  7. All Items available as spare parts.

INSTRUCTIONS

Step 1

Cut the pipe squarely in the middle of the witness mark on the pipe using secateur type cutters. (Do not use a hacksaw). This is important so that when a joint is made, the pipe has penetrated to the full depth of the socket. For pipes that do not have a witness mark, use the Witness Mark Gauge available from your supplier. If the pipe is not witness marked and a gauge is not available, measure the depth of the socket and apply your own witness mark to the pipe. 16mm witness mark length = 24.5mm-20mm witness mark length = 28.00mm.

As with any “O” ring joint, the external surface of the product in contact with “O” ring will effect the joint performance. Check for imperfections before cutting.

IMPORTANT:
It is vital that there is no threat to the performance of the “O” ring. Check for scratches, sand, mud, etc on pipe or within fitting before assembly, as these conditions may affect the integrity of the system.

Step 2

Ensure the pipe has a square cut and has no rough edges or external damage eg. scratches that may damage the “O” ring. Although not essential, there are hand held chamfering tools available to create a small chamfer on the outside of the pipe.

Step 3

Fit a SUPPORT SLEEVE to inside of pipe, pushing fully home.

Step 4

Push the pipe into the fitting using a twisting motion until it reaches the pipe stop. To ensure that the pipe has fully penetrated to the full depth of the joint, check that the witness mark is just visible at the face of the Plastic Retaining Nut.

A JOINT IS NOT COMPLETE IF THE PIPE HAS NOT PENETRATED THE FULL DEPTH OF THE SOCKET.

Step 5

To ensure the joint is not stressed, use a bend support or clip.

Step 6

To line up fittings like tees or elbows, the fitting can be twisted on the pipe to face in the desired direction.

Ensure that a space of 15mm between joints is allowed so that the retaining ring can be unscrewed if necessary.

Test system as required in A.S.3500.
