NSTALLATION - 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 as-
sembly 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 com-
pound to the transducer’s contact surface. Place the transducer between the track rails, slightly be-
hind the pin and under the clamping screw assembly. Slide it forward until it butts up firmly against the
reference pin.
