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.

Special Case Shipping Rates
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). If your order falls into this category, you will be notified upon receipt of your order, and have the option to complete the purchase with additional fee or to cancel the order.

FAQ
Q: What Type of Ice Does the KM‑901MAJ Produce?
A: The KM‑901MAJ produces individual crescent‑shaped cubes, valued for their clarity, efficient cooling, and slower melt rate compared to standard cubes.
Q: Which Bins or Dispensers Are Compatible With the KM‑901MAJ?
A: The KM‑901MAJ is compatible with Hoshizaki bins including B‑500SF, B‑700SF, B‑900SF, B‑1150SS, and larger capacity bins like B‑1300SS and B‑1650SS. A top kit may be required for certain bin models.
Q: Can Filtration Be Added to the KM‑901MAJ?
A: Yes. Compatible filtration systems include the H9320‑52 Double 4HC‑H Filter System and related cartridges, which improve water quality, reduce scale buildup, and extend machine life.
Q: What Is the Warranty Coverage for the KM‑901MAJ?
A: Hoshizaki provides a 3‑year parts and labor warranty on the entire KM‑901MAJ, plus 5 years on the evaporator and compressor. Warranty is valid in the U.S., Canada, Puerto Rico, and U.S. Territories.
Q: How Does the KM‑901MAJ Differ From Other Models in the Series?
A: The KM‑901MAJ is the air‑cooled version producing up to 905 lbs/day. The KM‑901MWJ is water‑cooled with higher efficiency (950 lbs/day), while the KM‑901MRJZ and KM‑901MRJZ3 are remote air‑cooled models designed for installations requiring reduced heat and noise, with single‑phase and three‑phase options.
NOTICE: Do not use with water that is unsafe or of unknown quality without adequate disinfection either before or after the system.

- Ensure installation is performed by a qualified service technician; follow all national, state, and local codes.
- Locate the KM‑901MAJ indoors on a firm, level foundation; ambient temperature must remain between 45°F–100°F (7℃–38℃).
- Allow at least 12" (30 cm) clearance at rear, sides, and top for proper air circulation and service access.
- Position the ice storage bin or dispenser unit; attach adjustable legs and level in both directions.
- Remove panels (front, top, right side, insulation) to prevent damage during installation.
- Connect icemaker water inlet to 1/2" FPT fitting; connect drain outlet to 3/4" FPT fitting using appropriate plumbing.
- Install condensation drain outlet (3/8" O.D. tube) per diagram; ensure proper slope for drainage.
- Provide independent electrical supply: 208–230V/60Hz/single phase; maximum fuse size 20A; icemaker must be grounded.
- Connect pump (120V, 1.2 FLA) and fan motor (115V, 1.0A, 1/15 HP each) per wiring diagram; verify compressor rating (9.3 RLA, 46 LRA).
- Check refrigerant charge: R‑404A, 3 lb. 4.9 oz.; design pressure HI‑467 PSI, LO‑230 PSI.
- Inspect refrigerant lines to ensure they do not rub or touch other surfaces; verify fan blades turn freely.
- Turn on water supply, check for leaks, and correct before startup.
- Restore electrical power; move control switch to “ON” and verify icemaker operation.
- For detailed steps, refer to the Hoshizaki KM‑901MAJ installation manual or contact a certified Hoshizaki service representative.
- Follow a regular maintenance schedule; clean and sanitize icemaker at least twice per year.
- Inspect condenser coil and air filters; clean to maintain efficiency.
- Check water supply and drain connections regularly; reseal or tighten fittings as needed.
- Verify ice bin control operation; adjust if ice production does not stop when bin is full.
- Disconnect power and water supply before servicing internal components to avoid hazards.
- Prepare icemaker for non‑use by draining water lines and disconnecting power if ambient temperature may drop below freezing.
- For service or repairs, consult the manual or a certified service representative.
