Example II – Stopper Retraction Sequence: Stoppers Positioned Away From Work Area

NOTE: Always equalize pressure on both sides of the stopper before deflation or removal.

1) 

Deflate stopper #2.

2)  Back pressure stopper #4 through the system pressure ports in towers #3 and #4.

3)  Deflate stopper #4.

4)  Equalize pressure on stoppers #1 and #3 through the by-pass / vent port between towers #3 and #4.

5)  Use the by-pass / vent port in tower #1 or #2 to purge air from repaired area.

6) 

Use system pressure gauge on tower #1 or #2 to determine stoppers are equalized.

7)  Deflate and remove stoppers.

8) 

Remove tools and install completion plugs.

 

NOTE: For additional set up illustrations, see Appendix B.
