ARPOL FIXL FITTING INSTRUCTIONS INFORMATION INCLUDED ON THE LABEL: ARPOL reference. Outside diameter of the pipes to be joined. Working Pressure (bar) Test Pressure = 1,5 x working pressure Torque value (N/m) STEPS TO ADEQUATELY FIT ARPOL FIXL COUPLING: 1. Clean pipe ends and eliminate any irregularity.. Mark both pipe ends syetrically at a distance from the edge equivalent to half of the coupling width.. Slide the coupling over one pipe end. 4. Bring the other pipe end to a facing position. Make sure the alignment limits as well as angular deflection, etc., are respected and that both pipe ends are correctly held. 5. Place the coupling between the marks and check that the inner steel bridge is correctly placed under the lock. 6. Tighten screws: DO NOT TURN THE COUPLING WHEN SCREWS ARE BEEING TIGHTENED 6.1. Start the tightening of screws using a click wrench with a nozzle. screws lock: tighten both screws by alternative short movements until you nearly reach the end, but do not exceed the torque value. screws lock: First tighten the central screw up to 10. Then tighten exterior screws positioning them at the same level as the central screw. Keep tightening the three screws by alternative short movements until you nearly reach the end, but do not exceed the torque value. 6.. Finish the tightening with a dynamometric wrench with sound signal. Adjust the wrench to the torque value printed on the coupling label. Keep tightening screws alternatively with the dynamometric wrench until you can hear the click sound at the beginning of the tightening. 7. If necessary, you may hydraulically test the coupling up to 1,5 the working pressure (see label). 11
