This ice machine is designed for commercial use in indoor, ambient-controlled environments. Important: Upon delivery, keep the machine upright for at least 24 hours before startup to allow the refrigerant to settle. Installation, repair, and maintenance must be performed by professional and qualified personnel. Ensure the machine is placed on a level floor capable of supporting its weight and that it is properly grounded with leakage protection.
Installation
Proper installation is critical for performance and safety.
- Clearance: Maintain at least 12 inches of space at the front, 6 inches at the sides, and 8 inches at the rear for ventilation.
- Environment: Ambient temperature should be between 40-90°F. Avoid direct sunlight and heat sources.
- Water Supply: Use potable water with pressure between 18.75 psi and 80 psi. Do not connect to hot water.
- Drainage: Ensure proper floor drainage is available. The drain pipe should have a downward slope of at least 1 inch per 3 feet.
Operation
The machine operates automatically. Once the storage bin is full, the sensor will stop production. When ice is removed, production resumes.
- Startup: Turn on the power switch. The machine will perform a self-check and begin the ice-making cycle.
- Control Panel: Use the panel to monitor status (Init, Prep, Make, Harv, Inlet, Fault).
- Thickness Adjustment: During the ice-making process, press the "-" button for 3 seconds, then use "+" or "-" to adjust thickness. Each click extends or shortens the cycle by 1.5 minutes.
Cleaning and Sanitizing
Regular cleaning is required to maintain hygiene and warranty coverage.
- Clean Function: Hold the "clean" button for 3 seconds to enter the cleaning mode. Follow the prompts to add cleaning or sanitizing solutions to the water trough.
- Manual Cleaning: Periodically remove the water curtain, spray pipe, and pump to scrub them with a cleaning solution.
- Chemicals: All cleaning and sanitizing chemicals must be nickel-safe.
- Frequency: Clean every other month, or monthly in high-yeast environments.
Maintenance
- Exterior: Clean with mild detergent. Keep vents clear.
- Condenser: Clean every three weeks using a soft brush or vacuum.
- Water Filter: Inspect regularly and replace the cartridge every 3 to 6 months.
- Winterizing: If not in use for a long time, turn off water and power, and drain all residual water from the trough, inlet, and drain pipes.

Common problems
Machine not working
Ensure the power switch is turned on and the plug is secure.
High temperature fault (E04)
Clean the condenser and ensure proper ventilation around the machine.
Ice cubes too thin or incomplete
Check ice thickness settings, ensure water pressure is between 1.3 bar and 5.5 bar, and check if the water filter needs replacement.
Too much noise
Ensure the machine is placed on a level foundation and the legs are adjusted correctly.
Before use
- Keep the machine upright for at least 24 hours after delivery.
- Ensure the floor is level and can support the machine's weight.
- Verify water pressure is between 18.75 psi and 80 psi.
- Confirm the power supply matches the machine nameplate.
- Ensure the machine is properly grounded with leakage protection.
- Remove all packaging tape and items from the ice bin.
Specs in practice
