2.1 Qualified personnel

The personnel who are charged for the installation, operation and maintenance of the
VH... / VK... must hold a relevant qualification. This can be based on training or relevant
tuition.
The personnel must be aware of this operating manual and have access to it at all times.
The electrical connection should only be carried out by a fully qualified electrician.

2.2 Special safety instructions

In all work, the existing national regulations for accident prevention and safety in the
workplace must be complied with. Any internal regulations of the operator must also be
complied with, even if these are not mentioned in this manual.
To avoid damages to the level switch and the monitored system, only use the SIKA level
switch to monitor the filling level of liquids.
Always follow and adhere to the level switch installation instructions.
Prior to level switch installation, ensure that the materials of the level switch are chemi-
cally and mechanically resistant to the media which is to be monitored and to all external
factors.
Ensure that the medium is free from magnetic particles and that the minimum density
value exists ( § 9 "Technical data").
Suitable measures should be taken to prevent the medium from freezing.
If the level switch is to be used in ambient temperatures of <4 °C, do not carry out any op-
eration beforehand with pure water, e.g. a test run. Residual water in the level switch can
result in frost damage.
Due to the material resistance, no lubricants, oils etc. should be used when installing the
VK.. level switch.
Ensure that the maximum specified operating pressure is not exceeded.
Never remove a level switch or the upper parts of a level switch from a pressurised sys-
tem.
