CAUTION:

Do not rotate the actuator on a Pressure

Independent Control Valve (PICV) once the

actuator and valve stem are connected. Doing so

will inadvertently adjust the flow setting of the

valve.

8. Secure the stem connection plate by tightening the

bolt, using a 10 mm wrench (or 4 mm hex

wrench). See Figure 10.
