Mount the Transducer Cable Gland
See Figures 11 and 12.
In the external sea chest and fairing type installations, the cable gland forms a
seal where the transducer cable passes through the hull. In low profile sea chest
installations, the gland passes through the sea chest cover.
The gland pipe and a single gasket are the only parts of the gland that are located
inside the sea chest or outside the hull, all other parts are attached to the gland pipe
inside the vessel.
Mounting Instructions
Depending on the type of installation, there are various ways of mounting the cable
gland to the hull. The following example describes how to mount the gland through
the hull and then feed the cable through the gland. Adapt the following procedure
to suit your installation while taking the following into consideration:
►
Always use a good quality marine sealant to seal across areas that can leak.
►
When installing the gland packing ring, apply soapy water to the inside of the
packing ring and pass it over the transducer cable until it is sitting on top of the
gland pipe. The soapy water allows the packing ring to slide easily down the
cable. When sitting on top of the gland pipe, clean as much of the soapy water
off as possible to ensure the packing ring grips the cable when pressure is
applied by the gland nut.
►
Tighten the gland nut by hand until secure. With the vessel in the water, check
for leaks at the gland and if leaking slightly, tighten the gland nut with a spanner
until the leak stops.
►
When all leaks are stopped, tighten the gland lock nut against the gland nut.
STEP 1 Place the bottom gasket over the gland pipe and apply marine sealant to
both sides of the gasket. See Figure 11.
Push the gland pipe into the hole.
STEP 2 Place the top gasket over the gland pipe and apply marine sealant to
both sides of the gasket.
Place the plate over the gland pipe and onto the top gasket.
Screw the lock plate onto the gland pipe until a good joint is achieved.
Clean away any excess marine sealant.
STEP 3 Feed the transducer cable through the gland.
See Figure 12 for a set of steps to feed a
RJ-45 type
cable through the
gland pipe.
STEP 4 Screw the gland lock nut as far as it can go onto the gland pipe.
Place the gland packing ring over the cable until it sits on top of the gland
pipe.
Place the gland nut over the cable and screw the nut onto the gland pipe
firmly by hand.
STEP 5 With the vessel in the water, check for leaks at the gland and if leaking
slightly, tighten the gland nut with a spanner until the leak stops.
With all leaks stopped and while holding the gland nut with a spanner,
tighten the gland lock nut against the gland nut with a spanner.
