This electrolyzer is not intended for outdoor use (including under canopy). Exposure to rain may cause electric leak or shock.
Direct sunlight can damage the plastic tank exterior, resulting in cracks and water leaks.
Ensure adequate ventilation. Hydrogen gas or chlorine gas may cause health problems.
Do not mix electrolyzed water with other chemicals. Mixture with acidic or chlorine-based chemicals can cause chlorine gas,
resulting in health problems.
Do not use a large volume of sanitizing water only. Generation of a large amount of chlorine gas may cause health problems
or corrosion of surrounding equipment.
The use of any electrical appliance involves the observance of some fundamental rules. In particular:
* Instances of high humidity and moisture increase the risk of electrical short circuits and potential electrical shocks. If in
doubt, disconnect the electrolyzer.
* Do not damage the power cord or pull it in order to disconnect the electrolyzer from the electrical supply network.
* If the supply cord is damaged, it must be replaced by your local Hoshizaki service agent or similarly qualied persons in
order to avoid a hazard.
* Do not touch the electrical parts or operate the switches with damp hands.
* This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities,
or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance

Reactions at Anode
Chloride ions (Cl-) and hydroxide ions
emit electrons (e-) to the anode, which
become hypochlorous acid (HOCl).
Reactions at Cathode
Sodium ions (Na+) receive electrons (e-)
from the cathode and become sodium
metal (Na) which reacts with water (H2O)
and becomes sodium hydroxide (NaOH)
and hydrogen gas (H2).

Reactions at Anode
Chloride ions (Cl-) and hydroxide ions emit electrons (e-) to the anode,
which become hypochlorous acid (HOCl).
Reactions at Cathode
Sodium ions (Na+) receive electrons (e-) from the cathode and
become sodium metal (Na) which reacts with water (H2O) and
becomes sodium hydroxide (NaOH) and hydrogen gas (H2).
Salt water contains four kinds of ions; sodium ions (Na+), chlorine
ions (Cl-), hydrogen ions
(H+) and hydroxide ions (OH-).
NaCl + H2O → Na++ Cl-+ H++ OH-
(Mix water and salt) Salt water (4 kinds of ions)
When two electrodes are inserted into salt water and voltage is
applied:
Negative ions (Cl-) are drawn to the anode, and
Positive ions (Na+) are drawn to the cathode.
At the anode, hydrogen chloride (HCl) and hypochlorous acid (HOCl)
are generated.
2Cl-+ H2O → HCl + HOCl + 2e-
Electrons (2e-) are emitted to the anode, which means the acidic
water (HCl + HOCl) causes
oxidization. [As electrons are emitted, the oxidization/reduction
potential becomes positive (+mV).]
Chlorine ions also emit electrons and become chlorine gas (Cl2).
2Cl- → Cl2+ 2e-
(Cl2= chlorine gas)
At the cathode, sodium hydroxide (NaOH) and hydrogen gas (H2) are
generated.
Na++ H2O + H++ 2e- → NaOH + H2
Electrons (2e-) are received from the cathode, which means the
alkali water (NaOH) causes reduction. [As electrons are received, the
oxidization/reduction potential becomes negative (-mV).]
