2 Safety
2.1 General warnings
The following warnings are intended to help you eliminate the dangers
that can arise while handling the device. Risk prevention measures
always apply regardless of any specific action.
Safety instructions warning against risks arising from specific activities
or situations can be found in the respective sub-chapters.
DANGER!
Danger to life from chlorine poisoning!
Chlorine is poisonous. In severe cases, breathing in chlorine may lead
to death. It irritates the eyes, the respiratory system and the skin.
ðInstall a gas warning device.
ðUse sufficient personal protective equipment.
ðWhen carrying out any work on the system, use a respirator mask
with a Type B gas filter that complies with EN 14387.
ðAlways comply with the accident prevention regulations that apply
at the place of use.
ðGet rid of leaks without delay. You must get rid of even very minor
leaks without delay. Together with the humidity, chlorine forms
hydrochloric acid and corrosion results in rapidly increasing
leakage.
ðUse only chlorine-resistant seals.
ðOnly use seals once. Reusing them leads to leaks.
DANGER!
Increased danger to life from chlorine escape
A fatal quantity of chlorine gas can be released from a leakage.
ðIf chlorine escapes, leave the room immediately.
ðUse sufficient personal protective equipment.
ðIf chlorine gas escapes, wear a Type 2 self-contained breathing
apparatus that complies with EN 137.
ðOnly initiate counter measures after putting on the protective
equipment.
ðGiven a serious escape and insufficient equipment or qualifica-
tions, leave the work to professional emergency services
personnel. Do not take any unnecessary risks.
DANGER!
Danger to life through explosions!
When using dosing devices without ATEX certification in a potentially
explosive area, explosions can occur that result in fatal injuries.
ðNever use the device in potentially explosive areas.
WARNING!!
Increased risk of accidents due to insufficient qualifica-
tion of personnel!
Chlorinators and their accessories must only be installed, operated
and maintained by personnel with sufficient qualifications. Insufficient
qualification will increase the risk of accidents.
ðEnsure that all action is taken only by personnel with sufficient and
corresponding qualifications.
ðPrevent access to the system for unauthorised persons.
Note
Damage to the system due to corrosion
Chlorine gas is highly hygroscopic. This means that humidity enters
the system at any open connection on devices or pipes, which results
in the formation of hydrochloric acid and contamination. thus
inevitably causing damage to the units.
ðKeep all connections (including in the vacuum system and on all
devices not currently in use) closed at all times.
ðAfter maintenance work is complete, remove all water residues
from the system before placing it into operation.
2.2 Information about chlorine
Chlorine is a hazardous substance. The chemical element chlorine is a
greenish-yellow, toxic gas with a pungent odour, which can be detected
in the air at concentrations below 1 ppm (= 1 ml/m³).
Chlorine is 2.5 times heavier than air and accumulates at ground level.
Chlorine is extremely toxic for water organisms. The reason for the
toxicity of chlorine is its extraordinary reactivity. It reacts with animal and
vegetable tissue and thus destroys it.
Air with a chlorine gas content of 0.5 -1% leads to a quick death in
mammals and humans, as it attacks the respiratory tract and the
pulmonary alveolus (formation of hydrogen chloride or hydrochloride
acid).
Note
Faults due to insufficient chlorine quality
Impurities in the chlorine gas form deposits in devices and valves and
can attack the components chemically. This can lead to malfunctions.
ðOnly use technically pure chlorine that meets the following
requirements:
- Mass content of chlorine at least 99.5%
- Water content max. 20 mg/kg
Chlorine that complies with EN 937 meets these requirements

Cl2
H2O
M
Structure of a vacuum dosing system
The chlorine gas leaves the chlorine tank with positive pressure. The
vacuum regulator aonly permits the chlorine to flow if a vacuum at the
output of the device generates suction. A chlorine leak is not possible
following a line fracture behind the vacuum regulator.
The dosing device consists of a flow meter bwith a manual regulation
valve, usually an electrically-actuated regulation valve cand a pressure
regulator d.
The injector fgenerates the vacuum in accordance with the Venturi
effect and mixes the chlorine gas in the motive water flow. Chlorine
dosing is aborted immediately following water stand still.The non-return
valve eprevents water from entering the dosing devices.

4.2.3 Functions of the device
Fig. 4:
M
Functional diagram C 2526
As the dosing device is connected to a vacuum regulator, chlorine can
only flow if the injector (8) generates a sufficient vacuum.
The float in the flow meter (3) shows the current dosing quantity. It is set
on the manual valve (2).
The majority of dosing devices are fitted with an electrically-actuated
regulation valve (1) with which the dosing quantity can be adjusted
automatically. In a number of cases, an additional signal converter (4) is
provided, with which the dosing device can be adjusted minimally to the
usage process.
The backpressure regulator (6) ensures a constant vacuum on the regula-
tion valve and enables consistent dosing. Should the vacuum generated
by the injector become stronger, the diaphragm disc moves upwards and
reduces the flow cross-section. This produces a constant vacuum
between the regulation valve and the backpressure regulator. The
vacuum meter (5) shows the uncontrolled vacuum of the injector.A
contact vacuum meter is optionally available, with which the injector
function can be electrically monitored.
The chlorine is mixed with water in the injector (8) and flows into the
metering point as a chlorine solution. Should the system come to a
standstill, the non-return valve (7) protects the dosing device from water
penetration.
