Due to the high energy in the back, if it is blown out in the
event of a failure, there is a risk of physical injuries or damage
to property through the ejected back and the media that
would then escape.

After installation, open the vent valve (if available) or set from CLOSE
to OPEN. The version of the vent valve depends on
the model and can deviate from the illustration!
For outdoor applications, the selected installation
location has to be suitable for the specied ingress protection, so
that the pressure gauge is not exposed to impermissible weather
conditions.
In order to avoid any additional heating, the instruments must not be
exposed to direct solar irradiation while in operation!
To ensure that the pressure can be safely vented in the case of
failure, instruments with blow-out device or blow-out back must keep
a minimum distance of 20 mm from each object.
