When is adjustment necessary?
When the measurement results are beyond the range of “pH level standardˮ, adjustment shall be
made. After the completion of adjustment, the pH level shall be measured again.
The pH level is relatively high.
The pH level is still high.
The pH level is still high.
The pH level is still high.
Alkaline 3
(pH level is 10 or above.)
Use water of Alkaline 1 or
Alkaline 2.
Please mix with purifi ed water to make
the pH level smaller than 10 before use.
Set [Alkaline pH] of pH
adjustment to [Milder]. (P. EN23)
Decrease the amount of
outlet water.
Weak acidic water
(pH level is more than 6.5.)
Set [Acidic pH] of pH adjustment
to [Stronger]. (P. EN23)
The pH level is
still low.
Set [Alkaline pH] of pH adjustment to
[Stronger].(P. EN23)
The pH level is relatively low.
Weak acidic water
(pH level is less than 5.)
Set [Weak Acidic pH] of pH
adjustment to [Milder]. (P. EN23)
Please mix with purifi ed water to make
the pH level greater than 5 before use.
Alkaline 3
(pH level is less than 9.)
No adjustment
required.
When the pH level of the Alkaline 3 or
weak acidic water is within the range
When the cartridge is relatively new (in about 1 week), the pH level is likely to be slightly high. Please measure the pH level again after about 1 week.

For determination of tap water, color change not shown in the pH Chart may appear due to the influence of the various ingredients in water.
Adjustment method
Preparation: Please turn off the faucet.
The pH level fi ne adjustment changes the pH level in a range from 0.2 to 1.5 for “Stronger” or “Milder” from the “Standard” setting.
(Depending on the water quality and usage conditions, there is some latitude in the amount of the change.)
