Operation Manual
Applicable model: Series HRW
(Thermo Chiller)

Introduction

Thank you very much for purchasing DI control kit for our Thermo Chiller, Series HR W .
This manual is for operators who have enough knowledge for general industrial equipment and devices, and al so
thoroughly understand assembling, handling, and maintenance of them. Before assembling, handling, a nd
maintenance, read and understand this manual and the one for Thermo Chiller, Series HRW carefull y.
Installing of accessories has to be performed by a customer according to this manua l.
Refer to the operation manual for Thermo Chiller for warrant y.
This manual is subject to change without prior notic e .
Summary of option
- It is possible to control the electric resistance of circulating fluid as you like by using an ion exchange resin filt
(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 bur n.

- 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 oth er
purpose, or outside of the specification rang e .
- 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. Ke ep
this operation manual so that you can refer whenever necessar y.
- Do not perform installation work while power is on.
Perform lock-out and tag-out of the power securely. Otherwise, Thermo Chiller may operate unexpectedl y.
- Perform installation work without any circulating fluid in Thermo Chiller.
Perform the work before supplying circulating fluid in or after exhausting all the circulating fluid fr om
Thermo Chiller. The circulating fluid shoud be exhausted after the fluid gets to be ambient temperatur e.
Otherwise, an operator may get a burn or frostbit e.
Caution
!
- Do not disassemble or modify.
Otherwise it may cause leakage and operation failur e .
- 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 Ther mo
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 optio n.
Fig. 1
Procedure 1
er
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 tu be
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 rotatio n.
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 tu be
for OUT to the end of the DI circuit RETURN, and tighten the nut by hand. At that time, use two spanners, (3) a nd
n.
(4), not to rotate the self-align fitting. Turn the hand-tightened nut by 1/4 rotatio n.

Procedure
Mount a therml insulator for DI filter as shown at Fig. 2, and set it in the drain pan (only for the customers who purchas
it).
Procedure 4
Supply circulating fluid from IN side of the DI filter to exhaust air. Continue to supply until OUT side is fill ed
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 concentrati
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).
