2. Safety information
Read this guide carefully and follow
the instructions.
Before installation, check the suitability
of the thermometer for your application.
This applies to the measuring range, the
immersion tube design, the immersion
tube material, the sealing material and the
installation conditions. With this inspection,
the risk is transferred to you and our
warranty expires.
Installation, operation and maintenan-
ce must be carried out by fully qualified

Observe the applicable regulations on
accident prevention and safety at work.
Never use the thermometer as a
handle or stepping surface. Do not subject
it to any other mechanical stresses.
Only use the thermometer if it is in
perfect condition.
CAUTION! High temperature!
The casing can become hot during
operation.
Never touch the hot thermometer.

Only use suitable sealing materials.
Use a sealing material that is suitable
for the temperature range and resis-
tant to the medium to be measured.
Before mounting:
Before starting work, check that the requi-

met:
The plant is switched off and
ˆ
depressurised.
The plant has cooled down to
ˆ
ambient temperature.
A threaded socket is available at a
ˆ
suitable location in the plant.
A suitable sealing material is used.
