5.1 Mounting preparation

Remove the protection caps of the process connections.
■
Ensure that the sealing faces of the vessel or glass level gauge are
■
clean and do not show any mechanical damage.
Check the connection dimensions (centre-to-centre distance) and the
■
alignment of the process connections on the vessel.
5.2 Mounting of models LGG-R, LGG-T, LGG-M
Mount the glass level gauge vertically on the vessel.
■
Observe the torque values of screws specified in pipefitting work.
■
Install the glass level gauge without stresses.
■
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.
For rotatable designs, the corresponding threaded connections must
■
be loosened by approx. 2 turns. Once the glass level gauge has been
aligned, tighten the threaded connection again to 25 Nm.
