User manual HUMMINBIRD PIRANHA 1 INSTALL GUIDE

[. . . ] · Stepped hulls require the transducer be mounted on the step if possible. · If propellers are forward of the transom, clear water may be impossible to find. A different transducer or mounting method should be considered, (see optional inside hull instructions below). Remove the mounting template from the last page of Operation Section (Page O-15). [. . . ] Cut out the transducer templates from the Piranha package printed template insert following the cutting directions for your boat hull. Adjust the height on the transom and the pivot bolt angle to match guides on the template as shown. Ensure the height and angle have not changed. Transducer Transducer bottom Hull 6" 150mm Note: Allow enough slack in the cable for the transducer to pivot. Route the cable to side of the transducer.

Figure 5 Figure 7 I-2 STEP 2: ATTACH THE CONTROL HEAD TO THE BASE 1. Align the Pivot Knuckle with the Mount Base Arms and slide into place until it seats firmly. Rotate the Control Head to the desired angle and hand tighten the Gimbal Knob. · Ensure enough space exists for easy control head installation and removal and for pivoting through its full range of motion. · The mounting area should be well supported to protect the fishfinder from wave shock and vibration. · Choose an area that provides good visibility for the Piranha. Now you can use the assembled Piranha to identify the best mounting location. STEP 4: ELECTRICAL CONNECTIONS A 2m (6') long power cable is included to supply power to the fishfinder. You may shorten or lengthen the cable using 18 gauge multi-stranded copper wire. Humminbird is not responsible for over current or over voltage failures. Pivot Bolt Gimbal Knob Pivot Knuckle Figure 8 Figure 10 GROUND POSITIVE Figure 11 STEP 3: DETERMINE CONTROL HEAD MOUNTING LOCATION When choosing a mounting location consider the following: · Power and transducer cables should be installed first and must reach the control head. · If possible, choose a location that provides access from below so above deck cable length is short, and the cable's hole can be covered by the mount base. Cabling can be routed through a 16mm hole centered between the two rear mounting holes of the base. The power cable can be connected to the boat's electrical system at two places: a fuse panel, usually located near the console, or directly to the battery. If a fuse terminal is available, use crimp-on type electrical connectors (not included) that match the terminal on the fuse panel. Attach the black wire to ground and the red wire to 12 VDC power (Figure 10). If you must wire the control head directly to a battery, be sure to install an inline fuse holder and use a one amp fuse (not included) for the protection of the unit (Figure 11). In order to minimize the potential for interference with other marine electronics a separate power source (such as a second battery) may be necessary. Remove the control head from the mount base by loosening the gimbal knob and pulling the unit from the base - a slight twisting motion will help to release it. Note: It is not necessary to completely remove the gimbal knob. Using the mount base as a template, mark the location for the mounting holes. Drill the mounting holes using a 3. 5mm (/") bit. Figure 9 I-3 4. Drill a 16mm (/") hole at the location where the cables pass through the mounting surface. [. . . ] If the unit does not power on, ensure the cable plugs are fully seated and there is power available. If the unit detects the transducer, Start-Up will be the default selection. Note: The transducer must be submerged in water for reliable transducer detection. Weight the transducer so it does not move while the epoxy is curing. When the epoxy cures, no water is necessary inside the hull. [. . . ]
