Installing DMP-1 Dampening Material
1. Be sure the CFG-V clamping fixture is installed on the pipe
with the transducers as described in the section Installing the
V Series Clamping Fixture and Transducers on page 3-14.
With a marker, mark scribe lines on the inside edges of the
brackets onto the pipe. These lines indicate where to apply the
material. (One 9.5-in. roll fits between the brackets.)
2. Remove the fixture and transducers.
3. Use a dry towel or rag and thoroughly dry the pipe.
4. Unroll the DMP-1 material and cut off a length equal to the
circumference. Peel the paper backing off the cut portion.
IMPORTANT:
5. Before more atmospheric condensation can occur on the
outside of the pipe, roll the DMP-1 dampening material once
around the pipe, following the scribe marks that represent the
inside edge of the fixture, as shown in Figure 3-23 below.

6. Reinstall the fixture, and make sure the spacing is set
correctly. Loosely mount the transducers on top of the
dampening material, using the correct spacing.

Installing the Dampening Material, Transducers and Fixtures
The DMP-1 material will only adhere to the pipe
correctly if the pipe is completely dry. To adhere
properly, the material must also be at a
temperature above 50°F (10°C).
