1) Dispense acid and alkaline water into glasses or other containers.
2) Use the Test Paper to check the following values:
Check Item Applicable Test Paper
Acid Water pH Value pH Tester TB
Alkaline Water pH Value pH Tester AZY
Acid Water Available Chlorine Concentration Chlorine Tester
Note: It is not necessary to check the available chlorine concentration of alkaline water.
3) Check that each value is within the following range:
Specified range for each value
pH Available Chlorine Concentration
Acid Water Approx. 2.7 or less 20-30mg/L or more
Alkaline Water Approx. 11.3 or more N/A
Note: See the Instruction Manual of each test paper for details of its proper handling. If any of

2. FLUSHING ALKALINE WATER PIPE
IMPORTANT
Scale, such as calcium, magnesium, etc. forms inside the Alkaline Water Pipe.
The use of the alkaline pipe with scale for a long period of time may prevent the
flow of alkaline water, stop the unit or cause poor performance. To prevent scale
from accumulating, flush the Alkaline Water Pipe periodically.
