For additional set up illustrations, see Appendix B or contact your distributor / MCS representative. Remember to consider the ancillary steps like purging / venting the area to be worked on and back pressuring stoppers for removal. The features of the MCS7-2PVC offer options to make these processes efficient. Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com... - Page 5 8) Keep by-pass / vent ports on towers #2 and #3 open to atmosphere during work to keep gas away from the work area. Follow company procedures for venting and purging gas. 9) This set up can easily be used on both single feed and dual feed systems. Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com...
- Page 6 4) Use system pressure gauge on tower #1, #2, #3, or #4 to determine if stoppers are equalized. 5) When pressure is equalized, deflate stoppers #1 and #4. Retract all stoppers. 6) Remove tools and install completion plugs. Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com...

Make sure the threads are clean, the o-ring is in place, and the device operates freely. Visually inspect the drilling dome and verify the o-ring is in place. Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com... - Page 14 Grease the rod with silicone grease for a smooth installation. Then, install the drilling rod through the hot tapping device and dome. Install the cutter onto the drilling rod and tighten the cutter. Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com...
- Page 15 When doing this, make certain the valve doesn’t inadvertently turn. Position feed tube so it is flush with the bottom thread. Verify drilling dome bleed valve is closed. Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com...
- Page 16 Place the drilling rod handle through the top of the drilling rod. Use the handle to turn the drilling rod clockwise (down) to cut the pipe. Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com...

Page 19: Stopping Operation
NEVER pre-bend the MDS Stopper on the frame!!! This can damage the frame and it will not help as the internal frame is rigid. Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com... - Page 20 (This is the silver connection.) With the valve open, pull a vacuum to -15 psi on the stopper to make it as compact as possible. Close the valve after evacuation. Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com...
- Page 21 After the stopper stabilizes, wait 10 minutes to make certain the same pressure is maintained within the MDS Stopper. NOTE: Do not inflate the stopper outside of a pipe as it can damage the stopper. Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com...
- Page 22 Lock the gauge rod by operating the black thumb screw. Using the same Kleiss silicon spray you used on the stopper, lightly spray the open end of the chute. Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com...
- Page 23 Position the stopping tower so stopper will be inserted into the correct position. (The stopper deploys out the opposite side of which the by-pass / vent port is attached.) When doing this, make certain the valve doesn’t inadvertently turn. stopper Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com...
- Page 24 Unlock the orange chute lock and lower the chute into the pipeline. Lock the chute assembly at this position. (The chute is now in the correct position inside the pipeline and you can commence inserting the stopper into the pipeline.) Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com...
- Page 25 Allow the stopper to stabilize inside the pipeline for at least 10 minutes. Verify inflation pressure and system pressure remains stable. You may now start your work on the pipeline. NOTE: Continue to monitor gauges on stopping towers. Kleiss MCS7-2PVC System Manual www.MainlineControlSystems.com...
