How does it work?
SYSTEM DESCRIPTION
PURIFICATION TAKES PLACE IN TWO STAGES.
1. During the pre-ltration stage an active carbon lter removes unwanted odors or tastes
(and within specied limits chlorine and volatile organic compounds) and a 5-micron
preliminary lter that lters out grains and other large particles.
2. After having passed through the pre-ltration unit, the water is pushed into the
purication unit to an electric pump, which pumps the water under high-pressure (6 bar)
through the membrane lter.
In the membrane lter, two separate water streams are generated.
1. A puried water stream, which is, led to the conductivity and ow meters, and then leaves
the purication unit.
2. A reject water stream that leaves the purication unit through the reject water outlet.
The puried water stream is led to the mineral cartridge and from there to the water faucet; the
rejected water is led into the domestic drain system.
MEMBRANE PURIFICATION AND REGENERATING PRINCIPLE
The following happens during the purication process:
1. After pre-ltration the pressure of the water is increased to 6 bar before being pressed
through the membrane.
2. As the feed water is pushed through the membrane lter, the suspended dissolved
pollutants collide with the membrane tissue and stick to it. Eectively removing all harmful
contaminants in the water.
* The reject and our automated back-ush enables the system to take care
and clean itself. This enables a longer membrane lifetime while ensuring
only the highest quality of pure water to leave the system.
3. During the process the pressure of the water is reduced to 2 bars which is also the
pressure at which the pure water leaves the system.
4. Optionally, before reaching the tap the water can be mineralized using our mineral
cartridge.
CONTROLLING THE PROCESS
When the system is powered up, and a correct feed water pressure (between 2 bar and 6 bar) is
detected, the solenoid valve in the feed water inlet tube is opened, and water from the ltration
unit tted between the feed water source and the purication unit is admitted to the purication
unit. At this entry point also a temperature sensor and a non-return valve are tted.

Innovative purication solutions
www.aquablu.com
9
From the entry point the feed water is pushed under feed water pressure to an electrical pump
that forces the feed water under high pressure through the membrane. Pump pressure is
monitored in the pressure line to the membrane, while pump motor current is also measured as a
process parameter.
Once the puried water is through the membrane its temperature, electro-conductivity and
ow rate are measured to monitor the quality and quantity which determines the membranes
condition.
A pressure regulator provides the correct back-pressure in the reject stream to reach the nominal
pressure on the membrane. During a ush an additional solenoid valve opens a by-pass channel
which makes it possible to use the full pump pressure. All ushes are automatic but can also be
initiated manually.
All sensors and valves are contained in the measuring and control block that also houses a CPU
that translates pressure and temperature into digital information. From the purication unit the
water is led through the mineral cartridge (optionally) and from the mineral cartridge to the water
faucet. See gure 8 for an explanation of the valve block.

System overview
Fig. 10: System overview
1) The raw water enters the pre-ltration kit in order to remove large contaminants (5 micron).
2) The water enters the system and is pressurized over our unique spiral wound membrane.
Customisable to every raw water quality, our membranes remove contaminants up to 0.0001
microns in size. This includes viruses, antibiotics and micro-plastics.
3) By monitoring ow, quality, pressure and temperature of your water, our systems give you
insight into the quality of your drinking water. NFC allows information readout though our
Aquablu app and ensures worldwide service and system control.
4) Rejected water ows out of the system.
5) Before the water reaches the tap, there is an option to add extra minerals using our mineral
cartridge to ensure great taste (Alkaline 8).
In water mains fed systems, the reject water may under no circumstances be fed back into the system! Not
observing this may cause a serious health hazard to the water mains system! Discard the reject water in the
sewage system or (preferably) in a grey water system.

How does it communicate?
Simple communication between any machine and its user is the basic rule to gain trust in technical
equipment. Understanding that not all Aquablu owners are chemical engineers nor masters of uid
technologies, simple communication is one of the corner stones of our development.
Smart communication via NFC enables you to get direct insights into the technical status of your
system and the water quality at any moment of time. The read out is performed using the Aquablu
app. The more scans you perform the better it allows you to share the responsibility for the
maintenance directly with your local Aquablu service partner without any additional costs or eort.
On top of that, the Aquablu One is also tted with a multi color light and a LED indication on tap
level which indicate the system status in a more conventional way.
NFC NEAR FIELD COMMUNICATION
The CPU of the purier controls over 96 parameters and thereby monitors the water quality as well
as the technical status of the system. This data can be read out by holding the Aquablu app close to
the NFC sign on the left side of the Aquablu One casing. The NFC will launch the service web page
and will provide you with a list of all vital information. Subsequently, the whole list of 96 parameters
is sent to your local Aquablu service partner, as well as to the Aquablu HQ. This information allows
technical insight into the system and determines if any physical maintenance is required.
In order to activate the NFC in your smartphone, you must download the Aquablu app in the IOS or
Google play store.

How does it communicate?
DESCRIPTION OF CONTROLS AND VISIBLE AND AUDIBLE SIGNALS
See gure 11c below for the location of the controls
Fig. 11: Overview of controls
Once the Aquablu One is connected to the power adapter it is always “on”. Therefore the only
way to completely turn o the system is by disconnecting the 24 V DC power adapter.
If the system is running as intended it can remain “on” indenitely. However, some errors and part
replacements may require a full restart which is initiated by interrupting the electrical supply and
reconnecting the machine to the power adapter.
If the purication system requires attention, the blue light on the water faucet starts to ash red.
A ashing blue light at the faucet indicates that the system is performing a ush, ashing blue
during production indicates a warning of low quantity or quality of the permeate water.
The purication unit itself communicates its status by means of the status light on the front of the
unit, and by audible signals. This can be used in case you do not have a phone near you. However,
we always recommend to use NFC to make connection between the Aquablu app and the system
to communicate with your Aquablu product.
To provide detailed communication, both the status light and the audible signalling have a range
of dierent signals available. Light signals are used for normal communication, and audible signals
are only used in “emergency” situations, where immediate action of the operator is required.

Innovative purication solutions

Installing your Aquablu One
The installation of the system can be divided in four
stages:
1) Mechanical installation
2) Hydraulic installation
3) Electrical connection
4) Commissioning
1. Mechanical installation
The mechanical installation consist of installing the
ltration unit, the mineral cartridge and the LED water
faucet. Make sure to install all components, hoses and
cables in such a manner that they are not in contact or
exposed to a heat source.
1.1 PREFILTRATION UNIT
The ltration housing has mounting holes on top to which the blue mounting plate supplied in the
set must be attached. Make sure to install it that way that both vent plugs can be reached.
For this purpose three screws of the correct diameter and length are supplied. It is imperative
only these screws, or screws with identical dimensions (15 × 3), are used to prevent damage to the
lter housing.
The mounting plate can be attached to the lter housing from both sides according to the
available space underneath your sink. The direction of ow is indicated on the housing.
See gures 12a and 12b below for a visual reference.
Fig. 12a: Right hand bracket mounting Fig 12b: Left hand bracket mounting
With the mounting plate tted to the top of the ltration unit, the unit must be attached to the
appropriate side of the cabinet. Keep in mind that the vent plugs must be accessible.
The unit must be located in such a way that the clear plastic lter containers can be removed
later for installing and/or changing the lter elements. The unit must be located in such a way that
the connecting hoses can be tted without sharp bends or kinks.
Please install the unit as close to horizontal as possible.
It is advised to t both lter cartridges to the unit at this stage. The black cartridge (activated
carbon) must be closest to water source, the white cartridge between the black cartridge and the
purication unit. Flush out excessive carbon dust from the activated carbon cartridge under your
standard faucet before inserting the cartridge in the ltration unit.

Innovative purication solutions
www.aquablu.com
17
1.2 MINERAL CARTRIDGE
The mineralization unit is held by two clamps that are attached to the appropriate side of the
cabinet, just underneath the faucet. To avoid unwanted air bubbles, it has to be installed vertical.
The unit must be located in such a way that the connecting hoses can be tted without sharp
bends or kinks.
1.3 WATER FAUCET
1. First determine the correct mounting location of the water faucet on the sink. The tting
instructions are only applicable to the water faucet supplied with the kit. Other faucets must be
installed according to the instructions supplied with that faucet.
2. After correctly determining the location a 20 mm diameter hole must be made. It is advised
to use a 20 mm hole saw to cut the required hole. See Fig.13a for an illustration of a hole saw.
Smoothen the edges of the hole and remove all debris and sawdust in the cabinet.
3. The sealing plate, the mounting socket and the collapsible anchor must be assembled as shown
in the gure 13b below.
Fig 13a: Hole saw example Fig. 13b: Pre assembly of mounting socket
4. Push the assembly through the hole in the sink, unfold the collapsible anchor and rotate the
anchor into a position that oers a at and rigid surface.
5. Rotate the mounting socket with the cam lock coupling in such a position that the water faucet
is in the correct position when locked into the mounting socket. Use the hole with the locking
screw as reference.
6. With the anchor in position, the central Phillips head screw must be tightened until the
mounting socket is rmly fastened to the sink.
NOTE:
It is advised to insert the water hose that connects the water faucet with the mineral cartridge
into the push-in coupling of the water faucet before you x it to your sink. Once installed, the
tting can be dicult to reach. See chapter “Hydraulic installation” for further instructions.

Innovative purication solutions

7. Insert the water faucet hose and electrical cable through the hole in the mounting socket.
Make sure the hose and the cable run smoothly through the socket and the hole.
8. Place the water faucet body onto the mounting socket, in such a way that the locking cams on
the lower faucet body line up with the apertures in the mounting console, as shown in gure 14a.
9. Push the faucet body onto the mounting console and rotate counter clock to lock the faucet
body in the console, as shown in gure 14b. Do not force the connection, if unreasonable forced is
required, check if anything is wrong and retry.
Fig.14a: Placing faucet on mounting socket Fig.14b: Faucet in locked position
10. With the faucet body correctly tted to the mounting console, the body must be secured to
the console by means of a locking screw. See the gure below for the nal situation, and the
location of the locking screw.
Fig.15: Correctly mounted water faucet
11. Turn the screw in with the Allan key provided until tight. Please do not over tighten the screw
to prevent any accidental damage.
12. The mechanical installation of the water faucet is ready.

2. Hydraulic installation
HOSE PREPARATION
It is essential the hoses are cut o as straight as possible to prevent leakage. After cutting, any
rough edges need to be removed and the cut needs to be cleaned. Bevelling the hose ends slightly
will aid the assembly. Use a sharp knife or scissor to prevent crimping of the hose. Make sure to
install all hoses in such a manner that they are not in contact or exposed to a heat source.
HOSE LENGTHS
With the components tted and placed in their respective nal locations, the hose lengths can
be determined. The hoses must be dimensioned in such a way that they can be tted to the
individual components without sharp bends, kinks or over-stretching. Allow for over length to
move the unit when the membrane needs to be replaced. In case the hose sections supplied in the
kit are not sucient to complete the installation as is explained in this manual, extra hose might
be required. Make sure that, when purchasing extra hose from external sources the hoses are of
the correct diameter and are genuine food quality.
Two types of connections are used in the installation.
1. Push-in connections
With push-in connectors, the correctly prepared hose is simply pushed into the coupling.
Pushed in suciently, the hose will bottom on a ridge inside the coupling (Fig. 16a).
After the hose bottoms, the hose must be pulled backwards (away from the connector) to
lock the coupling. Pulling back the hose also pulls back the locking ring on the coupling,
and with the hose rmly pulled back a leak free connection has been made (Fig. 16b).
The hose can be removed from the coupling by means of pushing the locking ring in and at
the same time pulling the hose out (Fig. 16c).
It is advised to closely inspect the hose for damage after removal before using it again.
In case of doubt the damaged or suspect section must be cut o. See gures below for
push-in coupling handling.
Fig. 16a: Inserting the hose Fig. 16b: Locking the hose Fig. 16c: Removing the hose
2. Screw on connections
With the kit two of screw/push-in connectors are supplied to connect the system to the
water supply, and to the drain system. See gure 17 below for their appearance and
application.
Fig. 17: Screw on connection
