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
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/her and possible dangers that

3.3 General Safety Information
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.
WARNING!

3.4 Intended Use
Intended Use
The unit is designed to measure and regulate the
pH value and chlorine content in swimming pools.
Usually the integrated metering pumps are
intended for metering the necessary chemicals.
Only connect other feeder assemblies, such as
electrolysis systems or calcium hypochlorite sys‐
tems, if these systems are intended for use in
swimming pools.
Only use the unit in accordance with the technical
details and specifications provided in these oper‐
ating instructions and in the operating instructions
for the individual components (such as sensors, fit‐
tings, calibration instruments, metering pumps
etc.).
All other uses or modifications are prohibited.

DULCODOS® Pool metering systems must be
free from feed chemicals and water
– Rinse out the media carrying parts, including
the tubes using clean, pure water
– Transport and store the DULCODOS® Pool
metering systems in their original packaging
– Also protect the packaged DULCODOS® Pool
metering systems against damp, exposure to
chemicals and mechanical effects
– Please also observe the operating instructions
for controllers and fittings and other units, such
as sensors, filters, metering pumps ...

5.1 Wall mounting
Secure the metering system perpendicular and
upright on a wall or a stable mounting system.
The metering system should be freely accessible.
Select the mounting height you require so that:
nThe controller's display can be easily read
nThere is still space for maintenance work beneath the in-line
probe housing (100 mm)
nThere is still room for the chemical storage tank (600 mm)
nThe fluid level of the full chemical storage tanks is below the
metering pumps
nThe maximum priming lift of the metering pumps is not
exceeded.

5.2.1 Metering system
NOTICE!
Maximum permissible operating pressure of in-line
probe housing
Limit the pressure to a maximum of 2 bar (at 30
°C) directly at the sample water extraction point
using a pressure reducer, otherwise the maximum
permissible operating pressure of the in-line probe
housing will be exceeded.
Do not allow a back pressure of more than 2 bar
(at 30 °C) to build up at the outlet, otherwise the
maximum permissible operating pressure of the in-
line probe housing will be exceeded.
1. With flow sensor: Push the flow sensor into the in-line probe
housing and tighten the reducing nipple and the mounting
clip
2. Route the sample water feed via a ball valve from the filter
circuit to the in-line probe housing, see figures above
3. Route the sample water feed via a ball valve from the filtra‐
tion circuit to the in-line probe housing, see figures above
4. Install a 1/2" straight union on the filtration circuit pipe for
each injection valve
5. Screw the injection valves into a straight union of the filtration
circuit pipe

To ensure reliable measuring and control, the
sample water must be free from air bubbles.
1. Set a flow of 20 ... 60 l/h using the stopcock (read-off at the
top edge of the float).
2. Check the hydraulic leak-tightness of the system (escaping
liquid, continuous air bubbles in the in-line probe housing, ...)
ðTighten the threaded connectors if necessary.
1.
Have a collecting vessel at the ready
Open the sampling tap
2. If water flows out of the sampling tap, the system is not under
negative pressure and is working correctly
If air is drawn in, this means that there is
negative pressure in the system. In this case,
throttle the valve at the point at which the
sample water pipe enters the filtration circuit -
the pressure should not exceed 2 bar.
3. Use the stopcock on the sample water drain to finely adjust
the system
5.2.2 Sensors
Observe the operating instructions for the sensors.
1. Close the shut-off valves upstream and downstream of the
in-line probe housing
2. Remove the transparent protective cap from the ball-shaped
end of the pH sensor
3. Manually screw both the pH sensor and the redox sensor into
separate threaded holes on the in-line probe housing. Then
carefully tighten using an SW 17 open-ended spanner until
the threaded connector is tight
4. Testing the sensors' hydraulic installation: Adjust the flow
using the shut-off valve to 20... 60 l/h
ðCheck whether the threaded connectors on the in-line
probe housing are tight.
Testing the hydraulic installation of
the metering system:
Check the system for negative pres‐
sure
