KINGSLEY(FRONTAGE RD) HWY 99 @ ARCH <br /> AIRPORT RD, STOCKTON, CA 95206 <br /> Appendix 0 <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 /> Tank ID: 89(MUL) <br /> Take the following measurements with the valve in- j <br /> stalled in the tank: <br /> Distance from the 71 SO inlet tube flange to the cast C <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)= 51.125 <br /> Distance from the 71SO inlet tube flange to the top and <br /> bottom of lower tube,valve length. <br /> D) i r7 <br /> (V1)_ <br /> (U)_ Upper <br /> 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 0.6°) ; (W)Valve 'r <br /> (B)_ 132.5 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. (B) <br /> (y)= 9684 _ To Tank <br /> (Y) <br /> 1. To determine shut-off percentage: Tank <br /> Subtract upper tube length(D)from distance to tank (u)valve Chart <br /> bottom(B) Length, 100%Vol- <br /> (X)=(B)—(D)-2"= 79.375 top of cut ume Dip- <br /> stick <br /> Using the tank calibration chart provided by the tank <br /> manufacturer determine the tank capacity at the cal- <br /> culated(X)dimension and the 100%volume(Y)tank <br /> capacity. <br /> (X)tank capacity In gallons= 9116 <br /> (Y)tank capacity In gallons=9684 <br /> SO%=(X)capacity/(Y)capacity x100= 94.1 <br /> Note: The overfill valve must be installed per AHJ require- <br /> ments and all applicable local,state,and national codes. 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 />
