CAUTION
To manually open or close the valve, be sure
to disconnect from the power supply
(100 V AC/200 V AC). If the valve is manually
opened or closed with the power applied, the
actuator may be damaged.
To prevent your finger from being pinched
and injured, do not put your fingers between
the main unit and the indicator/manual lever,
especially on the area with

Be sure to disconnect the power supply before manually
opening/closing the valve (DN15, DN20, or DN25 size).
Adjust the indicator/manual lever with the lever release but-
ton (as shown in Fig. 10) pushed in. Do not use any tool to
adjust the indicator/manual lever.
