III. OPERATING INSTRUCTIONS

1. FUNCTIONS AND ADJUSTMENT OF SET ITEMS

The water electrolyzer is provided with the nine set items of the following functions:

No.

Set Items

 

 

Functions

 

 

 

A1

Cell Lifecycle (h)

Adjustment is required if the electrode lifecycle gets longer

 

 

3000 - 8000

(Initial: 3000 h).

 

 

 

A2

Amperage (A)

Changes the pH value (Initial: 14.0 A).

 

 

0.0 - 18.0

To increase the pH value, raise the amperage.

 

 

 

A3

Voltage (V)

Changes the available chlorine concentration (Initial: 10.0 V).

 

 

0.0 - 18.0

To reduce the residual chlorine concentration, raise the voltage.

 

 

 

A4

Cell Reverse Time (h)

Adjustment is required if the electrode lifecycle gets longer

 

 

0 - 150

(Initial: 12 h, 0 means no reversal).

 

 

 

A5

Amperage

Changes the reaction to the varying amount of additional

 

 

Accumulation Time (s)

concentrated salt water (Initial: 3 s). To delay the amperage

 

 

1 - 90

feedback reaction, extend the time setting.

 

 

 

A6

Storage Mode/

Chooses between hand-washing mode using the optional

 

 

Hand-washing Mode

remote controller and storage mode to store water in the tank

 

 

 

(Initial: hand-washing mode).

 

 

 

A7

Cell Running/

Resets the built-in timer for replacing the Electrolytic Cell.

 

 

Reverse Time Reset

 

 

 

 

 

 

 

A8

Initial Flush Cycle (s)

Changes the time to supply water for flushing away non-

 

 

0 - 120

electrolyzed water in the Electrolytic Cell in the initial operation

 

 

 

(Initial: 3 s).

 

 

 

A9

Automatic Dispensing

Adjusts the dispensing time for automatic dispensing control

 

 

Control 10 s - 4 m

(Initial: continuous).

 

 

 

Continuous: Continuously dispenses until the Dispensing

 

 

 

 

Button is pushed for the second time.

 

 

 

Automatic: Automatically stops when the adjusted time has

 

 

 

 

passed since the Dispensing Button is pushed.

 

 

 

 

 

 

 

 

 

 

 

IMPORTANT

 

 

 

 

 

 

 

1.The set items A1, A4, A5, A8 and A9 should not be changed unless directed by an engineer.

2.The set item A7 should be used only when the Electrolytic Cell is replaced.

Note: 1. The set amperage and voltage can be changed just by turning each control volume. For more accurate adjustment, however, always use the A2 and A3 adjust modes
