1. Remove the hex bolt and washer from the valve stem. (These are no longer needed.) Also
remove the stop plate, valve stem retainer (bend if necessary), and wave spring (see valve exploded
view for part details—Section 6.3). Keep the valve stem and valve stem insulator bushing in place.

2. Press the two (2) small dowel pins into the bracket base [Figure 5.4-3], so that they are flush with
the flat side.
3. Place the bracket base onto the top of the valve, aligning the dowel pins with the holes on the
valve. [Figure 5.4-4]

4. Place the lower bracket on the bracket base. (Orientation of the bracket base affects the orientation of
the electric actuator, and must be determined by the installer.) Insert the four (4) long bolts through
the lower bracket and bracket base. [Figure 5.4-5]
