In principle, the VTY can be installed at any point in the pipeline.
Straight pipe sections are preferable.
The installation can be carried out in horizontal as well as vertical
pipelines.
The flow sensor is exclusively for use in complete
filled cables.
You must absolutely avoid a free outlet.
The arrow on the flow sensor shows the only possible
flow direction.
!! must be resisted at all costs !!
CAUTION! Material damage!
Observe maximum torque. When tightening the union nut on the turbine body of
the unit, hold against it!
The VTY can be damaged if not held against it.
Tighten the two union nuts, holding them against the turbine body of the unit with
a spanner (SW19 / SW30).
