Icemaker is operated in accordance to the following process
3.4 Operation Cycle
3.5 Safety
(1) Water Supplying Cycle
Once power is on, water supply valve opens to fill the water tank with water required.
(2) Harvesting Cycle
To remove ice made on the evaporator, water flow stops and it becomes hot. Then, ice is released from
the evaporator to storage container. Once temperature sensor detects a certain temperature, freezing
cycle begins. Water is continued to be supplied during the harvesting cycle.
(3) Freezing Cycle
This is the process of making an ice. Water is supplied to the surface of evaporator and it becomes cold.
As water keep circulating, more and more iceis made. This process is repeated until water level sensor
reaches low. Once it becomes the low level, ice harvesting starts.
(4) Drainage Cycle
This occurs residue or impurities in the water tank while repeating the process of freezing and
harvesting cycles. Using ice machine for a long time without any drain may cause damage.
After a certain number of cycles, drain leftover water in the water tank completely by using pump.
(1) Maximum freezing time - 60min
To protect the icemaker, maximum freezing time is set to 60 minutes. When freezing cycle goes over 60
minutes, it turns into harvesting cycle. Also for the second freezing cycle, if time goes over 60 minutes,
machine halts and shows error code (E1) on the control panel with a beep sound.
(2) Maximum harvesting time - 20min
The maximum harvesting time is 20 minutes. If time goes over 20 minutes, it automatically turns into
freezing cycle. Also in the second harvesting cycle, if time goes over 20 minutes, error code (E2) is
shown on the control panel with a beep sound.
(3) HighTemperature safety
If temperature outside the evaporator during freezing cycles goes over 140°F(60°C), machine stops to
protect the cycle and error code (E3) is shown on the control panel.
(4) Low water safety
For protection of water pump, if water level is low after harvesting cycle, machine halts and error code (E5)
is shown on the control panel.
