5 Installation

The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.

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 fittings)
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
and are intended as recommendations. Con-
tact SAMSON if the lengths are significantly
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). 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
suspension" in this section.
EB 2111/2121/2123 EN
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.
Î Install the regulator allowing sufficient
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
in horizontal pipelines (see Fig. 5-1 and
Fig. 5-2).
Î Make sure the direction of flow matches
the direction indicated by the arrow on
the body.
Î Contact SAMSON if the mounting posi-
tion is not as specified above.
NOTICE
!
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.
