GB
The system operator is responsible for selecting the thermometer or thermowell, and for the
selection of their materials, so as to guarantee their safe operation within the system or machine.
When preparing a quote, WIKA can only give recommendations which are based on our
experience in similar applications.
The thermometer has been designed and built solely for the intended use described here and
may only be used accordingly.
The technical specifications contained in these operating instructions must be observed.
Improper handling or operation of the instrument outside of its technical specifications requires
the instrument to be shut down immediately and inspected by an authorised WIKA service
engineer.
If the instrument is transported from a cold into a warm environment, the formation of
condensation may result in the instrument malfunctioning. Before putting it back into operation,
wait for the instrument temperature and the room temperature to equalise.
The manufacturer shall not be liable for claims of any type based on operation contrary to the
intended use.
