This document describes the Nexel Commercial Ice Machine, Model 243319, an air-cooled unit designed for commercial use, featuring an integrated ice dispenser bin.
Function Description:
The Nexel Commercial Ice Machine is a fully automatic appliance that produces and dispenses ice. Once properly installed and connected to a potable water source and power supply, the ice-making process operates automatically. The machine will stop producing ice when the dispenser bin is completely filled. Ice is dispensed by pushing the lower end of the ice outlet forward, which triggers a reducer motor to drive an ice turntable, delivering ice to the outlet channel. The ice then slides into a container due to gravity. Releasing the ice outlet resets the motor, stopping ice delivery. To prevent ice cubes from freezing into large pieces, the machine automatically runs for ten seconds every four hours, regardless of whether ice is required.

Usage Features:
- Installation Requirements: The machine must be installed indoors, not exceeding 6,500 ft. above sea level. It requires sufficient ventilation space: no less than 12" from the front, 8" from the rear, and 6" from each side. The floor must be capable of supporting its weight. A reliably grounded socket with leakage protection is essential, and proper floor drainage should be provided. The ice dispenser should be kept horizontal, adjustable via its feet.
- Power Supply: The power voltage, frequency, and capacity must match the machine's nameplate, with fluctuations not exceeding ±10% of the rated voltage. The ground terminal must be reliably connected.
- Water Supply: Connects to potable water. An inlet water filter (not included, but recommended accessories 243046 Filter Head and 243047 Filter are suggested) is crucial for keeping impurities out of the water. Filters should be replaced every 1-3 months depending on usage. A water valve (not supplied) on the supply line is recommended.
- Drainage: The drain pipe must be installed to ensure continuous downward flow, with no point higher than the machine's drain port or any previous point. The inside diameter of the drain pipe should be >15.8 mm (5/8"), with a fall of >3cm per meter.
- Operation Modes:
- Self-check: Initiates upon power-on, indicated by "ini" on the LED display.
- Preparing: Counts seconds positively on the LED.
- Ice Making: Counts seconds positively until water reaches 0°C, then counts down to 0s. The water pump starts, and water flows over the evaporator to form ice cubes.
- Ice Harvest (Drop): After ice making, the water pump turns off, and the defrost valve activates, allowing hot gas to release ice into the bin. "HARV." is displayed. Users are warned to keep hands away from the bin during this process to prevent injury or contamination.
- Full Bin Auto-Stop: The machine automatically stops when the ice bin is filled and the sliding board cannot reset. It restarts within seconds once ice is removed.
- Shutdown: The ice maker stops when the "on/off" button is pressed during operation.
- Ice Thickness Adjustment: During ice making, the thickness can be adjusted by pressing the "Ice cube" button for 3 seconds, then using the "+" or "-" buttons. Each click extends or shortens the ice making time by 1.5 minutes.
- Voice Function: (For models with this feature) Provides voice prompts for operations.
- Safety Features:
- Hazardous Voltage Warnings: Labels indicate risk of electric shock; disconnect power before servicing.
- Fire Hazard Warnings: Labels indicate use of flammable foaming agent "Cyclopentane" and refrigerant "R290"; risk of fire.
- Rotating Components Warning: Labels indicate rotating parts inside; do not operate with panels open; disconnect power before maintenance.
- Automatic Shutdown: If the machine fails to detect ice falling off in three cycles, or if ambient temperature is too high, it will shut down for safety. Water-cooled models will stop if water supply abnormality is detected.
- Error Codes: The LED display shows specific codes (e.g., E03 for ice harvest overtime, E04 for high system temperature, E05 for water shortage) to indicate faults and trigger protective shutdowns.
Maintenance Features:
- General Maintenance: Must be performed by qualified professional personnel. Always cut off water and power supply before maintenance or cleaning.
- Exterior Cleaning: Frequently clean the area around the machine and wipe the outer enclosure with a mild detergent. Use commercial stainless steel cleaners if needed.
- Inlet Water Filter: Inspect regularly and replace the filter element every 1-3 months.
- Interior Cleaning: The inside of the ice storage bin can be washed directly with water pipes. Avoid flushing parts above the water pump or evaporator directly if water pressure is too high.
- Condenser Cleaning (Air-cooled models): Clean every three weeks using a soft brush or vacuum cleaner, brushing along the fin direction to avoid damage. The condenser filter should be cleaned every two weeks. Caution is advised due to sharp fin edges.
- Water Pipe Cleaning: Clean regularly to ensure food safety.
- Wintering: Turn off water and power supply, then drain residual water from the trough, inlet pipe, and drain pipe.
- Cleaning Function (Automated):
- Empty the ice bin.
- Clean and sterilize the bin, ice sliding board, water distribution pipe, water supply pipe, and water pump, then rinse thoroughly.
- Press and hold the "clean" button for 3 seconds to enter the cleaning process.
- Manually add cleaning agents and disinfectants to the water trough.
- The machine performs an auto-clean for about 15 minutes, including spray cleaning of the evaporator.
- After cleaning, the machine enters a rinsing process for about 5 minutes (5 cycles).
- The machine returns to ice making.
- Discard the first 5 batches of ice after cleaning to ensure no cleaner residue remains.
- Long-Term Storage: If not in use for a long time, disconnect power, remove all ice, wipe water stains, clean the outer surface, and store in a dry, ventilated place. If stored for more than three months, reset the internal controller before reuse. The machine should be energized and run for 2-4 hours every 2 months if not in use for a long time.
