OPUS/ Installation, Operation, and Maintenance Manual, Page 50 Executive Order VR-102-I <br /> HOW TO LOCATE THE POSITION OF THE <br /> 71SO AT 95% TANK CAPACITY Measuring Stick <br /> The length of the upper tube and the placement of <br /> the 71 SO valve body determine the shut-off point <br /> Following the standard instructions for the OPW <br /> 71SO will provide for initial shutoff at 95%. In all <br /> cases,the upper tube length must be a minimum of <br /> 6-1/2"plus the length of the riser pipe. All length <br /> measurements are in inches. Riser Pipe <br /> Iwith Face (A) <br /> INSTRUCTIONS <br /> Seal Adaptor To Tank <br /> Top(I.D.)

Bottom <br /> 2.)Calculate 95%of capacity. <br /> 3.)Locate the 95%volume number on the tank <br /> calibration chart. <br /> 4.)Find the dipstick number(X)which corresponds Figure 1 <br /> to the 95%tank volume. And,find the dipstick <br /> number(Y)which corresponds to the EXAMPLE <br /> 100%volume. 1.)For an Owens-Corning Model G-3 Fiberglass® <br /> 5.)Subtract the dipstick number(X)from the tank Tank Calibration Chart:Tank Capacity-10,000 gal., nominal 9,403 gal. <br /> diameter(Y)to find the upper tube reference NOTE: Use actual capacity only <br /> number(Z). <br /> (Y)-(X)=(Z) 2.)95%of actual tank capacity=0.95 x <br /> 6.)Subtract 2"from(Z)to find the upper tube depth 9403 gal.=8933 gal. <br /> (C)• 3.)The closest number which is less than 8933 gal. <br /> (Z)-2"=C Is 8910 gal.Choosing the closest number less <br /> than 95%of actual capacity ensures that the <br /> 7.)
