3.2 Mechanical installation
WARNING
Leakage or rupture due to improper mechanical installation.
Risk of severe injury!
Risk of substantial property damage!
• Never attempt to overcome misalignments (lateral, angular, longitudinal,
torsional) using force.
• Make sure the piping is flexible enough; if not, use compensators.
• Consider the effects of thermal contraction and expansion.
WARNING
Leakage or rupture due to misuse of the installation material.
Risk of severe injury!
Risk of substantial property damage!
• With regard to mechanical strength, use the prescribed dimensions for
bolts, screws and nuts.
• Use the full number of bolts, screws and nuts.
• Observe the prescribed thread lubrication (grease or dry!).
• Tighten the bolts and nuts in the proper sequence to the specified
torque.
3.2.1. Isolation
NOTICE
In medium temperatures over 85°C the electrical unit must not be isolated. Here
the isolation has to be limited to the measuring pipe.
Hazard of malfunctions, damages or defects of the device!
• Clarify in advance if the medium temperate exceeds the limit of 85°C.
• In case no information is available for the medium temperature, the
electrical unit must not be isolated.
