OPERATING PROCEDURES & MAINTENANCE

UNPACKING YOUR ICE MAKER

  1. Remove the exterior and interior packaging. Check that ice basket and ice scoop is included. If any parts are missing, please contact customer service.
  2. Clean the interior with lukewarm water and a soft cloth. Take out the ice basket and clean it.
  3. Find a location for your ice maker that is protected from direct sunlight and other sources of heat (i.e.: stove, furnace, radiator). Place the ice maker on a level surface. Make sure that there is at least 6 inches of space between the back and sides of your ice maker and the wall.
  4. Allow one hour for the refrigerant fluid to settle before plugging ice maker in.
  5. 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.

  1. 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.
  2. 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.
  3. This appliance requires a standard 110-120volt, 60Hz electrical outlet with three-prong ground.

CLEANING AND MAINTAINING YOUR ICE MAKER

Before using your ice maker, it is strongly recommended to clean it thoroughly.

  1. Take out the ice basket.
  2. Clean the interior with diluted detergent, warm water and a soft cloth.
  3. Then use the water to rinse the inside parts, and drain out the water from the draining port by unplugging the Water drainage cap on the bottom.
  4. The outside of the ice maker should be cleaned regularly with a mild detergent solution and warm water.
  5. Dry the interior and exterior with a soft cloth.
  6. 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, we also suggest you should clean your unit. Especially the water separator pipe and the water filters, you must clean them periodically.

  1. If the water separator pipe is blocked and there is no water flowing down when you listen the compressor and the water pump inside are still working, please turn off the unit first and disassemble this pipe down, and clean it. Clean each hole on the pipe wall displayed in the following picture. After cleaning, install back the water separator pipe and be sure the right terminal of the pipe connects to the silicone pipe well and as original.

A textual description of the diagram showing the water separator pipe:

The diagram shows the interior of the ice maker, focusing on the "Water Separator Pipe" which has multiple "Hole"s. The "Evaporator" is also visible.

  1. For both of the water tank and the big water reservoir, clean them with diluted detergent, warm water and a soft cloth. Then use the water to rinse the inside, and drain out the water from the draining port by unplugging the Water drainage cap on the bottom. It will help you keep the unit and ice-cube hygienicly, and also make the unit work normally.
  2. When cleaning, if you find that the ice cube left on the evaporator and cannot be taken out easily, you can turn on the unit to let the unit enter the ice making process, then press the “ON/OFF” button for more than 5 seconds to let the unit start ice harvest process to melt the ice cube. This will help you remove the hard ice cube.

How to drain out the water from the internal tank and big water reservoir completely

Because the water in the big water reservoir is stopped from draining by the water valve, if you want to drain away all the water, please plug on the unit and but don't start the unit, then remove the Water drainage cap at the bottom. Wait some minutes, all of the water will flow out.

USING YOUR ICE MAKER

Operation panel and display area

A textual description of the operation panel and display area:

The operation panel shows an "OPERATION AREA" with buttons TIMER/CLEAN (A) and ON/OFF (B). The "DISPLAY AREA" (C) shows various symbols and indicators numbered 1 through 8. Another "OPERATION AREA" shows adjustment buttons + and -.

  1. Remove the cover of the water reservoir and pour potable water into the water reservoir. And be sure to keep water level below the max. level with the FULL mark displayed.
  2. How to turn on the unit: Plug the unit. The electric power symbol <⚡> will start to flash, and the present ambient temperature will display at the top left corner of the displaying window (e.g., "80°F" means 80 Fahrenheit ambient). Again press the “ON/OFF” button ▶️ to start the unit. First, the water will flow into the water tank to the standard water level, then the compressor starts to run to make ice-cube. At the same time, the power symbol <⚡> will change to display always, and the ice-cube symbol <?> will be rotating. The ambient temperature display will disappear. After some minutes of ice-making duration, a flashing digit will display in the ambient temperature displaying area (e.g., the flashing digit "10M" ⏳ means that it will take 10 minutes to complete this ice-making process).
  3. When ice maker harvests, the symbol <⚡❄️> flashes. Water flows from the top water reservoir to the bottom water tank through the solenoid valve. The symbol <?> will be on. When the water in the bottom water tank is full, the symbol <?> will be off, then the next ice making cycle starts again. When there is no water in the water reservoir, the symbol <?❌> will keep on. Turn off the unit and fill water again, then restart the unit to make ice cube. Or fill water directly and wait 20 mins, the unit will restart.

Remark: The ice making cycle lasts about 13 to 25 minutes, depending on the ambient temperature. For the first time, according to the initial water temperature, ice-making time will be a little longer. In extreme hot room temperatures, ice-making time may vary a lot, but it will not exceed 35 minutes.

If you think the ice cube is not thick enough, during ice making, press the <+> ➕ and <-> ➖ to set the ice making lead time. Press one time and the ice making cycle will increase or reduce by one minute, 6 minutes most. This can only start from the new cycle.

  1. When the Ice Full symbol <?⬆️> is on, the unit will stop. Take out the ice cube inside, and the unit will start working again.
  2. If you press the button <ON/OFF> ▶️/⏹️ for more than 5 seconds, when the ice maker is working, the unit will start harvest. Press button <ON/OFF> ▶️/⏹️, the unit will turn off.
  3. Timer setting: Unit on timer setting: When the unit is working, timer setting the unit off. Timer setting: When the unit is off, timer the unit on. Press the <TIMER> ⏰ button, the display will show <1H> ⏰, and then press <+> ➕ and <-> ➖ to set the time. During the setting, the H is flashing; after 5s, the H will keep on, and the unit will be in your Timer setting.
  4. Water Drain: Take off the Water draining cap from the bottom of the unit, then drain the water inside. It is better to exchange water every 24 hours and clean the unit every 3 days.

Automatic self-cleaning program

Start the self-cleaning program: Plug on the unit, press “TIMER/CLEAN” ⏰⚙️ button on the control panel for more than 5 seconds, to enter the self-Cleaning program. It needs 20 minutes. The symbol ⚙️ rotates on display screens, time count down area displays 20M ⏳.

Cancel the self-cleaning program: It takes about 20 minutes to complete one self-cleaning program. When the program is over, the system will be in off-state automatically. You can also press the “ON/OFF” ▶️/⏹️ button on the control panel to cancel the self-cleaning program by force.
