Hoshizaki EcO3Ice guide

Installation

  • Mount the EcO3Ice unit on the wall near your ice machine (within about 3 feet).
  • Connect the water line into the “IN” side of the unit, then connect the outlet line to the ice machine.
  • Make sure all tubing connections are tight and leak‑free.
  • Plug the unit into a power outlet; the green light will show it’s on.
  • Only use clean, cold water for the system.
  • For detailed steps, refer to the installation manual provided in the package or contact a licensed technician.


Maintenance

  • Check the LED lights on the unit:
    • Green = working normally
    • Yellow = cartridge needs replacing soon
    • Red = replace cartridge now
  • Replace the cartridge every 6–24 months depending on ice machine size and usage (smaller machines last longer, larger machines need more frequent changes).
  • To replace: unplug the unit, close the water valve, twist out the old cartridge, insert the new one, then turn water and power back on.
  • Wipe the outside with a soft cloth; do not spray water directly on the unit.
  • For service or repairs, consult the manual or a licensed technician.
