STEP 4: Dismantle the sensor adapters
Remove the sensor adapters' rubber inserts (two) before
performing any hot work. Locking devices and internal plastic
spacers may remain attached.
Over heating of either the sensor adapters or doors must be
avoided though out the installation procedure.
The two rubber inserts provided must not be replaced with any
other types or designs. It is essential that these inserts provide a
secure cradle for the sensors, but they must also allow for free
water circulation to allow the sensor's water switch to engage.
Also, the design of the inserts allows sand and mud to flow out
when the trawl doors are pulled up from the water.
