During interim storage of the separator and up to the end
of the installation work, suitable safety measures must be
taken on the construction site to avoid accidents and da-
mage to the light fluid separator.
The Chapter Safety Instructions must be observed!
5.1 Installation requirements
The installation must be carried only by companies who have
the necessary specialist experience, suitable equipment and
adequately trained personnel for the task.
The soil characteristics must be investigated for technical con-
struction suitability (soil classification for technical construction
purposes, DIN 18196). The maximum ground water level likely
to occur must also be established. The ground water level must
not exceed the level of the outlet. Adequate drainage of seepa-
ge water is also essential in the case of soils impermeable to
water. The types of stresses occurring, such as maximum traffic
loads and installation depth, must also be clarified.
The separators for ground installation should be installed out-
side the building, as near as possible to the outlets. If neces-
sary, the connection pipes of the inlets to the separator should
be laid with heat insulation, or heated. The required frost-free
installation depth is achieved by the use of telescopic attach-
ment pieces, which also allows easy adjustment to feed and
outlet pipes (drainage system). The covers for the load classes
A / B and D are not bolted and comply with EN 124.
5.2 Filling material
Substrate:
Crushed gravel (max. particle size 0/16)
Tank bed:
Sand
Tank jacketing:
Crushed gravel (max. particle size 0/16)
Area outside tank jacketing:Material with suitable properties
Covering layer:
Humus or similar
5.3 Construction pit
The foundation must be horizontal and level in order to be able
to set up the system over the full surface, and must also afford
adequate load-bearing capability. The substrate consists of
compacted crushed gravel (max. particle size 0/16, minimum
depth 30 cm, Dpr=95%), covered by 3 - 10 cm of compacted
sand. The spacing between the construction pit wall and the
tank must be at least 70 cm. The embankments must be con-
structed to DIN 4124. The depth of the construction pit should
be such that the limits of the earth covering are not exceeded.
MIN ≤ TEÜ ≤ MAX (see dimension drawing in the Chapter on
Technical Data).
Root penetration
In case of installation in the vicinity of trees or shrubbery, pe-
netration by roots must be reliably prevented.
Installation on a sloping site
In case of installation of the separator on a sloping site, care
must be taken to ensure that the laterally-acting soil pressure
of unsecured soil is absorbed by a suitably dimensioned sup-
porting wall.
Frost-free depth for all-year-round use
Always take care to observe the locally established frost-free
depth when installing the separator. In order to ensure the
smooth operation even in winter, the inlet and outlet pipes must
also be laid at a frost-free depth during installation.
5.4 Tests before installation
Immediately before installation of the tank in the construction
pit, the responsible specialist of the company carrying out the
installation must test and certify the following:
- the integrity of the tank wall;
- the proper condition of the construction pit, in particular with
regard to the dimensions and substrate bedding;
- the particle size of the filling material.
Please note:
Weather influences or cooling of the chamber during installation
(due to filling with cold water) could result in slight dimen-
