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.
Please check the Hydrogen Ion Concentration (pH) of the ionized water at least once
a month.
Tips
MEASURING THE HYDROGEN ION CONCENTRATION (pH)
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 .
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 .
To ensure that you are drinking ionized alkaline water, please measure the Hydrogen-Ion
Concentration (pH) on a regular basis.
