                                                             1. Mark the pipe
                                                               Mark the insertion depth on the pipe for (see table).
                                                               The mark must remain visible under heating and jointing.









                                                             2. Heat pipe & fitting
                                                               Push the pipe and the fitting straight into the heating
                                                               bushes. Pull out the pipe and fitting slowly and without
                                                               twisting once the heating time has elapsed.






                                                             3. Joint pipe & fitting
                                                               Push the pipe into the fitting so that the welding beads of
                                                               pipe and fitting touch together. During the jointing time,
                                                               small adjustment in angle and alignment can be made.
                                                               During the cooling time, any stress on the joint must be
                                                               avoided.







                                                             4. Fusion inspection
                                                               The outer fusion bead must be inspected. A double bead
                                                               must be uninterrupted all around the pipe circumference.
