How to connect piping
Tighten the piping to
circulating fluid outlet
/
return port and
facility water outlet / inlet.
Fig. 3.4-1 Tightening of piping
Connect piping firmly. Incorrect piping might cause leakage of
supplied or drained leakage and wet surrounding area and facility.
Pay attention not to allow dust and foreign materials to enter into
water circuit etc. during connection of piping.
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.
Do not use the materials that rust or corrode for the circulating fluid
circuits. Using the materials that tend to rust or corrode may cause
clogs or/and leakages of the circulating fluid circuits. In case of
using these kind of materials, consider and carry out some
prevention against the rusting or corrosion by the customer side.
Do not generate a rapid change of pressure by water hammer etc.
The product and external piping might be damaged.
