User manual HUMMINBIRD PIRANHA 5 INSTALLATION

[. . . ] PIRANHA 5 INSTALLATION GUIDE Two components need to be installed on the boat: the transducer and the control head. The control head displays sonar information, the transducer sends and receives sonar signals into the water. Proper installation of each insures best performance of the Piranha and provides the greatest enjoyment and functionality. Hold the template on the transom of the boat in the location where the transducer will be installed. [. . . ] Insert the Pivot Bolt through the Pivot Knuckle on the control head. Thread the Gimbal Knob onto the Pivot Bolt using only 2-3 turns. Using Allen wrenches to set running angle 3. Align the Pivot Knuckle with the Mount Base Arms and slide into place until it seats firmly. A slight twist will aid in seating the unit. Rotate the Control Head to the desired angle and hand tighten the Gimbal Knob. Now you can use the assembled Piranha to identify the best mounting location. Drill the hole for and hand tighten the third mounting screw only after highspeed testing. Pivot Bolt Gimbal Knob Pivot Knuckle Figure 8 2 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. Transducer extension cables are available. The power cable can be shortened or lengthened with 18 gauge wire. · 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. · 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. Cabling can be routed through a /" hole centered between the two rear mounting holes of the base. STEP 5: INSTALL THE BASE 1. 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. Unscrew only enough to permit the unit to release. Using the mount base as a template, mark the location for the mounting holes. Drill the mounting holes using a /" (3. 6mm) bit. Drill a /" hole at the location where the cables pass through the mounting surface. If access is possible underneath mounting surface, drill the hole so the mount base forms a hole cover. See Figure 9 for location of cable hole under the mount. Pass the transducer and power cables through the /" inch hole, leaving about 6" length above the surface. Align the mount base with the holes and attach with the Phillips screws provided. STEP 6: ATTACH THE CONTROL HEAD AND PLUG IN CONNECTORS 1. [. . . ] · If the bracket is fully extended and high-speed performance continues to need adjustment, incrementally change the Pivot Angle to lower the rear of the transducer by ¹/" steps until best high-speed performance is achieved. Important: For transom mount transducers, install the third mounting screw after final transducer adjustments. Once the mounting location is determined, mark the position of the transducer. Remove the water from inside the hull and thoroughly dry the mounting surface. [. . . ]
