CAUTION: Never disconnect the drop elbow from the tight -fill adapter when the <br />A1100 has reached the positive shut-off level. At this point, the tank truck hose <br />is still full and must not be disconnected until enough fuel has been removed <br />from the underground storage tank to drain the hose. Premature disconnection <br />will result in a hazardous spill and a potential for personal injury and property <br />damage. <br />WARNING: If the underground storage tank is equipped with a ball float vent <br />valve, make sure it is not extended below the positive shut-off point of the <br />A1100, or remove the float vent valve. <br />Tools Needed <br />1. 1/8" pilot drill bit 6. hammer <br />2. 13/64" drill bit 7. fine half round file <br />3. hand drill 8. heavy duty pop rivet gun <br />4. tape measure 9. masking tape <br />5. fine tooth hacksaw (24-36 teeth per inch) <br />Optional: Drilling fixture #566675, recommended <br />WARNING: Do not use electrical devices near gasoline vapors, as it could <br />result in fire or explosion. <br />Packing List (included with A1100-010) <br />(1) valve assembly #A1100 (8) pop rivets #564412 <br />(1) hose clamp #564421 (1) o -ring #480049 <br />(1) warning plate #564420 (1) counter sink indenter #564416 <br />(1) drop tube O-ring #561683 (1) Seal -All sealant #566726 <br />NOTICE: If this valve is to be used with coaxial Stage I drop tube assemblies, <br />you must order the appropriate special kit for proper assembly: <br />Standard coaxial (A0070 style) kit #493195 <br />Self sealing coaxial (A0088 style) kit #493197 <br />TOP TUBE INSTALLATION PROCEDURE <br />The A1100 Guardian can only be installed after the containment manhole has <br />been installed. Existing drop tube may be used only if: <br />1. Tube is in good condition without holes, cracks, or bends. <br />2. I.D. of tube will fit over the valve body diameter. <br />Sten 1: If already in place, remove the existing 4" cap, adapter and drop tube <br />assembly. <br />Step 2: Find measurement A which is the distance from the top of the tank to <br />the top of the 4" riser pipe as shown in Figure 1. If the tank has a manway, <br />make sure to include the height of the manway when finding measurement A as <br />2 shown in Figure 2. <br />
