5 Installation
The work described in this section is only to
be performed by personnel appropriately
qualiedtocarryoutsuchtasks.
5.1 Installation conditions
Work position
The work position for the regulator is the
front view onto all operating controls on the
regulator(includinganyadditionalttings)
seen from the position of operating person-
nel.
Plant operators must ensure that, after instal-
lation of the device, the operating personnel
can perform all necessary work safely and
easily access the device from the work posi-
tion.
Pipeline routing
The inlet and outlet lengths vary depending
on several variables and process conditions
andareintendedasrecommendations.Con-
tactSAMSONifthelengthsaresignicantly
shorter than the recommended lengths.
To ensure that the regulator functions proper-
ly, proceed as follows:
Î Observe the inlet and outlet lengths (see
Table 5-1).ContactSAMSONifthereg-
ulator conditions or state of the medium
process deviate.
Î Install the regulator free of stress and
with the least amount of vibrations as
possible. Read information under
“Mounting position” and “Support or
suspension” in this section.
Î For media with a tendency to conden-
sate, install the pipeline with a slight
downward slope on both sides so that
the condensate can drain properly. If the
pipeline upstream and downstream of
the regulator run vertically upwards, an
automatic drainage is required.

space to remove the control thermostat
and valve or to perform service work on
them.
Mounting position
To ensure that the regulator functions proper-
ly, proceed as follows:
Î Standard mounting position: install the
control thermostat suspended downward
inhorizontalpipelines(seeFig.5-1 and
Fig.5-2).

Damage due to freezing.
Protect the regulator from icing up when con-
trolling media that can freeze. Unless the
regulator is installed in locations where no
frost occurs, remove the regulator from the
pipeline when the plant is shut down.
