INSTALLATION - REFLECT MOUNT WITH MOUNTING TRACK
2. Place the track rail assembly on the top surface of the pipe at the location where you have
determined it would be mounted. Ensure that it is a smooth area without any raised spots
or seams. Holding the assembly in place, loop one of the roller chains under the pipe, pull it
around and maintain tension while slipping a link over the tension screw hook. Tighten the
tension screw enough to hold the assembly on the pipe, but still allow rotation. Repeat for
the other roller chain. Rotate the track rail assembly to the intended nine o’clock mounting
position on the pipe, then tighten both tension screws just enough to prevent rotation. Do
not overtighten.
3. Mark a generous area around the transducers (1/2-inch on either side and half again the
length front and back) with a pencil or chalk. Loosen and move the assembly away from
marked area. Prepare the two areas you marked by de-greasing the surface, if needed, and
removing any grit, corrosion, rust, loose paint or surface irregularities with the abrasive
pipe conditioning material provided. Clean the pipe of all debris and abrasive particles.
4. Insert the index pin into the reference hole. Select a transducer, apply a thin band of couplant
compound to the transducer’s contact surface. Place the transducer between the track rails,
slightly behind the pin and under the clamping screw assembly. Slide it forward until it
butts up firmly against the reference pin.
