3.1.1. Requirements for pipelines

• Correctly dimensioned gaskets
• Correctly aligned flanges and gaskets
• Differences in pipe diameters at joints should be avoided or, if present, should not exceed 1 mm. For more information, see the
ISO 14511 standard.
• Clean, properly installed pipes.

3.1.2. Requirements for the inlet/outlet pipe section

Depressurise the system before carrying out any set up or maintenance work. Such work must be
carried out by authorised skilled technical personnel (see "Safety instructions" on Page 5).
Above 10 bar, use the high-pressure safety device for safe installation and removal.
Tighten the adapter sleeve using a torque of 20–30 N·m (spanner size 27).
Use only pressure-resistant installation materials and suitable tools that are in proper working order.
Before pressurising the system, check all device parts and repair them as necessary. Open valves
slowly to prevent pressure blow-outs during operation.

Deviating measurements
The above values are required minimum values (presented in a
simplified form). If the recommended settling sections cannot
be implemented, the deviations in measurements made may
become more frequent or very frequent.
