J� �Z <br />7150 overfill Valve in Tank Shut off Level Worksheet <br />Important This Is meant to be supplemental worksheet and not a substitute to fallowing the installation <br />manual instructions. Ali length measurements are In Inches. Please contact the Authority Haring Jurisdic- <br />tion (AHJ) and review focal, state, and national codes to determine the regulatory requirements 9oveming <br />shut-off capacity in your reg lon, as well as take into account other considerations such as extreme tank tItt. <br />Take the following measurements with the valve in- <br />stalled in the tank: <br />Distance from the 71 SO inlet tube range to the cast <br />lug in the 71St] body (see figures), upper tube length. <br />Note: the Upper Tu be Length must be at least 16" to <br />include the protective bend in the tube. <br />(D)= - <br />Distance from the 71 SQ inlet tube flange to the top and <br />bottom of lower tube, valve length. <br />(W) _ . YVA <br />(u) A <br />Distance from the 7150 inlet tube flange to the bottom <br />of the tank Note: ff a tank bottom protector is present it <br />may be necessary to add this thickness to dimension <br />[DPW 5111§ITP models add 0.6"] <br />a = / �- fG <br />From the tank calibration chart provided by tank manu- <br />facturer find the dipstick number (Y) which corresponds <br />to the 10 volu <br />m= 4����� <br />1. To determine shut-off percentage: <br />5ubtract upper tube length (D) from distance to tank <br />bottom (8) <br />(X)=(s)-(D)-2"= <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= <br />M tank capacity in gallons = G 7 Y ' <br />capacity! (Y) capacity x100 T <br />Note: The overfill valve must he installed per AW 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 fi Section 2 M2 0 overfill <br />valves should be set to a maximum of 95%. <br />20 <br />
