HOW
TO USE YOUR
1. Verify the source, destination, type, contents, and pressure of the line you are about to tap. Note: Maximum tapping pressure for the Model #XTC 5.5Z is 1470 P.S.I.G. at 100 degrees F. 2. A Tapping saddle of proper size can then be tightened on to the main line. (In some cases a thread-o-let or malleable iron nipple can be arc welded to the main line). 3. A short nipple is then threaded into the tapping saddle. 4. A "full port" ball valve is then threaded onto the short nipple. Note: Gate valves are not recommended in this case, because shavings from the drilling process tend to collect in the gate chamber, preventing the gate from closing all the way. 5. The XTC 5.5Z Hot Tapping Machine will be ready to use, after placing 2 strips of pure graphite in the packaging box, from the package provided with the kit. Grease has been factory installed in the bearing box. Additional packing can be added at any time (even during the tapping process, simply by withdrawing the drive shaft and cutter back out of the branch line valve and then closing the branch line valve while packing is installed). 6. Now select the proper cutter and install the hexagon arbor for the cutter into the hexagon receiver end of the drive shaft. Note: the proper cutter size will generally be 1/8” smaller than the "full port" size of the branch line ball valve you are tapping through. The pilot bit can now be installed in the arbor to lead the cutter. The end of the pilot bit should be positioned to penetrate the wall thickness of the main line before the cutter engages the wall of the main line. The cutter and the pilot should now be tightened securely to the drive shaft. 7. At this point it is a good idea to verify that the cutter will slip through the branch line ‘full port’ ball valve without causing damage.
