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-3HPSS is 5000P.S.I.G. at 100 degrees F.
    
2. Verify the line size of the the line to be tapped. The XTC-3HPSS is designed to be used on lines with outside diameters between 2 3/8” and 4 1/2”.
    
3. Inspect the tapping machine to insure sealing components are in place at tapping end of machine and in packing box section near back of machine. Add packing only while machine has no internal pressure. To add packing remove the two side bolts on outside of machine. Remove the two flathead screws holding packing box cap in place (through slots in side of machine). Remove the Five flat head screws mid machine. Slide back section away from front section, exposing packing box. Move back section away only far enough to facilitate adding packing strips. Cutter shaft should still be in place through packing box. Add one or two strips leaving seams on opposite sides. Start by pressing open ends together then press remainder of strip onto box. Move packing pressure block forward into packing box, then reassemble machine by reinstalling all previously removed components. Snug down external packing box screws, to seal yet allowing slightly restricted rotation of cutter shaft. tighten as needed but do not overtighten.
    
4. The tapping seal bolt (1 3/4” hex) should be removed every 4th tap to remove shavings. Use brass (only) wire brush to clean components and threads. Inspect Viton O Rings and replace as needed
    
5. The machine is placed around the line to be tapped. Place "V" shaped pressure block against wall of pipe. Turn tightening bolt until the tapping seal contacts wall of pipe. Make sure tapping seal is centered on line.
    
6. The pressure block bolt should now be tightened by use of a torque wrench.
   The proper torque for safe use at the maximum 5000 P.S.I. main line pressure is 12.5 foot pounds. Tighten as high as 15 foot pounds. Do not overtighten.
    
7. The sealing integrity of the machine and the connection to the pipeline can be tested if desired by pressurizing the apparatus through the side outlet on the machine with an inert gas, and then soap testing connections and moving parts.
    
8. Now the XTC 1.5Z tapping machine can be threaded onto the branch line ball valve by using the proper sized adapter found in the “Easy Tapper”™ kit. Note: All threads off of main line and including adapter threads to the XTC 1.5Z tapping machine should have thread sealing compound or Teflon tape applied to them.
    
9. Rotate the adjustable spindle at the back of the machine to advance the cutter forward until reaching the wall of the main line. Start the drill motor and advance the cutter by rotating the spindle. Continue until through the wall of the pipeline.
    
10. With the machine in place, test for pressure and vent safely as needed to atmosphere or receptacle.
     
11. When finished, disconnect machine.
     
12. A 3/16” hole will be left in wall of pipeline. Seal by proper methods if pipeline is to be repressurized.
    
    

Stainless Steel Tapping Procedures

Use a 1/4" Cobalt Pilot Bit. Position within the Bimetal Hole Saw to extend completely through the wall of the pipe before the teeth of the hole saw contact the wall of the pipe. As the Cobalt Pilot Bit penetrates the wall of the main line, fluid will rush into the tapping machine body and will act as a coolant for the Bimetal Hole Saw.
