INSTALLING CSH-5L ON THE
RETRACTION TANK OF CH/FH
SERIES SONARS OR BY USING
1800/3500 MM TANK
When retrofitting the CH/FH series with the CSH-5L 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 bellow to choose hull unit. This must also be done with the 1800 mm or
3500 mm retraction tank.

Note 1: The hull unit CSH-5041 (400 mm transducer travel) can not be used.
Note 2: When some portion of the main shaft is cut off, the parts listed below should be
additionally ordered.
Name Type Code No.
Waterproofing attachment 10-044-2320-0 006-970-810
Lock-tight #601 000-856-120
The waterproofing attachment is supplied with the CSH-5040-FFx40.
Note 3: FF: Frequency, x: Retraction tank type
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 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 it. The
waterproofing attachment is not necessary. Note, however, that protrusion length of the
transducer is reduced.
2. Cut the main shaft to the necessary length.
· It is recommended to use a machine lathe to cut the main shaft.
