2. Use this method to install the detector using a protective plate to prevent the PVC pipe
from being deformed or damaged when the bolts are tightened with the specified torque.
Install the protective plate between the outer side of the PVC flange and the detector,
as shown in Fig. 2-15. The protective plate protects the PVC pipe from deformation or
damage when secured at the specified torque. The torque level is unrelated to the pipe or
grounding ring material. See Table. 2-1 on page 2-8 for the appropriate torque.

3. Use this method to install the detector using a low fastening torque and rubber gaskets.
Remove the grounding ring from the detector, insert a rubber gasket 0.5 to 1.0 mm thick,
then reinsert the grounding ring on top of the rubber gasket. With the rubber gasket in the
position shown in Fig. 2-16, attach the detector to the pipe. Fasten the bolts with a torque
that provides a leakproof joint. In this case, use the two kinds of rubber gaskets made of the
same material.
