1. Safety instructions
These installation and operating instructions contain
general instructions that must be observed during
installation, operation and maintenance of the pump.
It must therefore be read by the installation engineer
and the relevant qualified operator prior to
installation and start-up, and must be available at the
installation location at all times.
1.1 Identification of safety instructions in
these instructions
The safety instructions are identified by the following
symbols:
1.2 Qualification and training of personnel
The personnel responsible for the installation,
operation and service must be appropriately
qualified for these tasks. Areas of responsibility,
levels of authority and the supervision of the
personnel must be precisely defined by the operator.
If necessary, the personnel must be trained
appropriately.
Risks of not observing the safety instructions
Non-observance of the safety instructions may have
dangerous consequences for the personnel, the
environment and the pump and may result in the loss
of any claims for damages.
It may lead to the following hazards:
• Personal injury from exposure to electrical,
mechanical and chemical influences.
• Damage to the environment and personal injury
from leakage of harmful substances.
1.3 Safety instructions for the
operator/user
The safety instructions described in these
instructions, existing national regulations on health
protection, environmental protection and for accident
prevention and any internal working, operating and
safety regulations of the operator must be observed.
Information attached to the pump must be observed.
Leakages of dangerous substances must be
disposed of in a way that is not harmful to the
personnel or the environment.
Damage caused by electrical energy must be
prevented, see the regulations of the local electricity
supply company.
Only orginal accessories and original spare parts
should be used. Using other parts can result in
exemption from liability for any resulting
consequences.
1.4 Safety of the system in the event of a
failure in the dosing pump
The dosing pump was designed according to the
latest technologies and is carefully manufactured
and tested.
If it fails regardless of this, the safety of the overall
system must be ensured. Use the relevant
monitoring and control functions for this.
Warning
If these safety instructions are not
observed, it may result in personal
injury!
Caution
If these safety instructions are not
observed, it may result in malfunction
or damage to the equipment!
Note
Notes or instructions that make the job
easier and ensure safe operation.
Caution
Before any work to the pump, the pump
must be in the ’Stop’ operational state
or be disconnected from the mains.
The system must be pressureless!
Caution
Make sure that any chemicals that are
released from the pump or any
damaged lines do not cause damage to
system parts and buildings.
The installation of leak monitoring
solutions and drip trays is
recommended.

1.5 Dosing chemicals 2. General
The DDA dosing pump is a self-priming
diaphragm pump. It consists of a housing
with stepper motor and electronics, a
dosing head with diaphragm and valves and the
control cube.
Excellent dosing features of the pump:
• Optimal intake even with degassing media, as
the pump always works at full suction stroke
volume.
• Continuous dosing, as the medium is sucked up
with a short suction stroke, regardless of the
current dosing flow, and dosed with the longest
possible dosing stroke.
2.1 Applications
The pump is suitable for liquid, non-abrasive, non-
flammable and non-combustible media strictly in
accordance with the instructions in these installation
and operating instructions.
Areas of application
• Drinking water treatment
• Wastewater treatment
• Swimming pool water treatment
• Boiler water treatment
• CIP (Clean-In-Place)
• Cooling water treatment
• Process water treatment
• Wash plants
• Chemical industry
• Ultrafiltration processes and reverse osmosis
•Irrigation
• Paper and pulp industry
• Food and beverage industries
2.2 Improper operating methods
The operational safety of the pump is only
guaranteed if it is used in accordance with section
2.1 Applications.
Warning
Before switching the supply voltage
back on, the dosing lines must be
connected in such a way that any
chemicals in the dosing head cannot
spray out and put people at risk.
The dosing medium is pressurised and
can be harmful to health and the
environment.
Warning
When working with chemicals, the
accident prevention regulations
applicable at the installation site
should be applied (e. g. wearing
protective clothing).
Observe the chemical manufacturer's
safety data sheets and safety
instructions when handling chemicals!
Warning
If the diaphragm leaks or is broken,
dosing liquid will escape from the
discharge opening on the dosing head
(see fig. 3).
Take suitable precautions to prevent
harm to health and damage to property
from escaping dosing liquid!
Check daily whether liquid is escaping
from the discharge opening!
Changing the diaphragm, see section
7. Service.
Caution
A deaeration hose, which is routed into
a container, e. g. a drip tray, must be
connected to the deaeration valve.
Caution
The dosing medium must be in liquid
aggregate state!
Observe the freezing and boiling points
of the dosing medium!
Caution
The resistance of the parts that come
into contact with the dosing medium,
such as the dosing head, valve ball,
gaskets and lines, depends on the
medium, media temperature and
operating pressure.
Ensure that parts in contact with the
dosing media are resistant to the
dosing medium under operating
conditions, see data booklet!
Should you have any questions
regarding the material resistance and
suitability of the pump for specific
dosing media, please contact
Grundfos.
Warning
Other applications or the operation of
pumps in ambient and operating
conditions, which are not approved,
are considered improper and are not
permitted. Grundfos cannot be held
liable for any damage resulting from
incorrect use.
Warning
The pump is NOT approved for
operation in potentially explosive
areas!
Warning
A sunscreen is required for outdoor
installation!

deviates or if dosing a medium whose viscosity
deviates, the pump must be calibrated.
For pumps with FCM control variant, it is not
necessary to calibrate the pump if there is deviating
or fluctuating backpressure as long as the
’AutoFlowAdapt’ function has been enabled
(see section 6.10 AutoFlowAdapt).
Requirements
• The hydraulics and electrics of the pump are
connected (see section 4. Assembly and
installation).
• The pump is integrated into the dosing process
under operating conditions.
• The dosing head and suction hose are filled with
dosing medium.
• The pump has been deaerated.
Warning
The deaeration hose must be
connected correctly and inserted into a
suitable tank!
Note
Press the 100 % key and
simultaneously turn the clickwheel
clockwise to increase the duration of
the process to up to 300 seconds. After
setting the seconds, do not press the
key any longer.

Calibration process - example for DDA 7.5 - 16
1. Fill a measuring beaker with dosing medium.
Recommended filling volumes:
2. Read off and note down the fill volume V1
(e.g.300ml).
3. Place the suction hose in the measuring beaker.
4. Start the calibration process in the ’Setup >
Calibration’ menu.
5. The pump executes 200 dosing strokes and
displays the factory calibration value
(e.g.125ml).
6. Remove the suction hose from the measuring
beaker and check the remaining volume V2
(e.g.170ml).
7. From V1and V2 , calculate the actual dosed
volume Vd = V1-V2
(e. g. 300 ml - 170 ml = 130 ml).
8. Set and apply Vdin the calibration menu.
– The pump is calibrated.
