4.5 Position OPEN Target Plates (8) so they are in the full upward position for “left-hand” (counter-clockwise) opening valves.
Secure OPEN Target Plates (8) by tightening Screws (37a). See Fig. 6.
4.6 Determine the number of turns required to fully open the valve. See Table 1 for NIBCO valves. You should always confirm
actual turns required to open the valve by counting them.
4.7 Using Table 6, choose the closest “Number of Turns to Open Valve” and the corresponding “Distance Between Targets”
dimension “X”.
4.8 Measure and position both SHUT Target Plates (9) at dimension “X” from OPEN Target Plates (8). See Fig. 6.
4.9 Secure both SHUT Target Plates (9) by tightening Screws (37a) with an Allen wrench.
