3. Remove the housing nipple and cap from the top cable anchors and hang plumb lines from
their centers to mark the position where the bottom cable anchor will be welded to the
tank floor. Mark these positions on the tank floor.
4. Mark the plumb bob string at the height of the tank bench mark. This will assure that the
plumb bob just touches the bottom, when the reference is made from the bench mark dis-
tance to the bottom.
5. Hang a plumb line through the center of the top tape pipe to the bottom to mark the float
center. This should be 8.50 inches (216 mm) from each of the cable anchor positions pre-
viously marked on the tank floor.
For Carbon Steel and Stainless Steel:
6. When the positioning has been checked, weld the bottom cable anchor into place.
7. Thread the float guide cables into the tank through the top anchor fittings. Fasten them to
the bottom cable anchor with the furnished hardware.
