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
torque value.
4. Torque the bolts to the final torque value using the same crossing pattern. See
final torque value.
5. Verify that the flange bolts protrude through the sensor module before applying pressure.
