We recommend using water with the low amount of impurities (such as
industrial water shown in the table below) for cooling water of this product.
Water stain, such as calcium carbonate, accumulates in the cooling water
system of this product depending on the water quality, which reduces the
cooling efficiency. In addition, chlorine ions may corrode from the inner
wall, causing cooling water leakage. Note that in such a case, the repair
will be charged.

Before removal, be sure to disconnect it from the power supply.
The pump keeps its temperature extremely high while the pump is running
or for a while after it stops. If someone's body comes into contact with it,
the person may get burned. Supply the cooling water until the pump
