4. MOUNTING PROCEDURE Warning In order to achieve proper results with this type installation it is important that the transducer be mounted by someone familiar with the use of two part epoxy adhesives For this reason Techsonic Industries Inc will not be responsible for any damage due to the mounting of your transducer in this manner NOTE An Epoxy Kit Part N EPK is available from Humminbird This Epoxy Kit has been formulated for Inside Hull Transducer Installation 1 Select as flat an area as possible near the aft end and center of boat where the hull is thin and not double If the bottom has a runner down the center of boat select an area to one side of the runner but as close to the runner as possible 2 Clean the inside of the boat with lacquer thinner in the area transducer is to be mounted Outside of boat in this area should also be cleaned Not with lacquer thinner 3 Put approximately one inch of water in the bottom of the boat 4 Puttransducer in the water The bottom of the transducer should be in a flat area and should be in good contact with the bottom of the boat 5 Operate the LCR with the boat operating at high speed The transducer may have to be moved in order to find an area where satisfactory operation is observed 6 When an area is found that produces satisfactory operation mark the location of the transducer 7 Remove the water and transducer and clean the marked area and the bottom of the transducer tho

21. rolling motor Mount This type of transducer is not supplied with your LCR It is designed to mount on the foot of a trolling motor You may exchange your un used high speed transducer for a trolling motor transducer Call the Humminbird Customer Service Department D Bronz Thru Hull Mount This transducer is not supplied with your LCR but for an additional cost you may exchange your un used high speed transducer for a bronz thru hull The bronz thru hull transducer has a threaded stem which installs through a hole drilled in the boat hull leaving the housing exposed under the boat This type of installation must be used for many boats with in board engines because there is no suitable location on the transom away from the noise and turbulence created by the prop A bronz thru hull transducer should be installed by qualified personnel only The LCR will operate well at high speeds with a properly mounted transducer Remember a transducer will not work transmitting through air or through air bubbles 1 TRANSOM MOUNTING PROCEDURE Step 1 MOUNTING LOCATION It is important that the transducer be mounted on the transom where water flow is in constant contact with the transducer You may wish to observe the rear of the boat while it is moving through the water to determine the best mounting location Step 2 BRACKET INSTALLATION Aluminum Boats To install the metal bracket on an aluminum boat locate the template on the transom between rows of r
22. roughly 8 Using the Humminbird Epoxy Kit or equivalent mix an ample amount of epoxy without causing it to bubble and pour it in the area the transducer is to be mounted The puddle should be larger than the bottom of the transducer 9 Coat the bottom of the transducer with epoxy then put it in the center of the puddle and push down on the transducer while moving it around in a circular motion This forces out any air bubbles that may be trapped between the bottom of the transducer and the hull of the boat 10 Let epoxy cure then the transducer is ready to operate No water is now required in the bottom of the boat and gas and oil that is spilled inside of the boat will not degrade performance as it will if the transducer is placed only in water CAUTION Do not use the silicone seal or any soft adhesive to bond the transducer to the hull This will reduce the sensitivity of the unit CAUTIONS 1 Occasionally the eye of your transducer may become dirty from storage or from contact with oils present in boats or marina environments Oil will cause the eye to lose the intimate contact with the water which is necessary for efficient operation The eye may be cleaned with liquid detergent 2 Improper installation of the transducer can alter the efficiency and accuracy of the entire system 3 If your boat of transducer is out of the water for a period of time it may take a short period of time for the transducer to become thoroughly
