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 backfilled
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 individual
layers of the backfilling material should not exceed a height
of 30 cm. They must be compacted using light compacting
4. Installation and assembly
Subbase: round-grain gravel (max. graining 8/16) according
to DIN 4226-1 compacted with Dpr=95%
Tank bed: compacted sand

Area outside tank encasing: material of suitable
consistence
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 268-271.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 excavation
pit has been backfilled and compacted up to the bottom
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 InnoClean PLUS
tank. To prepare the inlet on-site the inlet pipe should be
pushed approx 20 cm into the inlet opening. The outlet pipe
can be connected to the main drainage pipe using a pipe
connector.
A cable conduit (KG pipe made of PVC-U in the dimension
DN 100) must be laid as line link between control unit/ compressor
and valve block /InnoClean PLUS tank. The empty
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
