PREPARING YOUR ICE MAKER FOR USE
IMPORTANT SAFETY TIPS
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.
- 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.14 AWG 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 the 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 6 inches of space between the back of your unit and the wall. Keep a minimum distance of 6 inches on each side of your unit free.
- Do not use any liquid other than water to make ice cubes.
- 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.

OPERATING PROCEDURES & MAINTENANCE
UNPACKING YOUR ICE MAKER
- Remove the exterior and interior packaging. Check that the ice basket and ice scoop are included. If any parts are missing, please contact customer service.
- Clean the interior with lukewarm water and a soft cloth. Take out the ice basket and clean it.
- Find a location for your ice maker that is protected from direct sunlight and other sources of heat (e.g., stove, furnace, radiator). Place the ice maker on a level surface. Ensure there is at least 6 inches of space between the back and sides of your ice maker 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.
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 110-120 volt, 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.
- Use water to rinse the inside parts, and drain out the water from the draining port by unplugging the drain cap on the back.
- 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 soft cloth.
- When the machine is not in use for a long time, open the water drain cap to drain water completely out from the water reservoir.
After using your ice maker for a long time, it is also suggested to clean your unit. Pay special attention to the water separator pipe and the water filters; you must clean them periodically.
Cleaning the Water Separator Pipe: If the water separator pipe is blocked and there is no water flowing down when you listen to the compressor and water pump working, turn off the unit, disassemble the pipe, and clean it. Clean each hole on the pipe wall. After cleaning, install the pipe back, ensuring the correct terminal connects to the silicone pipe.
Diagram Description: An illustration shows the water separator pipe with multiple holes and the evaporator component.
Cleaning Water Tank and Reservoir: For both the water tank and the large water reservoir, clean them with diluted detergent, warm water, and a soft cloth. Rinse with water and drain from the port at the back. This keeps the unit and ice cubes hygienic and ensures normal operation.
Removing Stubborn Ice Cubes: If ice cubes are stuck on the evaporator and cannot be removed easily, turn on the unit to start the ice-making process, then press the "ON/OFF" button for more than 5 seconds to initiate the ice harvest process, which melts the ice cubes.
How to Drain Water from the Internal Tank and Big Water Reservoir Completely
Because water in the big water reservoir is held by a valve at the drain port, to drain all water: plug in the unit (do not start it), then remove the drain port cap at the back. Wait a few minutes for all water to flow out.
USING YOUR ICE MAKER
Operation Panel and Display Area
The operation panel includes buttons for Timer, ON/OFF, and controls for adjusting ice making time (+/-). The display area shows various status indicators.
Diagram Description: An illustration shows the layout of the operation panel and display area, including buttons and symbols.
- Remove the water reservoir cover and pour potable water into the reservoir. Ensure the water level is below the max. level indicated by the "FULL" mark. Replace the cover immediately to prevent foreign matter from entering.
Diagram Description: An illustration shows the water reservoir cover and the "FULL" water level indicator.
Warning: Do not pour water into the internal water tank located underneath the ice basket, as it is not large enough and will affect ice-making performance.
- When you plug in the unit, the power symbol ⚡ will flash. Press the ON/OFF button to start making ice cubes; the ice-making symbol ❄️ will run continuously. The top-left corner of the display shows the ambient temperature (e.g., 80°F). After a few minutes, this area will show a flashing number indicating the ice-making countdown (e.g., 10M means 10 minutes until completion).
- When the ice maker is in harvest mode, the ❄️ symbol flashes. Water flows from the top reservoir to the bottom water tank via a solenoid valve. The symbol ? will be on. When the bottom water tank is full, the ? symbol turns off, and the next ice-making cycle begins. If there is no water in the water reservoir, the ? symbol will remain on. Turn off the unit, fill with water, and restart. Alternatively, fill water directly and wait 20 minutes for the unit to restart.
Remark: The ice-making cycle lasts approximately 13 to 25 minutes, depending on ambient temperature. The first cycle may be longer due to initial water temperature. In very hot room temperatures, ice-making time may vary but will not exceed 35 minutes.
If the ice cubes are not thick enough, during ice making, press the <+> and <-> buttons to adjust the ice-making lead time. Each press adds or reduces one minute, up to a maximum of 6 minutes. This adjustment can only start from a new cycle.
- When the ❄️ (Ice Full) symbol is on, the unit will stop. Remove the ice cubes inside, and the unit will resume working.
- Pressing the ON/OFF button for more than 5 seconds while the ice maker is working will initiate the harvest cycle. Pressing the ON/OFF button normally will turn the unit off.
- Timer Setting: To set the timer: When the unit is on, you can set it to turn off. When the unit is off, you can set it to turn on. Press the TIMER button; the display will show <1H>. Then press <+> and <-> to set the time. During setting, 'H' flashes; after 5 seconds, 'H' stays on, and the unit will operate on your timer setting.
- Water Drain: Take off the drain plug cap on the back of the unit, remove the silicon plug, and drain the water inside. It is recommended to exchange water every 24 hours and clean the unit every 3 days.
Diagram Description: An illustration shows the drain plug and silicon plug on the back of the unit, with "OPEN" and "CLOSE" indicators.
Warnings
- A. Make sure the water tank, water filter, and water separator pipe are not blocked; clean them.
- B. Water temperature affects ice-making capacity. Lower temperatures produce more ice cubes.
- C. Cooler ambient temperatures produce more ice cubes.
- D. Always use good quality water to ensure the pump works well. Poor quality water may cause pump noise but does not affect unit operation.
- E. The compressor restarts 3 minutes later if you turn off the unit.
