open end wrenches and tighten.
Slide the groove of the stem adapter in to the actuator linkage 5.
slot and position the actuator on to the valve.
Engage the large valve nut several turns on to the actuator yoke 6.
by hand (the valve stem may be pushed into the valve during
this process).
To create plug and seat clearance before  nal assembly tighten-
ing, lower the Red Manual Override Lever and rotate clockwise
 ve turns (looking from the bottom of the actuator). If you skip
