Installing the PDJ Dampening Jacket
If the pipe temperature is over 150°F, you must use the PDJ pipe
dampening jacket with preapplied DM P-3. As the dampening
material dries out over several hours after installation, its
effectiveness increases. The jacket is available in standard pipe
sizes from 4 to 12 in. (100 to 300 mm).
1. Remove any insulation from the installation area, as we ll as
any loose paint, rust and high spots from the pipe.
2. Remove the backing paper from the inside of the pipe
dampening jacket (shown in Figure 3-33 below).

3. Install the jacket on the pipe as shown in Figure 3-34 below.
Tighten the clamping screws so that some fluid drips from the
bottom of the jacket.
