Appendix 3 Installation Of Transducer B54 - Furuno DFF-3D Operator's Manual

APPENDIX 3 INSTALLATION OF
TRANSDUCER B54
This appendix provides a copy of the installation instructions and Installation supplement for the
®
AIRMAR Technology Corporation Transducer B54. For the latest version of these instructions,
see the materials provided with the transducer.
B54 Depth Transducer
The anti-rotation bolt holds the fairing firmly in place. Failure to install the anti-
rotation bolt may result in the fairing rotating while the boat is underway. The
effect may be violen t movement and loss of steering. This could result in serious
injury or death to passengers and/or damage to the boat or other property.
Follow the precautions below for optimal product
performance and to reduce the risk of property damage,
personal injury, and/or death.
WARNING: A High-Performance Fairing must be installed
following the installation instructions that accompany the fairing.
WARNING: Always wear safety goggles, a dust mask, and
ear plugs when installing.
WARNING: The fairing must be installed parallel to the keel
to ensure proper boat handling.
WARNING: Do not install a fairing that has been mis-cut.
Replace it.
• Cutting the fairing at an angle greater than the maximum
allowed will cut into the transducer and/or bolt pocket,
thus weakening the fairing.
• Do not allow any gap between the fairing and the hull that is
greater than 3mm (1/8"). When the boat is underway,
water will enter any gaps and push against the fairing with
considerable force, possibly rotating it.
WARNING: Immediately check for leaks when the boat is
placed in the water. Do not leave the boat unchecked for
more than three hours. Even a small leak may allow
considerable water to accumulate.
CAUTION: Never mount a bronze transducer in a metal hull,
because electrolytic corrosion will occur.
CAUTION: Never install a bronze transducer on a vessel
with a positive ground system.
CAUTION: Never pull, carry, or hold the transducer by the
cable as this may sever internal connections.
CAUTION: Never strike the transducer.
CAUTION: Do not over-tighten the hull nut and the nut on
the anti-rotation bolt, crushing the fairing and/or hull.
CAUTION: The transducer and the yellow triangular plug
must be flush with the fairing for smooth water flow under the
transducer.
CAUTION: Never use solvents. Cleaner, fuel, sealant, paint,
and other products may contain solvents that can damage
plastic parts, especially the transducer's face.
IMPORTANT: Read the instructions completely before
proceeding with the installation. These instructions supersede
any other instructions in your instrument manual if they differ.
