5. Transport, packaging and storage
5.1 Transport
Check the instrument for any damage that may have been caused during transportation.
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 conditions at the place of storage:
■ Storage temperature: 0 ... 70 °C
■ Humidity: 35 ... 85 % relative humidity (no condensation)
Avoid exposure to the following factors:
■ Direct sunlight or proximity to hot objects
■ Mechanical vibration, mechanical shock (putting it down hard)
■ Soot, vapour, dust and corrosive gases
■ Potentially explosive environments, flammable atmospheres
WARNING!
Before storing the instrument (following operation), remove any residual media.
This is of particular importance if the medium is hazardous to health, e.g.
caustic, toxic, carcinogenic, radioactive, etc.
6. Commissioning, operation
The connection dimensions of the thermowell must match those of the counterpart on the
process side. Insert the thermowell into the process adapter without forcing or damaging it.
For sealing, choose appropriate seals.
For installation, the appropriate fastenings, such as screws and nuts, must be used; also
using the appropriate mounting torques and tools (e.g. open-ended spanner). The seals
installed must be checked regularly that they are functioning correctly.
The corresponding parts on the process side, the seals and the sealing rings are not
included in the scope of supply.
