5. Commissioning, operation
Ensure that the sealing faces of the vessel or float switch are clean and
do not show any mechanical damage.

5.2 Mounting
Observe the torque values of screws specified in pipefitting work.
■
In the selection of the mounting material (sealings, screws, washers
■
and nuts), take the process conditions into account. The suitability
of the sealing must be specified with regard to the medium and
its vapours. In addition, ensure it has corresponding corrosion
resistance.
Mount the float switch either via mounting thread or mounting
■
flange (not illustrated).
The guide tube should not be inclined more than a maximum of
■
30° to the vertical.
If the geometry of the float does not fit through the process
■
connection, the float must be removed before mounting.
- For this, before removal, mark
the position of the float stops
with a waterproof pen
- Mark the mounting position of
the floats (e.g. "Up")
- After the float switch has been
mounted, the float should be
re-attached within the inside of
the tank (pay attention to the
mounting position!).
- Float stops must then be
re-attached at the marked
points.
The number of floats and also
■
the position of the float stops are
dependent upon the dimension
and the number of switch points.
