Installation Steps

1. Check if the ice machine is in good condition and the accessories are complete; check the machine model and the machine nameplate.

2. Clean the ice storage bin and the food area inside with a sponge soaked in warm water and soda. Then wash and dry it with potable water.

3. Place the ice machine in the operation area; ensure that the machine is placed on a leveled floor. So as to ensure the water flows evenly on the evaporator.

4. The compressor chamber is located at the back. The compressor and condenser are installed in it. For air cooled unit, it requires good ventilation. Therefore, the front and rear of the ice maker must have ventilation space of more than 20-30 cm.

5. The bottom of the ice machine is equipped with adjustable legs for level adjustment and floor cleaning.

6. Connect the machine’s inlet water filter and water pipe referring to the schematic diagram of installation; if the installation site is already equipped with a drinking water system, the water filter may not be installed.
   Note: the filter flow direction should be correctly installed as per the direction marker on the filter head cover or the filter body
   Note: This machine is equipped with an inlet water filter. The filter will have impurities from the water accumulated as the machine is running. Generally, it needs to be replaced every month to every 3 months.

7. Connect the machine to the water supply using the 3/4″ inlet pipe supplied with the machine. It is recommended to install a water valve (not supplied with this machine) on the water supply line.

8. Connect the drain pipe to the drain connection. In order to meet a good draining, it is recommended that the drain pipe should have a difference of level more than 3cm per meter; and confirm that the drain pipe is not blocked. It is recommended that the drain pipe be connected to an open drainage port.

9. Any joint in the drain pipe must not be higher than the machine drainage port; any joint in the drain pipe cannot be higher than the previous joint.

10. Confirm the power requirements stated in the machine nameplate; ensure that the power supply meets the requirements.

11. A circuit breaker or switch with leakage protector and reliably grounding is required.

12. Tum off the switch on the power line and connect the machine to the power source.

Startup and Operation

1. Before you start up the machine, please check and confirm:

• That the packaging tape inside the ice machine has been removed:
• The accessories or items in the ice bin have been taken out:
• The ice machine has been adjusted to a leveled state:
• The water pipe has been connected and the water valve is open:
• The plug has been connected to the power supply and the power switch is off.
• The ambient temperature, water temperature, and pressure of the water supply meet the above requirements.
  2. Startup: turn on the power switch. After power-on. the machine begins to make ice automatically.
  3. For normal operation, please confirm: ✓ There is water in the water trough and no

Operation Instruction

Startup: after proper installation, connect the water source and turn on the power supply, the machine will start working. Please confirm that the machine is operating normally when you turn it on for the first time.
Note: In case of a thunderstorm or not In use for a long time, please disconnect the power and water source!

• Self-check: with power on for the first lime, the ice maker will do a self-check and pump out the remaining water.
• Preparing: after the ice machine is energized, the inlet valve opens and the inlet water will flow in until it reaches the set level; then the ice maker will do defrosting one time. • Ice making: after pre-cooling for 30 seconds. the water pump starts. the water flows through the evaporator smoothly and evenly, the ice cubes are gradually formed in the ice cube tray.
• Ice Harvest: after the ice making process. the water pump is turned off, overflow occurs:
  ✓ The pump is working properly and water is flowing evenly on the evaporator:
  ✓ The compressor is running normally. the temperature of the evaporator and the ice making water is gradually decreasing:
  ✓ For air cooled machine, check the fan is running normally. and there is stable air flow in the inlet and outlet of the ice machine:
  ✓ The ice machine has no abnormal noise:
  ✓ The ice machine has no abnormal vibration;
  ✓ II takes about 10 to 20 minutes to make one batch ice. depending on the ambient temperature and the temperature of the water. The higher the temperature is. the longer the ice making will take:
  ✓ Ice cube can be properly defrosted from the machine.
  the defrosting valve is turned on, and after the hot gas enters into the evaporator for about 1-2 minutes. the ice cubes slides from the evaporator into the storage bin.

Warning: Do not put your hand into the ice storage bin during the ice- falling process to prevent the Ice from hitting your hand!

• Shutdown: The ice maker will stop working when you dick the “onror button on the panel during running process.
• Bin full stop: in the running state, with the storage bin filled to a certain height, the ice sliding board cannot be rebounded or reset because of the block of the freshly produced ice cubes, the ice maker will stop in 40 seconds.
• Repeat Ice-making: when the ice cubes on the ice sliding board are taken away. the ice maker will back to ice making process in a few seconds.
