II. GENERAL INFORMATION 1. CONSTRUCTION Hoshizaki Cubelet Ice Dispensers, models DCM-500BAF, DCM-500BWF, DCM-750BAF and DCM-750BWF include Water Supply, Freezer, Condensing, Storage, Dispensing and Control Assemblies. Fig.
2. OPERATION - How it works Water flows from a potable water source through the Water Supply Line Shut-off Valve, enters at the water inlet fitting and on to the Water Supply Assembly. The water supply functions to maintain a constant water level inside the Freezer Assembly. Water from the water supply enters at the bottom of the Freezer and changes into ice by heat-exchanging refrigerant from the Condensing Assembly.
III. INSTALLATION AND OPERATING INSTRUCTIONS 1. CHECKS BEFORE INSTALLATION IMPORTANT 1. Remove shipping carton, tape(s) and packing. If packing material is left in the ice dispenser, it will not work properly. 2. Ensure all components, fasteners and thumbscrews are securely in place. 1) Remove the Upper Front, Top and Side Panels to prevent damage when installing the ice dispenser. (See “2. HOW TO REMOVE PANELS.”) 2) Remove the package containing accessories.
3. LOCATION WARNING This ice dispenser is not intended for outdoor use. Normal operating ambient temperature should be within +45°F to +100°F; normal operating water temperature should be within +45°C to +90°C. Operation of the ice dispenser, for extended periods, outside of these normal temperature ranges may affect production capacity. For best operating results: • Ice dispenser should not be located next to ovens, grills or other high heat producing equipment.
5. CABINET STAND When placing the ice dispenser on the Cabinet Stand: 1) Attach four adjustable legs to the Cabinet Stand. (Cabinet Stand accessory) 2) Remove the protective plastic film from the panels. 3) Remove the Front Panel by lifting up and pulling toward you. 4) Place the ice dispenser on the Cabinet Stand. Combination: SD-450 . . . . . . DCM-500BAF, BWF SD-700 . . . . . . DCM-750BAF, BWF 5) You must secure the ice dispenser to the Cabinet Stand with four bolts (Cabinet Stand accessory). 6.

6. ELECTRICAL CONNECTION - See Fig. 6 WARNING This ice dispenser requires a ground that meets the national and local electrical code requirements. To prevent possible electrical shock to individuals or extensive damage to the equipment, install a proper ground wire to the ice dispenser. • This ice dispenser must have a separate power supply or receptacle of proper capacity. See the Nameplate. • Usually an electrical permit and services of a licensed electrician are required. Fig.
7. WATER SUPPLY AND DRAIN CONNECTIONS - See Fig. 7 and 8 • Water supply inlet is 1/2" female pipe thread (FPT). A strainer should be installed with the clean-out plug down. Locate the strainer in the water supply line, next to the ice dispenser with the arrow on the strainer in the direction of the water flow. Note: a) A Part Code 311166A01 strainer is an optional extra. b) On water-cooled models, a 1/2" FPT is provided for the Condenser Water Inlet.

9. START UP - See Fig. 9 WARNING 1. All parts are factory-adjusted. Improper adjustments may result in failure. 2. If the unit is turned off, wait for at least 3 minutes before restarting the ice dispenser to prevent damage to the Compressor. 1) Clean the Storage Bin. 2) Open the Water Supply Line Shut-off Valve. 3) Turn on the power supply. 4) Remove the Front Panel. 5) Turn on the Power Switch on the Control Box.
11) Check if there is any abnormal noise from the Compressor, Fan Motor or Gear Motor(s) after 30 minutes of running. 12) Move the Dispense Mode Switch, located at the bottom of the Middle Front Panel, to the “PORTION” or “CONTINUOUS” position. 13) Press the Push Button to dispense ice, and the dispensing mechanism will operate. 14) Press the Push Button to dispense water, and the Water Valve will open. Fig.
IMPORTANT Leaving ice in long storage may result in the formation of an ice block or bridge due to wet ice. Use the Control Switch to produce new ice at any time, using the following instructions: 1. Turn the Control Switch to “OFF” in advance so that the stored ice can be used up when your serving is over. 2. Turn the Control Switch to “ICE” a few hours before you need a full Storage Bin, because the Storage Bin takes time to fill. 10.
11. PREPARING THE ICEMAKER FOR LONG STORAGE - See Fig. 11 and 12 WARNING When shutting off the ice dispenser for an extended time, drain out all water from the water line and remove the ice from the Storage Bin. The Storage Bin should be cleaned and dried. Drain the ice dispenser to prevent damage to the water supply line at sub-freezing temperatures, using air or carbon dioxide gas. Shut off the ice dispenser until the proper ambient temperature is resumed. 1) Close the Water Supply Line Shut-off Valve.
IMPORTANT Before operating the dispenser next time, check that the Water Supply Line Drain Valve is closed, and open the Water Supply Line Shut-off Valve. Note: When shutting off the ice dispenser at sub-freezing temperatures, run the ice dispenser with the Water Supply Line Shut-off Valve closed, and blow out the water inlet line, by using air pressure. See Fig. 12. Fig.
V. CLEANING AND MAINTENANCE INSTRUCTIONS IMPORTANT Ensure all components, fasteners and thumbscrews are securely in place after any maintenance or cleaning is done to the equipment. 1. CLEANING INSTRUCTIONS [a] WATER SYSTEM WARNING 1. Clean and sanitize the ice dispenser Water System at least twice a year, by using a recommended cleaner and sanitizer. 2. To prevent injury to individuals, do not use any ammonia type cleaners. 3.
8) Wait for 10 minutes before starting the icemaking process. Then turn on the Power Switch and move the Control Switch to the “ICE” position. Run the ice dispenser until it stops automatically. Note: This ice dispenser will not run without the Front Panel. Replace the Top Panel and the Front Panel. 9) Repeat Step 5). 10) Pour water into the Reservoir to rinse the cleaning solution, and drain the water system. See 5). 11) Dilute approximately 0.82 fl. oz. of a 5.25% Sodium Hypochlorite Solution with 1.
[b] STORAGE BIN - Following Cleaning Procedures for Water System 1) Remove the Front Cover of the Storage Bin. 2) Remove the thumbscrews, first from the vertical plane and then from the horizontal plane of the Motor Brackets. Move the Agitating Motor(s) and the Dispensing Motor toward you. Then remove the Agitator(s) and the Dispensing Auger. See Fig. 13. Note: Models DCM-750BAF and BWF are provided with two Agitators, and models DCM-500BAF and BWF with one Agitator. Fig.
6. Remove the Spout Cover and, the black Ice Dispensing Spout and the Water Dispensing Nozzle. See Fig. 16. Fig. 16 7) Immerse the parts removed in the above steps 2) through 6) in the cleaning and sanitizing solution for about 15 minutes each. 8) Rinse these parts thoroughly with clean water. 9) Wipe thoroughly the Shutter located above the Ice Dispensing Spout. 10) Reassemble the Bin Control Bracket Assembly.
2. MAINTENANCE IMPORTANT 1. This ice dispenser must be maintained individually, referring to the instruction manual and labels provided with the ice dispenser. 2. To obtain optimum performance of this ice dispenser, the following consumable parts need periodic inspection, maintenance and replacement: Extruding Head Housing Gear Motor Auger Mechanical Seal These parts should be inspected at least once a year or every 10,000 hours of operation.
3) Air Filter (Air-cooled model only) - See Fig. 17. A plastic mesh air filter removes dirt or dust from the air and keeps the Condenser from getting clogged. As the filter becomes clogged, the ice dispenser’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. 4)Condenser (Air-cooled model only) Check the Condenser once a year, and clean if required by using a brush or vacuum cleaner.
