Introduction
The installation method described in this section corresponds to the following combination
of pipe and grounding ring materials. For the installation method corresponding to any other
combination, refer to the table on page 2-13.
Pipe material: PVC
Grounding ring material: Other than SUS material
Required accessories
The following parts are required:

Through-bolts and nuts

Centering guide bushings

Gaskets: No gaskets are necessary due to the provision of a PTFE gasket. When
using a rubber gasket, gaskets of the same material and of two thicknesses,
0.5 to 1.0 mm and 3.0 to 4.0 mm, are required. See Table. 2-3 and Table
2-4on page 2-21 for the appropriate dimensions.

Protective plate: A protective plate is required if tightening the bolts to the specified torque
may deform or damage the PVC pipe. Use stainless steel or similar hard
metal 1 mm thick or over. For the shape, see Fig. 2-18.
Installation procedure
The installation procedure varies with such conditions as the fastening torque and the need for
a protective plate. Choose one of the following three methods as applicable.
