Discharging the
backwashing water
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
For the backwashing water a wastewater
connection (for example a floor drainage) in
accordance with DIN 1986, or local equiva-
lent, must be in place. If there is no waste-
water connection an appropriately sized
bucket can be used.
The dimensioning depends on conditions on
site (e.g. wastewater pipe gradient, number
of pipe bends, length of the wastewater
pipe, etc.). If it is not possible to provide a
wastewater connection directly beneath the
filter, the flushing water can be fed several
meters to the next wastewater connection,
either through a hose or a pipe to be fitted to
the flushing water valve. This pipe must
have the same dimension as the flushing
water valve.
In all options, a free discharge must be
ensured in accordance with DIN EN 1717,
or local equivalent.
The following points must be noted if a
bucket is used for backwashing:
–
If the mains pressure is high, water can
splash out of the bucket. In this case,
damage to property close to the back-
wash protective filter is possible.
–
When the bucket is half-filled, the back-
washing process must be stopped.
Otherwise it is possible for the bucket to
overflow. Therefore the bucket must be
adequately dimensioned and the back-
washing should be carried out quickly.
