Connecting the sand trap

If the planning stipulates that the RAUSIKKO C3 is to be
fitted with a sand trap, the excavation pit is to be excavated
deeper at the relevant place to accommodate the sand trap.
The sand trap is to be installed as follows:
1. Excavate the cavity for the sand
trap.
2. Create the bedding for the sand
trap.
3. Fit the seal on the upper end of
the sand trap. To do so, the upper-
most trough and the sealing ring
must be generously coated with
REHAU lubricant.
4. Fit the shaft adapter.
5. Put in place and align the sand trap with the shaft
adapter fitted.
6. Fill and compact the side area next to the sand trap.
7. Make the bedding for the connecting elements and the box
gravel trench.
8. Lay the geotextile filter/plastic liner sheet as given in the
installation instructions for the RAUSIKKO boxes, and cut out
a circular opening (diameter approx. 630 mm) in the area of
the sand trap. In case of retention, the plastic liner sheet must
be welded to the welding collar provided on the shaft adapter.
9. Fit the C3 shaft type 8.6X on the sand trap, and firmly
push-fit the shaft adapters already integrated in the floor.
