The Northair Portable Automatic Ice Maker, model NAIA50NES, is a compact and convenient appliance designed to produce ice cubes for personal use. It features a sleek, stainless steel enclosure and a transparent cover, allowing users to monitor the ice-making process. The unit is equipped with a user-friendly control panel that includes visible functions and a one-touch display setting for ease of operation.
Function Description:
The primary function of this device is to automatically produce ice cubes. Users can select the desired ice cube size (small, medium, or large) via the control panel. The ice maker operates by filling a water reservoir, freezing the water onto evaporator rods, and then pushing the formed ice into an ice basket. An ice sensor detects when the basket is full, at which point the unit automatically stops making ice. The ice-making cycle typically lasts between 6 to 14 minutes, depending on the selected ice cube size and the ambient room temperature. The device includes indicators for "Add Water" and "Ice Full" to alert the user to necessary actions.

- Restart Functionality: After adding water or removing ice, the unit can be restarted by pressing the "Power" button. A 3-minute settling period for the refrigerant is recommended before restarting if the unit has been off.
- Ice Cube Size Selection: Allows users to choose between small, medium, or large ice cubes. Small or medium size is recommended in ambient temperatures below 55°F to prevent ice from sticking together.
Maintenance Features:
- Interior Cleaning: The interior should be cleaned with diluted detergent, warm water, and a soft cloth. The ice basket should be removed for cleaning.
- Exterior Cleaning: The outside of the ice maker should be cleaned regularly with a mild detergent solution and warm water.
- Drying: After cleaning, the interior and exterior should be dried with a soft cloth.
- Water Drainage: When the machine is not in use for a long time, the water drain cap should be opened to completely drain water from the reservoir.
- Water Change: It is recommended to change the water in the water reservoir every 24 hours to ensure hygiene.
- Troubleshooting Guide: The manual provides a comprehensive troubleshooting table for common issues such as "Add Water" indicator on (lack of water), "Ice" indicator on (too much ice), ice cubes sticking together (ice cycle too long or water temperature too low), and ice making cycle normal but no ice made (refrigerant leakage or blocked cooling system pipe).
The appliance emphasizes several critical safety instructions:
- Always read and obey all safety messages in the manual.
- Do not operate with a damaged cord; connect to properly polarized outlets only.
- Avoid running the power cord over carpeting or heat insulators, and keep it away from traffic areas and water.
- The use of an extension cord is not recommended due to overheating risk; if used, it must be No.14 AWG minimum size and rated no less than 1875 watts.
- Unplug the ice maker before cleaning or servicing.
- Exercise caution when used near children.
- Do not use outdoors.
- Maintain at least 4 inches of space between the back and sides of the unit and the wall.
- Only use potable water to make ice cubes.
- Do not clean with flammable fluids.
- Do not tip over.
- Allow the unit to warm up to room temperature for a few hours if brought in from outside in winter.
- The appliance must be earthed.
- DANGER/WARNING: The unit uses flammable refrigerant (R290). Do not use mechanical devices to defrost, puncture refrigerant tubing, or attempt repairs without trained service personnel.
- The ice maker should be installed according to ASHRAE15 safety standards and not in public corridors or hallways.
- Any maintenance requiring component replacement should be done by factory-authorized service personnel.
- DO NOT TOUCH THE EVAPORATOR RODS WHILE THE UNIT IS IN USE OR DURING THE ICE MAKING PROCESS, AS IT MAY CAUSE SEVERE BURNING.
- The appliance must be placed on an even or flat surface to avoid instability.
The Northair Portable Automatic Ice Maker is designed for efficient and safe ice production, provided that all instructions and safety precautions are followed diligently.
