
Connect piping firmly. Incorrect piping might cause leakage of
supplied or drained fluid and wet surrounding area and facility.

Use caution not to allow dust and foreign matter to enter the water
circuit, etc. during connection of piping.

Securely connect the piping at the piping port with specific wrench
when tightening.

Incorrect piping can burst in service.

Use non-corrosive material for fluid contact parts of circulating
fluid and/or facility water. Using the materials that tend to rust or
corrode may cause clogging or/and leakages of the circulating
fluid and facility water circuits. In case of using these kinds 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.
Internal parts of the product and/or the piping may be damaged.

Facility water temperature of the facility water outlet port might
rise up to approx.60deg.C.
