Hoshizaki IM-544SAK 453 lb/Day Air-Cooled Square Cube Ice Machine
IM-544SAK
Product overview
The Hoshizaki IM-544SAK produces individual 1by1 square ice for beverage service. This stainless steel, air-cooled modular head pairs with a separately selected storage bin. EverCheck alerts support operation. One head is supplied; bins, top kits, additional heads and stacking kits are sold separately.
The square cubes measure approximately 28 × 28 × 32 mm. A small forming dimple is part of the ice-making process; dimensions are approximate.
- Ice shape: 1by1 square ice.
- Storage: Separate compatible bin required; not included.
- Nominal width: 44 inches; allow the specified ventilation and service space.

Daily production and storage are different measures. Select the machine for demand at the actual air and water temperatures, and allow for changes in operating conditions.
Installation and service access
Use a manufacturer-approved bin at least 44 inches wide, with the exact top kit, support and ice-drop opening checked before ordering. Large upright bins are not recommended for this head. Secure the supplied mounting brackets and bolts. Leave 6 inches behind, above and on the left, and 12 inches on the right; keep the front and right-side air filters accessible.
For an approved stack of two IM-544SAK heads, add one HS-5530 stacking kit; three heads require two kits. Additional heads and kits are separate. Each head needs its own electrical and water supply. Have the installer verify total height, bin support, utilities and refrigerant-safety requirements for the complete assembly.
Nominal cabinet dimensions do not include every utility projection or installation allowance. Check the exact drawing and delivered equipment before fit-out. Keep the machine away from ovens, grills and other high-heat equipment.
R290 siting requirements
The 140 g (4.9 oz) R290 charge is flammable. Provide a room floor area of at least 6.7 m² (72.1 ft²) for operation or storage of this single head. Do not install in a public corridor or lobby. Keep ventilation openings clear and avoid ignition sources in or near the equipment; storage spaces must not contain continuously operating ignition sources. Installation is limited to 2,000 m (6,561 ft) altitude. Use personnel trained for flammable-refrigerant service.
Power, water and drainage
Have a qualified installer confirm the delivered nameplate and required branch-circuit protection before hardwiring. Connect the white lead to neutral and ground the head. If GFCI protection is required, use a GFCI breaker rather than a receptacle.
Provide potable-water shutoff and drain valves. Supply water at 10–113 psig through at least ¼-inch nominal-ID copper tubing or equivalent; fit pressure reduction if needed. Select water treatment for local quality and leave enough line length for service pull-out.
Use at least ¾-inch nominal-ID hard drain pipe or equivalent, a vented tee, at least ¼ inch fall per horizontal foot and a minimum 2-inch vertical air gap to an approved drain. Run the head and bin drains separately. Do not connect directly to a sewer. Have a qualified plumber resolve water hammer before commissioning.
Operation and care
The bin-level control stops production when the storage area fills. Have the installer test the control during commissioning, and keep the sensing mechanism unobstructed. Do not run the water pump in WASH with an empty tank. Wait at least three minutes before restarting after a shutdown.
Clean the scoop daily. Inspect the air filters every two weeks and wash them when dirty. Check external water treatment and wipe the exterior monthly. At least yearly, arrange qualified cleaning and sanitizing of the machine and storage bin, cleaning of the inlet screen, and inspection of hoses and the condenser. Increase the frequency for water quality and site conditions.
Cleaning and sanitizing are separate steps. Disconnect power before service, follow the exact chemical and rinse instructions, wear protective gloves and goggles, and do not use ammonia-type cleaners. Arrange proper draining before prolonged non-use or freezing conditions. Bin equipment and water-treatment accessories are selected separately.
Limited warranty
Coverage for the original owner/user includes three years parts and labor on the IM machine and evaporator, plus five years parts on the compressor and air-cooled condenser, subject to the complete terms. Coverage applies in the United States, Canada, Puerto Rico and U.S. territories. Register within 30 days of installation and retain installation records; improper installation, utility faults and inadequate maintenance are among the exclusions. Read the IM limited warranty.
