- Position the Hoshizaki KM‑350/420/520/660 modular cuber in a permanent indoor location with ambient temperature between 45°F–100°F and water temperature between 45°F–90°F.
- Allow proper clearance: 6" at rear, sides, and top for air‑cooled and water‑cooled models; 12" clearance at right side for certain air‑cooled units. Remote condenser units require 24" clearance front and rear.
- Unpack the ice storage bin or dispenser unit; attach adjustable legs if applicable and place in location. Level the bin or dispenser front‑to‑rear and side‑to‑side.
- Place the icemaker on top of the bin or dispenser; secure using mounting brackets and bolts provided. Ensure bin opening matches icemaker drop zone.
- Electrical connection must be hard‑wired to a dedicated 115V/60Hz/1‑phase circuit with proper breaker size (15–20A depending on model). Connect black wire to HOT, white to neutral, and ground to ground screw. Unit must be properly grounded.
- Connect potable water supply to the 1/2" FPT inlet using minimum 1/4" ID copper tubing; install shut‑off valve and drain valve.
- Connect icemaker drain to 3/4" FPT outlet using minimum 3/4" ID hard pipe; maintain 2" vertical air gap to floor drain and slope horizontal runs 1/4" per foot.
- For water‑cooled models, connect condenser water inlet (1/2" FPT) and outlet (3/8" FPT) separately; install shut‑off and drain valves as required.
- For remote models, connect refrigerant line set to approved Hoshizaki remote condenser (URC‑5FZ); follow line set sizing, refrigerant charge, and electrical connection instructions.
- Check refrigerant lines and compressor mounting pads; ensure fan blade turns freely.
- Open water supply, purge air from lines, and check all connections for leaks.
- For detailed steps, refer to the Hoshizaki KM‑350/420/520/660 installation manual or contact a licensed plumber/electrician.
- Inspect air filters bi‑weekly; wash with warm water and neutral cleaner if dirty.
- Check external water filters monthly; replace if pressure drops. Wipe down exterior panels with soft cloth and neutral cleaner.
- Clean and sanitize icemaker and bin at least yearly using Hoshizaki “Scale Away” cleaner followed by sanitizing solution.
- Inspect condenser fins and cabinet louvers yearly; clean with brush or vacuum. More frequent cleaning may be required depending on environment.
- Check water hoses and inlet screens yearly; clean or replace as needed.
- Verify bin control operation during startup; ensure proper shut‑down when actuator paddle is pressed.
- Disconnect power before servicing internal components; lockout/tagout to prevent accidental energizing.
- For service or repairs, consult the manual or a certified Hoshizaki service representative.
