Hoshizaki KMS-1122MLJ 1151 lb/Day Serenity Remote-Cooled Crescent Ice Machine
KMS-1122MLJ
Product overview
The Hoshizaki KMS-1122MLJ Serenity Series modular ice head makes individual crescent cubes for beverage service. Its matched remote condensing unit houses the compressor and condenser outside the serving area, reducing their heat and noise at the head. A stainless steel exterior and KMEdge stainless steel evaporator support commercial use, with CycleSaver operation and EverCheck alerts.
This listing is for one ice-making head. The required SRK-12J or SRK-12J3, compatible ice bin or dispenser, refrigerant line set and any necessary adapter or top kit are sold separately. The head has no built-in ice storage.
- Up to 1,151 lb/day: Rated at 70°F air and 50°F water with the matched remote unit shown below.
- 22-inch nominal width: Check the full cabinet profile and connections before specifying the installation.
- Crescent ice: Individual cubes approximately 1½ × 1⅛ × ½ inches.
Production and resource use
Ratings are for the complete head-and-remote pairing over 24 hours. Warmer air and water reduce output; choose the pairing for the expected operating conditions.
| Remote unit | Ice at 70°F air / 50°F water | Ice at 90°F air / 70°F water | Energy per 100 lb | Potable water per 100 lb |
|---|---|---|---|---|
| SRK-12J | 1,151 lb/day | 1,075 lb/day | 4.2 kWh | 16.0 US gal |
| SRK-12J3 | 1,151 lb/day | 1,100 lb/day | 4.05 kWh | 16.0 US gal |
Energy and water figures are measured at 90°F air and 70°F water. These air-cooled remote units do not use a condenser-water circuit.

Fit and required components
The 18⅛-inch lower footprint is not the full head depth: the upper body extends to 21½ inches, with refrigerant connections beyond it. Check the complete stepped profile and below-head bin control against the dispenser or bin support.
Use a level, independently supported bin or dispenser with the correct ice-drop opening and manufacturer-specified adapter, mounting hardware and seals. Verify compatibility before ordering; matching the head width alone does not establish fit. Install and test the bin control so ice stops at the correct level. Side-by-side head installation is not recommended.
Allow at least 6 inches at the rear, sides and top of the head for service and airflow, plus room for field connections. Provide 24 inches of clearance around the remote condensing unit. Keep the head away from ovens, grills and other high-heat equipment.
Remote piping and electrical installation
Available brazed line sets HS-0250, HS-0251 and HS-0252 are 25, 35 and 55 feet long, respectively. The maximum line length is 66 feet. Locate the remote unit no more than 33 feet above or 10 feet below the head, measured fitting to fitting. A rise over 20 feet requires the specified suction-line oil trap halfway up the rise. Do not coil excess line.
A qualified installer must connect, leak-test, evacuate and charge the field lines using the exact model instructions. Match the refrigerant and delivered nameplates; the line set requires preparation and refrigerant before operation.
Connect building power to the remote condensing unit on its required independent, grounded circuit. The head receives power through the specified wire bundle; never connect it to a separate external supply. Ground both units and complete the bundle connections before energizing. If GFCI protection is required, use a GFCI breaker rather than a receptacle.
Single-phase J remote units use L1, neutral, L2 and ground. Three-phase J3 units use L1, L2, L3 and ground, with the transformer tap matched to the incoming voltage. Where a single-phase site lacks neutral, confirm the exact HS-5030 transformer-kit requirements before specifying the installation.
The matched remote units have 20A minimum circuit ampacity and maximum fuse/HACR breaker ratings. Confirm the delivered nameplate before electrical work.
Power the remote condensing unit for at least four hours before startup. Have the installer complete the leak, wiring and bin-control checks in the manual before making ice.
Water, drainage and care
Provide a potable-water supply with shutoff and drain valves. Run the head and bin or dispenser drains separately to an approved drain, with a vented tee, at least ¼ inch fall per foot on horizontal runs and a minimum 2-inch vertical air gap. Assess filtration for the local water supply; treatment equipment is separate.
Clean the scoop daily. Check external water filters and wipe the exterior monthly. Clean and sanitize the head and ice-storage assembly at least yearly, more often when water quality or local sanitation rules require. Inspect the inlet screen, hoses and remote condenser yearly and clean or replace components as needed.
Disconnect power before service. Follow the model-specific cleaning and sanitizing procedures, wear protective gloves and goggles, and do not use ammonia-type cleaners. Arrange proper draining and winterization for extended shutdown or freezing conditions. Store ice only in the bin or dispenser.
Limited warranty
Coverage for the original owner/user includes three years parts and labor on the machine, five years parts and labor on the evaporator, and five years parts on the compressor and air-cooled condenser coil, subject to the complete warranty terms. Register within 30 days of installation. Coverage applies in the United States, Canada, Puerto Rico and U.S. territories; improper installation, inadequate maintenance and other exclusions apply. Read the full limited warranty.
