5 Installation
The work described in this section is only to
beperformedbypersonnelqualiedforthe
assignment accordingly.
5.1 Installation conditions
Work position
The work position for the regulator is the
front view onto all operating controls on the
regulator(includinganyadditionalttings)
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 the process medium. To ensure that the
regulator functions properly, proceed as fol-
lows:
Î Observe the inlet and outlet lengths (see
Table5-6).ContactSAMSONifthereg-
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 sus-
pension’ 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 water drainage is required.
Î Installtheregulatorallowingsufcient
space to remove the actuator and valve
or to perform service work on them.
Mounting position
To ensure that the regulator functions proper-
ly, proceed as follows:
Î Install the actuator housing with the set
point springs suspended downward in
horizontalpipelines(seeFig.5-1).
Î Makesurethedirectionofowmatches
the direction indicated by the arrow on
the body.
Î Contact SAMSON if the mounting posi-
tionisnotasspeciedabove.
Damage due to freezing.
Protect the regulator from icing up when con-
trolling media that can freeze. Remove the
regulator from the pipeline when the plant is
shut down if the regulator is not installed ar-
eas free from frost.
