Replacement of the SI unit
•Remove the M3 hexagon screw from the SI unit and release the SI unit from the
valve manifold.
•Replace the SI unit.
•Tighten the screws with the specified tightening torque. (0.6 Nm)
Precautions for maintenance
•Be sure to switch off the power.
•Check there is no foreign matter inside the SI unit.
•Check there is no damage and no foreign matter being stuck to the gasket.
•Be sure to tighten the screw with the specified torque.
If the SI unit is not assembled properly, inside PCBs may be damaged or liquid and/or
dust may enter into the unit.
Connecting cables
Select the appropriate cables to fit with the connectors mounted on the SI unit.
