above.
6.2.3 Pipe connection
●
During installation, make sure that no sealant gets into the pipeline.
Sealing agents such as hemp and putty are not permitted since they can
lead to soiling and thus to functional problems.
●
Connect the pipelines to the inlet and outlet points on the measuring
device. Always heed the respective manufacturer's instructions.
NOTICE
Pipelines must be fitted absolutely tension-free to the device connections.
Pipelines must be designed in such a way that no tension e.g. caused by
changes in length due to fluctuations in temperature can be transferred to
the device.
During installation, make sure that no sealant gets into the pipeline. Sealing
agents such as hemp and putty are not permitted since they can lead to
soiling and thus to functional problems.
●
After the system has been put into operation, check all connections for
air-tightness.
6.3 Assembly with further components and devices
NOTICE
The operator's and maintenance instructions of the respective manufac-
turers must be observed during assembly with further components and
devices respectively. It is the only way to ensure safe and problem-free
operation.
