1. FEATURES

[a] FLOOR MOUNTING OR FIXED MOUNTING

The floor mounting and fixed mounting options are available. Use the rotary Select Switch

provided on top of the Operation Panel to choose between the two options. If the fixed mounting

option is selected, the Bin Control Switch in the Control Box will become functional.

[b] BIN CONTROL ADJUSTMENT (Fixed Mounting Only)

The sensitivity of the Bin Control Switch in the Control Box is factory-adjusted for the standard

Storage Bin B-500. If requested by the customer, it is adjustable by turning the Adjust Screw on

the Bin Control Switch. See "4. BIN CONTROL ADJUSTMENT" in the installation manual for

further details.

[c] ICE PRODUCTION CONTROL (Fan Control)

The ice production will increase at low ambient or water temperature. As a result, the Gear

Motor will have a higher torque to harvest ice, and the icemaking mechanism will be overloaded.

To prevent this condition, the icemaker controls the Fan Motor rotation speed to keep the

discharge pressure in the refrigeration circuit within a proper range.

[d] OVERLOAD PROTECTION

Despite the above-mentioned ice production control, some use conditions (water quality etc.)

or variable part tolerances may overload the icemaking mechanism. A photomicrosensor will

detect overload by reduction in Drum rotation speed and shut down the icemaker. This can

avoid a costly breakdown of the icemaking mechanism or the like.

[e] USER RESET

When a protector trips to shut down the icemaker, an error code will be displayed. If it is a

resettable error, the user can restart the icemaker by pressing the Reset Button accessible from

the Window Panel and continue the icemaking operation until a service person arrives. Some

errors are non-resettable or repetitive and require troubleshooting by qualified personnel.

[f] ERROR CODES AND RECORDS

When the icemaker shuts down with an error, the Display Window will show an error code "E_".

A maximum of eight most recent records are memorized and can be checked at the time of

service or inspection.

[g] OTHER INFORMATION

Other information is also available from the Controller Board. See "III. 7. OPERATION BOARD"

for details.

[h] CHANGE OF ICE TYPE

The ice type is changeable by replacing the Pulleys provided on the Gear Motor and Gear Head

driving the Evaporator (Drum). The icemaker is factory-adjusted in the "Thick Ice" mode, but

can be changed to the "Thin Ice" mode by replacing the Pulleys.

II. MAINTENANCE AND CLEANING INSTRUCTIONS

IMPORTANT

This icemaker must be maintained individually, referring to the instruction manual

and labels provided with the icemaker.

1. TIMING BELT

The Timing Belt transmits power from the Gear Motor to the Gear Head. It may wear or deteriorate

and break after a total of 15,000 hours of Gear Motor operation.

2. CONDENSER

Check the Condenser once a year, and clean if required by using a brush or vacuum cleaner.

More frequent cleaning may be required depending on the location of the icemaker.

3. AIR FILTER

A plastic mesh Air Filter removes dirt or dust from the air, and keeps the Condenser from getting

clogged. As the Filter gets clogged, the icemaker’s performance will be reduced. Remove and

clean the Air Filter at least twice per month:

1) Push down the Lock and take off the Louver.

Note: Do not put your hand inside the machine compartment.

2) Remove the Air Filter by pushing it down.

3) Clean the Air Filter by using a vacuum cleaner. When severely

clogged, use warm water and a neutral cleaner to wash the Air

Filter.

4) Rinse and dry the Air Filter thoroughly, and place it in position.

4. GREASE UP (BEARING)

The Bearing supporting the Drum rotation requires periodic greasing. Use Dow Corning G-

4500 to grease up the Bearing once a year. See step 32) in "V. 7. EVAPORATOR ASSEMBLY"

for the replacement procedure.

5. PERIODICAL CLEANING

1) Machine and Bin Exterior

Wipe the exterior at least once per week with a clean, soft cloth. Use a damp cloth containing a

neutral cleaner to wipe off grease or dirt.

2) Storage Bin Interior Cleaning/Sanitisation (as required) [fixed mounting only]

1) Open the Storage Bin Door, and remove all ice.

2) Wash the Bin Liner, Ice Deflector and Door inner surface with a neutral non-abrasive cleaner.

Rinse thoroughly with a clean cloth and fresh water.

3) Mix 5 litres of water with 18 mL of 5.25% sodium hypochlorite solution in a suitable container

or the recommended Hoshizaki sanitiser as directed.

4) Soak a clean sponge or cloth with the solution and wipe all the surfaces of the Bin Liner, Ice

Deflector and Door inner surface.

5) Rinse thoroughly with fresh water and a clean cloth to wipe off the solution. Close the Bin

Door.

Note: Some solutions may cause damage to the Bin liner surfaces or corrosion on the metal

parts. Always rinse the sanitiser unless directed otherwise by Hoshizaki guidelines.

3. ICEMAKING MECHANISM

[a] EVAPORATOR (DRUM)

The Evaporator consists of an aluminum alloy cylinder with an icemaking surface on its exterior,

a press-fit plastic part with a refrigerant path, and a shaft for refrigerant supply and rotation. The

Evaporator penetrates the side of the Tank, and the Cutter scrapes off ice forming on the

Evaporator surface.

[b] CUTTER

The stainless steel Cutter is fixed on the Tank so that it can be repositioned against the Evaporator.

[c] BEARING

The Bearing is installed on one side of the Tank to support the Evaporator (Drum) Shaft. The

Gear Head provides the same function on the other side of the Tank where the Gear Motor is

located to drive the Drum.

[d] MECHANICAL SEAL

The Mechanical Seal prevents refrigerant leaks from the rotating Drum. The rotary ring attached

to the Shaft and the stationary ring fixed on the Housing form a carbon ring shaft sealing system.

[e] HEATER (CUTTER)

The Heater provided on the backside of the Cutter prevents ice jamming on the Cutter resulting

in a clogged Spout and ice forming on the back of the Cutter at a low temperature. The thermal

sensor attached on the water inlet controls to energize the Heater.

[f] HEATER (TANK)

The Heater provided inside the Tank prevents the Float Switch from freezing. As with the Heater

for the Cutter, the thermal sensor attached on the water inlet controls to energize the Heater.

[g] GEAR MOTOR

The Gear Motor consists of a 1 phase 230V drive motor integrated with a decelerator and

provided with a built-in auto-reset Thermal Protector. When the Thermal Protector trips, the

Controller Board will stop the Gear Motor. The Protector can be reset by the Reset Button on

the Operation Board. The Thermal Protector trips when the Gear Motor mechanism is overloaded

or when excessively high or low voltage is applied on the Gear Motor. The electrical capacity

must be increased if a large current flows through the surrounding equipment.

4. WATER CIRCUIT

[a] FLOAT SWITCH

The Tank holding the Evaporator is provided with a plastic Float Switch to detect the water level.

The floats move up and down along with the water level and send ON/OFF signals to open/close

the Water Valve in order to maintain the proper water level.

If the proper water level cannot be resumed within about 20 minutes after the Float Switch sends

an OFF signal, the icemaker will detect a low water condition and shut down. The icemaker will

automatically restart icemaking operation when the proper water level is resumed within 80

minutes.

If the Float Switch trips at the upper float level for 10 minutes after the Tank fills up, the icemaker

will display “E1” for no ice production error and shut down.

If the Float Switch trips at both upper (fill) and lower (empty) float levels, the icemaker will display

“E2” for a switch contact error and shut down.

See “9. ERROR CODES” for details.

[b] CONTROL WATER VALVE

The Control Water Valve located above the Tank will open to supply water to the Tank when the

coil is energized. Despite the water pressure varying from 0.3 bar to 8 bar at the water supply

inlet, the built-in flow controller maintains almost the same water flow (100V AC).

[c] FLUSH WATER VALVE

The Flush Water Valve is energized to open and flush out the Tank (100V AC) after the icemaker

shuts down and every 12 hours when the Storage Bin is used.

[d] DRAINING ICEMAKER IN SUBFREEZING CONDITIONS

In winter, the water circuit must be completely drained out or otherwise protected to prevent

freeze-up and damage before shutting down the icemaker at night.

1) Close the Water Supply Line Shut-off Valve to stop water supply.

2) Open the Air Shut-off Valve.

3) Press the Stop Button, and drain the Float Tank and Evaporator.

4) Turn off the icemaker.

Before restarting the icemaker:

1. Close the Air Shut-off Valve.

2. Open the Water Supply Line Shut-off Valve.

[b] SERVICE INSTRUCTIONS

Always restore the original bindings after servicing the refrigeration circuit. Otherwise, vibration

may cause overstress and damage to the circuit, resulting in refrigerant leak.

After replacing the Evaporator (Drum), Mechanical Seal, Bearing, or Oil Seal, run the icemaker

for 30 minutes to produce ice, check for impurities, and discard.

[c] REFRIGERANT CONTROL (Compressor Cooling)

See “1. WATER AND REFRIGERANT CIRCUIT”.

Fan Cooling

The Fan Motor blows air over the Compressor to release its heat.

[d] REFRIGERANT CONTROL (Ice Production Control)

Fan Speed Control

Increased ice production in a low temperature condition will overload and damage the icemaking

mechanism. To control the ice production, the Controller Board energizes and de-energizes

the Fan Motor to reduce its rotation speed.

[e] REFRIGERANT

The icemaker employs refrigerant R404A which itself is not flammable or poisonous. However,

a small room filled with R404A may cause suffocation with a lack of oxygen. Also, when exposed

to an open flame, R404A creates Phosgene gas, hazardous in large amounts. Handle the

refrigerant in a well-ventilated area with no flames.

Always recover the refrigerant and store it in a proper container, if required by an applicable

law. Do not discharge the refrigerant into the atmosphere.

[f] COMPRESSOR

The Compressor absorbs the low-pressure refrigerant gas vaporized in the Evaporator (to reduce

the pressure inside the Evaporator), compresses the refrigerant into high-temperature high-

pressure gas, and sends it out to the Condenser.

The hermetic-type Compressor is efficient in refrigeration, and the refrigeration circuit is designed

to endure long hours of operation. The Compressor is mounted on vibration damping rubber to

prevent transmission of vibration. In case of accidental overload, the Case Thermostat or

Overload Relay will shut down the Compressor. The Reset Button must be pressed to reset the

Overload Relay.

[g] EVAPORATOR (DRUM)

The Evaporator is a drum with shafts at both ends and a refrigerant path between a metallic

exterior and a plastic interior. The refrigerant flows through a very narrow path in the Expansion

Valve with a sudden drop of pressure and evaporates by absorbing heat of vaporization from

the Evaporator. The water supplied inside the Tank holding the Evaporator is deprived of heat

and forms thin ice around the Evaporator, which will be scraped off by the Cutter.

[h] CONDENSER

The Condenser refrigerates and liquefies the high-temperature high-pressure refrigerant gas

discharged from the Compressor into high-pressure liquid refrigerant.

A dirty Condenser will significantly reduce the refrigeration efficiency and performance, and will

also shorten the service life of the components (especially refrigeration circuit). The Condenser

must be cleaned according to the following instructions. The frequency of cleaning depends on

the installation conditions.

Air-cooled Condenser (Fin-and-tube type)

A copper tube is attached on a finned aluminum plate with high heat conductivity to promote

heat radiation, and a Fan Motor is also provided for forced air cooling. A remote type Condenser

is also available to protect the interior from noise of the Fan Motor and temperature rise by heat

radiation.

Use a vacuum cleaner or brush to remove dirt and dust between the fins. Be careful not to bend

the fins.

[i] CONDENSER COOLING FAN MOTOR

The Fan Motor cools the Air-cooled Condenser and sends air to condense refrigerant gas inside

the Condenser.

[j] DRIER

The Drier uses desiccants (molecular sieves + activated alumina) to absorb moisture in the

refrigeration circuit. The built-in filter also corrects foreign matter in the refrigeration circuit to

prevent troubles with valves clogged with dirt or moisture.

[k] SOLENOID VALVE

The Solenoid Valve is provided for pump down control to prevent refrigerant gas from remaining

inside the Evaporator and causing liquid return at restart.

[l] THERMOSTATIC EXPANSION VALVE

The Expansion Valve throttles high-pressure liquid refrigerant into low-temperature low-pressure

state by adiabatic expansion and maintains the proper amount of refrigerant supply depending

on the Evaporator load. The Thermostatic Expansion Valve controls the valve position to regulate

the superheat (difference between evaporating temperature and suction gas temperature). No

superheat control is available from outside.

To check the Expansion Valve for proper operation, remove the Bulb while the Compressor is

running. If the suction pressure rises, the Expansion Valve is working normally.

Note: Do not leave the Bulb removed for a long time while the Compressor is running. The

Compressor may fail due to liquid return.

[m] ACCESS VALVE

The Access Valve connects the inside and outside of the refrigeration circuit to allow evacuation,

recharge, and pressure measurement.

Note: When replacing (brazing) the Access Valve, remove the valve core to prevent the

rubber part from melting. The valve is sealed by the core only. Always cap the valve while

not in use. Tighten the seal nut to the torque of 9.81 - 12.26Nm to prevent gas leaks.

[n] RECEIVER TANK

The Receiver Tank temporarily stores excess liquid refrigerant which may be caused by a change

in ambient temperature. The Access Valve provided for servicing can also be used to check

the high-side pressure.
