Type 2430 Control Thermostat measured in
water.
Capillary tube
Carefully run the capillary tube without
bending or twisting it. Avoid locations with
considerable ambient temperature fluctua-
tions along the entire length of the tube.
Note
Do not damage or shorten the capillary
tube. Roll up any capillary tube that is not
used. The smallest permissible bending radi-
us is 50 mm.
Support and suspension
Note
The plant engineering company is responsi-
ble for selecting and implementing a suitable
support or suspension of the installed regula-
tor and the pipeline.
Depending on the regulator version and
mounting position, the regulator and pipe-
line must be supported or suspended.
NOTICE
!
Do not attach supports directly to the regula-
tor.

5.2 Preparation for installation
Before mounting, make sure the following
conditions are met:
− The regulator is clean.
− The regulator is not damaged.
− Install a strainer upstream of the regula-
tor in the flow pipe.
− The regulator data on the nameplate
(type designation, valve size, material,
pressure rating and temperature range)
match the plant conditions (size and
pressure rating of the pipeline, medium
temperature etc.). See the 'Markings on
the device' section for nameplate details.
− The requested or required additional fit-
tings have been installed or prepared as
necessary before installing the valve and
control thermostat (see the 'Design and
principle of operation' section).
Proceed as follows:
Î Lay out the necessary material and tools
to have them ready during installation
work.
Î Flush the pipeline before installing the
regulator.
The plant operator is responsible for
cleaning the pipelines in the plant.
Î Check any mounted thermometers to
make sure they function properly.
Note
The plant operator is responsible for clean-
ing the pipelines in the plant.
