If you have a cooling tower assembly installed:
Remove the assembly by grasping it and turning counterclockwise. The
septum is underneath the cooling tower inside the spring. The spring and
septum may pop out of the inlet when you remove the cooling tower. Be

them from the inlet.

Remove the septum nut by grasping the knurling and turning counter-

may also pop out when you remove the septum nut. Be careful not to lose
it.
Insert the narrow wire (or a piece of capillary column) into the inlet
through the oven, and push the insert and spring (if they did not come out
previously) out through the top of the inlet.
