24 Installation
Use the following bolt installation procedure:
1. Carbon steel bolts do not require lubrication. Stainless steel bolts are factory-coated with a
lubricant to ease installation. Do not apply any additional lubricant when installing either
type of bolt.
2. Finger-tighten the bolts.
3. Torque the bolts to the initial torque value using a crossing pattern. See Table 2-3 for initial
torque value.
4. Torque the bolts to the final torque value using the same crossing pattern. See Table 2-3 for
final torque value.
5. Verify that the flange bolts protrude through the sensor module before applying pressure.
