Measure the pipe to the correct length and using a secateur type tool, cut the pipe squarely and remove any burrs. If the pipe is witness marked, cut squarely in the centre of the mark. The end of the pipe may need to be freshly cut to ensure smooth passage for the fitting. Do not use a hacksaw.
The pipe is pushed over the barbed fitting and at the same time under the crimp ring. The fit sould be firm. If the joint feels sloppy or hard to insert, check pipe and fittings. Do not use lubricants.
Centralise the tool jaws over the crimp ring at 90deg. to the joint. Close the tool completely to compress the crimp ring. The tool will click at final compression.
Check with the gauge supplied by sliding the opening of the gauge over the compressed ring. If it passes over the ring easily, the joint has been completed satisfactorily. If the gauge does not pass over the ring, the joint is under crimped. The tool should then be adjusted. (See adjustment instructions). Do not double crimp.
Pressure test the system in accordance with A.S.3500 parts 1 & 4 or in accordance with local requirements. Cut out any defective joints. Fittings can be re-used by cutting off the compressed ring and replacing with a new ring. Ensure that no damage is done to the brass barbs when cutting off the ring or removing the pipe.
