1 Introduction
These operating instructions describe a mobile metering station for
potable water disinfection for short-term, temporary use. The disin‐
fectant can be metered in situ using the fully ready mounted and
ready connected station. All disinfectants permitted in accordance
with the Drinking Water Ordinance 2001 and the List of Permitted
Substances (§11) can be used.
The mobile metering station can be used to eliminate contamina‐
tion by micro-organisms, as well as for prescribed flushing and dis‐
infection when commissioning newly laid pipes or recently installed
systems, after repairs or after longer periods of idleness.
nFor the disinfection of potable water in accordance with the
Drinking Water Ordinance 2001 and the List of Permitted Sub‐
stances (§11).
nAs an immediate measure in the event of acute contamination.
nFor operators of widely ramified water supply systems and
lines, such as municipalities, hospitals, elderly care homes,
sports and leisure facilities and barracks, and in industry and
commerce for “shock” disinfection should there be a legionella
incident.
nFor aid organisations to set up mobile potable water disinfec‐
tion stations in crisis regions.
nFor plumbing businesses for disinfection purposes when com‐
missioning water supply systems.
nFor the flushing and disinfection of potable water and process
water lines at events, such as concerts, village fairs etc.
The emergency chlorination station 1081318 consists of the fol‐
lowing components:
nSupport frame with collecting pan for a 35 kg canister (canister
is not included in the scope of delivery of the metering station).
nBracket for the metering pump (PE-HD natural).
nWinding bracket for the metering hose.

– Denotes hints on use and other useful informa‐
tion. It does not indicate a hazardous or dam‐
aging situation.
2.2 General safety information
Ensure that there can be no unauthorised access to the unit.
Make sure that only trained personnel fit, install, maintain and
operate the unit.
Please also observe the operating instructions for the metering
pump and any other units which may be fitted!
Only use the sensor in bypass fittings, which ensure the correct
flow parameters (l/h, see Technical data).
Pay attention to the resistance of the wetted materials of all units,
referring to the ProMinent Resistance List in the product catalogue
or at www.prominent.com .
Check the resistance of any pre-mixed chemicals with the chemical
manufacturer before using.
WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐
ries.
Please ensure when handling hazardous sub‐
stances that you have read the latest safety data
sheets provided by the manufacture of the haz‐
ardous substance. The actions required are
described in the safety data sheet. Check the
safety data sheet regularly and replace, if neces‐
sary, as the hazard potential of a substance can be
re-evaluated at any time based on new findings.
The system operator is responsible for ensuring
that these safety data sheets are available and that
they are kept up to date, as well as for producing
an associated hazard assessment for the worksta‐
tions affected.
2.3 Intended use
The metering system is only designed for metering liquid feed

The metering system is not intended for metering slightly flam‐
mable or explosive media.
The metering system is not suitable for use in premises at risk of
explosion.
Do not operate the system under conditions other than those
described in the technical data.
2.4 User qualification
WARNING!
Danger of injury with inadequately qualified per‐
sonnel
The operator of the system / equipment is respon‐
sible for ensuring that the qualifications are ful‐
filled.
If inadequately qualified personnel work on the unit
or loiter in the hazard zone of the unit, this could
result in dangers that could cause serious injuries
and material damage.
– All work on the unit should therefore only be
conducted by qualified personnel.
– Unqualified personnel should be kept away
from the hazard zone.
The pertinent accident prevention regulations, as
well as all other generally acknowledged safety
regulations, must be adhered to.
Training Definition
Instructed personnel An instructed person is deemed to be a person who has been instructed and,
if required, trained in the tasks assigned to him and possible dangers that
could result from improper behaviour, as well as having been instructed in the
required protective equipment and protective measures.
Trained user A trained user is a person who fulfils the requirements made of an instructed
person and who has also received additional training specific to the system
from the manufacturer or another authorised distribution partner.
Trained, qualified per‐
sonnel
A trained, qualified employee is deemed to be a person who is able to assess
the tasks assigned to him and recognize possible hazards based on his
training, knowledge and experience, as well as knowledge of pertinent regula‐
tions. A trained, qualified employee must be able to perform the tasks
assigned to him independently with the assistance of drawing documentation
and parts lists. The assessment of a person's technical training can also be

ognise and avoid possible dangers independently based on his technical
training and experience as well as knowledge of pertinent standards and regu‐
lations. An electrical technician must be able to perform the tasks assigned to

The metering pumps can only be flushed from the suction side to
the discharge site.
1. Connect the suction lance to the flushing medium. Make sure
that you use a flushing medium that does not cause serious
chemical reactions with any residual feed chemical. To this
end, refer to the material safety data sheet for the feed chem‐
ical and the material safety data sheet for the flushing
medium.
2. Collect the contaminated flushing medium in a storage tank
and dispose of it in accordance with local regulations. To this
end, refer to the material safety data sheet for the feed chem‐
ical and the material safety data sheet for the flushing
medium.
Please use the operating instructions for the metering pump and
back pressure valves to rectify any functional faults.
