In the case where installing with the prescribed tightening torque gives rise to a
threat of deformation of, or damage to, the PVC pipe (protective fixture used)
Provide a protective fixture that can be attached to the outside of the PVC flange
and will not deform or damage the pipe when the prescribed tightening torque is
applied. Attach the protective fixture to the PVC flange and install the detector as
shown below. The tightening torque should conform to Table 2-1 on page 2-9
irrespective of the gasket material.

In the case of installing with a small tightening torque (rubber gasket used)
Remove the grounding rings from the sensor and insert a rubber gasket 0.5 to 1
mm thick between the lining and grounding ring. Then, fix the grounding ring
again.
In this condition, install the sensor to the pipe using the provided rubber gaskets
(3 to 4 mm thick). The tightening torque to be applied is the torque necessary for
the liquid seal of the rubber gasket. In this case, use the two kinds of gaskets of
the same material.
