6. Installation / Connection / Commissioning

The meter may only be installed by authorized trained personnel.
The meter must be installed in accordance with the regulations in force. Compliance with the
directives of the gas supply company or, in the case of Germany, of the DVGW Code of Practice
G600 (DVGW-TRGI), in the version currently valid in each case, is required for the installation of
gas meters.
Before installation please ensure:
– that the protective caps and/or plastic sheeting is or are removed,
– that the meter and accessories have been inspected for transport damage,
– that the accessories have been checked for completeness and
– that you only use seals made from approved materials.
Then install the meter

– in the driest possible environment and where it may be easily read (the meter must not come
into contact with surrounding masonry),
– only in flow direction (as marked by an arrow on the meter housing),
– free of mechanical stress, and make sure when inserting the seals that the seal faces are
clean and undamaged, and that the seals are concentrically aligned and do not protrude into
the pipe cross-section. For the compression of seals and the resulting tightening torques
for the connection elements, the seal or the screw manufacturers' speci fications must be
observed.
– Only use the seals once!
