1. Check that the support liner and wedges are suitable for pipe OD and wall thickness.
2. Measure bore of pipe and select correct wedge from the set of 4 supplied (See Table 7 for PE).
3. Insert the liner into the bore of the pipe until the shoulder tabs butt against the pipe end.
4. Fit the appropriate jacking stud through the pad eyes in the liner (Fig 2).
5. Using the nuts on the studs, expand the liner until it contacts the pipe bore.
6. Insert the appropriate wedge into the channel of the liner.
7. Tap wedge until liner is fully expanded against pipe bore.(Fig 3)
8. Clip the wedge retention clips in the channel holes closest to the end of the wedge to prevent wedge sliding out.

10. Slacken off the nuts on the jacking studs and remove jacking studs and nuts.
WARNING: Damage to the wedge or liner coating will result into rusting of the product; utmost care must be
taken when inserting the wedges in the liners to avoid damaging the coating.
