Releasing
Do not move the machine carriages!
1. Reduce the fusion force to 0 via the hand wheel, therefore secure the
position of the hand wheel with the left hand, open the locking screw and
turn carefully the wheel counterclockwise.
2. Open the clamps and remove the fused pipes/fittings.
All fusion joints must have cooled completely before the pressure test is
performed. This is generally the case approx. 1 hour after the last fusion
operation.
8.1.4 Visual check of welding bead
Immediately after removing the welded pipes/fittings visually check the part for
correct definitive double bead and the k-value.
Attention
CAUTION
Even double
k > 0
