Hoshizaki KM-1900SAJ3 1865 lb/Day Air-Cooled Stackable Crescent Ice Machine - 3 Phase

Product overview

The Hoshizaki KM-1900SAJ3 makes individual crescent ice with a double-sided stainless steel evaporator and a stainless steel exterior. This air-cooled stackable ice-making head requires a separate compatible storage bin or dispenser; it has no built-in ice storage. Production reaches 1,865 lb per 24 hours at 70°F air / 50°F water. Removable air filters give access for routine condenser-airflow maintenance.

The factory-installed ultrasonic bin control can be adjusted on site. CycleSaver operation, the EverCheck alert system and CleanAssist cleaning support day-to-day ice production and maintenance.

• ❄ 1,865 lb per day: Rated at 70°F air / 50°F water.
• ⚡ 60 Hz three-phase: Hardwired electrical connection.
• ↔ Air-cooled: Removable air filters.

Specifications

Installation and stacking

Install 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. Check the complete drawing for panel projections, utility connections and the total installed height with the selected bin and legs.

Two compatible heads can be stacked to increase production in the same floor space. Have the installer confirm the exact pairing, support, ice-drop opening, securing brackets and bin-control wiring before ordering; the stacking procedure depends on the models and bin-control configuration. An additional head, storage bin and any required top kit are sold separately.

Use the bin and top-kit chart together with the installation manual to select the storage bin and top arrangement. Nominal width alone does not establish fit; confirm single-head or stacked configuration and the required adapters.

Bin-control setup

Have the installer set and test the ultrasonic bin control for the selected storage bin or dispenser before operation. The factory setting 1 shuts down at 12 inches from the sensor for standard storage bins; do not use this setting for a dispenser. Measure and configure dispenser ice levels using the manual to prevent machine movement, water leakage or ice overflow. Keep top kits and risers clear of the sensor lens and sensing path.

Electrical requirements

Have a licensed electrician provide an independent, properly grounded 208–230V / 60Hz / three phase supply. The minimum circuit / maximum fuse rating is 20A. Match the delivered nameplate and wiring diagram. The electrical connection must be hardwired; no cord or plug is included. Where GFCI protection is required, use a GFCI breaker rather than a GFCI receptacle.

This three-phase model requires the transformer voltage setting and incoming phase connections to be checked against its wiring diagram before startup.

Water supply and drainage

Connect potable water through the ½-inch FPT inlet using at least ⅜-inch nominal-ID copper tubing or equivalent. Provide shutoff and drain valves and leave the piping accessible for service. Reduce pressure above 113 PSIG; do not operate with the supply turned off or below 10 PSIG.

The ice-making drain uses a ¾-inch FPT outlet and 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. Run ice-machine, bin and condenser-water drains separately; do not pipe 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. Inspect the removable air filters every two weeks; wash with warm water and neutral cleaner when dirty. Check external water filters and clean the bin-control lens, exterior, underside, top kits and bin door monthly. Clean and sanitize the head and storage bin at least yearly; water quality, operating conditions and local sanitation rules may require more frequent service. Have the inlet screen, hoses and condenser inspected yearly and cleaned as needed.

Disconnect and lock out electrical power before service. Follow the complete cleaning procedure and chemical labels, wear liquid-proof gloves and goggles, and do not use ammonia-type cleaners. CleanAssist does not replace sanitation. Drain the water system 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. Compressor and condenser labor 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.
