3.3 Starting fusion process
W
ARNING!
If there is a malfunction in the fusion process hot
molten PE may be expelled on rare occasions.
Therefore:
Maintain a safety distance of at least 1 m from
the fusion area during fusion! Do not connect
any additional equipment during fusion.
The fusion process can be cancelled at any time by
pressing the STOP button. When the fused area has
cooled down (and the source of the fault eliminated
where necessary) the fusion process can be repea-
ted (depending on the fitting manufacturer, please
observe operating instructions by the appropriate
fitting manufacturer).
Operating steps:
1. Display shows “PIPE PREPARED?”, confirm if
correct.
2. Press the START button to start the fusion
process. Now an automatic check of the ambient
temperature and resistance check of the con-
nected fitting follow. Fusion starts. The display
will tell you the duration of the fusion (it will show
total time of fusion and count it up in seconds till
the fusion ends).
3. Display “END OF FUSION” means that the fusion
process has been completed and the unit is ready
for the next fusion. Displays “t” and “tc:” show
reference and actual fusion time and must be
identical.
4. Mark fusion parameters on pipe/fitting. This will
make sure no second fusion is accidentally
carried out.
