Smooth and slope per the tank bedding instructions. 4 . Proceed with setting the tanks by adding ballast as necessary to sink and keep down the tanks. Use only enough ballast to hold the tanks down until the backfill is even with the top of the tanks. (Refer to tank setting requirements. ) Caution: Ballast level in tank must never exceed water (or backfill) level in tank hole during installation. 5.

One end of each cable is to be crossed over the top of the tank in the retainer portion of the hold-down strap. Using three cable clamps on each set of cables, clamp both cables together on top of the tank. Prior to tightening the clamps, tension the cables with "come-a-longs" secured outside the tank hole. Use enough tension to tighten the cables but not to lift the "logs" or crush the tank. Caution: All sets of cables on a tank must be tightened equally to avoid tank deformation. b.
