To determine lower tube distance from tank <br /> bottom to bottom of cut; <br /> Subtract valve length (W) from distance to tank <br /> bottom (B) <br /> Cast lug <br /> Mote; Lower tube clearance must meet tank manu- in 7150 <br /> facturer requirements and all AM, local, state, and na- body <br /> tional codes, Typical clearance Is about 4°. If lower Float direction <br /> tube clearance is not met valve must be removed and <br /> adjusted to meet these requirements. <br /> 3. To determine lowertube distance from tank <br /> bottom to top of cut: <br /> Subtract valve length (t,1) from distance to tank <br /> bottom (B) <br /> M (B) - ( u) = � <br /> view into drop tube from above <br /> Note: Lower tube distance from tank bottom to top <br /> of cut must meet all AM, local, state, and national <br /> codes. For reference per 40 CFO 63 subpart CCCCCC / <br /> NESHAP the lower tube can be no more than 6' from <br /> the bottom of the tank. If lower tube distance Is not <br /> met valve must be removed and adjusted to meet these <br /> requirements, <br /> 4 . To determine float alignment* <br /> i <br /> Looking into upper tube (see figure) the float should be <br /> aligned along the length of the tank. If float is not <br /> aligned properly adjustments need to be made. <br /> JA <br /> �\ <br /> 21 <br />
