2. Use this method to install the detector along with a protective plate to prevent
PVC pipe from being deformed or damaged when the bolts are tightened to the
specified torque.
Insert a protective plate between the outer side of the PVC flange and the detector
as shown in Figure 2-22. The protective plate protects the PVC pipe from
deformation or damage when it is secured to the specified torque. For the
appropriate torque, see Table 2-1 on page 2-12.
3. Use this method to install the detector using a low fastening torque and rubber
gaskets.
First, remove the grounding ring from the detector, then insert a rubber gasket
with a thickness of 0.5 to 1.0 mm. Then reinsert the grounding ring on top of the
rubber gasket.
Next, remove the PTFE gasket and insert a rubber gasket 3.0 to 4.0 mm thick to
replace it. Under these conditions, install the detector on the pipe as shown in
Figure 2-23. Tighten the bolts to the torque required to achieve a fluid seal for the
rubber gasket. In this case, the two kinds of rubber gaskets that are used should be
made of the same material. For the dimensions of the rubber gaskets, refer to
Table 2-3 and Table 2-4 on page 2-16.
