    INSTALLATION INSTRUCTIONS Thru-Hull Depth Transducer Low Profile, Flush, and Retractable Models IMPORTANT: Please read these instructions completely before proceeding with the installation. These directions supersede any other instructions in your instrument manual if they differ. WARNING: NEVER USE SOLVENTS! Certain cleaners, fuel, paints, sealants, and other products may contain strong solvents, such as acetone, which attack many plastics greatly reducing their strength.
  • Page 6: Mounting Location

    Mounting Location Acoustic Noise Acoustic noise is always present and these sound waves can interfere with the operation of the transducer. Background noise from sources such as: waves, fish, and other vessels cannot be controlled. However, carefully selecting the transducer mounting location can minimize the affect of vessel generated noise from the propeller(s) and shaft(s), other machinery, and other echosounders.
  • Page 7: Boat Types

    Boat Types (see Figure 1) Displacement hull powerboat—Locate 1/3 aft LWL and 150–300mm (6–12") off the centerline on the side of the hull where the propeller is moving downward. Planing hull powerboat—Mount well aft, on or near the centerline, and well inboard of the first set of lifting strakes to insure that the transducer is in contact with the water at high speeds.
  • Page 8: Fairing

    Fairing Generally, the sensor is mounted without a fairing. However, a fairing does provide a level mounting surface. Nearly all vessels have some deadrise angle at the transducer mounting location. If the transducer is mounted directly to the hull, the sound beam will be tilted off the vertical at the same angle as the deadrise angle.
  • Page 9: Bedding

    Bedding Caution: Never pull, carry, or hold the transducer by its cable; this may sever internal connections. Remove the hull nut and any washer (see Figure 2). Also remove the cap nut and the transducer insert. Apply a 2mm (1/16") thick layer of sealant around the lip of the housing that contacts the hull and up the sidewall of the housing, 6 mm (1/4") higher than the combined thickness of the hull, washer(s), and the hull nut.
  • Page 10: Checking For Leaks

    Warning: Always attach the safety wire to prevent the insert from backing out in the unlikely event that the cap nut fails or is screwed on incorrectly. Attach the safety wire. Attach the safety wire to one eye in the hull nut. Lead the wire in a counterclockwise direction and thread it through one eye in the cap nut, the pull ring, the second eye in the cap nut, and the second eye in the hull nut.

    Installation in a Cored Fiberglass Hull The core (wood or foam) must be cut and sealed carefully. The core must be protected from water seepage, and the hull must be reinforced to prevent it from crushing under the hull nut allowing the housing to become loose. Warning: Always wear safety goggles and a dust mask.
  • Page 12: Connection To Instrument/Contacts

    CONNECTION TO INSTRUMENT/CONTACTS The depth transducer connects to the FI-30 Server or directly. The transducer cable is clearly marked with No 2 and the colours will correspond to input screw terminal on the Server. IMPORTANT! DO NOT CUT OR EXTEND THE 8 M TRANSDUCER CABLE! Calibration Calibration is carried out in the Multi Control instrument (see manual).
