Assembly of the pipe component

When installing the pipe components, observe the following
points:
• During installation, it is important to ensure that the flow
direction corresponds to the attached label.
• When welding the welding adapter, remember to observe
the relevant welding instructions. The amount of heat
introduced must be kept to an absolute minimum to
prevent warping of the mounting flange's sealing surface.
• In the case of flanged connections, flat gaskets must be
installed, which should be in perfect condition and
resistant to the measuring media.
• Before installing pipe components or sensors, check all
components and gaskets for damage.
• Pipe components must not be installed under tension,
otherwise the piping may exert impermissible forces on
the device.
• When assembling the flanged connections, use screws
that offer the required strength and dimensions.
• The screws must be tightened evenly and to the required
torque.
• Once the pipe components have been installed, the
insertion connection must be sealed by means of a blind
flange plus gasket or by closing a shut-off device (if
present).
