2.4.1: Determining the fastening torque
The following table shows the fastening torque for each pipe bore.
CAUTION
The correct fastening torque must be used to prevent leakage. To avoid damage to
the detector, do not exceed the listed fastening torque.

2.4.2:
Selecting the flange shape
The flanges used for installation should maximize the area of contact with the gasket.
(The liquid could leak because of the
small area of contact with the gasket.)
