Fitting Instructions

1. Cut the lead pipe.
2. Smooth it’s surface for about 50mm from the end.
3. Removing the minimum of lead and chamfer the end.
4. The ideal lead pipe size is shown underneath the coupling description overleaf (on header card).
5. It should be a free fit without excessive play.
6. Re-assemble the coupling.
7. THE PARTS MUST BE ASSEMBLED AS SHOWN IN THE DIAGRAM BELOW.
8. TechTip: To determine the outside diameter of the pipe, wind a length of cotton twice around the pipe without stretching it and then measure its length.
9. Divide this result by 44 and multiply this answer by 7.
10. This is then the diameter of the pipe.
11. Insert the lead pipe into the coupling body until it reaches the internal stop.
12. Hold the body with a suitable wrench and tighten the lead thrust nut fully.
13. Maximum torque necessary is 15lbf.ft.
14. The 15mm or 22mm copper tube end is a conventional compression fitting.
15. A seal should be achieved after one turn maximum or 10lbf.ft torque.
16. Do not overtighten as this could damage the nut.
17. Pressure test when complete and re-tighten coupling nuts.
18. The Gripper Ring (Number 3 In Diagram) has necessary sharp edges, TAKE CARE WHEN HANDLING THIS COMPONENT.
