Page 28: Sequence Of Electrical Circuit
3. SEQUENCE OF ELECTRICAL CIRCUIT [a] When Power Switch is moved to “ON” position and Flush Switch to “ICE” position, water starts to be supplied to Reservoir. - Page 29 [b] When Reservoir has been filled, Gear Motor starts immediately.
- Page 30 [c] Compressor starts about 60 sec. after Gear Motor starts.
- Page 31 [d] Bin Control operates, and about 6 sec. later, Compressor and Gear Motor stop simultaneously.
- Page 32 [e] Low Water (Except Water-cooled Model).
- Page 33 [f] Low Water (Water-cooled Model), or Dirty Air Filter (Air-cooled Model), Pressure Switch to “OPEN”, Compressor and Gear Motor operates intermittently.
- Page 34 [g] When Flush Switch is moved to “FLUSH” position, Flush Water Valve opens and flushes Reservoir and Evaporator.
- Page 35 [h] When Flush Timer operates (for 15 min. every 12 hours).
- Page 36 [i] When 208-230V are supplied to Circuit Protect Relay, it protects the circuit from miswiring. If the power supply is properly connected, the contact of Circuit Protect Relay does not move even when the coil is energized.
- Page 37 [j] When input voltage is too low, (Less than 70%), Gear Motor Fuse (1.5A) is blown causing the Compressor and Gear Motor to turn off immediately.

Page 54: Removal And Replacement Of Components
VI. REMOVAL AND REPLACEMENT OF COMPONENTS Ensure all components, fasteners and thumbscrews are securely in place after the equipment is serviced. 1. The Polyol Ester (POE) oils used in R-404A units can absorb moisture quickly. Therefore it is important to prevent moisture from entering the system when replacing or servicing parts. -
Page 55: Brazing
5) Disconnect the Vacuum Pump, and attach a Refrigerant Service Cylinder to the High-side line. Remember to loosen the connection, and purge the air from the Hose. See the Nameplate for the required refrigerant charge. Hoshizaki recom- mends only virgin refrigerant or reclaimed refrigerant which meets ARI Standard No. -
Page 56: Removal And Replacement Of Compressor
3. REMOVAL AND REPLACEMENT OF COMPRESSOR Always install a new Drier every time the sealed refrigeration system is opened. Do not replace the Drier until after all other repairs or replacement have been made. 1) Turn off the power supply, and remove the panels. 2) Remove the Terminal Cover on the Compressor, and disconnect the Compressor Wiring. -
Page 57: Removal And Replacement Of Drier
14) Evacuate the system, and charge it with refrigerant. For the air-cooled and water-cooled models, see the Nameplate for the required refrigerant charge and type. For the remote air-cooled models, see the label on the Control Box. 15) Connect the Terminals to the Compressor, and replace the Terminal Cover in its correct position. -
Page 58: Removal And Replacement Of Expansion Valve
5. REMOVAL AND REPLACEMENT OF EXPANSION VALVE Sometimes moisture in the refrigerant circuit exceeds the Drier capacity and freezes up at the Expansion Valve. Always install a new Drier every time the sealed refrigeration system is opened. Do not replace the Drier until after all other repairs or replacement have been made. -

8. REMOVAL AND REPLACEMENT OF EVAPORATOR ASSEMBLY 1) Turn off the power supply. 2) Remove the panels. 3) Move the Flush Switch to the "FLUSH" position. 4) Turn on the power supply and drain out all water from the water line. 5) Turn off the power supply. - Page 62 13) Recover the refrigerant and store it in an approved container, if required by an applicable law. Always install a new Drier every time the sealed refrigeration system is opened. Do not replace the Drier until after all other repairs or replacement have been made.
- Page 63 25) Remove the three Socket Head Cap Screws securing the Gear Motor. 26) Assemble the removed parts in the reverse order of the above procedure. Be careful not to scratch the surface of the O-ring, or it may cause water leaks. Handle the Mechanical Seal with care not to scratch nor to contaminate its contact surface.

Page 67: Maintenance And Cleaning Instructions
VII. MAINTENANCE AND CLEANING INSTRUCTIONS Ensure all components, fasteners and thumbscrews are securely in place after any maintenance or cleaning is done to the equipment. 1. PREPARING THE ICEMAKER FOR LONG STORAGE When shutting off the icemaker for an extended time, drain out all water from the water line and remove the ice from the Storage Bin. - Page 68 [Water-cooled Models] 1) Turn off the power supply and wait for 3 minutes. 2) Turn on the power supply and wait for 20 seconds. 3) Close the Water Supply Line Shut-off Valve. 4) Open the Drain Valve and quickly blow the water supply line from the Drain Valve to drain water in the Condenser.

Page 69: Cleaning Instructions
Ensure all components, fasteners and thumbscrews are securely in place after any maintenance or cleaning is done to the equipment. 1. HOSHIZAKI recommends cleaning this unit at least once a year. More frequent cleaning, however, may be required in some existing water conditions. - Page 70 6) Turn on the power supply and drain out all water from the water line. 7) Turn off the power supply. 8) Remove the Control Water Valve by releasing the Fitting Nut. Do not lose the Packing. 9) Remove the Cover of the Reservoir. 10) Fill the Reservoir with the cleaning solution.
- Page 71 5) Replace the Cover of the Reservoir and the Control Water Valve in their correct position. 6) Move the Flush Switch to the “ICE” position. 7) Replace the Top Panel and the Front Panel in their correct position. 8) Allow the icemaker to set for about 10 minutes before the operation. Then, turn on the power supply, and make ice using the solution until the icemaker stops icemaking.
- Page 72 6) Remove the two Thumbscrews, Plate, and Gasket at the top of the Ice Chute, and then remove the Bin Control Assembly by sliding it slightly toward the Spout and lifting it off. 7) Disassemble the Bin Control Assembly by removing the two Snap Pins, Shaft and Activator.

Page 73: Maintenance
Consult with your local distributor about inspection and maintenance service. To obtain the name and phone number of your local distributor, call Hoshizaki Technical Support at 1-800-233-1940. 1) Stainless Steel Exterior To prevent corrosion, wipe the exterior occasionally with a clean and soft cloth. Use a damp cloth containing a neutral cleaner to wipe off oil or dirt build up. - Page 74 3) Air Filter (Air-cooled model only) 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. Check the filter at least twice a month. When clogged, use warm water and a neutral cleaner to wash the filter.
