IMPORTANT SAFETY INFORMATION
Throughout this manual, notices appear to bring your attention to situations which could result in death, serious injury, or damage
to the unit.

WARNING

Indicates a hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION

Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.

NOTICE

Indicates a hazardous situation which, if not avoided, could result in damage to the unit.

HYGIENE

Indicates important precautions for hygiene and food safety.

IMPORTANT Indicates important information about the use and care of the unit.
IMPORTANTThis booklet is an integral and essential part of the product and should be kept and preserved by the user.
Please read carefully the guidelines and warnings contained herein as they are intended to provide the user with essential
information for the continued safe use and maintenance of the product. In addition, it provides GUIDANCE ONLY to the user
on the correct services and site location of the electrolyzer.
Please preserve this booklet for any further consultation that may be necessary.

WARNING
This is a water electrolyzer, and should be destined only to be used for the purpose for which it has been expressly designed.
Any other use should be considered improper and therefore dangerous. The manufacturer will not be held liable or responsible
for any damage caused by improper, incorrect and unreasonable use.
The installation, and relocation if necessary, must be carried out by qualified personnel, in accordance with current
regulations, according to the manufacturer’s instructions.
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 qualified persons inorder 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 applianceby a person responsible for their safety.
* Children should be supervised to ensure that they do not play with the appliance.
* Do not attempt to modify the electrolyzer. Only qualified personnel may disassemble or repair the appliance.

CAUTION
Do not use a flame near a container or tank holding electrolyzed water. Hydrogen gas from cleaning water may cause ignition.

[c] CHECKING AND ADJUSTING CURRENT[a] WHEN FLUSH LAMP FLASHES

The current of sanitizing water can be checked and adjusted. The pH
and available chlorine concentration are adjustable by changing theelectrolytic current.

The flush lamp on the operation panel may flash while the unit isdispensing water. This means sanitizing water has been dispensed
for 60 minutes in total and the unit is ready to start an automatic flush
cycle for the water circuit and electrolytic cell. If the dispensing action
is stopped right away or continued for 5 minutes after the flush lamp
starts flashing, the unit begins an automatic flush cycle.

* The electrolytic current is factory adjusted to 13A.
* Adjust the electrolytic current only when the raw water quality
causes the pH or available chlorine concentration go outside thespecified range.

44) Press the set button. The display shows “0.00” (0:00).

9. MAINTENANCE[d] WATER LEAKS (DAILY)[a] EXTERIOR (AS REQUIRED)

Check the unit and surrounding floor for water leaks. If any is found,contact an authorized Hoshizaki service company.

The exterior is easily contaminated. Keep it clean.

[e] EARTH LEAKAGE CIRCUIT BREAKER (MONTHLY)

Note: The exterior surface is painted. Do not use a commercial
stainless steel cleaner.

WARNING
Check the earth leakage circuit breaker for proper operation
once a month. If it is left inoperable, it could increase the risk ofelectric shock in case of electric leak.

To prevent deformation or cracking, do not spray insecticide on
the plastic parts or allow them to contact oily materials.
1) Wipe the exterior with a cloth containing warm water and a neutral
cleaner.

11. PURGING SALT WATER PUMP

If water is not dispensed from its proper outlet, contact anauthorized Hoshizaki service company.

This unit uses a pump to supply salt water. If the salt water pumpcontains air, electrolyzed water cannot be dispensed properly. Whenthe add salt water lamp on the operation panel comes on and salt
water tank is refilled, purge air from the salt water pump as follows:[b] SALT WATER LEVEL (DAILY)
Check the salt water level in the salt water tank (accessory) according
to “3. [a] CHECKING AND SUPPLYING SALT WATER”.

1) Check that the salt water tank (accessory) is filled with salt water.
2) Check that the power switch (earth leakage circuit breaker) is on. If
not, turn it on.

[c] CELL RUN TIME, CURRENT, VOLTAGE (DAILY)

3) Press and hold the reset button on the control panel until the add
salt water lamp flashes. After 90 seconds, the salt water pumpstarts running and pumping up salt water to purge the salt water
hose.

Check the present time, cell run time, current, and voltage. Pressthe display select button on the control panel until the desired item
appears in the display.

64) When the salt water pump has been purged, the pump stops, water
stops coming out of the nozzle, and the add salt water lamp goesoff.

3) If the display shows “E22” again after operation is resumed, contact
an authorized Hoshizaki service company.
