For water-cooled type.
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.
It is recommended to use heat insulation to reduce the heat radiation
and absorption to/from customer's piping.
Check the model number of this product in "1.4 Product Label
