Tank ID: RUL T2 <br /> Appendix B <br /> 71 SO Overfill Valve in Tank Shut off Level Worksheet <br /> Important: This is meant to be supplemental worksheet and not a substitute to following the installation <br /> manual instructions. All length measurements are in inches. Please contact the Authority Having Jurisdic- <br /> tion(AHJ)and review local,state,and national codes to determine the regulatory requirements governing <br /> shut-off capacity in your region,as well as take into account other considerations such as extreme tank tilt. <br /> Take the following measurements with the valve in- <br /> stalled in the tank: <br /> Distance from the 71 SO inlet tube flange to the cast <br /> lug in the 71 SO body(see figures),upper tube length. <br /> Note: the Upper Tube Length must be at least 16°to <br /> include the protective bend in the tube. <br /> 74.25 <br /> (D)=— - <br /> Distance from the 71 SO inlet tube flange to the top and <br /> bottom7of lower tube,valve length.

If <br /> the overfill valve is set above the allowable shut-off percent- <br /> age the overfill valve must be removed and replaced. For <br /> reference 40 CFR part 280 Subpart B Section 280.20 overfill <br /> valves should be set to a maximum of 95%. <br /> 20 <br />
