【Tips】
<In case of HRSH∗∗∗-∗N-∗>
A set of thread adapters that converts the connections from Rc to NPT is
enclosed as an accessory. Be sure to use this for NPT piping.
<In case of HRSH∗∗∗-∗F-∗>
A set of thread adapters that converts the connections from Rc to G is
enclosed as an accessory. Be sure to use this for G piping.
z Connect piping firmly. Incorrect piping might cause leakage of
supplied or drained leakage and wet surrounding area and facility.
z Pay attention not to allow dust and foreign materials to enter into
water circuit etc. during connection of piping.
z Hold the piping port firmly with specific wrench when tightening.
z The piping should be selected with due consideraton of pressure
and temperature. Otherwise the piping can burst in service.
