The technical specifications and the Maintenance section, as well as the spare
parts lists and spare parts drawings in the appendix, describe all the gas pressure
regulator versions and all the models corresponding to the standard for this de-
vice type. Special-purpose versions are identified with "SO" in the inspection cer-
tificate, which is included with the gas pressure regulator.
However, other versions and models will be covered specifically as well when there
are important differences that need to be pointed out.
If you have trouble understanding the information in this documentation, contact
the manufacturer without fail before starting any work on the device.
Illegible information on the device poses a risk of injury due to resulting erro-
neous operation, use, or installation.
Labels, as well as inscriptions and stamping on the device, can eventually be-
come soiled or otherwise unrecognizable to such an extent that users will not be
warned effectively of hazards and may be unable to follow required operating in-
structions. This will pose a risk of injury.
Make sure to always keep all relevant labels in good condition so that they will
be easily legible.
Immediately replace damaged and missing labels.

For the location of the nameplates, as well as a detailed list of the information on
them and what it means, please refer to:
Identifying the device (see page 10)
Small labels must be used to color-code and explicitly name the gas pressure reg-
ulator's connection lines (measuring lines and operating lines) based on what the
lines are intended for and their minimum nominal size.
