the measuring insert.
2.3 Installing the meter onto the monopipe adapter EAS

Prior to the installation of the meter, the measuring insert should be inspected to
ensure that no damage has been inflicted on the meter during transportation.
Accessories should be inspected for completeness (e.g. Pulse generator). Faulty
components should be replaced.

The measuring insert is delivered in special protective packaging. This should only
be removed shortly before installation.

Installation of the meter is possible horizontally or vertically (if over-run brake is applied,
only horizontal position with counter on top is allowed); the meter head can be rotated
in 90° steps. It should however, always be ensured that the axis of the roller counter is
horizontal (i.e. volume value can be read). The meter must not be installed upside
down.

Before mounting the meter onto the EAS, make sure that the pipeline has been
flushed and is clean. If not please refer to section 2.2 "Cleaning of the pipeline prior
to measuring insert installation".

The gas should be dry and free of dirt and dust. Particles may not be larger than
5Microns. Otherwise, we urgently recommend the installation of a dust-moisture trap.

In case of new systems, the temporary installation of a filter or cone screen (mesh
width: 0,5 mm) is recommended in order to protect the meter. The cone screen
should be removed after 4 weeks.

The O-rings mounted on the meter must be firmly seated and must not be damaged
during installation.

The meter is mounted to the EAS by tightening the cylinder screws is a crosswise
manner. Please keep to the recommended tightening torque:
Nominal Diameter DN 50 = 40 Nm
Nominal Diameter DN 80 = 65 Nm
Nominal Diameter DN 100 = 100 Nm
Only the ELGAS, s.r.o. delivered screws may be used for this purpose.
