Hoshizaki KMD-705MRJZ 727 lb/Day Remote-Cooled Crescent Ice Machine for Dispensers
KMD-705MRJZ
Product overview
The Hoshizaki KMD-705MRJZ is a remote air-cooled modular crescent-cube ice maker producing up to 727 lb per 24 hours at 70°F air and 50°F water. At 90°F air and 70°F water, production is 670 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. Factory-installed ultrasonic bin sensing allows the shutoff level to be set for the selected storage assembly. CleanAssist supports the cleaning sequence, followed by the separate sanitizing and rinse procedure.
This remote model requires the separately sold URC-9FZ condenser and a matched line set. The head, condenser, piping and electrical interconnections must be installed and commissioned as one compatible system.
- Up to 727 lb/day: Rated at 70°F air / 50°F water.
- Remote air-cooled system: URC-9FZ remote condenser sold separately.
- 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 and BD-500 series are recommended bin ranges. The bin/dispenser and any required top kit are sold separately; verify the exact mounting arrangement before ordering.
Set the ultrasonic sensor for the actual bin or dispenser application. A storage-bin setting is not automatically correct for a dispenser. Keep the lens and required openings unobstructed and confirm that the selected shutoff level prevents overflow, leakage or movement of the head.
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 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.
Remote condenser and line set
Use the URC-9FZ with the matched brazed line set, both sold separately. Install the condenser outdoors within −20–122°F and leave at least 24 inches clear in front and behind, with full service access. Limit elevation to 33 feet above or 10 feet below the head, measured fitting to fitting.
Use ⅜-inch-OD liquid and ½-inch-OD discharge lines up to 100 feet; runs over 66 feet require the specified refrigerant-charge adjustment. Have qualified technicians braze, leak-test, evacuate and commission the system. Insulate the lines separately, provide a service loop and avoid traps, kinks or coiled excess.
Complete condenser wiring and grounding before energizing the head. The condenser fan receives its supply from the head; do not connect it to an external power source. Keep the head powered for at least four hours before startup to protect the compressor.
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. Clean and thoroughly rinse the ultrasonic bin-control lens monthly.
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. CleanAssist cleaning must be followed by the separate sanitizing and rinse 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. Applicable air-cooled condenser parts are also covered for five years. 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.
