1. Pipe Grooving While grooving, the pipe should be manually supported to ensure that the pipe cross section does not move away from the groove head. If it does happen, the groove will be askew and will not be able for coupling. For this reason, it is recommended to support the pipe by hand for 2-3 cycles. After that, start applying weight on the hydraulic lever while allowing the pipe to rotate for 2-3 cycles until achieving the required depth. |

| 1.4 When the grooving is finished, turn off the machine and lift up the hydraulic lever. Use a measuring tape to measure the depth of the groove in accordance with the pipe size. The groove depth can be deviated within 3 mm. Once achieving the required groove depth, secure the level of the hydraulic pump at the grooving machine. Caution: Please observe heat accumulation at the groove head during the grooving process. If the groove head is too hot, the plastic will be easily broken. Thus, the groove head should be rest until it cools down before the work is continued. |

| After the pipe is grooved, coupling should be done as follows: |
| 2.1 Apply Herme Seal 55 at the pipe cross section to prevent rust. | 2.2 Cap the end of the pipe with the grooved line gasket to prevent the pipe cross section to be in contact with water. | 2.3 Apply lubricant at the rubber seal because the pipe cross section may contain sharp points, causing scratches on the rubber seal, which reduces its life time. Lubrication will help prolong the life time of the rubber seal. |
 2.4 Put the lubricated rubber seal on the pipe, then start coupling. |
 2.5 Fit the pipe with the coupling and tighten the bolt. The completely installed pipe.
