28 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.
29 [b] When Reservoir has been filled, Gear Motor starts immediately..
30 [c] Compressor starts about 60 sec. after Gear Motor starts..
31 [d] Bin Control operates, and about 6 sec. later, Compressor and Gear Motor stop simultaneously..
32 [e] Low Water (Except Water-cooled Model)..
33 [f] Low Water (Water-cooled Model), or Dirty Air Filter (Air-cooled Model), Pressure Switch to “OPEN”, Compressor and Gear Motor operates intermittently.
34 [g] When Flush Switch is moved to “FLUSH” position, Flush Water Valve opens and flushes Reservoir and Evaporator..
35 [h] When Flush Timer operates (for 15 min. every 12 hours)..
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.
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..

53 3. OTHERS PROBLEM POSSIBLE CAUSE REMEDY [1] Abnormal noise a) Fan Motor 1. Bearing worn out. 1. Replace. 2. Fan blade deformed. 2. Replace fan blade. 3. Fan blade does not move freely. 3. Replace. b) Compressor 1. Bearings worn out, or cylinder valve broken.
54 VI. REMOV AL AND REPLACEMENT OF COMPONENTS 1. SERVICE FOR REFRIGERANT LINES [a] REFRIGERANT RECOVERY [EXCEPT F-1000MLF(-C)] The icemaker unit is provided with two Refrigerant Access Valves - one on the low-side and one on the high-side line.
55 2) Turn on the Vacuum Pump. Never allow the oil in the Vacuum Pump to flow backward. 3) Allow the Vacuum Pump to pull down to a 29.9" Hg vacuum. Evacuating period de- pends on pump capacity. 4) Close the Low-side Valve and High-side Valve on the Service Manifold.
56 3. REMOV AL AND REPLACEMENT OF COMPRESSOR IMPORT ANT 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.
57 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.
58 5. REMOV AL AND REPLACEMENT OF EXP ANSION V AL VE IMPORT ANT 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.
59 6. REMOV AL AND REPLACEMENT OF W A TER REGULA TING V AL VE - W A TER-COOLED MODEL ONL Y IMPORT ANT 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.
60 7. REMOV AL AND REPLACEMENT OF CONDENSING PRESSURE REGULA TOR (C.P .R.) - REMOTE AIR-COOLED MODEL ONL Y IMPORT ANT 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.
61 8. REMOV AL AND REPLACEMENT OF EV APORA TOR ASSEMBL Y 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.
62 13) Recover the refrigerant and store it in an approved container, if required by an applicable law. IMPORT ANT 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.
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. W ARNING 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.
64 Auger Mechanical Seal O-ring Bearing - Lower Bolt Washer Coupling - Spline Rubber O-ring Nylon Ring Bolt Washer Cutter Extruding Head Washer Socket Head Cap Screw Evaporator Washer Socket Head Cap .
65 9. REMOV AL AND REPLACEMENT OF F AN MOTO R 1) Turn off the power supply and remove the panels. 2) Remove the wire connectors from the Fan Motor leads. 3) Remove the Fan Motor Bracket and Fan Motor. 4) Install the new Fan Motor. 5) Replace the Fan Motor Bracket and the wire connectors.
66 1 1. REMOV AL AND REPLACEMENT OF FLUSH W A TER V AL VE 1) Turn off the power supply, remove the panels and close the Water Supply Line Shut- off Valve. 2) Remove the Clamp and disconnect the Hose from the Flush Water Valve. Note: Water may still remain inside the Evaporator.
67 VII. MAINTENANCE AND CLEANING INSTRUCTIONS IMPORT ANT Ensure all components, fasteners and thumbscrews are securely in place after any maintenance or cleaning is done to the equipment.
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.
69 2. CLEANING INSTRUCTIONS IMPORT ANT Ensure all components, fasteners and thumbscrews are securely in place after any maintenance or cleaning is done to the equipment. W ARNING 1. HOSHIZAKI recommends cleaning this unit at least once a year. More frequent cleaning, however, may be required in some existing water conditions.
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.
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.
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.
73 3. MAINTENANCE IMPORT ANT 1. This icemaker must be maintained individually, referring to the instruction manual and labels provided with the icemaker.
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.
