Safety Precautions
If a break down occurs, do not make a repair by yourself. Contact the place of purchase or A/S center.
Electrical power precautions
If your ionizer becomes submerged
in water, unplug the power cord from
the wall BEFORE removing the
ionizer from the water.
Failure to do so may cause electric shock!
NEVER attempt to repair or service the unit yourself.
Contact your dealer.
Attempting to do so will void your valuable warranty!
Do not use your ionizer at voltages other than specified
(AC 110V FOR USA).
Use a GFI outlet. Do not plug in your ionizer where it
will exceed the rating of outlet or electric wiring.
Failure to do so can result in fire, injury and/or
damage to yourself, wiring or ionizer!
NEVER touch the power cord or plug with wet hands
- this may result in electric shock!
220V
Ensure the power plug is firmly and
properly inserted into the outlet
- failure to do so may result in electric
shock or fire!
Do not wash your ionizer by immersion or by pouring
water over the main body;
always unplug your ionizer while cleaning the casing.
Clean with damp sponge or cloth.
Protect your ionizer from freezing
temperatures.
Protect your ionizer from direct
sunlight.
Do not put anything heavy on top of your ionizer.
Do not install your ionizer on an unstable or soft
surface. Install only on a hard and level surface.

Safety Precautions
Common Sense Precautions
Do not attempt to repair or service the unit yourself. Contact your dealer.
Attempting to do so will void your valuable warranty!
Make sure to use your ionizer only with potable water which is suitable for
human consumption.
DO NOT use your ionizer with well water, water with extreme hardness,
high sediment or TDS levels without first consulting 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.
If the appliance makes strange or unusual noises or
burning smells are detected, unplug the power cord
immediately and contact your dealer to arrange service.
Unplug your ionizer if you plan not to use it for an
extended period or turn off the main power switch on
the back of the unit.
Filter replacement may be necessary
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.

Check for leakage by running water through your ionizer
before replacing the housing cover.
Flush out the GAC carbon dust.
- The water will initially come out discolored (light to charcoal
gray) due to carbon particulates 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.

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.
Contamination mixes with
