1.
When installing the product with the coil set sideways, make sure that the differential pressure (the
minimum differential pressure to operate the valve) between the inlet and the outlet is 0.1 MPa or
more (see Table 1 on Page 1).
* Failure to follow this notice may result in an abnormal operation.
2.
Though the product can be installed at any angle between vertical and horizontal, it cannot be
