2. Installation conditions
2.1. Installation basics

Existing drainpipes should be checked for matching connection heights.

The materials of the inlet and outlet pipes must be resistant to wastewater light fluids
containing petroleum.

The required pipe diameter, depending on the nominal size of the separator and the
required slope of the line according to the corresponding standards (EN 752-4, EN
12056-2, EN 858-1), must be adhered to.

Safety against buoyancy and flotation must be ensured.

The installation instructions for the tank must be followed.

A sampling option should be provided.

Proper ventilation of the inlet and outlet pipes (according to EN 1825).

The condition of all components must be checked before installation and protected
from damage or dirt.

The covers must be marked with "separator" and the load class for the covers in
accordance with EN 124:1994. The use of interlocking or ventilating covers is not
allowed.
2.2. Requirements for the installation site

The installation site must be frost-protected.

The installation site should be as close as possible to the wastewater accumulation
location.

The accessibility of the inlet and outlet area for cleaning vehicles and for inspection
must be ensured (alignment of the shaft structures).

The excavation base must be installed horizontally and must have sufficient base
course / bearing capacity.

The inlet and outlet lines must be installed in compliance with EN 12056 and EN 858-
2.

Separators are to be operated without backflow by gravity.
below the locally specified backflow level are to be connected to the drainage system
according to EN 12050 by means of sewage lifting units.

Before filling the building pit, and possibly before connecting the inlet and outlet line,
the system including shaft structure should be checked for leaks. Procedures and
results of the inspection should be documented.

Special local requirements must be taken into account (e.g. water protection area,
flood prone areas etc.).
