Hoshizaki KM-1601MRJZ3 1653 lb/Day Remote-Cooled Modular Crescent Ice Machine - 3 Phase

Product overview

The Hoshizaki KM-1601MRJZ3 makes individual crescent ice with a stainless steel evaporator and a durable stainless steel exterior. This remote air-cooled modular ice-making head supplies a separate compatible storage bin or dispenser; it does not include built-in ice storage. Rated production reaches 1,653 lb per 24 hours at 70°F air / 50°F water. Its URC-22FZ remote condenser is sold separately and places condenser heat rejection away from the ice-making head.

CycleSaver ice-making operation and the EverCheck alert system support day-to-day operation. Match the machine to the site utilities and provide access for cleaning, condenser service and bin maintenance.

• ❄ 1,653 lb per day: Rated at 70°F air / 50°F water.
• ⚡ 60 Hz three-phase: Hardwired supply; no cord or plug included.
• ↔ Remote air-cooled: URC-22FZ condenser sold separately.

Specifications

Production and utility use

At 90°F air / 70°F water, consumption is 4.09 kWh and 18.0 gallons of potable water per 100 lb of ice. Production changes with air and water temperatures, water quality and installation conditions. Daily output is not storage capacity; select a bin for the amount of ice the operation needs to hold.

Installation and bin selection

Install the ice-making head indoors on a firm, level, properly supported bin or dispenser, away from ovens, grills and other high-heat equipment. Allow at least 6 inches at the rear, sides and top for airflow and service. Verify the complete installed dimensions, connection projections, bin height and legs before preparing the location.

Confirm the exact bin, top kit and ice-drop opening before ordering. A shared nominal width does not establish compatibility. Use the bin and top-kit chart with the installation manual; some combinations require a top kit or a two-unit arrangement. Storage bins, dispensers and top kits are sold separately.

Electrical requirements

Have a licensed electrician provide an independent, properly grounded 208–230V / 60Hz / three phase supply with 20A circuit protection. The machine must be hardwired on site; a receptacle alone is not a complete installation. Match the delivered nameplate, transformer settings and wiring diagram. If GFCI protection is required, use a GFCI breaker rather than a GFCI receptacle.

This model requires three-phase power. Have the electrician verify incoming phase connections and the transformer voltage setting against the machine wiring diagram before startup.

Remote condenser and line set

Use the matching URC-22FZ remote condenser and a compatible brazed line set, both sold separately. Provide a dry, well-ventilated permanent condenser location with at least 24 inches of clearance at the front and rear. The maximum vertical separation is 33 feet above or 10 feet below the ice-making head, measured fitting to fitting. Standard line sizing and charge cover runs up to 66 feet; longer runs, up to 100 feet, require the line-size and refrigerant adjustments in the manual. Have a qualified refrigeration technician select, braze, evacuate and commission the system.

The remote condenser receives its fan-motor electrical supply from the ice machine. Complete condenser connections before energizing the machine, and supply power to the ice-making head for at least four hours before startup to protect the compressor.

Water supply and drainage

Connect potable water only through the ½-inch FPT inlet, with shutoff and drain valves. Use at least ⅜-inch nominal-ID copper supply tubing or equivalent. Reduce pressure above 113 PSIG. Select filtration for local water quality and keep the piping accessible for service.

The ice-machine drain has a ¾-inch FPT outlet and requires at least ¾-inch nominal-ID hard pipe or equivalent. Provide a vented tee, a ¼-inch fall per horizontal foot and at least a 2-inch vertical air gap above the floor drain. Keep ice-machine and storage-bin drains separate; do not connect directly to the sewer. The condensate drain may join the ice-machine drain or run separately as directed in the manual.

Cleaning and maintenance

Clean and rinse the ice scoop daily. Check external water filters and wipe the exterior, underside, top kit and bin door monthly. Clean and rinse the bin-control lens monthly. Arrange cleaning and sanitation of the ice machine and storage bin at least yearly; water quality, the environment and local sanitation rules may require more frequent service. Have the water-inlet screen, hoses and condenser inspected yearly and cleaned as needed.

Disconnect electrical power before servicing, follow the complete cleaning procedure and chemical labels, and do not use ammonia-type cleaners. Automatic controls do not replace sanitation. Have the water system drained for prolonged shutdowns or freezing conditions.

Limited warranty

Coverage includes three years of parts and labor on the machine, five years of parts and labor on the KM evaporator, and five years of compressor and air-cooled condenser parts. Labor for compressor or condenser coverage beyond year three is excluded. Register within 30 days of installation. Coverage applies to the original owner/user in the United States, Canada, Puerto Rico and U.S. territories, subject to proper installation, use, maintenance and the written terms and exclusions.
