pH Reagent Liquid Precautions
Do not expose the pH measuring reagent to extreme heat, flames
or fire. It is combustible.
Do not drink the pH reagent liquid, put it in the eyes or apply to the body.
- If the liquid is ingested, induce vomiting immediately and call
a doctor.
- If the liquid gets in the eyes, flush immediately and thoroughly
with cool water; call a doctor.
- If spilled or dropped on your body, wash if off immediately.
Make sure to keep the pH reagent liquid tightly closed and out of the reach of children.
Some helpful tips
For storing your alkaline water, glass or ceramic is best. Always try and
keep your stored water cool and away from direct sunlight.
You can use plastic, but only use lexan (number7) or poly bottles
(Nalge type). It is always best fresh out of the machine and ideal
if consumed on a day-today basis.
Do not store alkaline water in stainless steel, bronze or
aluminum containers.
Save the box and Styrofoam your ionizer came packed in.
This will help if your ionizer needs to be transported at a later date.
Do not use an ionizer downstream of a sodium-based ion exchange
softening system or Reverse Osmosis system without first consulting
with your dealer.
During Use
Do not run hot water through your ionizer.
Do not clean by pouring water over or spraying the ionizer.
Do not close, bend, pinch, press or otherwise obstruct
output ports or hoses.

How to Use
1. POWER UP YOUR IONIZER.
- Depress the black power button located on the back of the ionizer to the
"ON" position.
- The black power button is ALWAYS left on. Your ionizer will "go to sleep" in
between uses and
"wake up" when it detects water flow again. It will always return to your last
selected setting.
- You will hear a single chime and the display panel will illuminate for 2-3 seconds.
- With the power on and the display panel dark, your ionizer is now in standby mode.
2. START WATER FLOW THROUGH YOUR IONIZER
a. SET THE FLOW CONTROL VALVE - This control is on the front of machine
and has an "ON" and "OFF" position. Try initially setting this half way
between "ON' and "OFF".
This control WILL DIRECTLY impact the performance of your ionizer.
A slow flow will yield higher pH; a fast flow will yield lower pH.
b. Turn on your water faucet. Turn the lever to until you "divert" the water through your ionizer.
c. Get the feel for the difference in flow rates by adjusting FLOW CONTROL VALVE from a slow
trickle to the fastest flow. When you begin ionizing the water, start with it in the medium range
and adjust faster or slower as necessary to achieve optimum results.
TO SELECT ALKALINE WATER
1. With water running through the ionizer:
2. Depress the "ALKALINE" button to select the desired setting from 1 - 4.
You will hear voice confirmation that "Alkaline water" has been selected, and the
LED Control Panel will be back-lit. The Alkaline Water Indicator
will light showing the level you have selected.
3. Note: Your ionizer will always "remember" the last setting used. If the previous selection was
Alkaline Level 2, when you start the ionizer the next time, your ionizer it will automatically
process at the same Alkaline Level 2.
4. To select a different level, depress the "ALKALINE" button to move to next level until the
desired setting level is achieved. The Alkaline Water Indicator will change accordingly.
IMPORTANT NOTES:
IMPORTANT NOTES:
If you have never consumed alkaline water - do not use a setting higher than 1 to begin with.
Let your body adjust slowly and naturally for 4-7 days. After this initial adjustment period,
you may gradually increase the alkalinity of the water.
pH levels will vary according to the minerals present in the source water and water flow rate
through your ionizer.

After the adjustment period you can drink the water at this next level.
This level is also great for cooking rice and other grains
- fluffier and great tasting!
You can get alkaline/acidic electrolyzed-reduced water by electrolyzing the water after filtering
impurities. Alkaline reduced water is the optimal water for health because it is rich in minerals
including calcium. Acidic water is good for skin.
Some people like this for drinking though it can start to taste strong
It is superb for making tea or coffee as it enhances the taste and reduces
bitterness!
Generally most people find this very strong tasting and with powerful
detoxifying effects.
Great for boiling vegetables! Alkaline water will eliminate the bitter taste
and brings out more of their natural color.

Some uses for the different levels of Alkaline Water
The Acid water has both antiseptic and antibacterial properties.
It also has an astringent effect and can be used for cosmetic purposes.
For initial consumption period
(4-7 days). Let your body adjust slowly to the increase in pH.
Many people find that this lower level is actually perfect for them.
What would I use the Filtered Water for?
The pH of Purified water is neither raised nor lowered and would be the
same as your tap water.
This water is simply cleaned of impurities by the advanced filtration system.
You can use it both as drinking water and to take medications with.
Some uses for the different levels of Acidic Water
Precautions for use of Alkaline water - don't develop a "drinking" problem!
Use it while brushing your teeth,
gargle with it and use it as a
natural mouth wash!
It is an excellent astringent;
use it for washing your face or
as a natural after shave.
In the kitchen use it to help
clean kitchen utensils.
This setting has sterilizing
properties - use it to sterilize
cutting boards,
dish towels etc…
If you have never consumed alkaline water - do not use a setting higher than 1 to begin with.
Let your body adjust slowly and naturally for 4-7 days. After this initial adjustment period, you
can gradually increase the alkalinity of the water.
Do not take medications with alkaline water. Take medications only with purified water.
Consult with a physician before drinking alkaline water if you have:
- Chronic disease
- Are currently under medical treatment
Do not drink alkaline water if you have achlorhydria.
Consult a physician before using acidic water if you have:
- Sensitive skin
- Allergies
Only use potable drinking water in your ionizer.
Poor water quality may have negative effects on your health and your ionizer! Most municipal
water sources will be fine in your ionizer.
Well water and water from smaller systems should be checked, and may require pre-filtering.
Your ionizer is not under warranty for any damage or required cleaning caused by hard water
deposits.

Stop the water flow prior to calcium replacement.
- Water will overflow if you open the calcium cap while water is coming out.
2
Unscrew the cap to the left and remove.
-The first time you remove it the cap may be tight.
Use a butter knife to work it free.
3
Please remove the used up calcium basket from calcium chrome cap.
The beads never completely disappear it's the calcium coating
on the beads that slowly releases into the water.
Beads will release calcium for about 1-2 months depending
on amount of use and pH of water.
4
Wash the calcium chrome cap in clean water.
5
Please remove the plastic cap from new calcium cartridge.
Please replace the new calcium cartridge and close the cap.
NOTE :
If you do not remove the plastic cap of a calcium cartridge,
will crack the internal calcium port or leak the internal.
6
Insert the basket into the calcium port and twist the cap closed.
WARNING! Water will overflow if you do not close the cap tightly.

How to Replace the Filter
Please replace filter when any one of the flowing occur:
- When severely polluted water has been run through the
ionizer and filter
- Excessive odor in output water and/or severely decreased
flow rate
- After prolonged period of inactivity of over 30 days
When the digital filter life indicator reaches '9999' it is time to replace your filter.
You will also want to replace your filter if any of these situations occur:
- Severely reduced flow rate - slower than usual even with full flow on the control valve.
- Abnormally bad taste - usually due to a sudden change in quality of source water.
- A period of inactivity of over one month - for instance an extended vacation.
Check for leaks by running water through your ionizer before replacing the
housing cover.
Open the filter housing cover.
-Push in on the plastic ridges in the center of the
filter housing cover on the side while pulling the
door out and to the left. Swing door out and remove it.

Flush out the GAC carbon dust.
- The water will initially come out discolored (light to charcoal gray) due to carbon dust
in the new filter. This is not harmful and is typical of all GAC filters.
Allow the water to flow for 2-3 minutes in the "Purified" mode and this will flush all the
carbon dust.
How to Replace the Filter
Insert the new filter into the compartment.
-Remove the plastic caps covering both ends of the new filter.
-Seat the large opening on the bottom of the filter cartridge onto the base.
- Push the filter down and into the housing compartment ensuring the opening at the top
of the filter is seated properly into the fitting at the top of the housing
IMPORTANT! Stop water flow prior to filter replacement.
Replace the filter housing cover.
Remove the expired filter.
-Taking hold of the filter securely with you right hand, press the
filter firmly down against the spring loaded mechnism to disengage
the top of the filter and then lean the filter out toward you and lift up
to remove it.
-The upper part of the filter is separated from housing by pressing
firmly down. Once you have engaged the spring loaded mechanism,
you can then easily remove the filter from the main body by
leaning the filter out toward you and life up to remove it.
Reset the filter life indicator.
- With your ionizer in standby mode (water not runni ng through the ionizer)
press the "Reset" button located at the top of the filter housing compartment
until the counter resets to 0000.

Calcium:
It slightly increases the alkaline mineral content in your water. It improves water taste and odors,
You get calcium on tap!
Tourmaline:
Tourmaline emits Far Infra Red (FIR) energy naturally. FIR produces well documented health
benefits and it also has an amazing effect on water.
The Biostone contains the semi -precious gemstone tourmaline in ceramic form,
so you get FIR on tap!
Non-woven fabric filter
Filters out sediment and particulate.
Granular Activated Carbon (GAC) :
The workhorse of the filtration media. GAC is especially effective at removing chlorine, its odor
and taste, agricultural chemicals, phenol, trihalomethane and other chemical contaminants.

Faulty PCB
(Printed Circuit Board)
Immediately unplug the unit
and contact your dealer to
arrange service.
pH test shows alkaline water
color as neutral (7) while
acidic water color gets
yellow (6). This is normal
if initial pH is 6.5
Faulty or evaporated reagent:
alkaline / acidity are always
produced in inverse proportion.
Therefore, showing an acidic
color means inversely that
alkaline water has to be
generated from the unit.
Lack of alkaline color can
result from a chemical
reaction where carbonic
acid in water evaporates
some test reagent elements.
Test pH value on level
3 or 4 water;
replace reagent.
Power supply is suddenly
cut off while operating the
unit.
Elevated level of salt in the
water or high TDS; extended
operation at high pH;
sudden flux in electrical
current. In these cases your
machine will shut down
automatically to protect the
electrodes and circuitry.
Wait - the unit will become
operational again after about
one hour. Your ionizer has a
safety mechanism built-in to
protect the electrodes and
circuitry. This mechanism will
shut the ionizer down
automatically. This mechanism
protects the unit from overuse
or excessive electric current.
Low output of alkaline water
from the unit.
Filter is clogged. Premature
clogging may be caused by
sudden drop in water quality and
an influx of sediment or other
contaminants, which stress
the filter.
Low pressure in your household
plumbing.
The input hose is bent, kinked or
otherwise restricted.
Replace your filter.
Clean Pre-filter
Ensure water supply valves are
fully open. The water pressure
in house may be too low.
Straighten the bent hose.
Strange smell from
Alkaline water.
Expired filter from ordinary use
or premature clogging due to
flux in water quality.
Sudden flux in water quality with
elevated level of Choline
(not Chlorine). Elevated Choline
levels are observed in some
areas during summer months.
These levels fall within safe
drinking water standards, yet
will cause a reaction with ionized
water causing a unique smell.
Replace your filter.
Select lower pH level (1-2).
If still present, filter replacement
may be necessary.
Water appears milkish;
white snow like particles
in the bottom of your glass.
You have high hardness (calcium
primarily) in your water. The white
is extracted CaCO3 (Calcium
carbonate). After Co2 in water is
bonded with Ca where elevated
levels of CO3 exist in your water.
In water where elevated levels of
CO3 exist, what you see after
ionization is Co2 in the water
bonded with Ca.
This is calcium! It is not only
harmless, but actually good for
you. Remember the ionizer
separates and condenses the
alkaline minerals and this is what
you are seeing. You can lower
the setting (1-2) and reduce
this effect. Typically this only
occurs in hard water areas.
At first no smell, but then
smell from the alkaline
water about one hour after.
Your water bottle or receptacle
is foul and needs cleaning.
