2. To determine lower tube distance from tank <br /> bottom to bottom of cut: , <br /> Subtract valve length (W) from distance to tank <br /> bottom (8) <br /> (V) _ (8} — (w) <br /> Cast lug <br /> Note: Lower tube clearance must meet tank manu- in 71 So <br /> facturer requirements and all AHJ, 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 lower tube distance from tank <br /> bottom to top of cut: <br /> Subtract valve length (U) from distance to tank <br /> bottom (8) <br /> View into drop tube from above <br /> Note: lower tube distance from tank bottom to top <br /> of cut must meet all AHJ, local, state, and national <br /> codes. For reference per 40 CFR 53 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 /> Looking Into upper tube (see figure) the float should be <br /> aligned along the length ofthe tank. if float is not <br /> aligned properly adjustments need to be made. <br /> 21 <br />
