Operation Manual
Applicable model: Series HRW
(Thermo Chiller)
Introduction
Thank you very much for purchasing DI control kit for our Thermo Chiller, Series HRW.
This manual is for operators who have enough knowledge for general industrial equipment and devices, and also
thoroughly understand assembling, handling, and maintenance of them. Before assembling, handling, and
maintenance, read and understand this manual and the one for Thermo Chiller, Series HRW carefully.
Installing of accessories has to be performed by a customer according to this manual.
Refer to the operation manual for Thermo Chiller for warranty.
This manual is subject to change without prior notice.
Summary of option
- It is possible to control the electric resistance of circulating fluid as you like by using an ion exchange resin filter
(hereafter DI filter) and electric resistance meter (hereafter DI sensor).
- DI filter is not attached. Purchase our HRZ-DF001 separately if you need. If the DI filter is used at temperature out of
the range, 20 to 40degC, also purchase a thermal insulator, HRZ-DF002, to prevent frostbite and a burn.
Safety instruction
- Understand the meaning of the following signs before reading the body of this manual, and keep the instruction.

- Before using, understand the specification range thoroughly.
This product is designed as an option for Thermo Chiller, Series HRW. Do not use this product for the other
purpose, or outside of the specification range.
- Understand the contents of this manual and the working procedure thoroughly.
Understand this manual and the one for Thermo Chiller (Document no: HRX-OM-K003) thoroughly. Keep
this operation manual so that you can refer whenever necessary.
- Do not perform ins t alla t i o n work wh il e power i s o n .
Perform lock-out and tag-out of the power securely. Otherwise, Thermo Chiller may operate unexpectedly.
- Perform installation work with o u t any c i r c ulat i ng f l uid i n Th er mo C hiller.
Perform the work before supplying circulating fluid in or after exhausting all the circulating fluid from
Thermo Chiller. The circulating fluid shoud be exhausted after the fluid gets to be ambient temperature.
Otherwise, an operator may get a burn or frostbite.
- Do not disassemble or modify.
Otherwise it may cause leakage and operation failure.
- Confirm there is no leakage or condensation after installation.
Confirm there is no leakage or condensation with Thermo Chiller operated. If leakage is found, stop Thermo
Chiller immediately.

Accessory installation
Introduction
Refer to the accessory list on the back, and confirm the number of the accessory. In addition, confirm the
model no. plate on the body has "-Y" indication, which is symbol for this option.

Procedure 1
Confirm that a nut, a ferrule, and an insert are installed at the end of the DI tube for IN (Fig. 1). Insert the DI tube
for IN to the end of the DI circuit Supply, and tighten the nut by hand. At that time, use two spanners, (1) and (2),
not to rotate the self-align fitting. Turn the hand-tightened nut by 1/4 rotation.
Procedure 2
Confirm that a nut, a ferrule, and a insert are installed at the end of the DI tube for OUT (Fig. 1). Insert the DI tube
for OUT to the end of the DI circuit RETURN, and tighten the nut by hand. At that time, use two spanners, (3) and
(4), not to rotate the self-align fitting. Turn the hand-tightened nut by 1/4 rotation.

Procedure 3
Mount a therml insulator for DI filter as shown at Fig. 2, and set it in the drain pan (only for the customers who purchased
it).
Procedure 4
Supply circulating fluid from IN side of the DI filter to exhaust air. Continue to supply until OUT side is filled
with circulating fluid.
Procedure 5
Connect the DI tube for OUT and DI tube for IN to OUT side and IN side of the DI filter respectively. As the DI
tube has a strainer and a packing at the DI filter connection part, be careful not to drop them (Refer to Fig. 3).
Procedure 6
Perform trial operation in accordance with Thermo Chiller operation manual, HRX-OM-K003. Initially, the DI
filter has water. If ethylene glycol solvent is used, the concentration may be decreased. Confirm the concentration
after the trial operation. The proper concentration of ethylene glycol is 60%. If no leakage is found, install a
insulator to a ball valve connected to the DI tube, and fix it with a band (Refer to Fig. 4).

desire with [ ], [ ], and [ ] keys. After setting the value, press [ENT] key.
(3) Setting of DI level lowering alarm (LOW DI)
Set a cursor on "LOW DI" on the screen "Initial setting 4", and press [ENT] key. Set the value to the one you
desire with [ ], [ ], and [ ] keys. After setting the value, press [ENT] key.
(4) Reset of DI ACC
Press [ ] and [ ] keys while the screen "DI ACC reset" is shown, and select [YES]. Then, press [ENT] key.
(5) Status of DI circuit
You can confirm it on the screen "Status 3".
External communincation
Only DI PV can be output by external communication (serial RS-485). Refer to the separate manual,
"Communication Specification/ HRX-PS-K005", for detail. If analog communication (option) is used
refer to "Communication Specification/HRX-PS-K018".

*1: DI filter (Part no.: HRZ-DF001) is necessary to control DI level. This optional product does not have DI filter,so
purchase it separately. If this product is used out of the range of 20 to 40degC, also purchase a thermal insulat or
for DI filter (our part no.: HRX-DF002) to avoid frostbite and burn.
*2: Temperature correction is not applied to the DI level indication value.
Note: Temperature stability at supply of circulating fluid in the Thermo Chiller could be out of +/-0.3degC depending
on DI filter replacement and operating condition s.
