▷ If the meter is stored outdoors, protect the site
against rain.
▷ If the drive area (magnetic coupling) is protected
against the ingress of moisture by an index, then
the meter is also suitable for outdoor installation.
Remove protective caps.
▷ Installation in the vertical position: connectors
must be pointing upwards.
▷ Note direction of flow (arrow).
▷ After installation, the completed gas meter must
not be in contact with masonry or other parts.
▷ Ensure that there is sufficient installation space.
▷ The seal faces on the screw unions must be
clean and damage-free.
▷ Ensure that the seal is correctly seated.
▷ For the compression of seals and the resulting
tightening torques for the screw unions, the seal
manufacturers' specifications must be observed.
Tightening torques for the recommended flat
seals in conjunction with screw connectors
