Orders that ship directly from a manufacturer normally have a firm shipping estimate but those dates are subject to change due to manufacturer production, inventory or shipping. We do our best to estimate ship dates but orders shipping directly from the manufacturer can have unexpected delays.

Please note that shipping rates are subject to change at any time. We reserve the right to charge an additional fee in addition to the regularly advertised shipping fee for shipping to remote areas not easily accessible by typical freight carrier means (i.e. islands only accessible by ferry).

FAQ
Q: Is This Ice Machine Compatible With Different Types Of Ice Storage Bins?
A: Yes. The KM‑350MAJ is compatible with Hoshizaki bins and dispensers including B‑300SF, B‑500SF, B‑700SF, and others. A top kit may be required for certain bin models—consult bin specification sheets for proper fit.
Q: What Type Of Ice Does The KM‑350MAJ Produce?
A: It produces individual crescent‑shaped cubes, known for their attractive appearance, efficient cooling, and slower melting rate compared to standard cube ice.
Q: What Is The Warranty Coverage For This Ice Machine?
A: Hoshizaki provides a 3‑year parts and labor warranty on the entire machine, a 5‑year parts and labor warranty on the evaporator, and a 5‑year parts warranty on the compressor and air‑cooled condenser coil. Valid in the U.S., Canada, Puerto Rico, and U.S. Territories.
Q: How Often Should The KM‑350MAJ Be Cleaned?
A: Hoshizaki recommends a full cleaning and sanitizing cycle at least twice per year. In areas with poor water quality or heavy usage, more frequent cleaning may be required. The CleanAssist™ feature simplifies this process with a one‑hour cleaning cycle.
Q: What Are The Operating Limits For This Model?
A: The KM‑350MAJ is designed to operate in ambient temperatures between 45°F and 100°F, water temperatures between 45°F and 90°F, and water pressure between 10–113 PSIG. Voltage range should remain within 104–127V.
Q: Does The KM‑350MAJ Have Built‑In Diagnostics?
A: Yes. The EverCheck™ alert system provides real‑time diagnostics and maintenance alerts, helping operators identify issues early and reduce downtime.
Q: Can This Machine Be Used With A Remote Condenser?
A: No. The KM‑350MAJ is an air‑cooled model. For remote condenser compatibility, see the KM‑520MRJZ or KM‑660MRJZ models.
Q: What Kind Of Water Filtration Is Recommended?
A: It strongly recommends pairing the KM‑350MAJ with a H9320-51 Single 4HC-H water filter system with manifold and cartridge to reduce chlorine, taste, odor, and particulates. Proper filtration extends machine life and ensures crystal‑clear ice.
NOTICE: Do not use with water that is unsafe or of unknown quality without adequate disinfection either before or after the system.

- Connect the cold water supply line (1/2" FPT inlet, minimum 10 psi, maximum 113 psi). Install a shut‑off valve.
- Connect the drain lines (3/4" FPT outlet for icemaker, 3/8" OD condensation drain) with a proper air gap to a floor drain.
- For water‑cooled models, connect condenser water inlet (1/2" FPT) and outlet (3/8" FPT) separately.
- For remote models, connect to the recommended Hoshizaki URC‑5FZ remote condenser unit and follow refrigerant line set instructions.
- Hard‑wire the electrical connection per local code; ensure proper grounding. Use independent power supply of correct capacity.
