Stockton, CA 95202 <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(ARA 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 /> Tank ID: PREM.(PREMIUM) <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 /> (D)= 53.25 <br /> Distance from the 71 SO inlet tube flange to the top and <br /> bottom of lower tube,valve length. (D) <br /> (W)= — — Upper <br /> (U)= -- _ _ Tube <br /> Distance from the 71 SO inlet tube flange to the bottom <br /> of the tank. Note:If a tank bottom protector is present it <br /> may be necessary to add this thickness to dimension <br /> (OPW 6111&61 TP models add 0.61 (W)Valve <br /> (g)= 162 _ _ Length, <br /> bottom of <br /> From the tank calibration chart provided by tank manu- cut <br /> facturer find the dipstick number(Y)which corresponds <br /> to the 100%volume.

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 45%. <br /> 20 <br />
