Composition of the chamber elements (see "Design", page 22).
The substrate (support for base section (technical module)) and filling material at the side of the chamber must have the fol-
lowing properties:
Blinding layer:
Layer of compacted crushed stone approx. 30 cm in height.
If required, fixing of the base section using lean concrete.
Filling material at the side: ring-shaped, all the way round approx. 50 cm, crushed stone (0-16mm), compacted every
30 cm .

When the chamber is installed inside a building, care must be taken that the structural requirements are fulfilled (see
"Taking the influence of foundation and floor slab into account", page 32).
Check chamber depth:
Make sure that the assembled chamber elements correspond to the depth of the excavation pit.
If a waterproof extension section (6) (see "Design", page 22) is to be used, make sure this is positioned at the prescribed
height.
The upper sections can be positioned in the waterproof extension section continuously height-adjustable by 25 cm.
If pressure pipes are required on site, they must be designed in accordance with PN 6.3.
If the pressure pipe is routed above the backwater level (see "Aquapump XL pumping station (for faecal wastewater, dry
installation)", page 24 and see "Ecolift XL", page 24), make sure that this can be operated frost-free.
Keep chamber elements and seals free of soiling.
The connections between the chamber elements
have been made, they can no longer be loosened. Upper sections can be dismantled at any time.
The chamber elements must be assembled from the bottom up.
The chamber system has been designed for a maximum of 0.3 bar water pressure.
4.2

Setting the base section

Dig out the excavations.
Pay attention to the slope angle of the excavations.
Align the base section horizontally in the excavations.
Slight deviations are noticed significantly right to the top of deep chambers.
The base section must be in contact with the subsoil across the whole of its surface.
Use lean concrete to fix the base section in place at the side ( see "Backfill the excavation pit", page 32).
Information for crane transport
Always use 4 load hooks.
Maximum load-bearing capacity of 4 load hooks: 200 kg.
Use a shackle with a 16 mm bolt diameter.
The crane chain or slip neck to the individual load point
must be at least 1 m long (A).
Do not leave loads suspended from the crane for longer
than one hour.
