Replace the Gasket each time the Launch Cylinders are assembled.
Verify that the Valves are oriented at the bottom for draining process fluid when the job is complete.
Close each Valve.
Insert the Gasket between the Flanges on each Launch Cylinder.
Bolt each Launch Cylinder section together. Use a star pattern for balanced torque. Complete the pattern three times 30%,
70%, 100% to the torqueing sequence. See Torque Figures on page 5.
