Important Safety Instructions
Your safety and the safety of others are very important. We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety messages.
This is the safety alert symbol: ⚠️
All safety messages will follow the safety alert symbol and the word "DANGER" or "WARNING".
DANGER: You can be killed or seriously injured if you don't immediately follow instructions.
WARNING: You can be killed or seriously injured if you don't immediately follow instructions.
All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you what can happen if the instructions are not followed.
When using electrical appliances, basic safety precautions should be followed to reduce the risk of fire, electric shock, and injury to persons or property. Read all instructions before using any appliance.
- Do not operate this, or any other appliance with a damaged cord. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similarly qualified person in order to avoid a hazard.
- This ice-maker must be positioned so that the plug is accessible. Connect to properly polarized outlets only. No other appliance should be plugged into the same outlet. Be sure that the plug is fully inserted into the receptacle.
- 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.
- We do not recommend the use of an extension cord, as it may overheat and become a risk of fire. If you must use an extension cord, use No.14AWG minimum size and rated no less than 1875 watts.
- Unplug the ice maker before cleaning or making any repairs or servicing.
- Exercise caution and use reasonable supervision when appliance is used near children.
- Do not use your ice-maker outdoors. Place the ice-maker away from direct sunlight and make sure that there is at least 4 inches of space between the back of your unit and wall. Keep a minimum distance of 4 inches on each side of your unit free.
- Do not use other liquid to make the ice-cube other than water.
- Do not clean your ice maker with flammable fluids. The fumes can create a fire hazard or explosion.
- Do not tip over.
- If the ice maker is brought in from outside in wintertime, give it a few hours to warm up to room temperature before plugging it in.
WARNING: This appliance must be earthed.

Unpacking Your Ice Maker
- Remove the exterior and interior packaging. Check if the ice basket and ice scoop are inside. If any parts are missing, please contact customer service.
- Remove the tapes for fixing the ice shovel, ice basket & ice scoop. Clean the tank & ice basket.
- Place the ice maker on a level & flat counter top away from direct sunlight and other sources of heat (i.e.: stove, furnace, radiator). Ensure there is at least 4 inches gap between the back & LH/RH sides and the wall.
- Allow one hour for the refrigerant fluid to settle before plugging the ice maker in.
- The appliance must be positioned so that 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 the risk of electrical shock. If the power cord is damaged, please call customer service.
- This unit should be properly grounded for your safety. The power cord of this appliance is equipped with a three-prong plug which mates with standard three-prong wall outlets to minimize the possibility of electric shock.
- Plug your appliance into an exclusive, properly installed, grounded wall outlet. Do not under any circumstances, cut or remove the third (ground) prong from the power cord. Any questions concerning power and/or grounding should be directed toward a certified electrician.
- This appliance requires a standard 110-120volt, 60Hz electrical outlet with a three-prong ground.
Cleaning and Maintaining Your Ice Maker
Before using your ice maker, it is strongly recommended to clean it thoroughly.
- 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 out the water by unplugging the drain cap on the front bottom side.
- The outside of the ice maker should be cleaned 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 water completely & 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 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, it is recommended to select small ice cubes to avoid ice sticking together.
- The ice making cycle lasts approximately 6 to 13 minutes, depending on the selection of ice cube size and the room temperature. The recommended room temperature is 50°F to 105°F.
- If the water pump cannot inject water, the ice maker will stop automatically, and the "Add Water" indicator will be on. Press the "ON/OFF" button, fill water up to the max. water level mark, and press the "ON/OFF" button again to turn on the unit. 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 be on. Warning: Direct sunlight or sunlight reflection may cause infrared sensor malfunction. If the unit doesn't stop even when ice cubes obstruct the sensor, move the unit where there is no sunlight.
- Change water in the water reservoir every 24 hours to ensure a reasonable hygiene level. 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 "Power" button again to restart the unit. |
| "Ice Full" indicator is on. | Ice is full in basket. | Remove ice from ice basket. Continuous press "Select" button for 5 seconds; the unit could make ice 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 selection. |
| Ice making cycle is normal but no ice formed. | Water temperature in inner tank is too low. | Replace the water. Temperature of water recommended at 40°F-90°F. |
| Room temperature or water temperature in inner tank is too high. | The room temperature should be 50°F-105°F, water temperature should be 40°F-90°F. | |
