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 arro-
ws 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 indivi-
dual layers of the backfilling material should not exceed a
height of 30 cm. They must be compacted using light com-

Area outside tank encasing: material of suitable
consistence
Top layer: topsoil, road surface, concrete or similar
pacting equipment (minimum Dpr=95%). Damage to the
tank wall and a dislocation of the tanks during and after in-
stallation must be ruled out.

4.7 Pipework

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 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
KESSEL cover (cable conduit sealing, item No. 97711)
should be installed as protection against unpleasant odours.
