Note
In the next step, if mounting the wafer body on a displacer cage and a flange adaptor is required, install the flange adaptor instead
of the blind flange.
5. Refer to figure 11. Place a second seal on top of the wafer body. Place a blind flange on the wafer body so that the
holes in the blind flange align with the holes in the connecting flange.
6. Refer to figure 12. Secure the wafer body between the blind flange and connecting flange by inserting the
remaining studs and nuts. Tighten the nuts just enough to hold the wafer body in place.
7. Remove the nut from the stud that was used in step 2. Reinsert the stud so it passes through the holes in the blind
flange and connecting flange. Thread the nut back onto the stud.
8. Tighten all nuts in a crisscross fashion to the torque recommended in tables 2 or 3.
