Be sure to turn the power off before starting the installation. Further, it is highly recommended that you keep power off while you're performing the installation. If power is left on or turned on during the installation, fire, electrical shock, or other serious injury may occur. Be sure to ground the equipment to prevent electrical shock and mutual interference. Be sure the transducer outputs are tied together before handling to avoid electrical charge build-up. WARNING! Be sure to use a 3-amp fuse. Using the incorrect fuse can result in fire or damage to the 490. 490 INSTALLATION MANUAL, Revision B2 Page 5 SECTION TWO Installing the transducer CAUTION! Mounting the transducer requires drilling holes through the hull; make sure the installation does not cause the vessel to leak. A thru-hull installation should be performed by a professional installer. Do not attempt this unless you are fully qualified. Do not perform a thru-hull installation of the transducer when the vessel is actually in the water. Immediately after installing the transducer, be sure to check for leaks, and don't leave the vessel in the water for more than three hours before checking it again. Northstar assumes no responsibility for improper installation of a transducer. NOTE: Be sure that the transducer doesn't interfere with any of the on-board systems. Check all other systems to ensure that their performance doesn't degrade when the transducer is connected. Selecting a transducer Northstar recommends using an Airmar transducer with the Northstar's 490 echo sounder.

To ensure that you meet all critical installation parameters, be sure to read and follow all of the requirements in their instructions. Northstar assumes no responsibility for improper installation. Choosing a mounting location CAUTION! Do not mount the transducer: · behind strakes, fittings, or hull irregularities (mounting in those locations may increase turbulence, aeration, and cavitation) or near the keel · near openings for water intake or discharge · where it might be loosened by the vessel's vibration · less than four feet away from the Northstar 961/ 962 processor to minimize interference 490 INSTALLATION MANUAL, Revision B2 Page 7 SECTION TWO Installing the transducer The two most common problems with echo sounder installations stem from noise and cavitation. Either of these situations can produce poor performance. Noise occurs when the transducer cable is routed too closely to noise-producing electronics, such as alternators, AC generators, radars, etc. To avoid problems with noise, route the transducer cable by itself (not in a bundle) and away from other wires or cables and the engine. Cavitation is similar to hydroplaning. In some cases, air bubbles will come between the transducer and the water. When this happens, the transducer can't get its energy into the water properly, and won't be able to detect any echoes. To avoid cavitation, choose a mounting location with good water flow all around it at all speeds. Choose the mounting location to obtain the best possible performance from the transducer and the 490. Take into account the vessel's maximum speed when selecting a mounting location, as turbulence can affect echo sounding capabilities. Before any drilling or cutting takes place, carefully choose a mounting location for the transducer that meets the following criteria (also see Figure 1 on page 9), depending on the type of vessel: · · · the transducer and its cable are as far as possible from other electrical cables leaves room above the transducer for the transducer's stem, housing, and cable the path for running the transducer's cable is reasonably direct--keep in mind that the transducer cable is 33 feet long (10 meters). To prevent damage, coil any excess cable and secure it water turbulence and noise are minimal, decreasing the amount of bubbles passing over the transducer face the transducer isn't behind hull irregularities or near eroding paint; both indicate areas subject to turbulence the transducer is as far as possible from the engine or propellers, and inboard of the lifting strakes the transducer always remains submerged and perpendicular to the waterline the transducer is easily accessible from inside the vessel for adjustments and maintenance the transducer's ultrasonic beams aren't obstructed by the keel, propeller shafts, or any other part of the vessel the transducer is parallel with the water surface the hull thickness falls within the limits in Table 2 below (all dimensions are perpendicular to the waterline): · · · · · · · · Page 8 490 INSTALLATION MANUAL, Revision B2 SECTION TWO Installing the transducer Table 2: Hull thickness limits Model AirMar B44V/B744V with fairing AirMar B44V/B744V without fairing AirMar B250 with fairing AirMar B250 without fairing Minimum 6 mm (1/4 inch) 6 mm (1/4 inch) ---- 19 mm (3/4 inch) Maximum 19 mm (3/4 inch) 65 mm (2 1/2 inches) 45 mm (1 3/4 inches) 114 mm (4 1/2 inches) pressure waves 1/3 aft LWL (Load Waterline Length) displacement hull 150-300mm (6-12") outboard and I/O planning hulls inboard step-hull fin keel sailboat full keel sailboat Best location for the transducer Figure 1: Recommended installation locations for a transducer 490 INSTALLATION MANUAL, Revision B2 Page 9 SECTION TWO Installing the transducer Installing a transducer A flat-bottom hull provides the best environment for mounting the transducer: It provides a horizontal surface and a constant water flow over the transducer, with little turbulence (see Figure 2 for the recommended transducer incline angle). If the vessel has a deadrise angle greater than 5 degrees, mount the transducer on a fairing block to create a horizontal surface and keep the transducer perpendicular to the waterline (see Figure 3). You must order the fairing block, if needed, from the transducer's manufacturer. 3° incline angle 1/3 aft LWL (Load Waterline Length) Figure 2: Recommended transducer incline angle backing block slope of hull deadrise angle parallel to waterline fairing hull fairing thickness at narrowest point 6­12mm (1/4­1/2") multisensor Deadrise angle and fairing thickness (B44V shown) Figure 3: Typical finished thru-hull installation with a fairing block (Airmar B44V) Page 10 490 INSTALLATION MANUAL, Revision B2 SECTION TWO Installing the transducer Maintaining a transducer Using anti-fouling paint Do not expose the transducer's face or plastic housing to gasoline or strong solvents, such as acetone. These solvents can penetrate and degrade many plastics and reduce their strength. The transducer should be coated with water-based anti-fouling paint to prevent aquatic growth. housing paddle wheel insert Paint exposed housing and bore up 30mm (1-1/4") detail lower O-ring Paint outside wall below the lower O-ring including exposed end, paddle wheel cavity and paddle wheel Anti-fouling paint (B44V shown) Figure 4: Anti-fouling paint areas (for Airmar B44V) CAUTION! Use special transducer paint. Other paints may contain copper, which is conductive and can burn out the transducer within minutes! Cleaning a transducer To clean the transducer of heavy debris or foul sea growth, use a stiff brush or putty knife, but don't scratch the surfaces. Check the transducer every few weeks, maximum. Use sanding sparingly, as repeated sanding may affect the transducer's performance at high speeds. For lighter cleaning, the surface may be wet-sanded with #220 or finer wet/dry sandpaper. 490 INSTALLATION MANUAL, Revision B2 Page 11 SECTION TWO Installing the transducer Page 12 490 INSTALLATION MANUAL, Revision B2 SECTION THREE Installing the 490 Safety considerations WARNING! Be sure to turn the power off before starting the installation. Further, it is highly recommended that you keep the power off while you're performing the installation. If power is left on or turned on during the installation, then fire, electrical shock, or other serious injury may occur. Be sure to ground the equipment to prevent electrical shock and mutual interference. Be sure that the voltage of the power supply is between 10 and 30 volts DC. Connecting to the wrong power supply can result in fire or damage to equipment. Be sure to use a 3-amp fuse. Using the incorrect fuse can result in fire or damage to the 490. CAUTION! Keep the following safe compass distances from the 490: 1.0 m standard, 0.8 m steering. 490 INSTALLATION MANUAL, Revision B2 Page 13 SECTION THREE Installing the 490 CAUTION! Be sure that the 490 doesn't interfere with any of the on-board systems. Check all other systems to ensure that their performance doesn't degrade when the 490 is turned on. If the vessel is out of the water when the echo sounder is turned on, the transducer may be damaged. CAUTION! Do not open the 490. There are no serviceable parts inside. Unauthorized tampering with the unit will automatically void the warranty.

The rise of the bottom of a vessel above a horizontal line at the center of the vessel; that is, the slope of the hull away from the horizontal. An instrument that uses sound waves to measure the depth of a body of water or an object (such as a school of fish) below the water's surface. A block used to create a horizontal surface for mounting a thru-hull transducer when the vessel's deadrise is more than 5 degrees. The device mounted through the hull to send and receive ultrasonic beams that determine seabed conditions and locate fish. Essentially, a transducer is an energy converter, which changes electricity to sound (send) and sound to electricity (receive). deadrise echo sounder fairing block transducer 490 INSTALLATION MANUAL, Revision B2 Page 31 Glossary water column An imaginary column through the water created by the path of a single transducer ping and its echoes.
