A1100 Guardian <br />(A1100-004 Shown) <br />u <br />The A1100 Guardian is a two <br />stage automatic shut-off, <br />overfill prevention device. <br />The Guardian simply installs <br />into a new or existing 4" drop <br />tube assembly, including <br />conventional or dual point <br />vapor recovery systems. Since <br />it does achieve positive shut- <br />off, the A1100 can be installed <br />at a higher tank capacity per <br />the EPA's U.S.T. regulations. <br />The Guardian's unique design <br />includes internal self-cleaning <br />Teflon floats eliminating <br />problems with external floats <br />sticking or being damaged <br />upon installation. A large <br />shock relief valve incorporated <br />into the main poppet drama- <br />tically reduces line shock. The <br />high drain rate secondary <br />bleed valve supplies fast hose <br />drainage eliminating unneces- <br />sary delays. The A1100 in- <br />cludes an automatic reset <br />poppet so you can stick the <br />tank without damaging the <br />valve. Since the Guardian does <br />not require a specially manu- <br />factured drop tube, it can be <br />shipped quickly and easily in <br />its convenient small box. The <br />A1100 is CARB Certified for <br />both dual point and spring <br />loaded coaxial systems. <br />i <br />i <br />B <br />Cm <br />Model No. <br />System* <br />Drop Tube <br />Weight <br />A <br />B <br />(Drop Tube) <br />Support Adapter <br />A1100-001 <br />Conventional/Dual <br />493391 <br />41/2 lbs. <br />313/16" <br />161/16" <br />System (A20) <br />(supplied) <br />A1100-001 <br />Standard Coax <br />493195 <br />41/2 lbs. <br />3 13/16" <br />16 7/16" <br />(A70) <br />(order separately) <br />4 1/2 lbs. <br />3 13/16" <br />16 7/16" <br />A1000-004 <br />Spring Loaded <br />493197 <br />41/2 lbs. <br />3 13/16° <br />16 7/16" <br />Coax (A88) <br />(supplied) <br />Replacement Parts: Standard Tube Support Collar: 493391, Drop Tube Rivets: 564412, 0 -Ring: 480049, <br />Dimple Tool: 564419, Instruction Book: 564417, Warning Plate: 564420, Clamp Band: 564421 <br />Optional Parts: Coax Kit (A70): 493195, Standard Drop Tube: A20, Coaxial Tube: A70, Spring Loaded <br />Coax Tube: A88 <br />Material: Body: Hard Coat Anodized Aluminum, Floats: Teflon, Seals: Buna, Diverter: Stainless Steel <br />"See page 6 for explanation of system applications. <br />Note: If the field drop tube is a thick wall tube and will not fit A1100, the thick wall drop tube adapter <br />Kit #493418 must be used.
