seachest. This can place addition strain on the
hoist motor and damage it. Also, if the insides of
the seachest start to rust the dome may jam and
possible damage to the hoist motor may be the
result. A loose fitting soundome will be subject to
vibration reducing sonar performance.
The SS395 soundome must fit the seachest with a
clearance no greater than 1/16 in (1.6 mm). Both
the 6 in and 8 in ABS soundomes have fins or ribs
on the side of the dome. The fins can be filed down
for the correct fit.
When checking the soundome, do not handle the
soundome by the soundome cable. Hold the dome
by the neck.
2.3.3 Fasten the soundome to
the soundome tube
1. Thread the jam nut into the soundome.
2. Wrap teflon tape around the threads of the soun-
dome tube. WARNING: only use Teflon tape
on the threads of the soundome tube. Chemical
thread sealant will damage the ABS threads of the
soundome.
3. Run the soundome cable all the way through the
soundome tube, starting from the threaded end.
Have a helper hold the soundome at the same time
rotate the soundome tube. Be careful not to cross
threads. Tighten by hand without tools.
4. Tighten the jam nut using a wrench for a snug
fit.
5. To protect the soundome cable from chafing on
the end of the soundome tube, a urethane strain
relief is supplied. Cut the urethane strain relief
down one side. Open the cut and push the soun-
dome cable into the strain relief. Slide the strain
relief down the cable and into the open end of the
soundome tube.
