cw - i ILJ <br /> INSTALLATION CLASS 2+3 <br /> Patent //- 6,871,455 <br /> The Nu-Concept GW-2 Anchor combines a patented elongated hole in the tension <br /> head with a stabilizing and compaction cap with drive rod guides. When combined <br /> with a grade 5 bolt, the anchor will rotate in all directions allowing adjustment to uneven <br /> terrain. Under load conditions the cap, rotates down ward in the direction of the pull, <br /> causing a double compaction of the soil and laterally restricts movement of anchor <br /> through the soil. Turn cap to position the drive rod guides facing away from the home, <br /> Insert 30"rods and drive to full depth into the soil, <br /> I . <br /> Attach stabilizer/compaction cap to the tension head of the anchor. This is done by sliding the <br /> ' cap over the top of the tension head, aligning 9/32" holes in cap with 1/4" elongated hole in <br /> tension head. Insert 1/4"x 2-1/4", grade 5 bolt(included). Hand tighten. Cap must be installed <br /> at any time prior to ground contact. See Cap FigureA and Tension Head Figure B. <br /> Figure A Figure B IL The Drive Machine is started and the anchor is <br /> (TOP) turned into the ground to a point where the bottom <br /> El of the tension head is at or slightly below ground <br /> (BOTTOM) <br /> 0 level, At this point,the drive rod guides on the top of <br /> the cap should be slanted away from the outer wall <br /> Class 2 Difficult soil of the home allowing the installer to drive the rods <br /> from the outside of the home. This insures <br /> Figure C maximum soil compression by the cap. See Figure <br /> C. Engineered to allow ground anchor to be <br /> installed at a slight back angle of 15° <br /> Stabilizer!Compacting <br /> < Head 2-30"Rods Class 2 - Difficult Soils <br /> co <br /> Stabilizer/Compacting <br /> i / ® 7 Head <br /> 110\ <br /> 111, Anchor is pre-loaded. Pre-load causes Figure D <br /> the cap to rotate downward in the <br /> direction of pull, further compacting the <br /> soil and presenting a larger surface <br /> area, resisting both horizontal and <br /> vertical movement. See Figure D. <br /> When used with rigid support tubes, <br /> rather than strap systems, pre-loading is <br /> not required. <br /> Note: A special adapter is available to insure against tension head and bolt damage 0 � <br /> Revised 3-14-07 7, <br />
