Hoshizaki KMD-410MWJ 449 lb/Day Water-Cooled Crescent Cube Ice Machine for Dispensers

Product overview

The Hoshizaki KMD-410MWJ is a water-cooled modular crescent-cube ice maker producing up to 449 lb per 24 hours at 70°F air and 50°F water. At 90°F air and 70°F water, production is 436 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 449 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.

Specifications

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.

Compatible installation options include the DB-130H dispenser and selected B-250SF, BD-300SF, B-500SF, B-700SF, B-800SF and B-900SF bins with the required top kit. Confirm the complete model-specific assembly and control clearance before ordering. The installer must connect the bin-control lead, position the deflector and verify operation.

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, left side and top; have the installer confirm the right-side clearance against the delivered model’s instructions before placement. Allow space to remove panels and move utility lines for service. Confirm the permitted ambient operating range for the delivered model before selecting a warm installation location. Drain and winterize the machine and water lines before freezing exposure or extended non-use.

Have a qualified electrician provide an independent, grounded 115V / 60Hz / single-phase hardwired supply with 20 A minimum circuit ampacity and 20 A maximum fuse/HACR protection. Connect line, neutral and ground, with the white lead connected to neutral. 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.

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. 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. Condenser inlet water must remain within 45–90°F. Condenser-water consumption is additional to the potable water used to make ice. No remote condenser is required.

Cleaning and maintenance

Clean the head and complete storage assembly at least once a year, more often where water quality or use requires it. Follow the complete cleaning, sanitizing and rinse procedure. Clean the storage-bin or dispenser liner and scoop with neutral cleaner and rinse thoroughly; use the storage assembly for ice only. Wipe the stainless steel exterior with a soft cloth and neutral cleaner as needed.

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.
