Optional Top Cable Clamp Method <br />• May be used to secure anchor straps at the top of tank. <br />• Clamp cable to strap using at least 3 cable clamps. <br />• Thread cable around deadman (or through anchor <br />points). <br />• Bring cable to top of <br />tank. <br />• Position wire rope in <br />cable guides. <br />• Repeat procedure on <br />other end of strap. <br />• Clamp cables together <br />at top of tank. <br />• Use a come -along to <br />snug wire rope. <br />• Secure cables with at <br />least 3 cable clamps. <br />A8. Installation Procedure <br />Before you begin: <br />Guides Hold <br />Cables <br />It's important you review all instructions to make sure that <br />the proper procedures and materials have been complied <br />with. This includes: <br />❑ Bed and Backfill <br />❑ Pre -Installation Testing <br />Cl Hole Size/Burial Depth <br />❑ Anchoring <br />Tank Installation - Warnings and Cautions <br />AWARNING] <br />• Do not enter the tank excavation unless necessary! <br />Follow OSHA guidelines for tank excavations. <br />• Collapsing excavation walls can cause injury or death! <br />DO <br />• Backfill the tank as soon as possible to tank top. <br />• Ballast tank with water or product after backfill is even <br />with tank top. <br />DO NOT <br />• Place water or product in tank until backfill is even with <br />tank top! <br />Installation Procedure - Dry Hole <br />(OSHA - Sloped Excavation Walls) <br />Bed <br />DO <br />• Provide a minimum of 12" bedding using approved back- <br />fill material (see section A2). <br />• Set tanks directly on backfill bed. <br />DO NOT <br />• Place tanks directly on concrete pad, timbers, cradles or <br />beams. <br />Backfilling (All tank models) - Proper backfilling is un - <br />portant to provide necessary support for the tank. <br />It is critical to: <br />• Use approved backfill material. <br />• Place the first 12" lift everily around tank. <br />• Use a long handled probe to push backfill completely: <br />❑ Beneath <br />tank bot- <br />tom. <br />❑ Between all <br />ribs. <br />❑ At3to5 <br />points un- <br />der end <br />caps. <br />• Place another <br />12" of backfill <br />to insure proper <br />support. <br />Long Handled Probe <br />rF 12" Liftackfill <br />s <br />V <br />It's critical that this area offer full <br />support under tank and end caps. <br />• Repeat the probing of backfill to insure proper support. <br />• After completion of second lift, backfill can be brought <br />to top of tank without additional handwork (compaction <br />may be required for slab support). <br />To minimize the chance of tank buoyancy, backfill the <br />tank as soon as possible to tank top and then ballast (fill <br />tank) with water or product. <br />Do not place water or product in tank until backfill is <br />even with tank top. <br />9 <br />
