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
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.

4
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 ac-
celerated tens of thousands of times due to the use of the latest technologies and electrochemical
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 ef-
ficiency 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 antioxidant
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 dietary. 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.

6. OPERATION OF THE DEVICE
Important! After connecting the EMERALD device, it is necessary to familiarize yourself
with the operating rules of the device.
!
Important! Do not use the first 30 liters of purified water immediately after connecting the
device for food purposes . For prolonged shutdowns of the device (more than 1 day), the
first 30 liters of purified water should also be drained .
The device is designed for cleaning and electric processing ONLY COLD WATER FROM
SYSTEMS OF CENTRALIZED WATER SUPPLY! In the drinking water preparation mode,
do not pass warm or hot water through the device, as this may damage it.
Do not use the device for cleaning microbiologically unsafe water or water of unknown
origin without proper pre-filtration and disinfection.
Cold tap water supply to the device
Fig. 10. Water supply using the regulator on the diverter.!
To enable the device in the OPERATION mode, it is necessary to open the cold water supply on
the tap, and then smoothly turn the regulator on the diverter to a horizontal position ( see Fig. 10) so
that cold tap water begins to flow into the device.!
!
- The vertical position of the regulator on the diverter - water goes to the device;!
- The horizontal position of the regulator on the diverter - the water drains into the sink.!
!
The device turns on automatically as soon as water begins to flow into it. When the device is
switched on in the OPERATION mode, the multifunctional LED lights up in one of the corresponding
modes.!
!
Turning off the device also occurs automatically immediately after the water supply stops. When
the device is turned off, the multi-function LED turns off.!

13
LED indication of the device.
The main indicator of the proper functioning of the EMERALD device is a multifunctional LED
integrated into the device housing. The multifunctional indicator allows you to evaluate:!
u"Device resource, after which it is necessary to flush the device; !
u"Device flushing process, allowing the user to verify that all stages of the FLUSHING mode
are correctly completed ; !
u"Correct connection of the hydraulic and electrical connections of the device. !
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.
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 normal .
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 Unit 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.

uUser can always pause the automatic FLUSHING mode and start it again by repeated pressing of
the button ( Fig. 11- “ 8 ” ). This function allows the user to suspend the FLUSHING mode if there
are problems with pumping the washing solution into the device and resume this mode again. !
!
uFLUSHING mode is non-volatile and has priority. That is, when the network disappears and when
it reappears, the device will automatically enter the stage of the FLUSHING mode from which it
was removed by disconnecting the network. It protects the user from the risk of accidental inges-
tion of a citric acid solution in the body if the FLUSHING mode is violated. !
!
u"Important! If during the FLUSHING of the device there were any malfunctions that could interrupt
the course of the FLUSHING mode, please repeat the FLUSHING procedure before using the
device. If faults are detected during the FLUSHING mode, it is necessary to additionally make
sure that the washing solution was successfully flushed with tap water from the device
for 10 minutes before starting to use the device in normal mode. !
!
Important! To increase the useful life of the flushing device, it is suggested that after carrying
out maintenance procedures user should rinse thoroughly the intake part of pump, the holding tank for
flushing solution and connecting hoses of the flushing device with warm tap water so as to wash out
residues of the citric acid crystals. After flushing, all elements of the flushing device must be dried
and removed to dry and clean place while waiting for the next flush. The FLUSHING procedure of
the main elements of the flushing device must also be repeated at the beginning of future flushing
procedures to ensure the smooth operation of the device.

residues of citric acid in the citric acid
supply hose (Fig. 11 - “12”)
2. The citric acid supply hose is
pinched (Fig. 11 - “12”) .
3. It is necessary to suspend the
FLUSHING mode if the washing so-
lution is not pumped into the device,
but the FLUSHING program is al-
ready running.
1. Rinse with warm tap water the
flushing solution supply hose and the
lower intake part of the pump for 2-
3 minutes. Then repeat the FLUSHING
