Its man approvals guarantees optimi ed load capacities for threaded rods and rebar. Its speciall developed chemical composition allows a reliable installation in underwater conditions and when lled in diamond cored drill holes. The low shrinkage of the mortar broadens the application spectrum in addition for big diameter fastener elements.

21 Installation instruction Anchor type: Installation Choose the right tools. Europ Control There is a clearl de ned set of tools for producing a safe xture: drilling machine, drill bit, hand-pump, brush, brush diameter gauge. See table Accessories Check availabilit of those s stem tools before starting. Drill hole to the re uired embedment depth with a hammer drill set in rotation-hammer mode using an appropriatel si ed carbide drill bit. for drill bit diameter and drill hole depth see table Anchor characteristics Working length of drill bit must be bigger than the given drill hole depth. Blow out at least 2x from the back of the bore hole until return air stream is free of noticeable dust. If the back of the bore hole is not reached an extension shall be used. The hand-pump can be used for anchor si es up to bore hole diameter 20 mm. For bore holes larger than 20 mm or deeper 240 mm, compressed air min. 6 bar must be used. Brush 2x with the speci ed brush si e b inserting the brush to the back of the hole in a twisting motion and removing it. If the back of the hole is not reached with the brush, a brush extension shall be used. The compressed air without oil. The brush must produce natural resistance as it enters the drill hole - if not, the brush is too small and must be replaced with the proper brush diameter use the brush diameter gauge. or Blow out at least 2x from the back of the bore hole until return air stream is free of noticeable dust. If the back of the bore hole is not reached an extension shall be used. The hand-pump can be used for anchor si es up to bore hole diameter 20 mm. For bore holes larger than 20 mm or deeper 240 mm, compressed air min. 6 bar must be used. Prior to inserting the anchor rod into the lled bore hole, the position of the embedment depth shall be marked on the anchor rods. Before use, verif that the anchor element is dr and free of oil and other contaminants. 114

22 Installation Tightl attach mixing no le to cartridge. Place the cartridge into dispensing gun. Do not modif the mixing no le. Control Onl use mixing no le and dispensing gun of the s stem. Discard initial adhesive. An initial amount of 10cm adhesive has to be discarded. Visual check if resin is evenl in colour. For ever working interruption longer than the recommended working time as well as for new cartridges, a new mixing no le shall be used. see table Working and cure times Inject the adhesive starting at the back of the hole, slowl withdrawing the mixer with each trigger pull. Fill holes approximatel 2/3 full, or as re uired to ensure that the annular gap between the anchor and the concrete is completel lled with adhesive along the embedment length. For embedment larger than 190mm an extension no le shall be used. For overhead and hori ontal installation in bore holes larger than 20mm a injection adapter and extension no le shall be used. Press the marked anchor element down to the bottom of the hole, turning it slightl while doing so. After inserting the anchor element, excess mortar must emerge from the annular gap. Marking the mixing no le makes it easier to ll ever hole with the same volume. If these re uirements excess mortar and the embedment depth are not maintained, the application has to be renewed. For overhead installation x embedded part e.g.wedges. Do not move or load the anchor until the mortar is full cured. see table Working and cure times After re uired curing time, the anchor element can be loaded. The applied installation tor ue shall not exceed. see table Anchor characteristic Check the max. tor ue b using a calibrated tor ue wrench. 115
