If lower tube distance is not met valve must <br /> be removed and adjusted to meet these requirements . <br /> 4. To determine float alignment: <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 /> I <br /> E <br /> { <br /> 22 <br />
