Note: If the immersion well is used, ll the well with special grease to improve response performance of the temperature sensor.
(Ex. For the stainless steel immersion well, response performance will be improved by approx. 15 %.)
For the special grease, the silicon grease, G-30M (Shin-Etsu Chemical) or equivalent, is recommended.

Cover setscrew
Capillary tube
Unscrew the setscrew with a screw-
driver to remove the cover from the
case.
Install the main unit and the
temperature sensor considering
length of the capillary. No direction is
specified for installing the main unit.
Capillary tube is wound up in a coil.
Unwind the tube only for the
necessary length.
Place the coil near the main unit.
Caution for installing the temperature sensor
For an accurate temperature control, install the temperature
sensor correctly.
Install it in a place where the representative temperature of
the controlled substance can be measured.
Knockout hole for wiring
Before the installation, remove the knockout hole on the top or
bottom surface of the case, which will be used to lead in the wires.
The capillary tube can be taken out from the top of the main unit.
Mount the main unit using the screws and nuts through the 3
mounting holes on the rear side of the case.
(Screws and nuts are included in accessories.)
Heat insulator
For mounting on a surface which is excessively heated, insert
a heat insulator between the back surface of the case and the
mounting surface.
Temperature sensor
The installation varies depending on applications.
For liquid, the immersion well (Model 112624AA-J) or the
pressure fitting (Model 83165370-001) is used.
For air duct, the temperature sensor holder (Model
DY3002A1011) is used.
These parts are to be ordered separately. For installation,
refer to the following figures.
Capillary tube
Never bend sharply, twist, or cut the
capillary tube.
The unit will be inoperative.
Allow enough clearance for setup
and adjustment.

Temperature sensor
Fix the capillary tube
with the spring clip
included in the
immersion well.
If the temperature sensor moves due to the
controlled substance orbends due to its own
weight, hold it straight.
Insertion length needs to be as short as possible
to avoid damage to thecapillary tube.
Seal the screwed
joint.
Tighten with
a wrench.
Place the washers to fit
the projection of a
washer and the groove
of another washer.
