and you have also taken a very important step towards improving your health!
EMERALD HOME 250 SPA Device is a professional compact system to produce from ordinary
tap water in flow-through mode drinking water with antioxidant properties (catholyte), purified from
microbes and microbial toxins, iron, manganese, hydrogen sulfide, heavy metal ions and harmful
organic compounds (including herbicides, pesticides, hormones, antibiotics, antidepressants).
Antioxidant water enriched with molecular hydrogen using electrochemical activation (ECA)
technology, has a beneficial effect on the entire body, normalizing metabolism and the functioning of
internal organs, cleansing them from toxins, strengthening the immune system, and toning up the
whole body.
The peculiarity of the EMERALD HOME 250 SPA Device is an increased productivity of 250
l/h, which allows using this equipment not only for obtaining pure antioxidant water for drinking
purposes, but also to carry out antioxidant water therapies in the form of baths or showers in the field
of balneotherapy procedures for the treatment, prevention and restoration of impaired body due to
oxidative body stress elimination. Antioxidant drinking water effectively neutrale toxic forms of
active oxygen, including free radicals, and restores the optimal balance of oxidative and reduction
reactions (REDOX status of the body) in the intercellular fluid and inside the cells, which is a
prerequisite for the correct functioning of all fundamental vital processes of the body.
EMERALD HOME 250 SPA Device produces cold or warm pure electrochemically activated
catholyte from ordinary tap water in a flow-through mode and are used in resorts and sanatoriums,
medical and rehabilitation centers as well as in fitness, spa and massage centers for providing safe and
effective antioxidant drinking water.

2. INFORMATION ABOUT ANTIOXIDANT WATER - CATHOLYTE
Theoretical concepts
Electrochemically activated catholyte is antioxidant water with pronounced electron-donor
properties. Catholyte is obtained from fresh water, in which powerful unipolar action (in the double
electric layer at the cathode of the electrochemical module) causes formation and storing of metastable
products of cathode electrochemical reactions, in particular, molecular ions НО2¯, О2¯, ОН¯.
Electrochemically activated catholyte exhibits an electron-donor ability, i.e., it is a strong
reducing agent and reduction catalyst in various physicochemical reactions, including biochemical
ones. Catholyte provides for effective neutralization of toxic forms of active oxygen, including free
radicals, and restoration of the optimal balance of oxidative and reduction reactions (REDOX-status)
of the body in the intercellular fluid and in cells, which is directly related to the correct course of all
fundamental life processes of the body.
Practical application of catholyte
Electrochemically activated catholyte is one of the best antioxidants. Antioxidants found in
foods, vitamins or dietary supplements do not give a person proper protection. Due to their large size,
their molecules are not able to penetrate into cells and neutralize toxic oxidants (including free
radicals).
Antioxidant water from EMERALD HOME 250 SPA Device has a beneficial effect on the entire
body, normalizing metabolism and the functioning of internal organs, cleansing toxins, and also
strengthening the immune system, improving memory and toning up the body.
Antioxidant water has a positive effect on the body when consumed as part of a regular diet and
protects against the action of strong toxic oxidants. The mechanism of action of antioxidant water is
based on the transfer of protective electron-donor properties to the body's internal environments,
helping the body's internal antioxidant system to cope with excessive exposure to various oxidative
factors of technogenic origin (polluted air, poor quality of drinking water and food, stress and
overwork, alcohol and cigarettes). Catholyte stimulates tissue respiration, which enhances the action
of vitamins and chemical antioxidants in the body. Antioxidant water also weakens the effect of
ionizing radiation, i.e. exhibits radioprotective properties characteristic of antioxidants. Antioxidant
water improves passive immunity and general condition of the body, improves the functioning of the
gastrointestinal tract and urinary tract, and normalizes blood counts.
Water treated in EMERALD HOME 250 SPA Devices, like any natural antioxidant water, retains
its electron-donor properties for no more than a day from the date of obtaining. After this period, the
redox potential (ORP) of the treated water returns to the original ORP values of non-activated water,
on average, in the range (+100) ÷ (+250) mV, SCE. When boiling, the electron-donor properties of
antioxidant water also decrease. Antioxidant water produced in the EMERALD Device should be
stored for no more than a day in glass containers with a closed lid, away from direct sunlight and heat
sources.

3. ANTIOXIDANT WATER APPLICATION METHODS
Main application methods
Consuming as part of a normal diet - The human body is more than 70% water. Water plays
the most important role in the life of the human body. An adult needs to consume about 2 or 3 liters
of water per day to maintain the normal functioning of the body.
Cooking - food on antioxidant water is cooked faster and retains more beneficial properties.
Antioxidant water is great for soaking fruit, vegetables, fish and meat - due to its strong extraction
properties, catholyte actively removes harmful chemicals from foods, such as growth hormones and
antibiotics.
Making drinks - in addition to drinking antioxidant water from EMERALD Device, you can
enhance the antioxidant effect due to synergistic phenomena and make antioxidant drinks using
natural antioxidants - freshly squeezed juices of carrots, apples, various berries, by adding antioxidant
water from EMERALD Device to them. Herbal teas prepared with this water acquire a special taste
and aroma. Ice cubes made of frozen antioxidant water will give the drink an extra benefit.
Air humidification - antioxidant water is useful in the form of a mist when used in humidifiers.
Humidified air with microdrops of antioxidant water, having the properties of a reducing agent,
produces a beneficial effect on the respiratory and cardiovascular systems, prevents asthma attacks
and allergic diseases.
Cosmetic purposes - for cosmetic purposes, antioxidant water is useful for washing, in the form
of ice cubes for wiping the face, or in the form of a spray to moisturize the skin. Moisturizing masks
based on antioxidant water will have a special effect.
Pets, plants and seeds - pets will prefer antioxidant water to regular tap or bottled water. The
use of water from the EMERALD Device for watering houseplants or germinating seeds will promote
their accelerated growth and development.
Important!
The latest technology in the EMERALD Device allows you to get clean and healthy antioxidant
water while maintaining a neutral acid-base balance (pH level). pH neutral antioxidant water is
suitable for regular consumption as part of a normal diet. Due to the similarity with the internal
environment of a human, such water is instantly absorbed by the body and holistically restores it.
EMERALD HOME 250 SPA Device is not a medical device. Before using catholyte for
preventive or therapeutic purposes, consult a specialist. The information on the properties and methods
of using catholyte presented in this section is for reference only and does not apply to medical reports.

Antioxidant water therapy in the form of baths and showers
An advanced direction in the field of balneotherapy is antioxidant (electron-donor) water therapy
in the form of baths and showers using electrochemically activated catholyte produced from fresh
drinking water.
Antioxidant water therapy in the form of baths or showers based on purified electrochemically
activated catholyte produced from fresh water is an effective and safe method for regulating the
REDOX status of the internal environment of the body. Antioxidant water therapies enable to restore
the body at the cellular level, normalizing the balance of oxidative and reduced chemical compounds
in the extracellular and intracellular fluids, which is a prerequisite for the correct functioning of all
fundamental vital processes of the body.
The effectiveness of this procedure is due to the fact that when a person is immersed in a bath
with catholyte, about 67 % of the skin gets into direct contact with the electrondonor liquid medium
and the negative electrostatic charge of activated water is transferred into the blood through the skin.
Taking into account that the blood flow through the skin areas which are in contact with the catholyte
is approximately 0.3 l/min and the total blood flow in the body is about 5.5 l/min, one will obtain the
following result: during a 7 minute antioxidant bath therapy, approximately 33 % (about 1.5–2 liters)
of the total circulating blood volume in the body is subjected to percutaneous electrochemically
activated catholyte treatment. Moreover, one could achieve even better results by means of combining
courses of antioxidant baths or showers with courses of antioxidant water drinking which will result
in synergistic effect.
1
It is important to note that only electrochemically activated water or aqueous solutions have the
necessary properties for carrying out effective antioxidant water therapies. The following experiments
have shown that the ORP value of physiological solution in sealed containers made of glass and
fluoroplastic (dielectrics), after immersing the ampoules in the cathode chamber of a working
diaphragm electrolyzer with exposure for 30 minutes, significantly changed into the negative values
zone (< 0 mV). That is, the phenomenon of a contactless electrochemical activation of the solutions
inside the sealed ampoules that do not conduct electric current was detected. The relaxation of negative
ORP values in the ampoules to an equilibrium state took around 2 hours. However, in the case of
immersion of the same sealed glass and fluoroplastic ampoules with physiological solution in non-
activated strong alkali solutions, the ORP inside the ampoules did not change. Thus, non-activated
alkaline solutions do not transfer reducing properties through non-conductive materials. Accordingly,
simple water alkalization for sanitary bath therapies, for example with baking soda, does not give the
desired effect.
Effective electron-donor water therapy in the form of baths or showers directly depends not only
on the methodology of carrying out this procedure, but also on the quality of the equipment used for
producing electrochemically activated catholyte.
The water treatment scheme in EMERALD HOME SPA Devices is based on authentic MB-11
electrochemical modules and allows for producing up to 250 l/h of cold or warm electrochemically
activated catholyte from ordinary tap water in a flow-through mode with ORP value in the range of (-
150)÷(-450) mV, while maintaining a neutral pH level in the range of 7.0÷8.5 units. Preservation of
the neutral acid-base balance of the catholyte in line with notable ORP shift towards reduction values
is an important factor for producing antioxidant water similar in ORP and pH values to biological
fluids of the body, making antioxidant water therapies in the form of baths and showers safe and
effective.

At the same time, the electrochemically activated catholyte in EMERALD HOME SPA Devices
undergoes a complex scheme of water purification from microbes, microbial toxins, biofilms, heavy
metals, iron, manganese, hydrogen sulfide, harmful organic compounds, free chlorine and
organochlorine compounds, turbidity and impurities, while preserving all the necessary useful
microelements in the purified water.
Summing up, the water treatment method in EMERALD devices is environmentally friendly and
safe, since the electrochemical modules exchange only electrons with water, taking them away from
the water in the anode chamber, where oxidation reactions take place and the water is enriched with
oxygen, and loading electrons into the water in the cathode chamber, where reduction reactions take
place and the water is enriched with hydrogen. Therefore, the electrochemically activated catholyte
from EMERALD devices is in fact pure drinking water with pronounced electron-donor (antioxidant)
properties which meets all the main Russian and international requirements for drinking water,
including the international WHO recommendation «Guidelines for drinking-water quality».
Important! EMERALD HOME 250 SPA Device is not a medical device. Before using catholyte
for preventive or therapeutic purposes, consult a specialist. The information on the properties and
methods of using catholyte presented in this section is for reference only and does not apply to medical
reports.

4. PRINCIPLES OF WATER TREATMENT
The EMERALD Device has high performance and runs on cold or warm tap water (not higher
than 45 °С), producing up to 250 liters of purified antioxidant drinking water (catholyte) per hour.
EMERALD Device ensures high quality of drinking water purification due to the consistent
combination of water activation in electrochemical modules and the use of auxiliary environmentally
friendly filter elements. The main elements of the EMERALD Device are 6 (six) MB-11 type
electrochemical modules (diaphragm flow-through electrochemical Bakhir modular elements), in
which oxidation reactions take place at the anode and reduction reactions at the cathode (Fig. 1).
Auxiliary elements in the Device are a catalytic filter and an electrokinetic filter. A distinctive feature
of EMERALD Device is the absence of replaceable and wear parts.
All processes of water purification and electrical treatment in Device are as close as possible to
what happens to water in wildlife. It has become possible to repeat the natural processes of water
purification and treatment due to the creation of reliable electrochemical modules, which are the main
elements of the system. The modules consist of two flow-through chambers: anode and cathode. It is
in these chambers that, under the influence of a positive current on the anode and a negative current
on the cathode, the water treatment processes suggested by nature are reproduced.
In the anode chamber of the module oxidative reactions take place, during which microbes and
microbial toxins are destroyed. In nature, a similar process of antimicrobial protection, phagocytosis,
has been occurring in all living organisms for millions of years without any failures. Also, in the anode
chamber, harmful organic compounds (including hormones and antibiotics), iron, manganese and
hydrogen sulfide are oxidized.
In the cathode chamber, reduction reactions take place during which water again acquires useful
antioxidant properties due to enrichment with hydrogen. In nature, similar processes occur during the
contact of spring water with rocks, as well as during phase transitions in the process of melting
glaciers. Also, cathode water treatment can effectively remove heavy metals.
The auxiliary catalytic filter consisting of natural coal of the highest standard (grade A
hydroanthracite) is used to purify water from oxidized organic and organochlorine compounds
(including herbicides, pesticides, surfactants, phenols, antibiotics, antidepressants, hormones).
The auxiliary electrokinetic filter, consisting of the purest natural mountain quartz, is an
environmentally friendly analogue of a mechanical fine filter and serves to purify water from
mechanical impurities, heavy metal hydroxides, oxidized forms of iron, manganese, hydrogen sulfide.

Useful information!
All water purification and activation processes in EMERALD Devices are as close as possible to
what happens to water in living Nature, since the mechanism of fresh water purification in Nature is
represented by two main processes: redox reactions and filtration.
Therefore, in EMERALD Devices the combination of electrochemical anode and cathode water
treatment with environmentally-friendly filter elements requiring no replacement provides deep water
purification from microbes, microbial toxins, biofilms, heavy metals, iron, manganese, hydrogen
sulfide and harmful organic compounds.
The safety of water treatment using ECA technology is ensured by the complete absence of any
chemicals in EMERALD Devices. MB-11 type electrochemical modules in which electrical treatment
of water takes place, exchange only electrons with water, taking them from the water in the anode
chamber, where oxidative reactions take place and the water is enriched with oxygen, and introducing
the electrons into the water in the cathode chamber, where reduction reactions take place and the water
gets enriched with hydrogen.
This allows the catalytic and electrokinetic filters to work in «clean condition». In the hydraulic
scheme of the EMERALD Device, they are located after the anode destruction of microbes, microbial
toxins and biofilms, which significantly increases their efficiency and service life. Therefore, the filter
elements in the EMERALD Device are protected from microbial growth, fouling with harmful
biofilms and water pollution by microbial toxins!
It is important to note that EMERALD Device has no consumables or wear parts.
Electrochemical modules and auxiliary filter elements (catalytic filter and electrokinetic filter) do not
require periodic replacement under the operating conditions described in this Operating Manual.

General rules for handling John Guest® type quick-release fittings
Connection of white tubes 1/2" and 1/4" with fittings is done manually. John Guest® type quick-
release fittings allow, if necessary, for carrying out tubes and fittings connecting/disconnecting pro-
cedures repeatedly. When properly connected, the tube enters the fitting hole by 15-18 mm. The cor-
rectness and reliability of the connection is checked by the return movement of the tube after connect-
ing to the fitting. With a force of 8–10 kgf, the tube should not be pulled out of the fitting.
Important! Do not apply force when performing these procedures! Proper
connection/disconnection of John Guest® tubes and fittings does not require excessive force!

CONNECTING TUBES AND CLOSING PLUGS TO QUICK-RELEASE FITTINGS.
Connecting tubes or plugs to fittings is
to be performed in accordance with Fig.
7.2:
u Insert the tube by hand into the
fitting hole (1) as far as it will go.
When properly connected, the tube
enters the fitting hole by 15-18 mm;
u Insert a fixing clip-lock (2,3) into
the gap between the sliding collet
ring and the base of the fitting;
u Check that the connection is secure
by moving the tube back. With a
force of 8 to10 kgf, the tube should
not be pulled out of the fitting.
DISCONNECTING TUBES AND
CLOSING PLUGS FROM QUICK-
RELEASE FITTINGS.
Disconnecting tubes or plugs from
fittings is to be performed in accordance
with Fig. 7.3:
u Remove the fixing clip-lock from
the fitting (2);
u Using a hand or a special wrench (9,
Tab. 5), press the collet ring of the
fitting to its base (3);
u While holding the collet ring of the
fitting in the pressed position (3),
pull the tube or plug out of the
fitting by hand (4).

Connecting the EMERALD Device
This section describes the basic EMERALD Device connection method recommended by the
manufacturer. If you use an alternative method of EMERALD Device connecting, you must make
sure that the method you choose does not contradict other terms of this Operation Manual. In case of
violation of the terms of EMERALD Device installation and operation, warranty claims may be
rejected.
The Device is attached to the wall using screws and dowels, for which there are special hangers
on the rear wall of the Device casing. If necessary, to strengthen the structure, it is possible to
additionally mount a horizontal support from below the Device, on which it will be possible to place
the Device and, after that, fix it to the wall through hangers using screws or anchor bolts.
To connect the EMERALD Device to the water supply line, use a diverter nozzle with a set of
adapters (4, Table 5), which is directly connected to the faucet spout instead of the standard aerator.
As an alternative, it is possible to connect the Device to the water supply line through a t-bend with a
ball valve (Add. 1, Tab. 6), which is installed in the gap in the water supply line (not included in the
standard delivery set).
To start using the EMERALD Device, it is necessary to connect the Device using connecting
hoses (white tube 1/2" in size and the parts included in the delivery package, in accordance with the
main connection diagram in Fig. 8. The white tube is cut into the required lengths already at the
installation site. In domestic conditions, you can cut the tube with a regular kitchen or stationery knife
using a cutting board. To fix the tubes when laying them, use the sliding tube holders from the delivery
set (8, Table 5).
Keep the tubes and plugs remaining after the Device installation! You will need them to carry
out the FLUSHING mode (see DEVICE MAINTENANCE section), as well as to transport the Device.
Fixed connection of EMERALD Device requires certain skills in working with plumbing
equipment. We recommend using the services of authorized specialists of the company EMERALD
ECOTECHNOLOGIES LLC, a representative of the dealer network or the services of a qualified
plumber of the housing and communal services organization at your place of residence. Do not install
the system in a place where its maintenance would be difficult. Do not install the equipment in a place
where the Device casing will be exposed to water or direct sunlight. Before starting the connection,
shut off the cold and hot water tap, and then open the cold and hot water valves on the faucet to relieve
pressure in the system.
Important! During installation, pay attention to the inlet and outlet tubes passing freely along
radii to exclude kinks. To avoid excessive tube pressure on the Device water inlet and outlet fittings
(5,6, Fig. 8), evenly fix the water inlet and outlet tubes during installation using the sliding tube holders
(8, Table 5). Threaded connections without sealing gasket must be sealed (e.g. with plumbing thread).
To enhance the antioxidant properties of purified water, as well as to improve its organoleptic
qualities, it is possible to use a replaceable activated carbon post filter which is installed in Slim Line
10" flask (Table 6. Add. 2,3) after the EMERALD HOME 250 SPA Device. The post filter connection
diagram is given in Appendix №1.
