1) Prepare a plastic bucket. 

Pull out the cap, salt water 

hose and filter from the salt 

water tank, and put them 

into the bucket.

2) Use the measuring cup (accessory) 

to add one level cup (approx. 

700ml) of sodium chloride (NaCl) or 

potassium chloride (KCl) into the salt 

water tank.

3) Add water into the salt water tank up 

to the 5 L line.

4) Check that the mini cap is closed, and put 

the cap on the salt water tank. Shake it 

until sodium chloride or potassium chloride 

completely dissolves in the water.

5) Open the mini cap and put it in the recess, 

and push in the salt water hose until the 

stopper hits the cap.

4. PURGING SALT WATER PUMP

This unit uses a pump to supply salt water. If the salt water pump 

contains air, electrolyzed water cannot be dispensed properly. When 

the unit is installed for the first time or when the add salt water lamp 

on the operation panel comes on, purge air from the salt water pump 

as follows:

1) Check that there is enough salt water in the salt water tank.

2) Check that the power switch (earth leakage circuit breaker) is off. 

Turn it off if it is on.

3) Turn the power switch back on.

4) Press the dispense button on the operation panel.

5) Check that the add salt water lamp is on.

6) Press the reset button.

7) The pump starts running and pumping up the salt water to purge 

the salt water hose. About 90 seconds later, the pump stops.

8) The unit drains water to flush out the electrode before shutting 

down. The add salt water lamp goes off.

* Do not press the dispense button on the 

operation panel, the power switch or any 

other switches before the add salt water 

lamp goes off. Otherwise, the lamp cannot 

be reset, and the above procedure must be 

repeated from step 5). Wait until the unit 

flushes  out  the  system  and  completes  the 

resetting procedure.

* Always locate the salt water tank below the 

end of the water outlets, or the salt water 

tank will leak salt water by siphonage and 

the unit may fail to operate properly.

5. START UP

1) Plug in the unit.

2) Open the water supply line shut-off valve.

3) Check for proper operation of the water softener. Refer to the 

instruction manual provided for operating instructions. See “9. 

[f] WATER HARDNESS (WEEKLY)” for how to check for water 

softening.

4) Check that the salt water tank is properly set up.

5) Turn on the power switch (earth leakage circuit breaker). A 

mechanical sound is heard three times immediately after the power 

switch is turned on. This is not a sign of failure.

6) Press the dispense button on the operation panel.

7) The operation lamp comes on.

8) The ready lamp starts flashing, and non-electrolyzed water is 

dispensed at first.

9) When the unit starts to dispense electrolyzed water of the intended 

quality, the ready lamp stays on continuously.

10) Check that the add salt water lamp is off. If it is on, follow “4. 

PURGING SALT WATER PUMP” to supply salt water to the 

electrolytic cell until the lamp goes off.

11) To stop dispensing water, press the dispense button on the 

operation panel again. The ready lamp goes off. The unit goes 

through the flush cycle before water stops.

* While  the  ready  lamp  is  flashing,  the  quality  of  electrolyzed  water 

has not reached the intended level. If the available chlorine 

concentration and pH value are less than the specified values, 

sanitizing water may not provide a sufficient bactericidal effect.

* Before using electrolyzed water, check that the ready lamp stays on.

6. SHUT DOWN

1) For daily shutdown, press the dispense button on the operation 

panel. The  ready  lamp  flashes  for  about  3  seconds  and  the  unit 

stops dispensing electrolyzed water. To restart the unit, press the 

dispense button on the operation panel.

2) For long storage, see “10. PREPARING ELECTROLYZER FOR 

LONG STORAGE”.

7. WATER FAILURE

In case of water failure, follow the instructions below:

1) Shut down the unit according to “6. SHUT DOWN”.

2) Wait until water supply is resumed.

3) Check that the water supply valve is closed.

4) Open the drain valve.

5) Open the water supply line shut-off valve. Drain water until no rusty 

water comes out.

6) Close the drain valve.

7) Start up the unit according to “5. START UP”.
