7. Fully tighten the nut and bolt.
Do not exceed a torque of 35 N·m (25.8 lbf·ft). The transducer should not
be easily moveable by hand, and should remain in its normal operating
position when your vessel is underway.
7.8 Anti-fouling
Where local regulations allow, it is recommended that you coat your
transducer using a water-based anti-fouling paint. This will help prevent the
build-up of organic growth, which can reduce transducer performance.
Important:
• Before applying water-based anti-fouling paint, check that local
environmental rules and regulations do not prohibit the use of anti-fouling
paint.
• Never use copper-based anti-fouling paint as this can impact transducer
performance.
• Never use ketone-based anti-fouling paint as this can attack the
transducer’s plastic, damaging the transducer.
• Paint your transducer using a brush, do not use a spray can or a sponge
roller as these methods can cause tiny air bubbles to be incorporated in
the paint, which will also reduce transducer performance.
The anti-fouling paint should be applied in a thin and even coat covering all
externally exposed transducer surfaces.
You should clean your transducer regularly and re-apply anti-fouling paint
every 6 months, or sooner depending on how rapidly organic growth builds
up.
