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 groups of 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.
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 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 lethal.
●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 voltage supply before working on electrical components.

Safety
10 | 104
BA_100221820000_en_044_osmoliQ-LB
Before starting work on active system parts, make sure they are de-energised. Make sure
they stay de-energised for the duration of the work. Obey the 5 safety rules below:
a Disconnect (unplug the power plug)
b Secure against restart
c Verify that no voltage is present
d Ground and short-circuit
e Cover or block off adjacent live parts
●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 skin and eye burns 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 and always obey the
instructions for the different actions/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 and make sure that any
protective and emergency equipment such as emergency showers and eye
showers is present and functional.
Mixing and residual amounts of chemicals
●Never 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 containers should not be transferred into containers
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 - labels must not be removed or rendered
illegible.
●Do not use any unknown chemicals (no labelling or labelling illegible).
●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 specified
temperatures only.

Safety
11 | 104
BA_100221820000_en_044_osmoliQ-LB
Cleaning/Disposal
●Immediately absorb leaked chemicals with suitable binding agents.
●Collect and dispose of chemicals in such a way that they cannot pose a risk to
people, animals, or the environment.
2.1.5 Groups of persons requiring protection
●Children must not play with the product.
●This product must not be used by persons (including children) with limited abilities,
lack of experience or knowledge.
●Cleaning and maintenance must not be carried out by children.

3.4 Functional description
The osmoliQ:LB works according to the reverse osmosis principle.
The feed water is directed to the high-pressure pump via a fine filter and an automatic fitting.
An optical sensor in the pump sends a message to the control unit in the event of a lack of
feed water and protects the pump from running dry. The frequency converter communicates
with the system controller and regulates the pump speed in a way that the permeate capacity
remains constant - irrespective of the inlet pressure or the feed water temperature. With the
controller, the permeate capacity can be reduced by up to 20 %.
From the pump, the feed water is directed to the reverse osmosis membranes and is divided
into the partial flows “permeate” and “concentrate”. A partial flow of the concentrate is
captured by a flow meter and returned to the feed water by means of a control valve
(automatic).
The remaining concentrate is captured by a flow meter and directed to the drain via an
automatic control.
Using the existing feed water pressure, the remaining constituents are flushed from the
osmoliQ:LB via an additional automatic fitting after each operating period (permeate tank
full).

Product description

BA_100221820000_en_044_osmoliQ-LB
3.4.1 Process/function
The pre-treated feed water flows in parallel over the surface of the membrane. The water
recirculated within the system is called FEED.
A partial flow of pure water passes through the membrane as permeate (cross flow), while
the remaining partial flow –with now increased salt concentration –is carried away from the
membrane surface as concentrate. As the concentrate passes through the circuit, it is
concentrated still further.
An RO membrane is characterised by the fact that it has no pores and is "tight". The water
does not flow through the membrane but diffuses through it.
This process can remove minerals dissolved in the water and significantly reduce bacteria,
germs and particles as well as dissolved organic substances.
Over time, minerals and biological contaminants are deposited on the membrane surface.
Therefore, it must be cleaned at regular intervals.

RO process
Reverse osmosis is reversing the natural osmosis process.
A
B
C
Water (diluted solution)
Concentrated solution
Membrane
Osmosis
Explanation
Osmosis occurs when two solutions of different concentrations
of dissolved minerals are separated from each other by a
membrane.
Water passes from the diluted solution (A) through the semi-
permeable membrane (C) to the concentrated solution (B) until
the concentration is balanced on both sides of the membrane.
Osmotic pressure
Explanation
This balance is characterised by the static pressure difference
between the resulting water columns. The pressure difference
is referred to as the osmotic pressure.
The higher the concentration of the dissolved minerals in the
concentrated solution (B), the higher the osmotic pressure
difference (D).
Reversed osmosis
Explanation
In the case of reverse osmosis, the osmotic pressure is
countered by a higher pressure (E).
The process takes place in the reverse direction; water passes
from the concentrated solution (B) through the membrane to
the diluted solution (A).
This way, the water can be demineralised.
