Water quality

When the customer supplies pure water, use the water of class
A2 or above, as specified in JIS K0557: 1998, which does not
contain nitrogen and phosphorus compounds.

When a pure water unit is used, the tap water criteria defined by
the Water Supply Act must be met.
Supply method
Supply by the tank (standard) or continuous supply by the pure
water equipment (option)
Supply pressure 0.1 MPa to 0.5 MPa
