HOW
TO USE YOUR 1. Verify the
source, destination, type, contents, and pressure of the line you
are about to tap. 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 1 Hot Tapping Machine ships ready to use, 2 strips of 100% pure graphite will need to be installed under the packing nut, around drive shaft at the back end of the machine. Install so the packing seams are on opposite sides. Then packing is installed as needed. 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). Packing strips are pre-cut to fit properly. 6. Now select the proper cutter and install the hexagon arbor of 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. 8. Now the XTC-1 hot tapping machine can be threaded onto the branch line ball valve by using the proper sized adapter found in the Easy TapperTM kit. Note: All threads off of main line and including adapter threads to the XTC-1 tapping machine should have thread sealing compound or Teflon tape applied to them. 9. A garden hose (or the like) can be hooked up to the side outlet ball valve on the side of the XTC-1 hot tapping machine. The side outlet valve may be opened during the tapping process, so that shavings can be removed through the hose to an approved receptacle. 10. A 1/2" electric or air powered drill can now be hooked up to the no-slip hexagon end of the drive shaft. Before drilling, verify that the cutter easily moves into position against the main line. Also, verify that the length of the drive shaft will be adequate to fully penetrate the wall of the main line. 11. You are now ready to drill into the main line. Start the drill momentarily to verify proper rotation (clockwise on the main). By applying a constant even pressure and rotating the drill at the recommended speed for the material that you are drilling into, you should be able to penetrate the wall of the main line with a minimal amount of effort. When the main line has been penetrated, the cutter can then be withdrawn back through the branch line 'full port' ball valve (it is recommended that all through the tapping process the side outlet ball valve remain open to flush shavings from the main and branch line). The branch line ball valve can now be closed. The tapping machine can now be disconnected from the branch line ball valve. The tapping process is now complete.
