Installation
Installation with thermowell
When a thermowell is used, a welding sock-
et with G½ or G¾ female thread (to t the
thermowell) must be used.
Î Seal the thermowell into the welding
socket. Insert the sensor and tighten it
with the clamping screw.
Note:
For temperature regulators with safe-
ty temperature limiter (TR/STL), install
the sensor of the limiter near the sen-
sor of the regulator.
4.2.1 Capillary tube
Carefully run the capillary tube without
bending or twisting it. Avoid locations with
considerable ambient temperature uctua-
tions along the entire length of the tube.
Note:
Do not damage or shorten the capil-
lary tube. Roll up any capillary tube
that is not used. The smallest permis-
sible bending radius is 50mm.
4.3 Strainer(lter)
Install the strainer upstream of the tempera-
ture regulator.
– The ow of direction must correspond
with the direction indicated by the arrow
on the body.
– The lter element must be installed to
hang downward.
Tip:
Remember to leave enough space to
remove the lter element for clean-
ing.
4.4 Additional components
We recommend installing a hand-operated
shut-off valve upstream of the strainer and
downstream of the regulator in each pipe to
be able to shut down the plant for cleaning
and maintenance, and when the plant is not
used for longer periods of time.
To check the adjusted set point, we recom-
mend installing a thermometer immersed in
the medium to be controlled near the sensor.
