Note
1.This product is designed as an option for Thermo chiller, Series HRW. Do not use this product for the other purpose, or outsi de
of the specification range.
2.Installation of accessories has to be performed by a customer according to the operation manual.
3.Supply circulating fluid from IN side of the DI filter to exhaust air. Continue to supply unitl OUT side is filled with circulati ng
fluid.
4.The DI filter has water inside. 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 %.
Dimensional tolerance for each: 10mm

*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 bur n.
*2: Temperature correction is not applied to the DI level indication valu e.
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.
