH-8041 (400 mm transducer travel) cannot be used.
Installation when retraction tank is more than 750 mm
long
1. Calculate the necessary length of the main shaft.
•
Main shaft length = Tank 565 mm (see page AP-5).
•
If there is a sufficient space above the hull unit, it is not necessary to cut the main shaft;
the main shaft is installed with its top portion protruded beyond the top of the hull unit.
•
If the cut length of the main shaft is less than 50 mm, use it without cutting the shaft.
Waterproofing attachment is not necessary. Note, however, that protrusion length of the
transducer is reduced.
