Furuno SS542 Owner's Manual & Installation Instructions

OWNER'S GUIDE & INSTALLATION INSTRUCTIONS
Thru-Hull Mount
Installation of the anti-rotation bolt is mandatory!
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 violent 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: The transducer must be installed with a High-
Performance Fairing.
WARNING: When installing the High-Performance Fairing
carefully follow these installation instructions.
WARNING: Always wear safety glasses, a dust mask, and
ear protection 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: Stainless steel transducer in a metal hull—
Use sleeving to isolate the stainless steel transducer and
anti-rotation bolt from the metal hull. Failure to do so will
cause electrolytic corrosion.
CAUTION: Never pull, carry, or hold the transducer by the
cables as this may sever internal connections.
CAUTION: Never strike the transducer.
Multi-beam Sonar & Depth Transducer
Model SS542
WARNING
with Temperature Sensor & High-Performance Fairing
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.

Applications

• Stainless steel transducer compatible with all hull materials.
Recommended for aluminum hulls to prevent electrolytic corrosion
provided the stainless steel transducer is isolated from the metal hull.
• Maximum deadrise angle of 20°.
