9) Hold the electric conductivity sensor cable with the cable fixture (13) and
cable tie (14), if necessary.
10) Mount the DI filter cartridge (10), referring to section [3.3. Replacement
of DI filter cartridge]. Open valve and start operation of the thermo-chiller
to fill the filter case with fluid to remove air inside the case.
11) After confirm that there is no fluid leakage, exhaust air from the vessel of
the quick change filter.
12) Completion of assembly instruction.
Caution
When the product is delivered, there is no DI filter cartridge in the filter
case. Mount DI filter cartridge referring [3. Replacement DI filter cartridge]

3.3 Replacement of DI filter cartridge
1) Confirm that product operation has stopped and valve has closed
.
2) Remove the resin filter case with the handle, and remove the DI
filter cartridge.
Caution
Circulating fluid may spill from the resin filter case when loosened. Place
a container, e.g. bucket, under the filter case before starting replacement
of the DI filer cartridge.

3) Put a new DI filter cartridge into the case. Place the DI filter cartridge so
that the seal faces upward. Mount the resin filter case by hand tighten.
Caution
・Mounting of the case should be performed by hand-tighten. When the
case is tightened excessively by tools or handle, the case might crack or
be damaged.
・Make sure that the case is held manually by hand when removing and
mounting the case. If the case is dropped, it may result in cracking or
breakage.
4) Open valve and start operation of the thermo-chiller to fill the filter case
with fluid to remove air inside the case.
5) Confirm that there is no fluid leakage.
6) Completion of replacement of DI filter cartridge.
Caution
The fluid level of the thermo-chiller will be reduced when the air in the
vessel is discharged during the replacement of DI filter cartridge. Refill the
circulating fluid in advance.
If the fluid level becomes too low, it will cause the alarm “AL01; Low level
in tank", which will stop the thermo-chiller operation.

Chapter4 Setting procedure
4.1 Setting of electric conductivity sensor function
and control function
Electric conductivity will not be displayed and controlled only by connecting the electric
conductivity control set. Follow the instructions below to enable the electric conductivity
sensor function and control function.
1. Turn the thermo-chiller ON, and confirm that power is supplied to the product.
2. Press and hold the [MENU] key (for 2 seconds) twice on the [Main screen] to switch the
screen to the [Setting menu]. (Refer to Chapter 6 "Key operation list")
3. Press the [SEL] button for 18 times. The electric conductivity sensor function
enable/disable setting screen [SE.19] is showed on the digital display.
Select “dI.2” with the [▲] or [▼] key, and press the [SEL] key to enable the function of
the electric conductivity sensor.
-Default is “oFF(disable)”.
-When [SE.19] set up [dI.2], maximum setting value of [SE.25], [SE.26] and [AS.08] are
changed. Please refer to the operation manual of the thermo chiller.
4.Press the [SEL] button once.The electric conductivity control function enable/disable
setting screen [SE.20] is showed on the digital display.
Select “on” with the [▲] or [▼] key, and press the [SEL] key to enable the function of the
electric conductivity control function.

"----" for the electric conductivity hysteresis setting (SE.22).
-Default is “5.0μS/cm”.
-Settable range of electric conductivity hysteresis is 2.0 to 10.0μS/cm.
7. Press the [MENU] key once to return to [main screen]. When the [SEL] key is pressed
twice on [Main screen], the electric conductivity is displayed.
-If the electric conductivity sensor function is disabled (if [SE.19] is [oFF]), the display shows

-The display shows within the range of 2.0 to 48.0μS/cm.
-If Electric conductivity goes under 2.0μS/cm, the display shows [Lo], and if Electric conductivity
exceeds 48.0μS/cm, the display shows [Hi].
Caution
Current consumption of this electric conductivity control set is 400mA. The
thermo-chiller HRSH series supplies 24 VDC (Max. 500mA) from the contact
input/output port. If this electric conductivity control set is used, current that is
available from the contact input/output port when using 24 VDC is 100mA.
