English INSTALLATION
3. Using a colored line, mark the center of the individual disc aerators on the bottom of the
basin and measure the boreholes for the base supports of the aerator pipes.
The boreholes of the base supports must be precisely on the marking line and match
the supplied drilling plan, since there can otherwise be twisting during installation.
4. Before you begin drilling the holes, check the distances of the aerator group to the
basin wall. The distances must match the design, since the calculated air inclusion can
otherwise not be ensured.

• The drop-in anchor may only be used in reinforced or unreinforced normal concrete with
a strength class between C20/25 and C50/60 (according to EN 206:2000-12).
• The drop-in anchor is only suitable for crack-free concrete.
• Before the drop-in anchors are used, the strength of the structure must be ascertained
in order to ensure that the reaction forces can be absorbed.
1. Drill the individual holes for the corresponding base supports. Use a drill with a borehole
depth marking.
2. Thoroughly clean the boreholes, such as by vacuuming them out.
3. Place the drop-in anchor into the borehole and carefully drive it into the hole using a
rubber mallet. The anchor and foundation must be flush with each other.
4. Rotate the threaded rods completely into the anchor.
5. Twist on two hexagon nuts per anchor rod, place one flat washer on each, and attach a
pipe clamp with the bend pointing downwards.
