2.The new septum is placed in the top of the inlet base. Make sure that sealing surfaces at the top of the inlet and inside the retainer nut are clean (no particulate matter).
3.Replace the septum retainer nut, tightening it to finger•tightness(as tight as possible by hand without using any kind of tool). Do not overtighten; the retainer nut is spring•loadedto provide sufficient pressure for sealing.
