4.5 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 materials 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.
4.6 Install the upper section
Insert the lip seal into the opening.
Grease the surface with contact with the upper section (sealing lip).
Determine the required installation height above ground level. Insert the vertically adjustable upper section provisionally,
and fix it with a clamping ring. The clamping ring may lie against the lip seal on the outside.
Check whether the required free space to the inlet or outlet structure of at least 200mm (see figure below) is guaranteed.
If not, dismantle and shorten the upper section; note the minimum insertion depth of the upper section. If the upper sec-
tion has been shortened, chamfer the end of the upper section (15°, 200mm).
Re-install the upper section if necessary.
Fit the cover plate.
Turn the cover lock to „N" (NEUTRAL).
Align the cover lug.
Lock the cover plate (CLOSED).
If a layer thickness measuring device for grease and light liquids is to be installed, fit the bracket as described in the
enclosed instructions.
