1. CHECKING pH AND AVAILABLE CHLORINE CONCENTRATION

1) Dispense acid and alkaline water into glasses or other containers.
2) Use the Test Paper to check the following values:
Acid Water pH Value
Alkaline Water pH Value
Acid Water Available Chlorine Concentration
Note: It is not necessary to check the available chlorine concentration of alkaline water.
3) Check that each value is within the following range:
Acid Water
Alkaline Water
Note: See the Instruction Manual of each test paper for details of its proper handling. If any of
the checked values exceeds the specified range, contact an authorized Hoshizaki

2. FLUSHING ALKALINE WATER PIPE

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.
IMPORTANT
Be sure to check electrolytic water before use.
