Assembly Instructions <br /> Before you begin assembly,clear the inside diameter of the riser pipe of any burrs,improper reaming,or foreign material. <br /> Failure to adequately clean the inside of the riser pipe may damage or prevent the valve from functioning properly. <br /> 1. Remove the fill cap,adaptor, and existing drop tube Be certain to add the manway height to the`B"dimension <br /> from the riser pipe. Measure from the inside top of when the 708 Auto Limiter is used in manway applications <br /> the tank to the top of the riser pipe(see Dimension (see Figure 3). <br /> "A"in Figure 2&3). 3.To determine the correct length of the upper drop <br /> tube add dimension"A"to"B"and subtract 4" <br /> 705 Sp <br /> ill (1 O2 mm). <br /> + - 4"(102 mm)"A" "B" "C"(Drop Tube Length) <br /> For tanks with manways,add dimensions"A"to"B"to <br /> manway height and subtract 4"(102 mm)to get the drop <br /> tube length. <br /> .i. + _ 4" c <br /> "A" "B" Manway Height (102 mm) "C"(Drop Tube <br /> Figure 2 Length) <br /> 4. Mark the dimensions on the upper drop tube. <br /> 4a. For dual point applications,measure down from the <br /> n°�aofaRiservvilh emoved flange and mark dimension"C'on the drop tube <br /> (see Figure 4). <br /> 4b. For coaxial installations, measure down from the <br /> Riser Pipe bottom side of the top adapter's supporting lugs <br /> MamvayHeight 1 and mark dimension"C"on the drop tube(see <br /> L Figure 5). For coaxial€nstallations,go to Step 7. <br /> "$,. <br /> 05%of Full Tank a s t s{rt <br /> Tank d <br /> Figure 3 3b <br /> 2. Determine the 95%shutoff point for your tank from <br /> the tank chart provided with the tank or from a <br /> calibrated gauge stick.To determine your actual <br /> "B"dimension,subtract the 95% level height from <br /> the overall tank diameter(tank diameter(inches) a <br /> -95%level(inches)="B"dimension).The chart -Figure 4 Measure from Flange <br /> below is provided for reference only(see Figure 1). <br /> Your actual"B"dimension will vary slightly based <br /> upon your actual overall tank diameter head and <br /> bulkhead design. _ <br /> Apex Dithonsion <br /> Tank Dlameter <br /> "B1.for,96WShutoff ; <br /> 4 feet(122 cm) 5"(127 mm) } <br /> 5 feet(152 em) 6"(152 mm) <br /> 6 feet(183 cm) 7 1/2"(191 mm) <br /> 7 feet(213 cm) 8"(203 mm) <br /> a feet(244cm) 91/2"(241 mm) <br /> 9 feet(274 cm) 10 1/2"(267 mm) Figure 5:Measuring for Coaxial Installations <br /> 10 feet(305 cm) 13"(330 mm) 5.
