EBW Auto Limiter 11 Valve Component <br />Inspection Procedure <br />EBW's Autol-irniter 11 drop tube mounted overfill <br />prevention valve includes an inspection port for <br />the addition of a small, resealable inspection <br />port though, an inspection of the valve's internal <br />flapper assembly can now also be done. <br />Periodic Auto Limiter Component and <br />Function Inspection <br />Looig Needed <br />* #2 Phillips Screwdriver <br />* Flashlight <br />* EBW Service Kit (Part #90082) <br />* Tape Measure or Dipstick <br />Warning The storage tank may be under <br />Apressure. Vent the tank prior to <br />removing this drop tube. Highly <br />combustible petroleum vapors <br />sparking tools. <br />7osSpill Containment (Ref.) <br />Figure A <br />1. Remove the fill adapter from the spill containment <br />riser pipe. <br />2. Using odip stick ortape measure, determine the <br />height ofthis flange off the bottom ofthe tank. <br />Record this dimension. <br />�� <br />�� <br />@. Remove the drop tube/valve assembly from the <br />storage tank fill riser. <br />4. Place the drop tube assembly ona flat surface with <br />the float side ofthe overfill valve up. <br />6. Lay your tape measure ordipstick next tothe <br />drop tube aligning the top flange tothe dimension <br />number obtained from Step 2.Locate, onthe <br />overfill valve assembly, the machined ring adjacent <br />tothe upper float. This ring should beidentified <br />with a^&5%"stamp. Record the dimension nn <br />the dip stick mrtape measure that aligns with this <br />^0596^identification ring. This iethe second stage <br />shutoff point for this valve installation. This should <br />boset hVrnomore than S5Y6oftank capacity. <br />Figure B <br />M. From the tank chart for this tank, determine the <br />dimension off of the tank bottom for 95%oftank <br />capacity. Compare this determined dimension to <br />the dimension obtained inStep 5.Your calculated <br />g696capacity dimension should bmequal to, or <br />greater than, the actual dimension measured in <br />Step 5.|fyour calculated dimension ielower, then <br />the installation for this overfill valve imincorrect and <br />needs bubmimmediately addressed. <br />7. Locate the Phillips head screw onthe right side of <br />the float linkage (Figure C).Remove the screw and <br />save it for reinstallation. <br />ENVIRONMENTAL <br />10 <br />HEALTH DEPARTMENT <br />
