2 Safety
2.1 Safety measures
●Only operate your product if all components are installed properly.
●Obey the local regulations on drinking water protection, accident prevention and
occupational safety.
●Do not make any changes, alterations, extensions or program changes on your
product.
●Only use genuine spare parts for maintenance or repair.
●Keep the premises locked against unauthorised access to protect imperilled or
untrained persons from residual risks.
●Comply with the maintenance intervals (refer to chapter 8.2). Failure to comply can
result in the microbiological contamination of your drinking water system.
●Be aware of a possible slip hazard due to leaking water on the floor.
2.1.1 Mechanical hazards
●You must never remove, bridge, or otherwise tamper with safety equipment.
●For all work on the system that cannot be carried out from the ground, use stable,
safe and self-standing access aids (e.g. stepladders).
●Make sure that the system is set up in a way that it cannot tip over and that the
stability of the system is guaranteed at all times.
2.1.2 Pressure-related hazards
●Components can be under pressure. There is a risk of injuries and damage to
property due to escaping water and unexpected movement of components. Check
the system’s pressure lines for leaks at regular intervals.
●Before starting any repair and maintenance work, make sure that all affected
components are depressurised.
2.1.3 Electrical hazards
There is an immediate danger of fatal injury from electric shock when touching live parts.
Damage to the insulation or individual components can be life-threatening.
●Only have qualified electricians carry out electrical work on the system.
●In case of damage to live components, switch off the voltage supply immediately
and arrange for repair.
●Switch off the supply voltage before working on electrical system parts. Discharge
residual voltage.

Safety
11 | 64
BA-100174850000_en_034_GENODOS_DME 6-100_GENODOS DME Delta-p.docx
●Never bridge electrical fuses. Do not disable fuses. Use the correct current ratings
when replacing fuses.
●Keep moisture away from live parts. Moisture can cause short-circuits.
2.1.4 Danger due to chemicals
●Chemicals can be hazardous to health and environment.
They can cause chemical burns to skin and eyes as well as irritation of the
respiratory tract or allergic reactions.
●Avoid any skin/eye contact with chemicals.
●Use personal protective equipment.
●Read the safety data sheet before handling chemicals. Obey the instructions for
different activities/situations.
●Current safety data sheets for chemicals are available for download at
www.gruenbeck.de/en/info-centre/safety-data-sheets.
●Obey in-house instructions when handling chemicals. Make sure that protective
and emergency equipment such as emergency showers and eyewash are
available where required, and functional.
Mixing and residual amounts of chemicals
●Do not mix different chemicals. Unforeseeable chemical reactions posing a lethal
danger can occur.
●Dispose of residual amounts of chemicals in accordance with local regulations
and/or in-house instructions.
●Residual amounts from used canisters should not be transferred into canisters with
fresh chemicals in order not to impair the effectiveness of the chemicals.
Labelling/Minimum shelf life/Storage of chemicals
●Check the labelling of the chemicals. Chemical labels must not be removed or
made illegible.
●Do not use any unknown chemicals.
●Comply with the use-by date (minimum shelf life) stated on the label.
●If stored incorrectly, chemicals could change their state of matter, crystallize,
outgas, or lose their effectiveness. Store and use the chemicals at the indicated
temperatures only.
Cleaning/Disposal
●Immediately absorb leaked chemicals with suitable binding agents.
●Collect and dispose of chemicals in such a way that they cannot pose any risks to
people, animals, or the environment.

3.3 Functional description
GENODOS DME 6 –100
By means of a contact water meter with pulse generator, the dosing system
GENODOS DME registers the water volume flowing through and sends the control pulses to
the electronics of the dosing pump GENODOS GP according to the pulse interval of the
contact water meter.
GENODOS DME Delta-p
The dosing system DME Delta-p is tuned to the IONO-matic3control unit (starting from
software version V3.05 and higher) of the Delta-p.
The electronics of the dosing pump GENODOS GP-2/40 receives the dosing signal from the
control unit of the Delta-p water softener via the pulse connection cable.
The exaliQ mineral solution is injected into the drinking water pipe via the (optional) insert
with injection point for the dosing valve which is mounted on the soft water outlet of the
Delta-p water softener.
General
The electronics controls the dosing pump and thereby determines the dosing volume of the
mineral solution into the water pipe.
The mineral solution is withdrawn from the respective canister containing the mineral
solution by means of a suction lance and added to the water.
An electronic level control switches the pump off when the canister containing the mineral
solution is empty.
A yellow LED on the electronics of dosing pump GENODOS GP visually signals the need for
a replacement of the canister.

3.5 Mineral solutions
Grünbeck Wasseraufbereitung GmbH confirms that the mineral substances contained in the
colourless liquid concentrates correspond to the publication of the list of treatment
substances and disinfection procedures in accordance with §11 of the German Drinking
Water Ordinance –19th amendment (status: December 2017).
Mineral solution
Effect
Material
exaliQ control
Rehabilitation
Galvanised pipes
For the rehabilitation of corroded zinc pipes (often recognisable by brown-coloured water).
After the rehabilitation (approx. 6 months): Change to a different exaliQ dosing agent.
exaliQ safe
Corrosion protection
Galvanised pipes and
copper materials/brass
For corrosion protection of water in the hardness range soft to medium (up to 14 °dH) as well as downstream of
water softeners. For water temperatures up to 60 °C. To reduce the introduction of heavy metals (e.g. lead).
exaliQ safe+
Corrosion protection and
hardness stabilisation
Galvanised pipes and
copper materials/brass
For hardness stabilisation and corrosion protection of water in the hardness range up to 21 °dH and to reduce
the introduction of heavy metals (e.g. lead). For water temperatures up to 60 °C. For water temperatures up to
60 °C. In case of a water hardness > 21 °dH, we recommend a water softener (e.g. softliQ:SD21) to treat the
hardness and then to change to exaliQ safe.
exaliQ pure
Hardness stabilisation
Galvanised pipes and
copper materials/brass
For circulation water in solar systems or installation of the dosing technology in the cold water inlet to the
decentralised water heater. For high temperatures up to 80 °C and/or hard water with a total hardness > 21 °dH
(total alkalinity > 15 °dH ).
Note: Copper and brass materials are only suitable for warm water. Consultation with Grünbeck
Wasseraufbereitung GmbH recommended prior to first application.
exaliQ neutra
Increase of pH value
Galvanised pipes and
copper materials/brass
Corrosion protection for soft water with high carbon dioxide concentrations as well as downstream of water
softeners.
Corrosion protection due to the binding of free carbon dioxide and an increase of the pH value.
Note: The mineral solution exaliQ neutra must not be used with dosing system GENODOS DME Delta-p. The
stand-alone dosing system GENODOS DME 6 –100 must be used.

Product description
20 | 64
BA-100174850000_en_034_GENODOS_DME 6-100_GENODOS DME Delta-p.docx
The shelf life of the mineral solutions is 2 years following the filling date (protected against
cold and light).
●Once the canister has been opened, it is recommended to use up the contents
within 6 months, but within 12 months at the latest.
When changing from the mineral solution to another dosing agent, the dosing system must
be flushed (refer to chapter 8.6).
The mineral solutions are hygienically packaged at the factory and sterilely sealed with a
secured screw cap.
The ready-to-use concentrates are designed for a pump capacity of 100 ml/m³ drinking water
flow.
