Installation Procedure

1. Make sure that the insulation kit you received is undamaged and contains the materials and parts you requested.
2. Check that the flange faces and fully threaded bolts are clean and lubricated.
3. Install gaskets by carefully aligning over bore so gasket and bolts center.
4. Alignment pins 3/32" larger than bolts should be used in two opposing bolt holes to assure proper alignment of flanges.
5. Place sleeves in open bolt holes. Do not force sleeve or damage may result.
6. Place fully threaded bolt in insulating sleeve with isulating washer next to flange followed by the steel backup washer and nut.
7. Tighten opposite bolts to 30% of the required torque.
8. Remove alignment pins and repeat process.
9. Using a bolting diagram, tighten all bolts to 50% of their final torque value. Repeat torquing process until you have reached 100% of the required torque.
10. Flange electrical shortout may occur if foreign matter is allowed to accumulate between the flange surfaces.
