   Neutral detergent is better if possible.

3. Machine drainage: When the machine is powered on and on standby, remove the silicone plug at the drain outlet and put
   down the drain pipe of the cold water tank, the water in the water storage tank, cold water tank and inner tank can be
   drained. After the drainage is completed, the silicone plug at the drain outlet shall be installed back to its original position.
   4. The machine shell needs to be cleaned when the power is cut off, and it is better to wipe it with a dry cloth.
   5. It is recommended to discard the ice cubes made in the first two rounds.

DURING THE USE OF THE MACHINE, THE ICE MAKER SHOULD BE CLEANED REGULARLY.

1. Repeat the above steps to clean the internal and external of the machine.
2. Especially for the cleaning of the spray pipe on the upper part of the evaporator. When it is found that the compressor and water pump are working normally, but the water in the spray pipe is small or there is no water gushing out,  you can clean each small hole on the spray pipe shown in the figure below to ensure that each small hole is unobstructed.
3. When there is ice on the evaporator, and the adhesion is very firm, never pry hard with objects; You can press briefly the «Ice shedding» button to enter the forced deicing state. The process will takes about 1-4 minutes.

EXPLAIN:
How to drain the water in the water storage tank, cold water tank and inner tank?
The water in the water storage tank is supplied to the cold water tank through the solenoid valve. If you want to drain the water in the water storage tank and the cold water tank, please plug the power and put down the drain pipe on the  cold water tank.
To drain the water in the inner tank, the machine needs to cut off power, and remove the silicone plug at the bottom of the machine. After draining the water in the inner tank, please make sure to put the silicone plug back in place.

MACHINE OPERATION

1. Add water to the machine
   There are two ways to add water.
   One is externally connected water. There is an external water inlet at the lower end of the back of the machine(the external water indicator will be on), another is to add water manually(the external water indicator will be off).
   How to switch the two water-adding modes
   In standby mode, long press «on / off» button for 3 seconds.
   Open the back cover and add drinking water. The water surface should not be higher than the «full» mark. After adding water, cover the rear cover to prevent foreign matters from entering the water storage tank.

2. Ice making operation
   See the schematic diagram for operation keys and display
   • Start the ice-making machine: Plug in the power plug, and the display screen will display the ambient temperature (such as 25 degrees Celsius, it will display «25»). The machine automatically replenishes water to the cold water tank. Press the «on/off» button, the machine starts to make ice (the «Ice making» indicator light will be on), and the display screen shows the time required for ice making (if «16» is displayed, means it will take 16 minutes for the  end of this ice-making process).
   • After the end of each ice-making, it enters into the deicing process, when the ice falls off from the evaporator, the ice guide plate is triggered to turn over once, and the next round ice-making will start. In the process of deicing, if the  ice guide plate is not touched all the time, the machine will automatically stop deicing after 4 minutes and start the next round ice- making.
   Note: Each round ice-making time is about 13-25 minutes. According to the ambient temperature and the added water temperature, each round ice-making time varies from 13-25 minutes.
   Especially for the first time, due to the high water temperature in the water tank, the ice making time will be longer, but it will not exceed 30 minutes.
   • Adjustment of ice thickness: when the thickness of ice cube is not ideal, it can be adjusted by «+ / -» on the control panel during the ice-making process. The number displayed on the screen is to increase or decrease the ice-making time, which is» 0 «by default. Pressing the «+» once will increase the ice- making time by one minute, and the corresponding ice cube will be thicker; pressing the «-» once will reduce the ice-making time by one minute, and the corresponding ice cube will be thinner. When the machine is powered on again, it will return to the default setting of «0».
   Note: the current set time only changes the time of the next and subsequent ice-making cycles.
   The transparency of ice cube is related to the water quality, so pure water or RO water is recommended.
   • When the «Ice Full» indicator light flashes, the ice maker stops working. Removes the ice, the ice maker will start to work again within 3 minutes.
   • When the «Add Water» indicator light flashes, it indicates the cold water tank is short of water, and the machine is in the state of waiting for water replenishment. If the water shortage lasts 2 minutes, the «Add Water» indicator  light will be always on, and the ice maker will stop automatically. Then it needs to add water manually or check whether the external water connection is normal, after adding water, restart the machine. (The machine can not detect  whether the water storage tank is short of water or whether the external water connection is normal.)
   • Turn off the machine: In the process of ice making, press the «on / off» button on the control panel to turn off the machine. Then it will enter the standby mode.
   Forced deicing: In the process of ice making, press the «Ice Shedding» button, and the machine will force deicing. When the ice falls off from the evaporator, the ice guide plate is triggered to turn over once, and the next round ice-making will start. In the process of deicing, if the ice guide plate is not touched all the time, the machine will automatically stop deicing after 4 minutes and start the next round ice-making.

3. Automatic cleaning operation
   Plug machine with the water tank full of water into the power plug. In standby mode, long press the «Timer/Clean» button for 3 seconds to enter the self- cleaning program (the «Clean» indicator light will be on), and the default self-cleaning time is 30 minutes.
   Cancel self-cleaning: It takes about 30 minutes to complete a self-cleaning procedure. When the program is finished, the system will be automatically turned off; during the self-cleaning process, you can also press the « on/off «  button to forcibly exit the self-cleaning program.
   In order to ensure the hygienic requirements, please change the water every 24 hours and clean the water storage tank, cold water tank and inner tank every 3 days.

4. Timing power on/off function operation:
   Timing setting
   Timing setting range: 1-24 hours
   Timing turn off: when the machine is in the ice-making state, set the timing turn off.
   Timing start: when the machine is in standby mode, set the timing to start.

HOW TO SET TIMING

In the mode of ice-making or standby, briefly press the «Timing/Clean» button to enter the timing mode. At this moment, the «Timer» indicator light is on, and the digital display is flashing. Then press the «+» button to adjust the timing time you want, and each time you press it, the time increases by 1 hour, press the «- « means the opposite. In the process of time adjustment, the display number is bouncing, if there is no action after 5 seconds, the timing setting  will take effect automatically and the number will stop bouncing.
The display of «06» in the ice-making state means that the machine will automatically turn off after 6 hours, and «06» in the standby mode means that the machine will automatically start in 6 hours.

HOW TO CANCEL TIMING
After the machine is timed(the «Timer» indicator light is always on), press briefly the «Timing/Clean» button can adjust the timing time. If press briefly the «Timing/Clean» button 2 times, the timing will be canceled.(the «Timer» indicator light will be off)
You can also directly press the «on / off» button forcibly cancel timing, but it will also turn off the machine.
When the machine has a timing setting, the «Timer» indicator light is always on.
Key points for attention when using the machine:

1. Check the inside of the water storage tank and cold water tank to see if there are dirty impurities blocking up, affecting the water flow. Please clean them regularly.
2. The lower the water temperature, the higher the ice production.
3. The lower the ambient temperature of the machine, the greater the ice production.
4. The quality of the water used will affect the service life of the circulating water pump of the machine. It is better to use pure water or distilled water. Some abnormal sound in the working process of the water pump is caused by  impurities in the water, which is a normal phenomenon and does not affect the use of the machine.
5. After the machine stops working, there will be a delay of up to 3 minutes when the machine starts working again.
6. When the machine just starts to make the first 3 rounds of ice cubes, smoothies will appear in the spray pipe, the spraying of the pipe slows down or even stops. It will return to normal after about 10 seconds, it’s a normal  phenomenon caused by super cold water. Subsequent normal ice making will not appear and doesn’t affect the machine.

MAINTENANCE

Note: Maintenance must be performed by qualified professionals.
Warning: Cut off the water and power supply before carrying out maintenance or manual cleaning.

1. External cleaning
   • Clean the environment around the ice maker regularly to keep it clean. Don’t block the vent.
   • The shell should be cleaned with a mild detergent and then wiped clean. If necessary, use commercially available stainless steel cleaners and polishes.
   Note: Stainless steel may rust without proper maintenance.

2. Water inlet filter
   Check the filter element regularly. It is recommended to replace the filter element every 1-3 months.
   Note: Check that the water pressure is lower than the maximum allowable pressure.

3. Interior cleaning
   The inner tank can be directly flushed with a water pipe.
   Note: In order to prevent water leakage, do not directly flush the parts above the water pump or evaporator.

4. Condenser
   • For air-cooled ice makers, the condenser should be cleaned every three weeks. Use a soft brush or a vacuum cleaner with a brush to brush up and down along the fin direction to avoid damaging the heat sink and further affecting the cooling effect.
   • Condenser filters should be cleaned every 2 weeks.
   Note: Be careful when cleaning the condenser as the edges of the fins are sharp.
