MEASURING THE HYDROGEN ION CONCENTRATION (pH)  
To ensure that you are drinking ionized alkaline water, please measure the Hydrogen-Ion  
Concentration (pH) on a regular basis.  
1. Extract weak ionized alkaline water, strong ionized alkaline water and  
weak ionized acidic water respectively from the product, fill the high-  
capacity cup with more than 200 ml of the ionized water and then fill  
the exclusive cup with  
15 ml of the ionized  
water.  
200 mL  
15 mL  
2. drop 4 drops of the reagent and lightly swirl the cup.  
3. Compare the color of the ion water with the  
hydrogen Ion Concentration (ph) Color table.  
4. If the hydrogen Ion Concentration (ph) is ph 10 or higher, call the service  
center and request service (213) 386-9900 / (213) 480-1600.  
The hydrogen Ion Concentration (ph) measuring cycle and precautions.  
Immediately after installing this device, measure the Hydrogen Ion Concentration  
(pH) after extracting string ionized alkaline water for at least 4 minutes.  
Tips  
Please check the Hydrogen Ion Concentration (pH) of the ionized water at least once  
a month.

INSTAllATION PRECAUTIONS  
Please check before use!  
The product is for 120 V 60 hz only.  
Please connect the power plug to a dedicated grounded electrical  
outlet for 120 v 60 Hz.  
• When all the lamps on the control panel are turned off  
When all the lamps on the control panel are turned off, check if the power supply has stopped  
due to a power failure or other such reason.  
• If the equipment has not been used for a long time  
If you have not used the product for a long time, extract strong ionized alkaline water for 4  
minutes before using it.  
After extracting strong ionized alkaline water for 2 minutes, the extraction is automatically  
stopped.  
• Regular filter replacement  
It is very important to replace the filter regularly to ensure pure water. If the filter is used beyond  
its service life, the performance of the water purifier deteriorates. Make sure to replace the filter  
regularly.  
• If the product will be not used for a long time  
When the product will not be used for a long time, close the main water supply valve and unplug  
the product.  
After extracting ionized alkaline water for 2 minutes, the extraction is automatically  
stopped.

INSTAllATION PRECAUTIONS  
Check the following before drinking ionized alkaline water  
- Do not drink weak ionized acidic water.  
- Consult a doctor before drinking ionized water from this device.  
- Please do not attempt to modify this product.  
Tips  
Drinking 500 mL ~ 1 000 mL of ionized  
alkaline water is recommended. When  
drinking ionized water for the first time,  
dilute a small amount of ionized water  
with filtrated water. If you drink a large  
amount of ionized alkaline water from  
the beginning, you may experience  
ahealing crisisdepending on your  
physical constitution.  
Do not take medicine with ionized  
alkaline water. Take medicine with  
filtrated water and not ionized water.  
Do not drink ionized  
water with medicine!  
Go from weak to  
strong ionized  
alkaline water slowly!  
Persons corresponding to any of the  
following cases, must consult a doctor  
before drinking ionized water.  
1. Persons drinking ionized alkaline  
water for the first time.  
2. Persons with a chronic disease.  
3. Persons with liver, intestinal or kidney  
trouble.

appear during the healing  
process. Although a healing  
crisis may appear as an eruption,  
diarrhoea, tiredness etc. when  
drinking ionized alkaline water,  
it is temporary and just part of  
the healing process. Therefore, in  
this case, drink a small amount of  
water over a long time.

drinking weak alkaline water (pH 8.9  
or higher) with rich minerals is Ok.

the water into an airtight glass container  
and keep it in cold storage. Drink any  
stored ionized alkaline water within 3 days.

[Achlorhydria] This is a symptom  
where a person has difficulty  
in digesting food due to  
insufficient bile acid or gastric

Tips  
After installing the product, measure the  
Hydrogen Ion Concentration (pH) more  
than once a month and confirm that it  
is lower than pH 10, before drinking the  
water.  
Persons with kidney trouble such as a  
renal insufficiency or potassium excretion  
failure must not drink alkaline water.

If you feel any abnormality in your body  
or if your stomach and intestines do not  
get better after drinking continuously,  
stop drinking the water and consult a  
doctor.  
Drink ionized alkaline water immediately  
after extraction.

ClEANING METHOD  
Cleaning function  
1. Initial cleansing  
When you connect the power cord and turn on, the initial cleansing is performed for about 3 minutes  
through the weak acidic dedicated faucet and the alkaline ionized water extraction pipe.  
If you want to stop the initial cleansing, please press any button.  
If you connect the power cord without turning off,  
please reconnect the power cord with turning off .  
When the product is cleansed, the alkaline ionized  
water extraction pipe must be placed toward  
the sink ball.  
2. Waiting cleansing after extracting  
If 15 seconds waiting time is passed after extracting the alkaline ionized water/the weak acidic  
ionized water, the electrolyzer and filter is cleaned automatically for 16 seconds.  
The waiting time 15 seconds are passed after extracting the alkaline ionized water/the weak  
acidic ionized water.  
In case that the weak acidic water is extracted, when the alkaline ionized water or the filtered  
water button are turned on within 15 seconds, the electrolyzer is cleaned automatically for 5  
seconds.  
For about  
16 seconds  
3. Stop time cleansing  
If you don’t use the product for 24 hours, electrolyzer and filter are cleaned automatically for 15

ClEANING METHOD  
Check the following when you cannot extract water  
Check if the Cleaning lEd is turned on.  
This product has a built-in self-cleansing function to protect  
internal parts.  
Since ionized water is not extracted when the Cleaning LED is  
turned on to ensure your safety, please use it after the Cleaning  
LED is turned off.  
The Cleaning lED is turned on in the following cases  
1. The Cleaning lEd is turned on for 16 seconds when no operation is  
performed for 15 seconds just after extracting ionized water.  
2. The Cleaning lEd is turned on for 15 seconds when no operation is  
performed for 24 hours after extracting ionized water.  
3. The Cleaning lEd is turned on for 5 seconds to prevent the drinking  
of acidic water, when extracting ionized alkaline water or filtered  
water just after extracting ionized acidic water.  
Please use after the Cleaning LED is turned off.  
While cleansing  
While cleansing, drain water flows out through  
the weak ionized acidic water faucet.  
Since the water that flows out at this time is water  
where the hydrogen Ion Concentration (ph) is not  
controlled, do not drink it.

FIlTER REPlACEMENT  
Filter  
The life of the product is determined by the filter. If the filter is not a  
genuine filter or the genuine filter is used too long, the filter performance  
can be lowered and the water may not be filtrated properly.  
Please replace the filter with a genuine filter following the replacement  
cycle.  
A coordinator from Woongjin Coway Ltd, Co.’s will visit you directly and  
replace the filter.  
To replace the filter, please call (213) 386-9900 / (213) 480-1600.  
Filter replacement cycle  
If the filter is not regularly replaced, it may degrade the water quality of the  
product.  
The filter change cycle may vary within the range of the expected  
replacement cycle depending on the water feed quality.  
The filter replacement cycle is determined on an average 10 ℓ (4 person  
family) per day for home use.

Water leaks.  
To prevent water overflowing by  
mistake, ionized water extraction is  
automatically stopped when a preset  
time has passed.

: Stops after 2 minutes of continuous  
extraction  
The operation  
automatically  
stops when  
extracting ionized  
water.  
Has the extraction time exceeded the preset  
time?  
- Weak acidic ionized water: Stops after  
2 minutes of continuous extraction.  
This is caused by the calcium mineral  
that melts in the water has been  
extracted, depending on the main  
water quality.  
Although drinking the water is safe, if  
this symptom continues, ask for after-  
sales service to protect the product.

Has the calcium ion in the water combined with  
the carbonic acid in the water?  
Noise is  
generated inside

when extracting  
ionized water.  
The noise is generated when ionized  
water is generated by the electrolyzer  
and this is normal.

flowing when extracting ionized water?
