cm incremental layers. Each layer should be compacted with
light compaction devices (min. Dpr=95%). Damage to the tank
wall and displacement of the tank during and after installation
must be avoided. The self-actuating closure keeps the system
closed during the complete filling process.
G Connection of the tank
Any transport safety devices fitted must be removed. Note: the
pipe connection fittings must be protected against damage in
order to ensure the permanent integrity of the system. To make
connection easier, the pipe connection fittings should be ade-
quately greased.
The transition from downpipes to horizontal pipes must be
made using two 45° elbows separated by an intermediate pipe
at least 250 mm long. A calming section must be installed in
front of the separator system, which must be at least 10x as
long as the nominal width of the feed pipe.
G Connection of the sample removal shaft.
Sample removal devices must be installed in the direction
of flow immediately after the separator. The sample removal
device of the separator system must be freely accessible
and positioned so that only waste water is removed which
has passed through the separator.

G Insert the telescopic KESSEL upper section into the
opening of the separator and adjust to the required po-
sition. With the aid of the clamping ring, the upper sec-
tion can now be fixed in the required position (aligned
with the upper ground level). The fine adjustment to the
final height is then made with the aid of the setscrews.
Slopes can easily be compensated for by the fully height-
adjustable and inclining upper section. The upper section
must be adequately supported from underneath and vi-
brated in using a flat-bed vibrator and a steel plate laid
on the upper section.
For greater installation depths, the special KESSEL in-
termediate piece (Art. no. 917402), height 400 mm, in-
tended for this purpose should be used.

For installation in areas of heavy vehicle traffic (cover
class D), a reinforced concrete slab must be provided as
the upper layer. A corresponding formwork and reinfor-
cement plan is available from KESSEL.
In the case that the KESSEL SonicControl grease measurement
5.6 SonicControl Installation
system may be installed at a future date, a DN 40 (50mm outer
diameter) conduit pipe should be layed. A 60 mm diameter hole
should be drilled out at the location on the separator indicated
below.
The length of SonicControl cable between the separator and the
SonicControl control unit location should be kept as short as
possible as well as keeping the conduit as straight as possible
(no unnecessary bends over 45 degrees). This conduit should
have a continuous slope in the direction of the separator which
will let any moisture or condensation flow into the separator.
Condensation build up can be significantly reduced be providing
an air tight conduit connection on the control unit side. A pull
string or cable can be left in the conduit to ease the installation
of the SonicControl cable at a later date. The SonicControl cable
can be extended on-site but only to a maximum total length of
30 meters.
