10. PREPARING ELECTROLYZER FOR LONG STORAGE
WARNING
When shutting down the electrolyzer for more than a week, turn
off the power switch (earth leakage circuit breaker), and unplug
the unit to prevent electric leak, heat generation, or ignition.
IMPORTANT
Before operating the water electrolyzer next time, check that
the drain valve is closed and open the water supply line shut-off
valve.
1) Follow the “6. SHUT DOWN” and shut down the unit.
2) Close the water supply line shut-off valve.

salt water tank to remove salt completely with tap water.
4) Fill the salt water tank with tap water and connect the salt water
hose.
5) Follow the “4. PURGING SALT WATER PUMP” to wash the salt
water circuit with tap water. Keep the water running for at least 30
seconds.
6) Disconnect the salt water hose from the salt water tank and drain
the hose. Wipe out the salt water hose and salt water filter with a
clean cloth.
