Additional Information For The Vh; Material Specifications Of Wetted Components - SIKA VH Notice D'utilisation

VH... / VK...
If the medium which is to be monitored is very hot, the level switch will also become ex-
tremely hot. In this case, neither touch the level switch nor place any heat-sensitive ob-
jects in its vicinity.
Protect the level switch against external magnetic fields in the immediate vicinity, since
these can impair instrument functioning.
The technical data of special versions (customised versions) may differ from the data in
these instructions. Please observe the information specified on the type plate.
WARNING! Danger high voltages!
De-energise the system before connecting the wires of the connecting cable.
It is prohibited to remove or make type plates or any other information attached to the
equipment indecipherable, otherwise all warranties and the responsibility of the manu-
facturer no longer apply.
2.3 Additional information for the VH...X level switch
The level switch should only be used for media with a minimum ignition temperature of
>135 °C and ignition energy of >60 µJ.
When installing and before starting-up, it is to be guaranteed that the mechanical process
connections are technically tight.
Always consider the sealing of the screwing elements for the zone allocation. Depending
on the operating conditions, it may be necessary to regularly check the sealing of the
screwing elements.
