4. ELECTRICAL CONNECTIONS
WARNING
1. The connections must be made to a separate power supply
or receptacle. Branching off the power cord, using an
extension cord, or sharing a single power supply with other
appliancesmayresultinelectricshock,heatgeneration,re
or malfunction.
2. This product must be earthed. Do not connect the earth wire
to a gas line, water line, lightning rod or telephone earth wire.
Improper earth may cause electric shock.
CAUTION
The maximum allowable voltage variation should not exceed
±10 percent of the rated voltage. Operation of the unit outside
of this range may cause smoking, ignition, damage to the unit
or reduction of the performance.
5. PLUMBING
[a] PLUMBING MATERIALS
*Thewatersupplylineshould be aexible,rigidPVC,or rigid PVC
lined steel pipe in compliance with the applicable water quality
standards.
* Clean the pipes thoroughly before connections to remove shavings,
cutting oils, or other foreign matter that may clog the dual check
valve, pressure reducing valve or water valve.
* Use sealants, sealing tapes, or gaskets to have leak free joints. Do
not use a sealant that can clog pipes or leave odor in water.
[b] WATER SUPPLY LINE
IMPORTANT
1. Use potable water only. Use of non-potable water may cause
corrosion, clogged pipes, or health problems.
2. The water supply pressure must be within 0.1 to 0.75 MPa
(100 to 750 kPa).
3. Depending on water quality, even potable water may cause
scaling inside the water circuit, resulting in failure.
4. Installation of a water treatment device may be required in
some water conditions. Consult a water treatment specialist
or an authorized Hoshizaki service company.
5. Be sure to use the new hose-sets supplied with the
appliance. Do not reuse any old hose-sets.
[c] DRAIN LINE
WARNING
The unit must dispense and drain water into the same sink.
Otherwise, hydrogen gas or chlorine gas may cause health
problems, or the water pipes may corrode, resulting in water
leaks.
IMPORTANT
The drain hoses should be as short and straight as possible.
Always keep the drain hose ends at least 5 cm above the sink
drain outlet.
Connection of the water supply to the HOSHIZAKI water electrolyzer
shall be undertaken in accordance with AS/NZS 3500.1.
Note: Make proper connections to prevent water leaks, resulting in
damage to surrounding property. The plumbing materials must
be prepared on site. Be sure to install a pressure reducing valve
to prevent possible water leaks.
[d] VENT LINE
WARNING
Ensure adequate ventilation. Hydrogen gas or chlorine gas
may cause health problems.
IMPORTANT
1. Ventilate theinstallation site (minimumair ow:450m3/h) to
control chlorine concentration below the maximum level of 0.1
ppm.
2. A ventilation fan, if used, must have at least 15 cm of fan
blade diameter and must be corrosion resistant and installed
close to the unit.
3. Keep gas pipes or corrosive materials away from the air
duct.
4. Do not locate the air duct outlet near a source of ignition.

7. TRIAL RUN
[a] CHECKING WATER HARDNESS
Press and hold the set button on the control panel, and press the
dispense button. The display shows “SEE” and the unit measures the
hardness of tap water.
After 20 seconds, the display indicates the measured hardness, then
goeso󰀨tocompletethemeasurement.
* If the actual water hardness is not measured, the unit regards the
hardness as 200 mg/L (default setting), resulting in a longer cell
ushcycle.
* If the display shows “FAIL”, measure the hardness again after a trial
run.
