  • 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 [F-2000MLH/-C only, two solenoid valves open] about 60 sec. after Gear Motor starts.
  • Page 31 [d] Bin Control operates, and about 6 sec. later, Compressor and Gear Motor stop simultaneously. (F-2000MLH/-C, two solenoid valves close.)
  • Page 32 [e] Low Water (Except Water-cooled Model where Compressor will operate intermittently)
  • Page 33 [f] When Flush Timer operates (for 15 min. every 12 hours) or when Flush Switch is moved to “FLUSH” position, Flush Water Valve opens and flushes Reservoir and Evaporator.
  • Page 34 [g] For single-phase machines, when 208-230V are supplied to Circuit Protect Relay, it protects the circuit from being miswired. If the power supply is properly connected, the contact of Circuit Protect Relay does not move even when the coil is energized.
  • Page 35 [h] When Pressure Switch opens, power supply to the control board is cut off causing the Compressor and Gear Motor to turn off immediately.

  • Page 58 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 recommends only virgin refrigerant or reclaimed refrigerant which meets ARI Standard No. 700-88 be used.

  • Page 59: Brazing

    2. BRAZING 1. Refrigerant R-404A itself is not flammable at atmospheric pressure and temperatures up to 176° F. 2. Refrigerant R-404A itself is not explosive or poisonous. However, when exposed to high temperatures (open flames) R-404A can be decom- posed to form hydrofluoric acid and carbonyl fluoride both of which are hazardous.

    VII. CLEANING AND MAINTENANCE 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 76: [Water-Cooled Models]

    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 fre- quent cleaning, however, may be required in some existing water conditions.
  • Page 77 For safety and maximum effectiveness, use the solution immediately after dilution. <STEP 2> Use the cleaning solution to remove lime deposits in the water system. 1) Turn off the power supply. 2) Close the Water Supply Line Shut-off Valve. 3) Remove all ice from the Storage Bin. 4) Remove the Front Panel and the Top Panel.
  • Page 78 Use 3/4 gal. of the sanitizing solution to sanitize the icemaker. 1) Close the Water Supply Line Shut-off Valve. 2) Remove the Control Water Valve by releasing the Fitting Nut. 3) Remove the Cover of the Reservoir. 4) Fill the Reservoir with the sanitizing solution. 5) Replace the Cover of the Reservoir and the Control Water Valve in their correct positions.
