5. Usage
5-7. Understanding the ice making process and operation
When the water level in the ambient water tank reaches to specific level, it starts to remove all the remaining ice on
the evaporator. This action is done when power is newly supplied to the unit.
The compressor and ice making pump operate in order to make cold water.
(The cold water production process automatically operates according to designated programming.)
Cold water operation: Cold water is made by process of spraying water to evaporator.
Water temperature in the cold water tank is automatically detected by the sensor, and if it
drops below the set temperature, then the cold water operation will automatically stop.
If cold water production is done, ice making get started in accordance with the process of Ice forming and Ice
harvesting action.
Ice forming action: Spray cold water to the evaporator for given time.
Ice harvesting action: Supply heat to the evaporator to remove ice from the evaporator.
When the ice storage is full, the ice level sensor automatically sends the signal of stopping ice making process.
If ice in the storage is not used for long periods of time, it may melt, and small pieces of ice can be served during ice
dispensing.
TDS(Total Dissolved Solid) of ice may increase slightly according to the environment in which the ice is made.
The lower room temperature is, the shorter the ice making process will take and the higher room
temperature is, the longer the ice making process will do.
Do not install or use the unit in temperatures below 32 (0 ) or above 104 (40 ).
Ice making system of the unit starts and operates to make ice automatically according to
program set after power is ON.
Push the center of water tray until "clattering" sound.
