For reasons of safety, the length of the pipe and the number of
removable connections should be limited to a minimum. In
accordance with the safety regulations applicable in Germany,
a gas detector is required in every room in which there is a
removable gas pipe connection.

Once it has been laid, the complete pipework should undergo a
leakage test by a person with appropriate experience.
6.3.2 Ozone removal from filters and reaction section
A reaction tank may be required, depending on the use, to allow
the ozone to produce its full effect. The reaction tank guarantees a
sufficiently long reaction time of the ozone with the raw water. The
substances in the water are oxidised in the reaction tank.
In many cases, substances, such as dissolved residual ozone,
destabilised colloids, lumpy or coated micro-organisms and floccu‐
lated organic reaction products, may also have to be fully removed
from the water upstream of the discharge point. This can be done
using multi-layer filters, activated carbon filters or mixed bed filters.
Reaction tanks and/or filters must be provided with an effective
system for the extraction of residual ozone from the system. This
system must be ozone-resistant and should also be checked regu‐
larly to ensure that it is working correctly.
CAUTION!
The purified, ozone-free gas mixture must be
vented into the open air so that the oxygen does
not become concentrated in the installation room.
If the correct and proper operation of the removal
system cannot be guaranteed, there is a risk that
ozoniferous water may inadvertently pass through
the system at the discharge point. Maintenance in
accordance with the regulations is essential.
The pipework must be routed in such a way to ensure that no con‐
densate flows back into the residual ozone destruction unit.
WARNING!
During ozone destruction by activated carbon
destruction units, there is a risk of an explosion,
specifically with systems that generate high con‐
centrations of ozone gas, if the ozone accumulates
in the activated carbon layer. This means that
ozone destruction units, in which activated carbon
is used, are not suitable for these systems.
6.4 Assembly
The system is delivered standing vertically in a wooden crate and
should be positioned on a flat, even, horizontal and solid base sur‐
face.
