You have just purchased the finest, most advanced water system in the world!
Your new ionizer is designed to provide you with many years of the cleanest,
healthiest and most “functional” water available. There are many specific uses
and benefits of this amazing water, so read this manual carefully to learn how
to get both optimum performance out of your ionizer and to protect your investment.
Your new ionizer produces filtered alkaline, ionized water. Just exactly what is that?
Your ionizer employs computer accurate and selectable magnetic energy to perform
electrolysis through patented platinum bonded titanium electrodes inside a water cell.
Inside this advanced cell, the magnetic energy separates the water into an alkaline
(high pH) and acid (low pH) stream without using any chemicals. Ionizing the water
in this way re-structures the molecules and reduces their cluster size, binds extra
oxygen molecules, and concentrates ionized, absorbable and beneficial minerals like
Calcium, Magnesium and Potassium.

WARNING
The following symbols are used for different levels of warning.
DANGER
DANGER
CAUTION
: Could cause personal injury or have an adverse effect on health.
: Could cause damage to ionizer and possibly void your warranty.
: Please read these pages carefully. They contain very important information
to protect you and the valuable warranty on your ionizer.
If you have a chronic disease or serious health issue then please consult with a
healthcare provider before using the ionizer.
Do not drink alkaline water if you have achlorhydria.
Consult a healthcare provider before using acidic water if you have:
- Sensitive skin
- Allergies
Only use potable drinking water in your ionizer.
If on hard water please ask about pre-treatment options
Well water and water from smaller systems should be tested for safety before
using with an ionizer, and may require pre-filtering.
If you have never consumed alkaline water – start off with the lowest alkaline setting (level 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.
Customers in hard water areas may need additional treatment otherwise risk voiding their valuable
warranty. If unsure about the quality of your water please contact a water specialist.
Precautions : Do not use the following types of water.
Contaminated Salt water or Softened water
Turbid water Hot water over 104 Fahrenheit / 40 Celsius
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!
Protect your ionizer from
freezing temperatures or from
direct sunlight.
When using the unit in a cold
place, remove the filter after
use to prevent the filter from
freezing.
The acidic water hose should
be installed so that the end is
lower than the connection at
the elbow on the ionizer. The
water should flow freely down
from the elbow.
Be sure that the ionizer is
connected to a COLD water
source. Connecting it to a hot
water source could damage
the water cell or other parts
of the ionizer.
Keep the power cord and your
ionizer away from hot surfaces
or appliances - failure to do
so may result in electric shock
or fire!
Do not try to fix the ionizer
yourself. Call the dealer to
have it fixed by a qualified
technician.
Don't move the unit by the
front cover. The unit could be
damaged or cause you bodily
injury if the cover falls off and
the main body falls.
Move the unit by putting both
hands underneath it. This will
prevent the unit from falling
during movement.
Don't use the unit in a dusty
place. This may cause the unit
to malfunction.
If the power cord develops a
break or short, stop using the
unit and call customer service
to have it replaced.

Disconnect the cold water
hose from the line. Make
sure it is the cold water hose
and not hot because hot
water will cause the unit to
malfunction.
Connect the cold water line
adapter to the cold water
supply valve as shown.
As fittings vary you will need
to find the right size adaptors
at your local plumbing store.
Connect the plastic tubing
as shown.
6Connect hoses to the water
inlet and acidic water outlet
then open the cold water
supply valve.
Separate the water line.
CAUTION
Be sure the valves are all connected tightly to prevent leakage.
Be sure of where you want to install the ionizer as a hole needs to be drilled through the sink
top to thread the tube.
Be sure you connect the unit to cold water as hot water can damage the unit.
This is a good time to double check and make sure all your fittings are tight and the tubing is
secure in the fittings.
Check daily for any leaks during the first week after installation and check for leaks occasionally
thereafter.
CAUTION
When switching from Acidic water to Alkaline water, let the water run for 5 seconds before drinking.
Run acidic water through the unit for 10 to 15 seconds each day before drinking the water.
Run acidic water through the unit for about 30 seconds if the unit has not been used for several days.
Set the water supply valve to the “ON” position.
This is the knob on the front of machine and has an
“ON” and “OFF” position. Important; This is one of
the most critical features in controlling your ionizer’s
performance. This contro WILL DIRECTLY impact
the performance of your ionizer.
A slow flow will yield higher pH; a fast flow will yield
lower pH.

The filter life indicator consists of 5 sections of light for each filter. When the filter is ready to
change, all the sections of light will go off. An audio message will give a warning 10 days in
advance of filter replacement. When the filter indicator blinks, the filter must be replaced.
There are instances in which sediment and carbon filters should be changed separately
depending on the places of use or region.
Filter life will change depending on the region's water quality. If water flavor worsens or if the flow
rate slows down considerably, it is highly recommended to change the filter.

Trouble shooting Calcium in water
Possible cause ResolutionSymptom ExplanationCalcium in water
Please check out the following troubleshooting suggestions before calling for repair.
Display panel does not
light up.
* Is the power cord plugged in
correctly to an active outlet? * Plug the power cord in properly.
Switch does not work. * Is the power plug connected to the
outlet properly?
* Is the fuse on the back blown?
* Plug the power cord in properly.
* Check the fuse and replace it if neces-
sary.
Water does not flow out
or the unit has stopped
functioning.
* Is the source water valve line closed?
* Is the source water line connected?
* Is the hose bent?
* Is the water pressure too low?
* Is the main water supply turned on
or is the line frozen?
* Is the filter clogged?
* Running the acidic water on
Acidic Level 3 for 10+ mins.
* Turn the water supply valve on.
* Be sure the water supply hose is
connected properly.
* Be sure the water line is not bent.
* Replace the filter.
* If the unit is leaking, turn off the water
supply valve and contact customer
service.
* Replace the filter.
* Turn off the ionizer at the power switch
for 5-10 minutes to allow for a reset
period then turn the ionizer back on.
Water is leaking from the
hose at the attachment.
* Check to see if the hose is
disconnected
* Connect the hose snugly to the
attachment.
The water has a strange
odor or tastes bad.
* Has the unit been unused for a
long time?
* Has the drain water hose been
immersed in water?
* Let acidic water flow through the unit
for 3minutes or more. If the water
does not improve, replace the filter.
* Remove the drain hose from water.
Even though the filter has
been replaced, the filter life
indicator still shows no-life.
* Did you reset the filter counter? * Reset the filter by pressing the filter
replacement button.
There is a strange noise
coming from the unit.
* Unknown. * Switch off and stop using the ionizer
and contact customer service.
When filling your cup with alkaline water, white
flakes are seen floating in the cup.
* When ionized water is generated, the water
molecules are reduced in size. This results in a
higher concentration of dissolved hydrogen in
the water.
* This large quantity of mineral flakes in the water
may occur right after a filter change or first use
of the ionizer. There is no problem with drinking
this water as it is mostly calcium which is not
harmful to consume.
When high alkaline water is left in a container,
the water will form a white film around the
edges or on the bottom. The substance is
CaCO2 which has bonded with calcium and
falls to the bottom of the container.
If you prefer to not have this white substance
in your water, adjust the pH to a lower level
which will reduce the possibility of calcium
bonding.
Calcium flakes form by bonding with hydrogen
which is abundant in alkaline water.
The presence of calcium is a sign that the water
ionizer is functioning properly. If you would like
to clean calcium out of any container, put a
spoonful of vinegar in the container and fill it
with water. Vinegar will dissolve the calcium.
Leave the water in the container for 1 hour and
shake the water out.
