3.2 Intended use
The transducer may only be used in such applications as are within its technical performance limits, in particular with
regard to its material resistance limit, leakage rate limits and permissible temperature and pressure limits.
It is the sole responsibility of the manufacturer or operator of a machine or plant to ensure the suitability of the
transducer, and its media resistance, within the application through proper choice of materials and maintenance cycles.

Do not dispose of with household waste. Ensure a proper disposal in accordance with national regula-
tions.
4. Mounting
4.1 Mechanical mounting
Requirements for the mounting point
Only use the transducer if it is in perfect condition with respect to safety.
Prior to commissioning, the transducer must be subjected to a visual inspection.
Obvious damage must be reported immediately.
WARNING!
Damage to property due to improper welding
Improper welding can lead to a short-circuit and damage to electrical equipment.
Before arc-welding, ensure the transducer is not connected to any other devices.
Disconnect all electrical connections to the transducer.
Ensure that the supply lines from the stranded wire do not come into contact with metal surfaces.

7.2 Return
WARNING!
Physical injuries and damage to property and the environment through residual media
Residual media in the dismounted instrument can result in a risk to persons, the environment and
equipment.
In case of hazardous substances, enclose the material safety data sheet for the corresponding
medium.
Strictly observe the following when shipping the instrument:
All instruments delivered to WIKA must be free from any kind of hazardous substances (acids, bases, solutions, etc.)
and must therefore be cleaned before being returned.
When returning the instrument, use the original packaging or a suitable transport packaging.
