All length measurements are in Inches. Please contact the Authority Having Jurisdic- <br />on (AHJ) and review local, state, and national codes to determine the regulatory raWremer►ts gov*min9 <br />shutoff capacity in your rtglon, as Weil as take irrto account other considerations such as extreme tank tilt. <br />Take the following measurements with the valve Irt- <br />"led in the tank: <br />Distance from the 715D inlet tube flange to the cast <br />lug in the 7150 body (see figures), upper tube length. <br />Note: the Lipper Tube Length must be at least 16" to <br />Include the protective bend in the tube. <br />lar = <br />Distance from the 7t54 inlet tube flange to the top and <br />bottom of lower tuber valve length. <br />(W) <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 />(flPW 6111 1TP models add 0.8") <br />From the tank calibration chart provided by tank manu- <br />facturer find the dipstick number (Y) which corresponds <br />to the 10 wo Te. <br />(Y) <br />1. To determine shut -oil percentage: <br />5ubtract upper tube length (D) from distance to tank <br />bottom (6) ` <br />(x)=(8)—(1))-2"_ <br />Using the tank Wibration 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 />[YJ tank capacity in gallons - "2- <br />Y ' <br />D94 = (X) capacity ! (Y) capacity x100 <br />Note: The overfill valve must he installed per AM require- <br />ments and al i applicable local, state, and nationai codes. If <br />the overfill valve is set above the aIIowa bie shut-off percent- <br />age the overfill valve must be removed and replaced. For <br />reference 40 CFR part 280 Subpart 9 Section 2 80.2 0 overfill <br />valves should be set to a maximum of 95%. <br />20 <br />
