YOSEMITE AVE @ SPRECKLES, MANTECA, <br />CA 95336 <br />Appendix 8 <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 />shutoff capacity in your region, aswell as take into account other considerations such as extreme tank tilt. <br />TanklD: T:1(SUPREME) <br />Take the following measurements with the valve 1w <br />stalled in the tank: <br />Distance from the 71SO inlet tube flange to the cast <br />lug In the 7150 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 />lD) = 81.25. <br />Distance from the 7150 inlet tube flange to the tap and <br />bottom of lower tube, valve length, <br />{W1= <br />Distance hom the 7i50 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 & 61TP models add 0.61 <br />{B) = 185 <br />From the tank calibration chart provided by tank manu- <br />facturer find the d Ipstick number (Y) which corresponds <br />to the 100% volume. <br />(y) = 117.75 <br />1. To determine shut-off percentage: <br />Subtract upper tube length (D) from distance to tank <br />bottom (B) <br />{X) = (B) - (0) - 2' = 101.75 <br />Using the tank calibration chart <br />provided by the tank <br />manufacturer determine the tank capacity atthe cal- <br />culated (X) dimension and the 100%volume (Y) tank <br />capacity. <br />(X) tank capacity In gallons <br />= 13692 <br />{l7 tank capacity in gallons = 14976 <br />SO%= (X) capacity / (Y) capacity x100 = 92.8 <br />(D) <br />Upper <br />Tube <br />(W) Valve <br />Length, <br />bottom of <br />cut <br />(B) <br />To Tank <br />(Y) <br />Tank <br />(U) Valve Chart <br />Length, 100%vol- <br />top of cut umeDip- <br />stick <br />Note: The overfill valve must be installed per AHl require - <br />ants and all applicable <br />local, state, and national codes. If <br />the overfill valve is set above the allowable shut-off percent - <br />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 />
