II. GENERAL INFORMATION 1. CONSTRUCTION The Hoshizaki Cubelet Ice Dispenser, model DCM-270BAH-OS includes Water Supply, Freezer, Condensing, Storage, Dispensing and Control Assemblies. Fig. 1 Note: *Adjustable Legs Minimum height - 4" Maximum height - 5.3" Do not adjust exceeding the above recommendation.
2. OPERATION - How it works Water flows from the potable water source through the Water Supply Line Shut-off Valve, enters at the Water Inlet fitting and into the Water Reservoir. The Water Reservoir functions to maintain a constant water level inside the Freezer Assembly. Water from the Water Reservoir enters at the bottom of the Freezer. Heat is removed by the refrigeration process and ice forms inside the Freezer.
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) Be careful not to damage the panels when installing the ice dispenser. 2) Remove the package containing accessories. 3) Check that a 1A and a 0.5A spare fuse for the Transformer are provided in the small vinyl bag.
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°F to +90°F. Operation of the ice dispenser, for extended periods, outside of these normal temperature ranges may affect production capacity. IMPORTANT Sunlight, direct and indirect, can have an effect on the operation of the dispense sensors.
5. WATER SUPPLY AND DRAIN CONNECTIONS - See Fig. 3 • When the water supply is off, or if the pressure is below 10 PSIG, the protection circuit stops the operation of the ice dispenser. Wait until the proper water pressure is reached. • Water supply inlet is 1/2" female pipe thread (FPT). • A water supply line shut-off valve and drain valve should be installed. • Water supply pressure should be a minimum of 10 PSIG and a maximum of 113 PSIG. If the pressure exceeds 113 PSIG, use a pressure reducing valve.

7. START UP 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) Plug in and move the Power Switch, located on the left bottom of the Middle Front Frame, to the “ON” position. 4) Move the Ice Making Switch, located on the Control Box, to the “ICE” position.
8. PREPARING THE ICE DISPENSER FOR LONG STORAGE IMPORTANT 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. 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 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. 4. Fig.
IV. 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 WARNING 1. HOSHIZAKI recommends cleaning this unit at least twice a year. More frequent cleaning, however, may be required in some existing water conditions. 2.

See Fig. 6. 10) Pour the cleaning solution carefully into the Reservoir through the opening in the center of the Storage Bin up to the overflow level. (Overflowed solution can be seen in the Drain Pan.) 11) While waiting for 10 minutes to start icemaking process, wipe the Bin Liner and the Drip Plate using a clean cloth containing the cleaning solution.
3) Wait for 10 minutes to start icemaking process. Move the Ice Making Switch to the “ON” position, and start automatic icemaking process. Run the ice dispenser until it stops automatically. 4) Move the Ice Making Switch to the “FLUSH” position. 5) Wipe the Bin Liner and the Drip Plate using a clean cloth containing the sanitizing solution.
3. MAINTENANCE IMPORTANT This ice dispenser must be maintained individually, referring to the instruction manual and labels provided with the ice dispenser. 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. 2) Air Filter - See Fig. 7 A plastic mesh air filter removes dirt or dust from the air, and keeps the Condenser from getting clogged.
