Hoshizaki KMD-860MWJ 940 lb/Day Water-Cooled Crescent Ice Machine for Dispensers
KMD-860MWJ
Product overview
The Hoshizaki KMD-860MWJ is a water-cooled modular crescent-cube ice maker producing up to 940 lb per 24 hours at 70°F air and 50°F water. At 90°F air and 70°F water, production is 862 lb per 24 hours. This product supplies one ice-making head; a compatible dispenser or storage bin and the required top kit are selected separately.
The stainless steel exterior and individual crescent cubes suit a separately configured ice-storage or dispensing installation. A mechanical bin-control assembly monitors the ice level. The installer must fit or commission the control for the selected storage assembly and keep its full operating travel clear.
- Up to 940 lb/day: Rated at 70°F air / 50°F water.
- Water-cooled system: Independent condenser-water circuit required.
- Modular head only: Dispenser or storage bin and top kit sold separately.

Daily production is not storage capacity. Output and utility use vary with air and water temperatures, water quality and installation. Confirm the complete head, top kit and storage-assembly envelope, utility projections and service access before final fit-out.
Dispenser or bin selection
Match the exact head, top kit, ice-drop opening, bin-control position and mounting pattern to the selected dispenser or bin. A nominal width match alone does not establish compatibility. Secure both assemblies and test the bin control during commissioning. Keep the ice path and control movement or sensing area clear.
Use a storage assembly at least 30 inches wide. The B-500 series is a recommended bin range. The bin/dispenser and any required top kit are sold separately; verify the exact mounting arrangement before ordering.
B-1500SS and B-1650SS applications require two heads. This product supplies one head, not a complete two-machine installation.
Installation and electrical supply
Install the head indoors on a firm, level support away from ovens, grills and other high-heat equipment. Leave at least 6 inches at the rear, both sides and top. Allow space to remove panels and move utility lines for service. Operate the head in a 45–100°F room. Drain and winterize the machine and water lines before freezing exposure or extended non-use.
Have a qualified electrician provide an independent, grounded 208–230V / 60Hz / single-phase hardwired supply with 20 A minimum circuit ampacity and 20 A maximum fuse/HACR protection. Use the specified L1, L2 and ground connections, with no supply neutral, and set the transformer tap for the incoming voltage. The ⅞-inch supply opening accepts ½-inch trade-size conduit. Match the delivered nameplate and applicable codes. If GFCI protection is required, use a GFCI breaker rather than a receptacle.
Water supply and drainage
Supply potable water at 45–90°F and 10–113 PSIG through at least ¼-inch nominal-ID copper tubing or equivalent, with shutoff and drain valves. Correct water hammer and select water treatment for local conditions. Provide enough utility-line allowance for service movement.
Use at least ¾-inch nominal-ID hard pipe or equivalent for the head drain. Keep head and storage drains independent, with vented tees, a ¼-inch fall per horizontal foot and at least a 2-inch vertical air gap at each pipe end above an approved drain. Do not connect drains directly to the sewer.
Route the separate ⅝-inch-OD condensation outlet into the head drain or a separate drain using the installation-manual arrangement.
Condenser-water circuit
Provide a separate condenser-water supply and drain or closed-loop return. Use at least ¼-inch nominal-ID copper tubing or equivalent for supply and closed return, or hard pipe for open drainage. Keep open condenser drainage independent of the head and storage drains. Confirm the actual condenser outlet fitting before plumbing. Include shutoff and drain valves at both ends of a closed-loop installation.
A closed loop requires at least 4 GPM, at least 10 PSIG inlet-to-return pressure differential and less than 30% glycol. Keep condenser inlet water at or above 45°F; have qualified personnel confirm a 104–115°F outlet temperature five minutes into the freeze cycle. Condenser-water consumption is additional to the potable water used to make ice. No remote condenser is required.
Cleaning and maintenance
Clean and thoroughly rinse the scoop daily. Each month, check external water filters and clean the exterior, underside of the head and top kit, and the storage door or snout. Keep the mechanical bin-control paddle unobstructed.
Clean and sanitize the head and storage assembly at least annually, with more frequent service when water quality or sanitation requirements demand it. Annual maintenance includes the inlet screen, hoses and condenser. Follow the model-specific cleaning and sanitizing sequence.
Do not use ammonia-type cleaners. Have qualified service personnel isolate and lock out power before maintenance, follow the prescribed procedures and secure every component, fastener and thumbscrew afterward. Follow the complete draining and winterization instructions before extended non-use or freezing conditions.
Limited warranty
Limited coverage provides three years of machine parts and labor, five years of evaporator parts and labor, and five years of compressor parts for the original owner/user. Register within 30 days of installation and retain installation records. Standard coverage applies in the United States, Canada, Puerto Rico and U.S. territories. Travel, mileage and premium labor are excluded, as are damage from improper installation, utilities or maintenance. Review the written warranty for start-date rules and full terms.
