Caution
Using the External Pilot
1. If a pressure difference over 0.1 MPa between
the supply and the set pressure cannot be
maintained, change to an external pilot to
obtain the necessary pressure difference.
2. If a mist separator cannot be installed on the
supply side, change to an external pilot, and
make sure to install a mist separator on the
pilot side.
