   - Using the EMIS controllers in the middle level of the S3 vault (see figure above), ensure that the ion gauge I225IG is turned off.   - Using the EMIS controllers in the middle level of the S3 vault (see figure above), ensure that the ion gauge I225IG is turned off.
   - Ensure that gate valves I246GV (between lower-dipole section and target area) and I215GV (between intermediate image area and the lower-dipole section) are closed.   - Ensure that gate valves I246GV (between lower-dipole section and target area) and I215GV (between intermediate image area and the lower-dipole section) are closed.

Locate the I226PG Pirani gauge and ensure that it reads rough-vacuum pressure (few militorr).
   - Slowly open the manual valve (see picture below) and verify that the pressure read in I226PG raises slowly.   - Slowly open the manual valve (see picture below) and verify that the pressure read in I226PG raises slowly.
