Positioning and connecting the tank
Position and align the tank as described in the transport
instruction.
Connect the inlet and outlet lines and connect them to the
on-site piping.
Install the lip seal, upper section and cover plate to
ensure protection during the construction period. Ensure
that the upper section is level with the planned ground
level.
Wastewater pipes and fittings made of the following materi-
als may be connected to the inlet and outlet of the separator:
Polyvinyl chloride (PVC-U)
Polyethylene (PE)
Polypropylene (PP)
The following technical instructions must be followed:
The inlet and outlet must be laid with gravity flow.
The inlet and outlet pipes must be laid at a frost-free
depth.
The inlet pipe must be connected to the downpipe with
two 45° bends. A stilling section with length equal to
approx. ten times the diameter of the inlet pipe must be
included in the design.
The inlet pipe must be routed additionally above the roof
as a ventilation pipe. If the inlet pipe is laid over more
than 10 m (horizontally), a further ventilation pipe must be
attached near the separator.
Do not make any additional connections to the tank.
Perform a leak test on the connections before backfilling
the excavations.
