Area outside tank encasing: material of suitable<br />
consistence<br />
Top layer: topsoil, road surface, concrete or similar<br />
4.4 Placing<br />
The tank must be placed shock-free into the excavation pit<br />
with the aid of suitable equipment and put down onto the<br />
base bedding (see also chapter "Transport").<br />
Pay attention to direction of flow and direction of flow arrows<br />
on the tank!<br />
4.5 Filling the tank<br />
Fill tanks in both chambers with clear water (approx. 80 cm)<br />
to achieve an improved stability.<br />
4.6 Backfilling the excavation pit<br />
In general, filling the tank and backfilling the excavation pit<br />
should be carried out in parallel. The excavation pit is backfilled<br />
up to the bottom edge of inlet and drain, as well as the<br />
ventilation line and cable conduit line. The tank encasing<br />
must be produced in a width of at least 50 cm. The individual<br />
layers of the backfilling material should not exceed a<br />
height of 30 cm. They must be compacted using light compacting<br />
equipment (minimum Dpr=95%). Damage to the<br />
tank wall and a dislocation of the tanks during and after installation<br />
must be ruled out.<br />
4.7 Pipework<br />
The inlet/drain lines as well as connecting lines must be laid<br />
in a frost-free manner (see 4.2) and connected as soon as<br />
the excavation pit has been backfilled and compacted up to<br />
the bottom edge of inlet and drain line.<br />
The transition from penstocks to horizontal lines must be<br />
executed with two 45° curved fittings and an at least 250<br />
mm long connecting piece. A stilling section, the length of<br />
which corresponds to at least the tenfold of the pipeline's<br />
nominal width, must be provided upstream of the <strong>INNO</strong>-<br />
CLEAN ® tank.<br />
A cable conduit (KG pipe made of PVC-U in the dimension<br />
DN 100) must be laid as line link between control unit/ compressor<br />
and valve block /<strong>INNO</strong>-CLEAN ® tank. The empty<br />
conduit should exhibit a constant gradient of ≥ 2° in relation<br />
to the tank along its entire length. <strong>KESSEL</strong> recommends to<br />
execute the duct through the building wall in the manner of<br />
wall ducts customary in trade (see illustration).<br />
In order to seal the cable conduit inside the building the<br />
<strong>KESSEL</strong> cover (cable conduit sealing, item No. 97711)<br />
should be installed as protection against unpleasant odours.<br />
