About this system
The Legio Zon® chlorine dioxide production and dosing system is designed for potable water
treatment, particularly to combat Legionella.
The controller feeds the required amount of dilution water to the reactor and mixes it with precisely
calculated amounts of hydrochloric acid and sodium chlorite that are dosed via two dosing pumps.
A ClO2 solution with a concentration of 2 g/l is produced. This low concentration – compared with
other processes – minimises the potential dangers.
The prepared ClO2 solution is transferred to a storage tank from which it is dosed with the dosing
pump, also integrated in the system.
The combination of dosing monitors, level switches and time monitors ensures reliable operation.

Description and test of the safety devices
Chlorine dioxide systems Legio Zon® are designed and built in accordance with the German Gas
and Water Authority DVGW technical standards W 224 and W 624. They have the following
safety devices:
Dosing monitoring devices
The pumps must always dose the chemical components in the correct ratio. If too much acid is
dosed, the treated water will be too acidic, which can lead to corrosion damage. If too much
chlorite is dosed, the treated water will contain chlorite (limits!).
Two different devices prevent this:
The suction lances in the component containers are equipped with two-stage level switches.
The level switches are designed to prevent only one component being dosed on its own. At the
first level, the controller shows a warning message on the LCD display and the “Warning” relay
operates. At the second level, the control still allows reaction batch that has been started to be
completed. The control shuts down the system before the next batch. A message appears and
the "Alarm" relay switches.

Safety section / Storage and transport
Dosing monitors
The dosing monitors are intended to indicate an uncontrolled change in the dosing ratio of the
components. For this, a dosing monitor is positioned after each pump. The magnetic float in the
dosing monitor bobs up and down in time with the pressure surges of the dosing medium of the
pump. The controller records this via the proximity switch of the dosing monitor. If these signals
fail, the controller switches the dosing off and gives an alarm: the “Alarm” relay operates and a
message appears in the LCD display.
The position of the proximity switch is accurately set in the factory and must not be adjusted!
Safety bunds (accessory)
The safety bunds are intended to prevent uncontrolled escape of the chemical from a faulty
component container and to prevent the chemical possibly mixing with the other components.
3
Storage and transport
The chlorine dioxide system Legio Zon® CDLa is supplied in a wooden crate. The chlorine dioxide
system must be drained before being stored or transported.

Functional description
Chemical principle of the system
The chlorine dioxide system Legio Zon® CDLa works according to the hydrochloric acid-chlorite
process:
hydrochloric acid + sodium chlorite = chlorine dioxide + sodium chloride + water
4HCl + 5NaClO2 = 4ClO2 + 5NaCl + 2H2O
By bringing together dilute hydrochloric acid, dilute sodium chlorite solution and water, the
Legio Zon® system initially produces a 0.2 % chlorine dioxide solution (2 g/l). This solution is
stored in the system in the interim and fed to the water being treated at the required rate.
Operating principle of the system
Two dosing pumps dose the components – Bello Zon® acid and Bello Zon® chlorite – into the
reactor, which is pre-filled with a defined quantity of water. After a defined reaction time has
elapsed, the controller drains the contents of the reactor into the storage tank. The third dosing
pump doses this ClO2 solution. Dosing is controlled at the required rate by the signal from a
water meter.
In the "without metering pump" version, the system is equipped with two separate metering
pumps instead of the integrated CIO2 pump. They are to be configured for activation via external
control regulators. The integrated CDLa controller is not used in this case.
Safety devices
The safety devices are described in Sect. 2.6.

Installation position requirements / Mounting
The following information on acid capacity refers to a CIO2 dosing concentration of 0.4 ppm. They
are suggested figures that must be checked on site by pH measurements in continuous operation.
The information given should prevent pipeline corrosion by maintaining the pH above 6.5.
If the water to be treated has an acid capacity up to pH 4.3 (KA4.3) of less than 0.4 mmol/l and a
carbonate hardness of less than 1.1 °dH, a pH increaser must be dosed in addition. For this,
a Beta or gamma/ L type dosing pump can be controlled in parallel with the ClO2 dosing pump
(refer to terminal connection diagram in the Appendix).
CAUTION
Take account of possible consumption of ClO2 by the water components and ensure that
the required ClO2 concentration is also actually reached! At the same time, bear in mind
the simultaneous formation of chlorine.
7
Mounting
CAUTION
• The system must be easily accessible for maintenance work!
• The dosing line must not be exposed to strong light!
Otherwise the light decomposes the ClO2 !
• Observe the applicable national and local rules and regulations!
The supplementary kit supplied includes the necessary bolts, wall plugs and shims
(supplementary kit = bag of bolts etc.).

Install a dirt trap first to protect the system and valves.
8.1.2
System isolator
WARNING
The pipeline carrying the water to be treated must never come under vacuum!
Otherwise uncontrolled siphoning of the ClO2 solution can occur, so provide a system
isolator!
8.1.3
Water meter
WARNING
• There must be no possibility of water extraction between the water meter and the
dosing point!
Otherwise the ClO2 concentration at the dosing point can increase sharply leading to
health problems! What's more, the pipes can corrode!
• Maintain the inlet and outlet distances upstream and downstream of the water meter in
accordance with its operating instructions!
Otherwise the ClO2 concentration in the treated water could turn out to be wrong
because of incorrect readings!
The controller of the Legio Zon® system can process signals from the following types of
water meter:
a)
b)
c)
d)
Magnetic inductive water meter (IDM) with frequency output
Contact water meter with Hall-effect sensor
Contact water meter with reed switch contacts
Contact water meter with inductive pulse transmitter (Namur)
ATTENTION
Avoid problems with the water meter.
Use an IDM type if at all possible (magnetic inductive water meter).
The water meter should be installed after the system isolator and before the dosing point
(see Fig. 8). It must measure the total volume of water that is to be treated!
To ensure continuous dosing of the ClO2 solution, contact water meters must be selected in
accordance with the following table:

Table 1: Maximum adjustable ClO2 setpoints in relation to the water meter pulse interval
To avoid corrosion due to occasional overdosing of acidic chlorine dioxide solution, the controller
only accepts target ClO2 concentrations up to a certain maximum setpoint. This depends on
the pulse interval set on the water meter. As a result, the controller only permits a maximum of
2 dosing strokes of the chlorine dioxide pump per incoming pulse from the water meter.
For suitable applications, you can cancel this limitation in the setting menu under “Cancel corrosion
protection”.

8.1.4
Dosing point
WARNING
• Install the ClO2 connection of the dosing point vertically downwards!
Otherwise the integral non-return valve can’t close!
• PTFE hose (e.g. 6x4 mm, Order No. 37426 or equivalent) must be used for the feed line.
Other materials such as polyethylene (PE) are not sufficiently resistant to CIO2 and
would therefore result in leaks
• The pipeline from the Legio Zon® system to the dosing point must not be exposed to
bright light!
The light can decompose the ClO2 which means that the water can't be adequately
treated!
• If an electrically conducting pipe is broken into as part of the installation, suitable
equipotential bonding must be provided (e.g. link the two ends of the pipe with a metal
bridge)!
Otherwise there can be grave danger to personnel and to equipment during a lightning
strike, for example!
• The dosing point must always be leak-free! So it must be corrosion-proof too!
Otherwise uncontrolled siphoning of the ClO2 solution can result!
• Bear in mind the temperature-dependence of the maximum permissible pressure of the
dosing point used!
Install the dosing point at a suitable point in the main water pipe (for minimum corrosion and
optimal mixing) e.g. dosing point Legio Zon® CDL:

depends on the pulse interval set on the water meter. As a result, the controller only permits a
maximum of 2 dosing strokes of the chlorine dioxide pump per incoming pulse from the water
meter.
For suitable applications, you can cancel this limitation in the setting menu under “Cancel corrosion

Manual dosing
In “Pause, an open contact causes the ClO2 dosing to be interrupted – otherwise the system
carries on working normally.
In ”Shock dosing”, a separate contact signal (close) causes the ClO2 pump to run at maximum
stroke frequency – for a number of strokes that can be set here.
In “Boost dosing”, a closed contact causes the system – controlled by the water meter – to dose
a higher target concentration of ClO2 . The higher target concentration is set here.
In “Manual dosing”, a closed contact causes the ClO2 pump to run at a stroke frequency that can
be set here.
The alternating displays show these operating modes in plain text.

왘 Take the PVC hose off the 3-way valve and fit the plug
왘 Set the 3-way valve to “Operation”
왘 Empty the 10 l bucket down the drain and flush again with liberal amounts of water.
All the pumps are now vented.
왘 Press ENTER to start the commissioning – the controller fills the reactor with dilution water and
the pumps then pump acid and chlorite into it.
The controller then allows the prepared mixture to flow through the solenoid valve into the
storage tank.
It then refills the reactor with dilution water and the pumps pump acid and chlorite into it.
In the next menu item, the controller displays the “Remaining reaction time” of the mixture
in the storage tank. Once this time has elapsed (standard: 20 min), the ClO2 solution is ready.
The “ACTIVE” message appears in the alternating display and the system starts dosing.
WARNING
• The ClO2 concentration in the treated water can be reduced too sharply due to
consumption!
• So check the ClO2 value in the treated water, correct as necessary, and enter this in the
commissioning log after the Legio Zon® system has been dosing for a certain time!
CAUTION
• Too low a pH in the treated water can lead to corrosion damage in the entire installation!
• So check the pH in the treated water, correct as necessary, and enter this in the
commissioning log after the Legio Zon® system has been dosing for a certain time!
With pH values below 6.5, provide additional dosing with a pH increaser!

Operation
11.1
Replace component container
WARNING
• Only instructed personnel must replace the component containers!
Large quantities of toxic ClO2 gas can be produced as a result of improper handling!
• Observe the colour code!
Red stands for acid (HCl, large component container, on the left),
blue stands for chlorite (NaClO2 , small component container, on the right)!
• Never pour chemicals from the component containers back or pour them together!
Large quantities of toxic ClO2 gas can be produced!
• Never put both suction lances in the same container!
Toxic ClO2 gas can be produced!
• The two components – hydrochloric acid (HCl) and sodium chlorite (NaClO2 ) must never
come together, other than in the reactor!
Otherwise toxic ClO2 gas can suddenly be formed, which can decompose explosively!
• Ensure that the “acid” suction lance is fitted in the container for the “acid” component
(observe coloured labels!) and that the “chlorite” suction lance is fitted in the container
for the “chlorite” component.
• Never operate the Legio Zon® CDLa chlorine dioxide system with undiluted sodium
chlorite! Otherwise it can result in ClO2 concentrations that the system is not designed
for! Only use Bello Zon® chlorite!
• Never operate the Legio Zon® CDLa chlorine dioxide system with undiluted sodium
chlorite! Otherwise it can lead to chlorite concentrations in the treated water that are
harmful to health! Only use Bello Zon® chlorite!
• Never confuse sodium chlorite (NaClO2 ) with sodium hypochlorite (NaOCl)! Only use
Bello Zon® chlorite!
• Only use Bello Zon® acid!
• Do not use any technically contaminated hydrochloric acid.
It can contain chloroorganic compounds that will attack the seals aggressively and
cause embrittlement of the PVC components!
왘 The LCD screen must be showing OFF – press the “Start/Stop” key if necessary
왘 Carefully take each suction lance out of its component container (lift it slowly and keep it
vertical)
왘 Put each of the suction lances into a bucket filled with clean water (this prevents the suction
lances from emptying)
왘 Close the empty component containers and have them disposed of professionally.
왘 Position the new component containers under the system (acid = large, red, on the left;
chlorite = small, blue, on the right!)
왘 Screw the cap with the correct suction lance on to the component container (Observe colour
code! The cap on the suction lance for acid cannot be pushed down or screwed onto the
component container for chlorite!)
왘 Check the suction lances for air bubbles; if there are any, flush the system (se below)
왘 Press the “Start/Stop” key to start the dosing.

The protocol function records all important events on the controller of the Legio Zon® system
(see Table 5) and retains the information even after a mains failure. It numbers the events
consecutively and retains the time of the event (the internal clock keeps running during
a mains failure).
The protocol function starts with the initial commissioning in the factory.
The controller counts the time “t” of new events starting from the last reset of the operating time
(this is normally the date of the last maintenance).
The controller continues to store old events when the operating time is reset.
They retain their old time “t”.
You can scroll through the protocol with the arrow keys.

Taking out of service
WARNING
• Never combine the contents of the component contents! A large quantity of toxic,
explosive ClO2 gas is then produced!
• Never put both suction lances into the same bucket either together or one after the
other! A large quantity of toxic, explosive ClO2 gas is then produced!
• Do not adjust the different valves! Corrosive chemicals can escape!
15.1
For a short period
To take the Legio Zon® system out of service for a short period only, simply press the “Start/Stop”
key (“OFF” appears). The power supply to the controller of the system must not be switched off.
The power supply to any chlorine dioxide or chlorite measurement point installed must not be
interrupted for longer than 2 hours!

Leaflet: “Hazardous Material Data Sheet Chlorine Dioxide: Properties of chlorine dioxide
and notes on handling aqueous solutions”
Hazardous materials data sheet, chlorine dioxide
Characteristics of chlorine dioxide and notes for handling
with aqueous solutions
The chlorine dioxide base solutions used in the treatment of water have a concentration of 2 g/l
CIO2. A temperature of up to 25 °C results in a chlorine dioxide concentration in the gas space of
less than 100 g/m3. Thus appropriate preparation in both gas space and base solution eliminates
an explosive disintegration.
1.
Physical and chemical characteristics

1.2
Characteristics of chlorine dioxide gas

Melting point:
Boiling point:
Stability:
orange/yellow
pungent
- 59 °C
11°C
chlorine dioxide gas disintegrates explosively in concentrations
from 300 g/m3 (^
= 10 Vol%) in chloride and oxygen.
Diluting reduces explosibility; the risk of explosion is eliminated where
concentrations are less than 10 Vol% in gases, with which chlorine
dioxide does not react (e.g. air, nitrogen, carbon dioxide).
With a critical concentration of chlorine dioxide, for example in gas
space above an aqueous chlorine dioxide solution, a chlorine dioxide
concentration greater than 8 g/l (at a temperature of 20 °C) must be
used.
An extreme, or even explosive reaction similarly occurs with oxidisable
substances.
1.3
Characteristics of chlorine dioxide aqueous solutions
The gas is critical.

Stability:
With no gas space, aqueous chlorine dioxide solutions are
explosive from a concentration of around 30g/l, i.e. they can
disintegrate explosively by themselves, without the impact of external
factors such as heat, sparking, dirt or rust.
Chorine dioxide is stable for several days in the form of an aqueous
diluted solution, as long as the solution is pure and is stored in a dark
place or as long as the temperature of the solution remains below
25°C and has a pH value less than 7.
2.
Handling with aqueous chlorine dioxide solutions
2.1
Identification and notices
Workstation and work areas are identified via notices in compliance with the accident prevention regulations
”Chlorination of water” (GUV 8.15, appendix 3)
2.2
Storage
Due to the danger of explosion, chlorine dioxide cannot be stored or transported either as a gas or as a
concentrated aqueous solution. Hence it is only produced as a diluted (see section 1.3) aqueous solution in
special equipment for immediate use.
2.3
Measures for filling, leaking, gas emissions
Condense gas by spraying with water.
Pour sodium thiosulphate solution onto any solution that has leaked, then dilute with plenty of water and
rinse down the drain.
2.4
Actions in the event of fire
Chlorine dioxide itself is not flammable but can be combustible. Explosive disintegration at temperatures
from 100°C. Cool containers with water, condense leaked chlorine dioxide gas by spraying with water.
There is no restriction on fire extinguishing substances in areas where there is a fire hazard.
2.5
Disposal
See section 2.3
3.
Health protection
3.1
MAK value and odour threshold
0.1 ppm (ml/m3) or 0.3 mg/m3
MAK value:
Odour threshold the odour of chlorine dioxide gas can be detected in air in concentrations from
around 15 mg/m3.

Health hazards
A concentration of chlorine dioxide gas exceeding 45 mg ClO2 /m3 causes breathing difficulties and leads to
irritation of mucous membranes and headaches.
Generally chlorine dioxide causes severe reactions in mucous membranes pertaining to the eyes and
respiratory organs. Depending on the concentration and duration of exposure it can lead to a danger of
suffocation, coughing fits, vomiting, burning onto the skin and severe headaches, and in serious cases to
pulmonary oedema with breathing difficulties, oxygen deficiency and circulatory collapse. With brief
exposure to very high concentrations there is a risk that the person stops breathing or suffers glottal spasm
or cardiac arrest. Damaging to the nerves (e.g. paralysis of the eye muscles).
3.4
First aid
You should immediately remove any clothing that has come into contact with chlorine dioxide or respective
aqueous solution and wash the skin thoroughly with soap and plenty of water.
Rinse the eyes well for several minutes under running water, ensuring the eye is opened as widely as
possible.
After inhaling chlorine dioxide, fresh air, lie down, keep still and keep warm.
Notify the doctor immediately, even if symptoms do not appear immediately. If necessary, smooth, fast
transport to hospital.
