- Do not run the power cord over carpeting or other heat insulators. Do not cover the cord. Keep cord away from traffic areas and do not submerge in water.
- Avoid extension cords; they may overheat and pose a fire risk. If an extension cord is necessary, use a minimum 14AWG size rated for at least 1875 watts.
- Unplug the ice maker before cleaning or servicing.
- Exercise caution and supervision when the appliance is used near children.
- Do not use the ice maker outdoors. Place it away from direct sunlight. Ensure at least 4 inches of space between the back of the unit and the wall, and 4 inches on each side.
- Do not use liquids other than water to make ice cubes.
- Do not clean the ice maker with flammable fluids, as fumes can create a fire hazard or explosion.
- Do not tip over the unit.
- If the ice maker is brought in from outside in winter, allow it to warm up to room temperature for a few hours before plugging it in.
- WARNING: This appliance must be earthed.

Unpacking Your Ice Maker
- Remove exterior and interior packaging. Check for ice basket and ice scoop. Contact customer service if parts are missing.
- Remove tapes securing the ice shovel, ice basket, and ice scoop. Clean the tank and ice basket.
- Place the ice maker on a level, flat countertop away from direct sunlight and heat sources (e.g., stove, furnace, radiator). Ensure at least a 4-inch gap between the back and sides of the unit and the wall.
- Allow one hour for the refrigerant fluid to settle before plugging in the ice maker.
- Ensure the appliance is positioned so the plug is accessible.
WARNING: Fill with potable water only. Only use drinking water.
Connecting Your Ice Maker
? DANGER
* Improper use of the grounded plug can result in electrical shock. If the power cord is damaged, please call customer service.
- This unit must be properly grounded for your safety. The power cord has a three-prong plug that mates with standard three-prong wall outlets to minimize electric shock possibility.
- Plug your appliance into an exclusive, properly installed, grounded wall outlet. Never cut or remove the third (ground) prong from the power cord. Direct any questions concerning power and/or grounding to a certified electrician.
- This appliance requires a standard 110-120volt, 60Hz electrical outlet with a three-prong ground.
Cleaning and Maintaining Your Ice Maker
It is strongly recommended to clean the ice maker thoroughly before use.
- Take out the ice basket.
- Clean the interior with diluted detergent, warm water, and a soft cloth.
- Rinse the inside parts with water and drain by unplugging the drain cap on the front bottom side.
- Clean the outside of the ice maker regularly with a mild detergent solution and warm water.
- Dry the interior and exterior with a clean, soft cloth.
- When the machine is not to be used for a long time, drain all water completely and dry the interior.
Using Your Ice Maker
- Open the cover, remove the ice basket, and pour water into the tank. Keep water level below the maximum water level mark.
- Press the [ON/OFF button] on the control panel to begin the ice-making cycle.
- Select the ice cube size by pressing the [Select button]. If the room temperature is lower than 60°F (15.5°C), it is recommended to select small ice cubes to avoid sticking.
- The ice-making cycle lasts approximately 6 to 13 minutes, depending on the selected ice cube size and room temperature. The recommended room temperature is 50°F to 105°F (10°C to 40.5°C).
- If the water pump cannot inject water, the ice maker will stop automatically, and the [Add Water indicator] will illuminate. Press the [ON/OFF button], fill water up to the maximum water level mark, and press the [ON/OFF button] again to restart. Allow the refrigerant liquid inside the compressor at least 3 minutes to settle before restarting.
- The ice maker stops when the ice basket is full, and the [Ice Full indicator] will illuminate.
- Warning: Direct sunlight or sunlight reflection may cause infrared sensor malfunction. If the unit does not stop even when ice cubes obstruct the sensor, move the unit to a location without direct sunlight.
- Change water in the water reservoir every 24 hours to ensure reasonable hygiene. If the unit isn't to be used, drain all the water and dry the tank.
Troubleshooting
| PROBLEM | POSSIBLE CAUSE | SOLUTION |
|---|---|---|
| "Add Water" indicator is on. | Lack of Water. | Stop the ice maker, fill water, and press the [Power button] again to restart the unit. |
| "Ice Full" indicator is on. | Ice is full in basket. | Remove ice from the ice basket. Continuous press the [Select button] for 5 seconds; the unit can make ice for 10 cycles even if the "Ice Full" indicator is on. |
| Ice cubes stick together. | The ice-making cycle is too long. | Stop the ice maker, and restart it when the ice blocks melt. Select the small size ice cube option. |
| Water temperature in inner tank is too low. | Replace the water. Recommended water temperature is 40°F-90°F (4.5°C-32°C). | |
| Ice making cycle is normal but no ice formed. | Room temperature or water temperature in inner tank is too high. | The room temperature should be 50°F-105°F (10°C-40.5°C), water temperature should be 40°F-90°F (4.5°C-32°C). |
| Refrigerant in cooling system leaks. | Verified by a qualified technician. | |
| Pipe in the cooling system is blocked. | Verified by a qualified technician. |
