Tank encasing: round-grain gravel (max. graining 8/16)

4.4 Placing

The tank must be placed shock-free into the excavation pit
with the aid of suitable equipment and put down onto the
base bedding (see also chapter "Transport").
Pay attention to direction of flow and direction of flow arrows
on the tank!

4.5 Filling the tank

Fill tanks in both chambers with clear water (approx. 80 cm)
to achieve an improved stability.

4.6 Backfilling the excavation pit

In general, filling the tank and backfilling the excavation pit
should be carried out in parallel. The excavation pit is back-
filled up to the bottom edge of inlet and drain, as well as the
ventilation line and cable conduit line. The tank encasing
must be produced in a width of at least 50 cm. The individu-
al layers of the backfilling material should not exceed a height
of 30 cm. They must be compacted using light compacting

Area outside tank encasing: material of suitable

Top layer: topsoil, road surface, concrete or similar
equipment (minimum Dpr=95%). Damage to the tank wall
and a dislocation of the tanks during and after installation
must be ruled out.

4.7 Pipework

A Pipe installation example is available on pages 224-227.The
inlet/drain lines as well as connecting lines must be laid in a
frost-free manner (see 4.2) and connected as soon as the ex-
cavation pit has been backfilled and compacted up to the bot-
tom edge of inlet and drain line.
The transition from penstocks to horizontal lines must be
executed with two 45° curved fittings and an at least 250 mm
long connecting piece. A stilling section, the length of which
corresponds to at least the tenfold of the pipeline's nominal
width, must be provided upstream of the INNO-CLEAN
tank.
A cable conduit (KG pipe made of PVC-U in the dimension
DN 100) must be laid as line link between control unit/ com-
pressor and valve block /INNO-CLEAN
conduit should exhibit a constant gradient of ≥ 2° in relation
to the tank along its entire length. KESSEL recommends to
execute the duct through the building wall in the manner of
wall ducts customary in trade (see illustration).
In order to seal the cable conduit inside the building the
