Hoshizaki KM-1130MAK2 1181 lb/Day Air-Cooled Crescent Ice Machine
KM-1130MAK2
Product overview
The Hoshizaki KM-1130MAK2 is an air-cooled modular ice-making head that produces individual crescent cubes for beverage service. Its stainless steel exterior and double-sided stainless steel evaporator support commercial ice production of up to 1,181 lb per 24 hours at 70°F air / 50°F water. A compatible storage bin or dispenser and any required top kit are sold separately; this head has no built-in ice storage.
CycleSaver operation, EverCheck alerts and removable air filters support operation and routine upkeep. Keep the air intake, outlet and service access clear when planning the installation.
- 1,181 lb per day: Rated at 70°F air / 50°F water.
- 208–230V single-phase: Hardwired supply; no cord or plug included.
- 30-inch nominal width: Ice-making head only; storage bin sold separately.

Production and utility use
At 90°F air / 70°F water, this model uses 4.55 kWh and 22 gallons of potable water per 100 lb of ice. Output varies with installation conditions, ambient temperature and incoming water temperature. Daily production does not describe storage capacity; select the bin for the amount of ice that needs to be held between busy periods.
Installation and storage assembly
Install indoors on a level, securely attached compatible bin or dispenser, away from ovens, grills and other heat-producing equipment. Allow at least 12 inches behind, beside and above the head for airflow and service. Check the full dimensional drawing, panel projections, ice-drop opening, bin height and leg height before preparing the site. The nominal width alone does not establish bin or dispenser compatibility.
Confirm the exact bin, dispenser and top-kit combination with the installation manual before ordering. Keep the bin-control sensing area unobstructed and secure the head to the storage assembly.
Electrical and water connections
A licensed electrician must provide an independent, grounded 208–230V / 60Hz / single phase supply with 20A circuit protection. Connect the neutral and grounding conductors as directed by the wiring diagram; a receptacle alone is not a complete installation. Set the transformer voltage tap to match the incoming supply during commissioning.
If GFCI protection is required, use a GFCI breaker rather than a GFCI receptacle.
Provide a potable-water supply with an accessible shut-off valve and a separate gravity drain for the ice maker and storage bin. Drain piping must slope downward, remain vented as instructed and terminate with the required air gap. Follow the model’s connection drawing and local plumbing requirements; water treatment should match the site’s water quality.
Cleaning and maintenance
Clean the ice scoop daily, inspect the air filters every two weeks and wash dirty filters with warm water and a neutral cleaner. Wipe the exterior monthly. Have a qualified technician check external water filters and clean the underside, top kit and bin surfaces monthly and clean the bin-control lens as directed.
Have the ice maker and storage assembly cleaned and sanitized at least annually, with more frequent service when water quality or local sanitation requirements demand it. Follow the manual’s chemical concentrations, rinsing and sanitation sequence. Disconnect and lock out power before maintenance; switching the control off does not isolate every electrical load. Arrange draining and winterization before extended non-use or freezing conditions.
Have a qualified technician inspect and clean the condenser annually, inspect water hoses and clean or replace them as needed, and clean the inlet and cleaning-valve screens and clean and inspect the drain valve.
Warranty
Manufacturer coverage includes three years of parts and labor on the machine, five years of parts and labor on the evaporator, and five years of parts coverage on the compressor and air-cooled condenser. Register within 30 days of installation. Coverage is for the original owner/user in the United States, Canada, Puerto Rico and U.S. territories, subject to proper installation and maintenance and the written warranty terms and exclusions.
