FAQ
Q: What is the difference between the Hoshizaki KM-81BAJ and KM-81BAK?
A: The KM-81BAK increases ice production to 98 lbs/24hrs (up from 78 lbs), switches to environmentally friendly R290 hydrocarbon refrigerant with a smaller charge, and improves energy efficiency (5.6 vs 8.45 kWh per 100 lbs, lower amperage draw). It also adds a stainless steel exterior and front-in/front-out airflow with a removable air filter, though it uses slightly more water per 100 lbs.
Q: What Type of Ice Does the Hoshizaki KM‑81BAJ Produce?
A: The KM‑81BAJ produces individual crescent‑shaped cubes, which are hard, clear, and slow‑melting — ideal for beverages.
Q: What Are the Operating Requirements for Hoshizaki KM‑81BAJ?
A: The KM‑81BAJ requires ambient temperatures between 45–100°F, water temperatures between 45–90°F, and water pressure between 10–113 PSIG.
Q: Is Hoshizaki KM‑81BAJ ADA Compliant?
A: Yes. With its 39" height including legs, the KM‑81BAJ meets ADA compliance standards for accessible installation.
Q: What Warranty Coverage Is Provided for Hoshizaki KM‑81BAJ?
A: Hoshizaki offers a 3‑year parts and labor warranty on the entire machine, 5‑year parts and labor on the evaporator, and 5‑year parts on the compressor and condenser coil.
Q: Can a Filter System Be Added to Hoshizaki KM‑81BAJ?
A: Yes. For enhanced water quality and ice clarity, the KM‑81BAJ can be paired with the H9320‑51 Single 4HC‑H Water Filter System, which provides 21,000‑gallon capacity and 0.5‑micron filtration.
Q: Are Optional Accessories Available for Hoshizaki KM‑81BAJ?
A: Yes. The KM‑81BAJ is compatible with the HS‑5061 Drain Pump Assembly for installations without a gravity drain.
Q: Is There a Larger Capacity Option Than Hoshizaki KM‑81BAJ?
A: Yes. For higher ice production needs, consider the Hoshizaki KM‑116BAJ, which produces up to 125 lbs of ice per 24 hours and offers a larger 53‑lb built‑in storage bin.
NOTICE: Do not use with water that is unsafe or of unknown quality without adequate disinfection either before or after the system.

- Position the Hoshizaki KM‑81BAJ, KM‑116BAJ, and KM-161BAJ in a permanent indoor location with ambient temperature between 45°F–100°F and water temperature between 45°F–90°F.
- Allow at least 12" clearance at the front and 5/8" clearance at the top for service access; provide space at the rear for water and drain connections.
- Level the icemaker front‑to‑rear and side‑to‑side; optional legs (6"–7") can be installed and adjusted for leveling. If mounting flat to a counter, seal the perimeter with approved caulk.
- Electrical connection must be to a dedicated 115V/60Hz/1‑phase circuit with proper breaker or fuse; plug into a grounded 3‑prong outlet. Do not use extension cords.
- Connect the icemaker water supply to the 1/2" FPT inlet using minimum 1/4" ID copper tubing; install a shut‑off valve and drain valve.
- Connect the drain to the 3/4" FPT outlet using minimum 3/4" ID hard pipe; maintain a 2" vertical air gap to the floor drain and slope horizontal runs 1/4" per foot.
- Check refrigerant lines and compressor mounting pads; ensure fan blade turns freely.
- For detailed steps, refer to the installation manual provided in the package or contact a licensed plumber/electrician.
- Follow the recommended maintenance schedule: clean and sanitize the water system and ice bin regularly.
- Inspect and clean the condenser air filter and louvers to maintain airflow.
- Check water supply pressure (10–113 PSIG) and verify proper drainage; clean strainers or filters as needed.
- Inspect refrigerant lines and compressor mounting pads; ensure components are secure.
- Prepare the Hoshizaki KM‑81BAJ, KM‑116BAJ, and KM-161BAJ for long storage by draining the water system and disconnecting power if ambient temperature may drop below freezing.
- Clean exterior panels with mild soap and water; avoid harsh chemicals or abrasives.
- Disconnect power and water supply before servicing internal components to avoid hazards.
- For service or repairs, consult the manual or a certified service representative.
