the point where the cut was made with the jacket stripping tool, using case not to damage the outer layer of primary / pipe. After this cut is made, the Vlylar should easily tear away, exposing the primary pipe Repeat steps #1 through 4 on both ends of all rum of pipe. Testing SecondaryJJacket After completing the above steps on all rums of pipe,you are ready to perform the initial air pressure test on the secondary containment jacket. Step#1: Install an air test boot at each end of all pip- ing runs. Tighten the band clamps on the air test boots until they are snug. If you wish to test all runs at one time,connect the air test boots with a jumper tube avail- able from APT. Step 2-Removing the secondary containment jacket. Once the jacket stripping tool is in place, make sure that it is not cocked and that the blades are lined up with the mark. Swing the handle around until it fits into the groove in the housing, and tighten the handle until the - tool is completely closed, driving the blades into the sec- ondary containment jacket. Rotate the tool 1800 to 't 360°one way,and then 1800 to 3600 the other way,until a complete cut through the secondary containment jack- Al'T Bl'T-100 By-Pass Tubes available to test all piping et is achieved. runs at one time.

After this cut has been made, grasp one side of the jacket and tear away. After the first piping run has been charged, disconnect the air test regulator and repeat the process for all piping runs. After each run has been charged, record the exact Step #9: Now you have exposed 5" of primary pipe t mo covered by a thin layer of clear Mylar.
