HUMMINBIRD INSTALLATION GUIDE There are three basic installation tasks that you must perform for the Humminbird Fishing System: · Installing the Humminbird control head · Installing the transducer · Testing the complete installation and locking the transducer position. The transducer can either be installed inside the hull, on the transom of the boat, or onto a trolling motor, depending on your transducer type. You will want to install the included Temperature/Speed accessory, using the separate installation instructions included with the accessory. NOTE: If the included transducer will not work for your application, you may exchange it, NEW and UNASSEMBLED, with mounting hardware included, for a transducer appropriate for your application - often at very little or no charge depending on the transducer. Call the Humminbird Customer Resource Center (1-800-633-1468) for details and pricing, or visit www.humminbird.com, Product Support/Transducer Exchange for more information. NOTE: Due to the wide variety of hulls, only general instructions are presented in this installation guide. Each boat hull represents a unique set of requirements that should be evaluated prior to installation. In addition to the parts supplied, you will need a powered hand drill with various bits, Phillips and flat-head screwdrivers, a ruler or measuring tape, pen or pencil, and marine-grade silicone sealant. NOTE: Please read all instructions carefully and completely before beginning the installation process. NOTE: When drilling holes in fiberglass hulls, it is best to start with a smaller bit and use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating. top of the mounting bracket (Figure 7). Using needle-nose pliers, break out the tabs on the rear of the mounting base (Figure 8). Place the Hole Cover over the mounting surface hole, then use it to mark the position of the two mounting screws. Remove the Hole Cover, drill the two mounting holes using a /" (3.5 mm) bit, fill them with marine-grade silicone, then replace the Hole Cover and insert the #8 Phillips countersink wood screws. Hand-tighten only. 2. Place the mounting bracket on the mounting surface aligned with the drilled holes and fill the mounting holes with marine grade silicone. Insert the four #8 Phillips countersink wood screws into the mounting holes. Hand-tighten only. 3. 1. Break-out tabs Assemble the Transducer 7. Final Testing NOTE: Call the Humminbird Customer Resource Center (1-800-633-1468) for details and pricing, or visit www.humminbird.com for more information. Figure 8 Connector Holder Transducer Communications Accessory Power Attach the pivot to the transducer body as shown in Figure 18, using the two ¹/"-20 x /" (16 mm) machine screws, toothed washers, and square nuts. The toothed washers must fit on the inside of the transducer ears, between the pivot and the ears. The square nuts will be prevented from rotating by the pocket in the back of the pivot. An Allen wrench is provided which fits all the ¹/"-20 screws, but do not fully tighten the screws at this time. After transom transducer installation, please perform the final testing and then finalize the installation (see Test and Finish the Installation). TEST AND FINISH THE INSTALLATION When you have installed both the control head and either the transom or the trolling motor transducer, and have routed all the cables, you must perform a final test before locking the transducer in place. Testing should be performed with the boat in the water, although you can initially confirm basic operation with the boat out of the water. NOTE: If you have installed an in-hull mount transducer, this procedure does not apply, as the transducer is already locked in place. INSIDE THE HULL TRANSDUCER INSTALLATION In-hull mounting generally produces good results in single thickness fiberglass-hulled boats. Humminbird cannot guarantee depth performance when transmitting and receiving through the hull of the boat, since some signal loss occurs. The amount of loss depends on hull construction and thickness, as well as the installation position and process. This installation requires slow-cure two-part epoxy. Do not use silicone or any other soft adhesive to install the transducer, as this material reduces the sensitivity of the unit. Do not use five-minute epoxy, as it has a tendency to cure before all the air bubbles can be purged, thus reducing signal strength. NOTE: In-hull mounting requires an installed and operational control head. 5. 1. 4. 1. Mount the Transducer Assembly to the Transom 1. Assembling the Connector Holder Figure 9 Insert both the power and the transducer cable plugs into the connector holder. The cable plugs are labeled, and there are corresponding labels on the connector holder (Figure 9). The slots for the plugs are keyed to prevent reverse installation, and insertion should be easy - do not force plugs. Slide the assembled transducer into the metal bracket from the bottom, aligning the large hole at the top of the bracket with the hole in the pivot as shown in Figure 19. Press POWER once to turn the control head on. There will be an audible chirp when the button is pressed correctly. If the unit does not power-up, make sure that the Connector Holder is fully seated in the receptacle and that power is available. 2. Insert the headed pin through the pivot holes in the bracket and pivot. The headed pin can be inserted from either side of the bracket. 3. Place the nylon washer over the opposite end of the headed pin. Place the stainless washer over the ¹/"-20 x /" (0.016 mm) screw threads, then insert into the opposite end of the headed pin and finger tighten only. The screw has a thread locking compound on the threads to prevent loosening, and should not be fully tightened until all adjustments are made. NOTE: The running position of the transducer is now completely adjustable. Subsequent adjustment may be necessary to tweak the installation after high speed testing. The metal bracket allows height and tilt adjustment, the pivot screws allow angle adjustment. Figure 18 1. Determine the Transducer Mounting Location 2. If all connections are correct and power is available, the Humminbird control head will enter Normal operation. If no transducer is detected (or one is not connected), the unit will go into Simulator mode and will indicate this by displaying the word Simulator on the control head display. NOTE: The transducer must be submerged in water for reliable transducer detection. Transducer Mounted Inside the Hull Connector Holder Cable Connector 2. Carefully pull the excess cable from beneath the mounting surface so that the connector holder aligns with the mounting holes on the front of the mounting bracket (Figure 10). 3. Snap the support plate onto the rear of the connector holder (Figure 11). 4. Insert the connector holder into place and fasten it to the mounting bracket using the two #6-32 x ³/" (19 mm) screws (Figure 12). Hand-tighten only. 5. Slide the control head onto the mounting bracket until it is fully seated. To remove the unit, grasp the unit with both hands, then firmly press the latch on the rear of the unit and lift (Figure 13). NOTE: This latch is heavy-duty to withstand marine use, and significant force must be applied. Decide where to install the transducer on the inside of the hull. Consider the following to find the best location: · Observe the outside of the boat hull to find the areas that are mostly free from turbulent water. Avoid ribs, strakes and other protrusions, as these create turbulence (Figure 14). · As a general rule, the faster the boat can travel, the further aft and closer to the centerline of the hull the transducer has to be located in order to remain in contact with the water at high speeds (Figure 25). Figure 24 Preferred Mounting Area 3. If the bottom is visible on-screen with a digital depth readout, the unit is working properly. Make sure that the boat is in water greater than 2' but less than the depth capability of the unit, and that the transducer is fully submerged, since the sonar signal cannot pass through air. 4. If the unit is working properly, gradually increase the boat speed to test high-speed performance. If the unit functions well at low speeds but begins to skip or miss the bottom at higher speeds, the transducer requires adjustment. Angling the rear of the transducer downward and/or lowering the transducer farther into the water will help achieve depth readings at high speeds. NOTE: It is often necessary to make several incremental transducer adjustments before optimum high speed performance is achieved. Due to the wide variety of boat hulls, however, it is not always possible to obtain high speed depth readings. Figure 10 Figure 19 Support Plate 5. Figure 11 Adjust the Running Position of the Transducer 2. Cavitation that will cause erratic sonar readings Trial Installation 531340-1_A The transducer mounting bracket allows height and tilt adjustment, while the pivot bolt allows angular adjustment. These adjustments will help reduce cavitation (Figures 20 and 21). Initially, adjust the transducer as described in the following paragraphs. Further adjustment may be necessary to refine the installation after highspeed testing. 1. First, adjust the pivot angle of the transducer body, so it is parallel with the length of the hull of the boat. Figure 20 You will not be able to adjust the mounting after an inside the hull transducer is installed. It is best, therefore, to perform a trial installation first that includes running the boat at various speeds, in order to determine the best mounting area before permanently mounting the transducer. 1. Once you have reached a consistently good sonar signal at the desired speeds, you are ready to lock down the transducer settings. 5. Mark the transducer bracket location on the transom with a pencil, then pop up the bracket to reveal the mounting screws. Tighten the stainless steel mounting brackets screws to secure in place. Hand-tighten only. Figure 25 CONTROL HEAD INSTALLATION You are now ready to install the transducer. Find the section that refers to your transducer type. Plug the transducer into the control head, then power up the control head. When the control head detects a functioning transducer, it will automatically enter Normal operating mode. 1. Determine Where to Mount Begin the installation by determining where to mount the control head. Consider the following to determine the best location: · To check the location planned for the control head, test run the cables for power, transducer and Temp/Speed accessory (if applicable). See the installation section for your transducer type in order to plan the location of the transducer. · There are two ways to route the cables to the unit: through a hole in the mounting surface underneath the mounting bracket, or from a hole outside the mounting bracket. Routing the cables under the mounting bracket provides maximum weather protection; this may not be feasible, however, if the area under the control head is inaccessible. In this case, route the cables through a hole at another location and cover with the supplied hole cover. · The mounting surface should be stable enough to protect the control head from excessive wave shock and vibration, and should provide visibility while in operation. · The mounting area should allow sufficient room for the unit to pivot and swivel freely, and for easy removal and installation (Figures 1 and 2). Figure 2 TRANSOM TRANSDUCER INSTALLATION 1. 1. Figure 12 Determine Transducer Mounting Location NOTE: If transom mounting is not possible because of a stepped hull or cavitation noise, and you have a single layer fiberglass hull, In-hull installation is an option. See Inside the Hull Transducer Installation for more information. 2. Fully tighten the two pivot screws, using the supplied Allen wrench. Access to the pivot screws is provided by the lower holes in the side of the mounting bracket. It may be necessary to re-tighten the pivot bolt after initial use as the plastic may still be conforming to the pressure from the lock washers (Figure 22). 3. Adjust the height of the assembly so the face of the transducer is ¹ " (3 mm) to ¹ " (6 mm) beneath the bottom of the transom, and fully tighten the three mounting screws (Figure 22). 4. In order to gain access to the mounting screws, the transducer assembly must be pivoted up in the bracket as shown. Be careful not to alter the running angle as some force is necessary to pivot the assembly (Figure 22). 5. If access to the top mounting hole is not possible due to the selected height of the transducer, fully tighten the two lower screws, then simply remove the headed pivot pin and the transducer assembly, and tighten the top screw, then reassemble. 6. Confirm that the pivot angle has not changed and that all mountin ...
