INSTALLATION English
3 Flat washer 7 Elastic band for securing pipe
4 Hexagon nut for attachment 8 PVC adhesive
• The anchor bolt 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 anchor bolt is only suitable for crack-free concrete.
• Before the anchor bolts 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 anchor bolt into the borehole and carefully use a rubber mallet to drive it into
the hole until it reaches the insertion depth marking. The threaded rod for securing the
components must protrude out of the foundation.
4. Place the foot of the base support onto the threaded rod and secure it with the washer
and hexagon nut.
Important: When tightening the hexagon nuts, make sure that the foot doesn’t
break.
5. Turn the upper part of the base support with the pipe support onto the foot.
5.4.4. Aligning the contact surface for the pipes
In order to ensure proper aeration, the individual aerator groups must be aligned so that
they are precisely horizontal and all aerator groups are the same height. The recom
-
mended distance between bottom of the basin and the pipe support is 70 mm. Within
an aerator group, a deviation of no more than ±10 mm is permitted. The height of each
support can be adjusted between 70 mm and 100 mm. The precise height can be mea
-
sured and adjusted using a leveling device (laser).
When carrying out leveling work, also keep in mind the height of the air distributor.
The air distributor must be connected to the intake line so that it is free of strain.
Height adjustment of the stainless steel base support with drop-in anchor and
threaded rod
The height is adjusted using the two hexagon nuts. The top hexagon nut is used to set
the desired height, and the bottom nut is used to secure the adjustment (locknut).
Height adjustment of the PVC base support with anchor bolt
The height is adjusted by turning the pipe support. If this height adjustment is not
sufficient, an extension can be installed.
1. Rotate the extension onto the foot and secure the connection using PVC adhesive.
2. Rotate the upper part of the support onto the extension and set the desired height.
