Step 5. Place the gasket into the gasket pocket with the gasket marking side in first.
Step 6. Rotate the Flange Adapter to align the bolt holes with the mating flange. Alternate when tightening nuts to bring bolt pads into metal to metal contact.
Step 7. Bring both the Flange Adapter and the mating flange together. Ensure proper bolt hole alignment. Slide a flange bolt through the bolt holes and hand-tighten the threaded nut on. Continue this procedure until all flange bolts have been inserted. Tighten the flange bolts and nuts evenly to the specified mating face bolt torque. Ensure the flange faces remain parallel and make contact around the full circumference of the flange face.
Note: To achieve proper flange joint connec- tions for the Figure 71 Flange Adapter (14 to 24 Inch), refer to the recommended flange mating bolts torque range listed in the Grooved Cou- plings section of this manual. Failure to use the manufacturer's power impact wrench set- tings and abide by manufacturer instructions may result in loss of warranty protection, invali- date listing certifications and/or cause personal injury or property damage.
Flange Adapters are not recommended for applications that incorporate tie rods for anchoring, or on standard fittings within 90° of
each other. Refer to Tech Data Sheet G150 (Figure 71 Flange Adapter) for additional information.
Flange Adapter Washers are required when the Flange Adapters are used against surfaces such as:
1. Rubber surfaces
2. Adapting to AWWA cast flanges
3. Rubber-faced wafer valves
4. Serrated flange surfaces
For additional information on Flange Adapter Washers, refer to the Grooved Couplings section of this manual.
