5. Insert the diaphragm into the cell cap so the gap clears the thermocouple.
6. Insert the other internal retaining ring into the groove above the
diaphragm so the gap clears the thermocouple as shown below.
On a High Pressure SGSM Cap, place the metal seal
ring on the external portion of the cell cap with the narrow
end pointed toward the threads. The seal ring should not
need to be removed from the top cell cap. If it must be
replaced, the metal seal ring must be reinstalled in the
same orientation.
7. Place an o-ring on the cell cap above the metal seal ring.
8. Install the external retaining ring above the o-ring.
On a Low Pressure SGSM Cap, only the o-ring (#123-011) is required
externally.
