Hoshizaki FS-1501MLJ-C 1386 lb/Day Serenity Remote-Cooled Cubelet Ice Machine
FS-1501MLJ-C
Product overview
The Hoshizaki FS-1501MLJ-C Serenity head makes medium cubelet ice for beverage service. With the separately sold SRC-14J, it produces up to 1,386 lb per day at 70°F air and 50°F water, or 1,125 lb at 90°F air and 70°F water. Locating the compressor and condenser outdoors reduces their heat and noise at the serving point.
The stainless steel exterior and auger provide durable construction, while EverCheck alerts support operation. Advanced CleanCycle24 flushes sediment for two seconds each hour; it complements scheduled cleaning and sanitizing rather than replacing them.
- Medium cubelet ice: Nugget-style ice for a compatible beverage dispenser or storage-bin installation.
- 30-inch nominal width: Match the mounting openings, support and complete installed envelope.
- Remote low-side system: The separate SRC-14J contains the compressor and air-cooled condenser.

Required components and mounting
This listing supplies one ice-making head only, with no built-in storage. Order the SRC-14J, refrigerant lines, a compatible bin or dispenser and any required adapter or top kit separately. Use a supporting assembly at least 30 inches wide, with its capacity and mounting approved for this exact head. Width alone does not establish compatibility.
Match the angled rectangular ice-drop zone and keep the ultrasonic sensor opening and sensing path unobstructed by adapters or risers. Use the exact bottom drawing to position both openings.
Confirm the full delivered head profile, rear connections, adapter height and supporting equipment before fit-out. Allow access for auger and cube-guide removal, with the installer checking the exact installation drawing and service clearances before cabinetry is built around the head. Install level on a firm foundation away from ovens, grills and other high-heat equipment.
Remote installation
Use the matched SRC-14J outdoors on a permanent, dry, ventilated site. Provide at least 24 inches at the front and rear for airflow and service. Confirm the delivered remote unit’s operating-temperature limits before choosing its location.
Keep the line set within 55 feet, measured fitting to fitting. The remote may be no more than 33 feet above or 10 feet below the head. For a rise greater than 20 feet, install the specified ⅝-inch suction-line S oil trap halfway up. The system uses ⅜-inch OD liquid and ⅝-inch OD suction lines; select HS-5323, HS-5324 or HS-5325 only after confirming the required length and fittings. A qualified refrigeration installer must braze, leak-test, evacuate and commission the system. Do not coil excess tubing.
Power, water and drainage
The head and remote unit require separate electrical supplies; power is not transferred between them. Connect the remote’s white lead to neutral and ground both units. Do not use an extension cord, adapter plug or removed ground pin on the head. If GFCI protection is required, use a GFCI breaker rather than a receptacle. Verify delivered electrical ratings and cord reach before locating the outlet. Power the remote condensing unit for at least four hours before startup.
Fit potable-water shutoff and drain valves, and select water treatment for local water quality. Route head and storage drains separately with vented tees, at least ¼ inch fall per horizontal foot and a minimum 2-inch vertical air gap at each outlet. Do not connect drains directly to a sewer.
Bin-control setup
The ultrasonic primary sensor and mechanical backup must both be commissioned for the selected bin or dispenser. Do not use the factory setting 1, a 5-inch shutdown distance, for a dispenser. Set and test the recommended full level for the actual dispenser and keep adapters outside the sensing path to prevent overflow or movement.
Cleaning and maintenance
Clean the scoop daily. Each month, check external water treatment and clean the exterior, sensor lens, underside and top-kit surfaces. Clean and sanitize the head and storage assembly at least every six months; check the drain pans, drains and extruding-head seal bolts at the same interval. Removed seal bolts must be replaced.
Arrange yearly qualified checks of valves, hoses, condenser, fasteners and upper-bearing wear. After three years, include both bearings, the lower O-ring, mechanical seal, cylinder and auger in annual inspections. Site conditions may require more frequent service. Disconnect power before service, follow the exact cleaning and rinsing procedure, wear the prescribed protection and never use ammonia-type cleaners. Discard cleaning and rinsing ice. Arrange proper draining for extended non-use or freezing conditions.
Limited warranty
Three years parts and labor on the machine, with five years parts on the compressor and air-cooled condenser coil, subject to the full warranty terms and applicable installation and serial-number eligibility. Coverage is for the original owner/user in the United States, Canada, Puerto Rico and U.S. territories. Register within 30 days of installation and retain installation records. Read the limited warranty.
