•
The tanks are offset at the appropriate height and watertight.
•
A watertightnesss test has been carried out and concluded successfully. For this, the
installation instructions of the tank manufacturer are to be observed.
•
All chambers of the plant are accessible to persons (clear openings of at least 600mm
diameter).
•
A fully functioning aeration and ventilation of the plant must be assured. In normal cases this
takes place via the roof ventilation and a cover with ventilation openings in the (last) tank or
ventilation in the run-off pipe. The correct operation is to be documented and verified.
•
The run-off pipeline is connected to the manhole and reaches ca. 15 cm into the shaft (do not
cut off at the manhole wall).
•
Behind the wastewater treatment plant is located a further distributor, control or percolation
shaft. If this is not the case then a possibility for sampling is to be installed in the SBR tank.
•
Should the buffer tank be divided into several chambers, then the partition wall must have
openings at the bottom.
•
A 230 V power line is laid to the location of the control unit and is fused separately as follows:
B 16 A, and 25 A / 30 mA earth leakage circuit breaker (ELCB).
•
Between the control unit and the wastewater treatment plant there are laid one (buffer and
SBR in one tank) or two (buffer and SBR in separate tanks) cable conduits ( ≥ DN 100). There
may be no bends laid with a greater curvature angle than 30°! The cable conduits are to be
sealed odour-tight.
•
Pull wires are included in the conduits. The maximum distance between control system and
AQUA
max
®
or buffer for the ready-to-plug variants is 35 m (for plants with compressor aeration
[GZB] 12 m).
•
The tank is free of wastewater and cleaned.
•
The AQUA
max
®
incl. accessories are on the construction site at the start of assembly.
•
The inlet pipeline is connected to the primary settling stage. With retrofitting this, as a rule, has
been laid (if necessary please take note of the project sketch).
•
The connection pipeline between primary settling stage, buffer and aeration stage is carried out
in DN 150. There may be no bend laid with a greater curvature angle than 45°.
