B-2. Position the actuator at 0 % (full close), and set the actuator limit switch so as to work at 0 %.
(Note that the limit switch should normally be set to work at a half turn of manual handle past the full close of
signal rate.) (See FIG.9)
B-3. Bolt a bracket on the valve.
B-4. Tentatively bolt the actuator on the bracket.
B-5. Position the actuator at 0% (close), then joint the actuator shaft and the valve stem with a coupling.
B-6. Secure the bolts.
B-7. Manually check that the actuator turns smoothly without eccentricity etc.
Confirm that the limit switch works at 0 % before the shaft touches at the stop.
(If the shaft touches at the valve stop before the limit switch would function, the actuator may be locked, and
may overheat.
In such a case, the thermo protector will stop the motor, but the case may cause damages to the unit.)
