1. FOREWORD
We would offer congratulations on your purchase of the EMERALD for purification and
electrical treatment of fresh water. You have wisely invested in the well-being of your family and
also made a very important step towards improving your health!
The EMERALD is designed to produce the drinkable water with the antioxidant properties at
home from the ordinary tap water, purified from the microbes and microbial toxins, heavy metal
ions and harmful organic compounds. Antioxidant water from the EMERALD has a beneficial effect
on the entire body, normalizes the metabolism and the functioning of internals, cleanses from the
residues and toxins and also strengthens the immune system, improves the memory and increases
the body's energy tone.
The EMERALD was developed jointly with Vitold Bakhir Institute which is the main scientific
center in the field of electrochemical activation of the water. Many years of experience and modern
discoveries by experts from Vitold Bakhir Institute as well as the direct participation of Professor
V.M. Bakhir, Doctor of Technical Sciences and made it possible to combine in the EMERALD the
most advanced technologies of purification and electrical treatment of water.
All the processes of purification and electrical treatment of water in the device are as close as
possible to what happens to water in the animate nature. Reproducing the most complex natural
processes of water purification and treatment has become possible due to the creation of highly
reliable electrochemical modules which are the main elements of the device. The modules consist of
two flow through chambers: anode and cathode ones. Namely the processes of electrical treatment
of water are repeated under the influence of positive and negative current on the anode and cathode
in these chambers which occur in nature.
2. INFORMATION ON ANTIOXIDANT WATER
The human body contains the water more than 70%. The water plays the most important role in
the life activity of the human body. An adult needs to consume about 2-3 liters of water per day to
maintain the normal functioning of the body.
The antioxidant water from the EMERALD has a positive effect on the body when it is used as
a part of the usual ration. The antioxidant water from the EMERALD protects the body from the
action of strong toxic oxidizing agents. The mechanism of action of the antioxidant water is based
on the transfer of protective antioxidant properties to the internal media of the body which
contributes to the protection against the toxic oxidants that are present not only in the water but also
in the air and in the food. The tissue respiration is stimulated which enhances the action of vitamins
and chemical antioxidants in the body. The antioxidant water also reduces the effects of ionizing
radiation, i.e. it exhibits the antiradiation properties specific to the antioxidants. The antioxidant
water improves the passive immunity and the general condition of the body, improves the
functioning of the gastrointestinal tract, urinary tract and normalizes the blood values.
Water purified by the EMERALD retains its antioxidant properties no more than 24 hours from the
moment of treatment. After this period the oxidation-reduction potential (ORP) of the treated water

3
returns to its original ORP of tap water +150 ÷ + 500 mV. When boiling the ORP value of
antioxidant water decreases in absolute value but the water continues to exhibit the properties of the
deoxidizer. The water obtained from the EMERALD should be stored for no more than 24 hours in
the glass containers with the cap closed away from the direct sunlight and the heat sources. Water
treated by the EMERALD meets the requirements of hygienic standards (see Appendix 1
"Certificates").
Cooking – the food on antioxidant water is cooked faster and retains more useful properties. The
antioxidant water is great for the water steeping of fruits, vegetables, fish and meat since due to its
properties this water more actively removes the harmful chemicals from the products such as the
growth hormones and the antibiotics.
Preparation of beverage – together with drinking the antioxidant water purified by the EMERALD
the antioxidant effect can be enhanced due to the phenomena of synergism and the antioxidant
beverage can be prepared using the natural antioxidants using the freshly squeezed carrot, apples
juices and various berries by adding the antioxidant water treated by the EMERALD. The herbal
teas made with this water acquire the special taste and aroma. The ice cubes of frozen antioxidant
water will give the drink an added advantage.
Air humidification – the antioxidant water is useful to apply in the form of fog when it is used in
the humidifiers. The humidified air, with micro droplets of the antioxidant water with the properties
of deoxidizer has the beneficial effect on the respiratory and cardiovascular devices and prevents the
asthma attacks and allergic diseases.
Cosmetic purposes - for cosmetic purposes the antioxidant water is adventitious to use for washing
in the form of ice cubes to wipe the face or spray the water in the form of aerosol to moisturize the
skin. Moisturizing masks with the use of antioxidant water will have the special effect.
Pets and Plants – the pets will prefer the antioxidant water to usual tap or bottled water. The use of
water from the EMERALD for watering the indoor plants will be conductive to their rapid growth
and development.
3. METHODS OF WATER PURIFICATION AND ELECTRICAL TREATMENT
The EMERALD is highly productive and runs on cold tap water allowing you to get from 50 to 60
liters of drinking antioxidant water per hour.
Electrochemical activation technologies in the EMERALD allowed combining the high-
performance purification and the water treatment in order to restore its antioxidant properties.
The EMERALD provides the highest quality of drinking water by sequential combining the
electrical treatment of water in the electrochemical module and the use of auxiliary filter elements.
The main element of the EMERALD is the electrochemical module (Bakhir’s special flow-through
electrochemical modular element) in which the oxidative reactions take place on the anode and
reducing reactions on the cathode. The auxiliary elements in the device are the catalytic filter and
the electrokinetic filter. The absence of replaceable and short-life elements are identifying feature of
the EMERALD.
The oxidative reactions take place in the anode chamber of module where the destruction of the
microbes and microbial toxins as well as harmful organic compounds is occurred. In nature the
similar processes of antimicrobial protection namely phagocytosis have been occurring in all living
forms for millions of years without any failure occurrences.
In the cathode chamber the reducing reactions take place during which the water regains the useful
antioxidant properties (oxidation-reduction potential close to the internal media of the body). The

4
similar processes in nature occur during the contact of spring water with rocks as well as during the
phase transitions in the process of deglaciation.
The auxiliary catalytic filter consisting of the highest quality natural processed coal (grade A
hydroanthracite) serves for advanced water treatment from the oxidized organic and the
chloroorganic compounds (including the herbicides, pesticides, surfactants, phenols, antibiotics,
antidepressants, hormones).
The auxiliary electrokinetic filter consisting of the purest natural mountain quartz serves for the
advanced treatment of water from the mechanical impurities, heavy metals, iron, manganese and
hydrogen sulfide.
Useful information
The purification and electrical treatment of water in the anode and cathode chambers are
highly efficient and safe. The water treatment processes are identical to natural ones but they
are accelerated tens of thousands of times due to the use of the latest technologies and elec-
trochemical modules.
The catalytic and electrokinetic filters work in "purity". They are located after the anodic
destruction of microbes, microbial toxins and biofilms which significantly increases their
efficiency and service life. Therefore the filter elements in the EMERALD are protected from
the reproduction of microbes, fouling with the harmful biofilms and water contamination by
the microbial toxins!
The latest technologies used in the EMERALD allow you to get the clean and useful antioxi-
dant water while maintaining a neutral level of acid-base balance (pH level). The antioxidant
water with the neutral pH level is suitable for regular use in the composition of the usual die-
tary. Due to the similarity with the internal media of a human body such water is instantly
absorbed by the body and holistically restores it.

Main stages of water treatment in EMERALD device.
Fig. 1 Anode chamber of
module
Stage 1. Anode chamber of the electrochemical module
u The microorganisms, microbial toxins and biofilms are
destroyed in the water flowing through the anode chamber of
the electrochemical module;
u Oxidative destruction of the organic compounds such as
herbicides, pesticides, surfactants, phenols, petroleum products
and etc.;
u Deferrization of water is carried out with the transformation of
iron ions into a 3-valent form that is easy for mechanical
purification;
u Water obtains the properties of the active oxygen carrier.
Fig. 2 Catalytic filter
Stage 2. Catalytic filter
u At this stage the water is purified from a wide range of organic
and inorganic dissolved impurities that have undergone the oxidative
destruction in the anode chamber of the module;
u Water is being purified from free chlorine and chlororganic
compounds ;
u Improves the taste of water and eliminates the unpleasant
odors, due to the anodic removal of phenols and hydrogen
sulfide.

module
Stage 3. The cathode chamber of the electrochemical module
u Water treatment in the cathode chamber of the electrochemical
module imparts the antioxidant properties to the water reducing
the oxidation-reduction potential of water;
u Ions of heavy metal are converted to the insoluble hydroxides
and subsequently they are removed on the electrokinetic filter;
u At the same time all trace elements are preserved in water:
calcium, magnesium, sodium, potassium, lithium, fluorine,
iodine that are useful and necessary for a man;
u The properties is given to water as the active carrier of
hydrogen;

5. CONNECTION OF THE DEVICE
ATTENTION! This section describes the main method of connecting the EMERALD under the sink
recommended by the manufacturer. In the case of using an alternative method of connecting the
EMERALD it is necessary to make sure that the method chosen is not in conflict with the other
conditions of this Specification and the operating manual. In case of violation of the terms of
installation and operation of the EMERALD the warranty claims may be rejected.
EMERALD device location under sink.
The installation of EMERALD is carried out without
the fastening fixture on the bottom shelf of the sink cabinet
(Fig. 5) or is attached to one of its walls by the screws for
which the special hangers are located on the rear wall of the
device. To connect the EMERALD under the sink it is
necessary to use the connecting tubes (white ¼ tube made
of food grade plastic) and the parts included in the kit. Make
the connection in accordance with the diagram in (Fig. 7).
ATTENTION! Prior to start the installation of the
device you are requested to be sure to familiarize yourself
with the basic principles of connecting the white tube with
fittings described in the section “General rules for handling
quick-detachable joints such as John Guest®”
The fixed connection of the EMERALD requires the
certain skills in working with plumbing equipment. We
recommend using the services of authorized specialists of
EMERALD LLC, the representative of the dealer network
or the services of qualified plumber of the housing and
public utilities organization at your place of residence. Do
not install the device in the place where its maintenance will be difficult.
Prior to start the connections shut off the cold water tap and then open the cold water tap on the
kitchen faucet to relieve the pressure in the pipe. Avoid direct sunlight on the surface of the device
housing.
Having completed the connection of the device you should be sure that all connections were
secured and tightened. If you notice the water leakage in the connection joints of the tee (5), plastic
tubes with fittings (3), (4) or the water tap of drinking water (8) then disconnect and reconnect them.
During the installation it is necessary to pay the attention that the inlet and outlet tubes run freely
radially which exclude the fractures.

General rules for handling quick fittings like John Guest®.
The connection of the white ¼ tube to the fittings can be done manually or using the special
key included in the package. Quick-release joints of the John Guest® type allow, if it is necessary,
to carry out procedures for connecting / disconnecting the tubes and the fittings multiple times.
Important! Do not apply the
force when performing these
procedures! The correct
connections / disconnections
of tubes and fittings like John
Guest® do not require
excessive force!
To connect the tube to the fitting the following actions should be done:
u Insert the white tube until it stops in the hole of the fitting; If the connection is right then the
tube enters the fitting hole by 15-18 mm;
u Check the reliability of tube connection by countermotion of the tube. At the countermotion
of the tube the end ring (collet sleeve) of the fitting extends from the base;
u A retaining lock (blue / red clip) is inserted into the gap between the end ring (collet sleeve)
and the base of the fitting.
To disconnect the tube from the fitting:
u Temporarily remove the retaining lock (blue / red clip) from the fitting;
u Press the end ring (collet sleeve) of the fitting to the base of the fitting by the hand or with
special key and hold it in this position while pulling out the white tube;
u Pull the tube out of the fitting hole.

13
Connection of the device to the electric network.
The EMERALD device is connected to the electric network in several stages - see Fig. 13. First
you need to connect the power supply (adapter) to the network cable. Then you need to connect the
power cable to an electrical outlet and insert the plug of the power supply into the power socket of
the EMERALD device in the upper left corner of the side of the case.!
Important !!
It is forbidden to disconnect a working device (in OPERATION or FLUSHING mode) from the
network by pulling the plug of the power source from the device. This can lead to malfunctioning of
the device. Disconnecting devices from the power supply should only be done by disconnecting the
power plug from the outlet.

6. OPERATION OF THE DEVICE
Important! After connecting the EMERALD device it is necessary to familiarize yourself
with the operating rules.
Fig. 14. Internal elements of the EMERALD device
1 — inlet of unpurified cold tap water; 2 - output of purified antioxidant water; 3 - water flow
regulator; 4 - catalytic filter; 5 - electrokinetic filter; 6 - electrochemical module (the main
component of the EMERALD device); 7- monitoring and control unit; 8- hydraulic input for
citric acid washing solution; 9 – flushing mode on / off button; 10 - plug for flushing device
connection; 11- flushing device..
Important! Do not use for food or drinking purposes the first 30 liters of the purified
water immediately after connecting the device. In the case of prolonged downtime of the
device (more than 1 day) then the first 30 liters of purified water shall also be discharged.
When you turn on the EMERALD for the first time it is necessary to adjust the speed of
the purified water flow (see the “Setting the Flow of Water” section).
The device is intended for the purification and electrical treatment ONLY OF COLD
WATER FROM CENTRALIZED WATER SUPPLY SYSTEMS! When the OPERATION
mode of drinking water is activated then it is not allowed using warm or hot water through
the device as this may damage it.
Do not use the device for purification of microbiologically unsafe water or water of
unknown origin without the proper preliminary filtration and disinfection.

15
Supply of tap water.
To supply the tap water to the
device it is necessary to smoothly
open the ball valve on the tee - see.
(Fig. 15) in order to provide
running the cold tap water into the
device.
The vertical position of the valve
means there is no water supply.
Horizontal position of the tap
means that the water is supplied to
the device
Important! If there is high water pressure in the water supply system, it is not necessary to open the
valve completely. The partial opening of the valve on the tee will reduce the overall flow rate of
water and reduce the stress level on the hydraulic components of the device.
Water flow rate adjustment.
Adjust the speed of the water flow through the EMERALD using
the water flow regulator (see. Fig. 14 – “3” and Fig. 16) which is
located inside the device housing. This regulator allows you to set the
same water flow rate in the EMERALD regardless of the water
pressure in the water supply system. For high-quality purification and
electrical treatment the water flow through the device should be no
more than 1 liter / min. (60 liters / hour). If the flow rate of water is
slower in the device then the purification and electrical treatment are
better.
To regulate the flow rate of water it is necessary to do as follows:
u Unscrew the control valve retainer (flat metal nut) by turning it counterclockwise to the
required level.
u Rotating the control valve clockwise (reduction of the flow) or counterclockwise
(increase of the flow) it is necessary to set the required flow rate of water in the device
in the range of 50-60 liters / hour.
u After setting the required flow rate the retainer of the control valve (flat metal nut) shall
be tighten by turning it clockwise.
Attention! During the operation of the device the flow rate of the water can gradually decrease.
To restore the normal flow rate it is necessary to flush the device (see Section “MAINTENANCE
OF THE DEVICE”).

16
Operation of the device with the connection under the sink.
To start the operation of the device to the ball valve on the tee should be smoothly opened -see (Fig.
15).
u" To turn on the device, turn the handle on the purified water supply tap to the “open” posi-
tion so that cold water starts to flow into the device
u To turn off the device, the reverse action must be taken
!
Indication of the device.
The main indicator of the correct functioning of the EMERALD device
is the multifunctional LED integrated in the body of the device (see Fig.
17). Due to the presence of intelligent color indication of the LED, the user
can track all the most important parameters of the EMERALD device .
The multifunctional indicator allows one to evaluate: !
u"The resource of the device, after which it is necessary to flush the de-
vice (see Section “MAINTENANCE OF THE DEVICE”); !
u"The flushing process of the device, allowing the user to verify that all
stages of the device flushing are completed correctly; !
u"Correct connection of the hydraulic and electrical connections of the
device. !
!
Turning the handle on the tap for supplying purified water to the
“open” position will turn on the device and turn on the light indication in
one of the color modes corresponding to the state of the device. A detailed description of the various
modes of light indication is presented in the section "Monitoring of operating parameters".!
Fig. 17. Multifunctional
LED indicator of the device

17
Main operating modes
The EMERALD works in the semi-automatic mode. The built-in monitoring and control
device of the EMERALD allows the user to monitor the most important aspects of the device
status.
!
STANDBY mode.
In STANDBY mode, the device is connected to the mains and to the water supply device,
but is in the off state. The LED indication is off.
OPERATION mode.
Turn the regulator on the clean water tap to the “open” position. The LED on the device
will turn green to indicate that the device has entered into OPERATION mode.
If the idle time of the device in the STANDBY mode is more than 8 hours, then when it is
turned on, a green flashing LED lights up for 60 seconds, indicating that stagnant water must be
drained from the device during this time. After the stagnant water discharge time has elapsed,
the green LED turns on, indicating that the device has entered the full-fledged OPERATION
mode, and the drinking water quality has returned to optimal .
Some features of the OPERATION mode.
u If the STANDBY mode (idle) of the device is less than 8 hours then when it is turned on
the green LED will not be flashing which will indicate that water is not required to be
discharged from the device.
u After 8 hours of working in the OPERATION mode the LED will light in orange
indicating that the device is DESIRED to be washed with the acid solution.
u After 10 hours of working in the OPERATION mode the LED will light in red
indicating that the device SHALL be washed with the acid solution.
u Using the device in OPERATION mode for more than 10 hours without washing with
the acid solution is not limited by the device’s software but it is the violation of the
device’s operating conditions.
u The total active time of the working hours is the energy-independent characteristic and
that is when the power network is disconnected the active time of the working hours is
stored in energy-independent memory.
The visual method of monitoring the device’s operation is the availability of microbubbles
of hydrogen in the purified antioxidant drinking water.
The instrumental method of monitoring the parameters of purified antioxidant water is to
measure the parameters of pH and the reductive-oxidative potential (ORP) of purified water
with the use of appropriate instruments.

7. MAINTENANCE OF THE DEVICE.
To achieve the highest quality of purified water in the EMERALD as well as to ensure the
regulatory compliance of water quality the user shall regularly flush the device with the solution of
citric acid. With timely and uncomplicated maintenance your device will produce the highest quality
drinking water with excellent taste characteristics for many years.
Important! The EMERALD does not require the consumables materials and high-wear parts. The
electrochemical module and the auxiliary filtering elements (catalytic filter and electrokinetic filter)
do not require the periodic replacement while observing the operating rules described above.
Maintenance of the EMERALD including the regular flushing of the entire device (including the
electrochemical module and filter elements) with the solution of citric acid to remove the
accumulated impurities and deposits. The regularity of maintenance of the EMERALD depends on
the quality of the primary water, the usage rate and it is also based on user’s experience. At the
average when using the drinking water from the municipal water supply devices the maintenance of
the device shall be carried out at least once every 4 months or after 1,200 liters of the purified water
(whichever comes earlier).
The EMERALD automatically monitors the volume of purified water and it notifies you about the
need for flushing:
u After 8 hours of working in the OPERATION mode the LED will light in orange (≈480
liters of the purified water) indicating that the device is DESIRABLE to flush with the citric
acid solution.
u After 10 hours of working in the OPERATION mode (≈ 600 liters of the purified water) the
LED will light in red indicating that the device MUST be flushed out with the citric acid
solution.
Important! The flushing frequency is calculated for the tap water with average salinity
of 200 ppm. For regions with the excessive water hardness (mineralization of more than 350
ppm) it is necessary to use the water softener filter (purchased separately) or to perform more
frequent flushing of the device with the citric acid. The regularity of the flushing in this case is
determined in situ depending on the hardness of the supplied tap water, the operating mode of
the device and the organoleptic qualities of the purified water.
* If during the operation of the device after a series of flushes it seems to you that the taste of
purified water does not suit you it is possible to purchase and replace the filter elements of the
device. The order can be placed with your nearest dealer or at the official website of the
manufacturer.

Maintenance of the EMERALD is carried out in accordance with (Fig. 18) in the following order:
Preparation of citric acid washing solution
To carry out the flushing procedure for the EMERALD it is necessary to prepare 1 (one) liter of
citric acid washing solution in the tank of the flushing device (Fig. 18 – “5”). The flushing solution
of citric acid is prepared on the basis of 200 grams of the citric acid and a half liter of water. Citric
acid crystals are recommended to be diluted in hot water but the flushing is carried out by the
solution with temperature of 60-70 °C (not hotter!).
Important! It is not allowed flushing the EMERALD by the citric acid solution over
70°С. This may damage the device! Claims in this case will not be accepted. For accurate
determination of the temperature of the flushing solution you are requested to use the
temperature control instrument.
