a. Rotate the Gas selection valve of the GRCM Control Box to GAS 1.
b. Turn the Out A needle valve counterclockwise to open it and purge the
reaction vessels for one (1) minute.
c. Close the lower manifold drain valves of the Quest reactor.
d. Turn the Out A needle valve of the GRCM control box clockwise to CLOSED
