NOTE:
The following steps must be performed while the first
stage is still pressurized.
6
Let the first stage stand
pressurized for several
minutes. Check that the MP,
remains stable. If the MP rises
more than 5 psi (0.3 bar), it
indicates a leak. If the MP is
stable, close the valve, purge
the line, and pressurize once
again to perform the final
check and assembly.
