10. Thread the turnbuckle onto the left hand threaded rod end (Figure 12).
11. Adjust the turnbuckle until the hole in the SVI II AP lever is aligned with the
indicating hole in the bracket. Tighten both turnbuckle lock nuts. Refer to
Figure 11.
12. For reciprocating valves the adjustable link turnbuckle must be parallel to the

with the indicating hole in the bracket when the valve is in the closed position.
Check that the bracket is mounted using the proper holes. (Refer Table
