1 For your safety
Always read the safety instructions before installing and commissioning the plant in
order to prevent personal injuries and damage to property.
1.1 Intended use
1.1.1 Area of use
The plant serves to retain light liquids of mineral origin from the waste water. In areas where
the handling of light liquids with a mineral origin or mixtures of light liquids may endanger the
environment, separator plants for treatment or as retention devices must be provided.
Discharge into public sewerage or combined sewerage systems
The system can be used in the application areas listed below:
■Treatment of mineral oil-contaminated rainwater from paved
areas where mineral oil products containing up to 100% biodiesel and biofuel oil and/
or 10% ethanol are handled
Traffic areas (car parks and roads)
■Protection of plants and areas in or on which mineral oil products containing up to 100%
biodiesel and biofuel oil and/or up to 10% ethanol are handled (retention)
■Pre-separation of light liquids from wastewater which undergoes more stringent
treatment to limit hydrocarbons before being discharged into public sewerage systems
■Treatment of wastewater containing mineral oil (industrial wastewater), which is
produced under operating conditions similar to DIN 1999-1004, section 12.2 for
industrial processes, the cleaning of oil-contaminated parts and the cleaning of
oil-contaminated floor surfaces (workshop floors are only allowed after checking the
possibilities in individual cases)
In these cases, the treated discharge water from the plant is intended to be discharged into the
public sewerage or combined sewerage systems.
Discharge into water body
If the discharged water is to be discharged into a body of water, this is only possible in individual
cases after the permissibility of such a discharge or any additional requirements that may be
necessary have been claried with the local competent water authority.

For your safety
7/ 100
Oleolift-C
Special introduction
The use of the plants for the treatment of waste water arising from workshop drainage and from
the draining, dismantling, compaction and shredding of end-of-life vehicles is only possible in
specic cases after the permissibility of such a discharge has been claried with the competent
water authority, since in these cases other pollutants in addition to hydrocarbons may be
present in concentrations that cannot be adequately treated in a plant.
Wastewater treatment according to Annex 49 of the wastewater regulation
If the plant is used for the treatment of wastewater which contains mineral oil within the meaning
of Annex 49 of the Wastewater regulation, e.g.
■in mechanical vehicle cleaning (partial flow: discharge before the circulation system with
subsequent discharge),
■manual vehicle cleaning (vehicle washing, engine washing, underbody washing, chassis
cleaning in wash halls and at self-service or company washing stations),
■the drainage of areas which are to receive and store end-of-life vehicles, then it
constitutes a plant for the limitation of hydrocarbons in waste water containing mineral
oil within the meaning of Part E, paragraph 2 of Annex 49 of the Wastewater regulation.
In these cases, the value for hydrocarbons of ≤20 mg/l required under water law is deemed to
be complied with.
1.1.2 Application limits
■The maximum installation depth (distance between the upper edge of the manhole cover
and the tank base) is 7.00 m.
■When transferring wastewater into the public sewer system, the locally applicable
limiting value for hydrocarbons must be observed. Additional wastewater treatment may
be required. Suitable wastewater treatment plants on request, Introduction "ACO
Service".
1.1.3 Installation requirements
Only applies to Germany. Provisions in other countries can vary.
Protection against leakage of light liquids:
The light liquid must never be able to escape from the plant or from the shaft construction. The
installation is to be installed in such a way that the upper edge of the cover (earth's surface) is
arranged sufciently high in relation to the decisive level of the surface to be drained.
As the plant is equipped with an electrical warning system (suitable for operation in zone 0) for
light liquids, the plant does not need to be installed in an elevated position.

For your safety
8/ 100
Oleolift-C
Protection against backflow:
The required elevation must also be maintained with regard to the local backwater level of the
draining sewer system. In addition to the decisive level of the area to be drained on the inlet
side, the backwater level must also be considered as an additional decisive level for the required
elevation. The higher measure is to be applied for the excess height.
As the plant is equipped with an integrated pump station (double pump station according to DIN
EN 752 or DIN EN 12056-4) and is installed with a backow loop, the plant does not need to be
installed in an elevated position.
1.2 Improper use
Scope and changes
Applications and uses other than those described in chapter 1.1 and modications are not
permitted.
Non-approved parts
Installation of unapproved parts impairs safety and excludes any guarantee from ACO. In the
event of replacement, only use original ACO parts or spare parts approved by ACO.
Introduction
■No substances may be discharged into the plant which could impair the stability of the
materials used, the functional capability of the plant or compliance with the discharge
requirements into the downstream wastewater treatment plant or a water body (refer to
e.g. Series DWA-M 167). This includes in particular:
Faecal wastewater
Wastewater containing organic oils and greases
Wastewater in which a significant proportion of stable emulsions is present
Aggressive substances and cleaning agents containing chlorine
■Drainage of areas where light liquids do not accumulate, such as roofs and yards,
should not be discharged into separator systems
Entry into the plant
■The built-in fittings and components (e.g. separator inlet, coalescence insert) are
designed for operation as separators. They are not designed to be a step or foot board
for people and storage e.g. heavy cleaning devices. The bearing force is not designed
for such purposes.
■The use of an access aid for accessing or entering the plant is anchored in the
requirements of the employers' liability insurance association.

For your safety

1.3 Fundamental hazard potential
The plant is dened as a Zone 0 hazardous area.
■Access to the plant is only permitted when the accident prevention regulations valid
at the time of access are taken into account. Accident prevention regulations can be
obtained from your local accident insurance association.
■Never descend into the plant without breathing apparatus and/or without prior testing of
the gas concentration and without safety equipment (refer to the responsible accident
prevention regulations).
■Work on electrical system parts may therefore only be carried out by qualified
personnel.
1.4 Normative specifications
The installation and operation of the plant is subject to the local authority regulations. For more
information, please contact the responsible authorities. The following standards are listed for
orientation purposes and must be supplemented and checked to ensure that they are up-to-date
(only applies for Germany. Provisions in other countries can vary).
