7INSTALLATION Step FourOMEGA ENGINEERING's LVP‐51‐R level switch may be installed anywhere on a tank wall using the PE (LVP‐91)or PP (LVP‐92) bracket that the switch slides into. The bracket comes with adhesive on the tank side that issufficient to hold the sensor in position temporarily while the installation is tested, but for permanentinstallation the bracket must be welded, glassed or strapped to the tank. Extra brackets are available fromOMEGA ENGINEERING, so that the level switch may be moved to different locations on the tank by sliding itinto other brackets.Attach the bracket to the tank:1. Determine whether the tank is PP or PE. The slide‐in fitting shipped with the sensor is determined bythe part number. If necessary, obtain an additionalbracket.2. Determine the mounting location for the level switch. Thepoint of actuation (where the sensor will send a “wet”signal) is most often at the center of the sensor; howeverthe actual Point of Actuation (POA) may differ dependingon the application liquid and tank wall characteristics.After positioning the fitting to check clearances, etc.,remove the paper protective strips from the adhesive ofthe bracket.3. Press the bracket into place. The adhesive provides a sealbetween the sensor and the tank wall, and will hold it inplace during testing and installation. If desired, the sensor may be installed temporarily withoutwelding the fitting to the wall. If several different locations must be tried before permanentinstallation, use double‐sided foam stick tape designed for PP or PE.4. After the sensor has been tested to verify the POA, weld, glass or strap the bracket to the tank usingstandard industrial plastic techniques.Special note for small round tanks: The bracket may be attached to small, round tanks, as long as themajority of the bracket is firmly attached to the wall. However, extreme installations may affect the switchesperformance.Mount the sensor in the bracket:1. Slide the sensor into the bracket.2. After trimming the sensor wire to length if needed by the installation, thread the sensor wire into aplastic flexible conduit with a 1/2" male fitting. Screw the conduit into the sensor, being careful not tocross the threads. Do not over tighten the conduit in the sensor as this may break the fitting. Suchdamage is not covered by the warranty. Take care while pulling the wire through conduit that noexcessive tension is placed on the sensor end of the wire, so that the wire is not broken from thesensor housing.3. Connect the sensor wire to the controller following the instructions in its manual. See the followingWiring Section for detailed wiring instructions.
