∗1 For NPT and G thread, use a conversion connector available as an accessory separately.
∗2 For water-cooled type.
∗3 For automatic fluid filling [Option]
Connect piping firmly. Incorrect piping might cause leakage of
supplied or drained leakage and wet surrounding area and facility.
Keep supply water pressure below 0.5MPa.
Pay attention not to allow dust and foreign materials to enter into
water circuit etc. during connection of piping.
When the thermo-chiller is water-cooled refrigerated type, the
temperature of the outlet of the facility water may become approx.
60℃ depending on operating conditions
Hold the piping port firmly with specific wrench when tightening.
The piping should be selected with due consideraton of pressure and
temperature. Otherwise, the piping can burst in service.
Check the model number of this product in "1.4.1 Product Label” of
this manual before connecting piping.
Model number: HRS0∗∗-∗N-∗0
The transition connector from Rc to NPT is enclosed as an
accessory.
For NPT piping, be sure to use this connector.
Model number: HRS0∗∗-∗F-∗0
The transition connector from Rc to G is enclosed as an accessory.
For G piping, be sure to use this connector.
