WARNING: A safe installation requires a 0.5 amp fast-blow fuse or circuit
breaker.
WARNING: The power supply voltage must be 9 - 16 VDC.
CAUTION: The sensor is NOT compatible with a bronze housing, because
bronze may cause interference resulting in incorrect readings.
CAUTION: Never pull, carry, or hold the sensor by its cable; this may sever
internal connections.
CAUTION: Plastic housing—Never use a fairing with a plastic housing;
the protruding sensor would be vulnerable to damage from impact.
CAUTION: Metal housing—Never install a metal housing in a vessel with
a positive ground system.
CAUTION: Stainless steel housing in a metal hull—Stainless steel
housing must be isolated from a metal hull to prevent electrolytic corrosion.
Use the isolation bushing supplied.
CAUTION: The sensor must be aligned within 1° of parallel to the
centerline/keel of the boat.
CAUTION: The arrow on the top of the insert must point forward toward
the bow area to align with the water flow.
CAUTION: The bottom of the insert must be flush with the bottom of the
housing. Note that the electrodes will protrude into the water.
CAUTION: Do not paint the face of the insert with the electrodes.
CAUTION: The sensor must be in good contact with the water at all times.
CAUTION: Never use solvents. Cleaner, fuel, sealant, paint, and other
products may contain solvents that can damage plastic parts, especially the
insert’s face.
IMPORTANT: Please read the Owner’s Guide completely before
proceeding. These instructions supersede any other instructions in your
instrument manual if they differ.
