To maximize the time between repairs to the module, it is
recommended to overhaul all three analytical valves and the sample
shut-off valve at one time, rather than repairing only a single valve
when it is suspect.
Perform this procedure in a clean environment. When removing the
components from the valve, place them onto a clean work surface to
avoid contaminating the valve components.
This procedure assumes that you have removed the analytical
module from the GC.
