6.4 Connecting the emergency overflow
The
SMT-F-SC
has an emergency overflow line (DN 50)
which must be connected to the waste drainage system of
the building. The drainage line must be of a size to
accommodate a maximum volume flow rate of 90 l/min.
Note:
The position of the backwater level must be taken into
consideration while connecting to a drainage system, in
order to prevent backflow of drainage water from the open
sewer line (design according to the DIN EN 1717) entering
the
SMT-F-SC
.
The position of the backwater level determines the type of
line:
a) Backwater level
above
the emergency overflow
drainage height of the separation chamber:
Connection of the emergency overflow must be
done by a lifting system.
b) Backwater level
below
the emergency overflow
drainage height of the separation chamber:
Connection of the emergency overflow to a
ventilated channel line (DN 50) is done via a siphon.
