5. Transport, packaging and storage

5.1 Transport

Check the instrument for any damage that may have been caused by transport. Obvious
damage must be reported immediately.

5.2 Packaging

Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in
installation site, sending for repair).

5.3 Storage

Permissible storage temperature
-20 ... +70 °C

6. Commissioning, operation

6.1 Mechanical connection

In accordance with the general technical regulations for pressure gauges (e.g. EN 837-2
"Selection and installation recommendations for pressure gauges").
Instruments must be grounded via the process connection.
This is why electrically conductive sealing should be used at the process connection.
Alternatively, take other measures for grounding. When screwing the instruments in, the force
required for sealing must not be applied through the case, but only through the spanner flats
provided for this purpose, and using a suitable tool.
For parallel threads, use flat gaskets, lens-type sealing rings or WIKA profile sealings at the
sealing face . With tapered threads (e.g. NPT threads), sealing is made in the threads ,
using a suitable sealing material (EN 837-2).
