ICE MAKING SEQUENCE
Your True Ice™ machine will produce one batch 
of ice (24 cubes) roughly every 30 minutes. The 
following steps occur during ice making:
HARVEST / FILL – The ice machine always begins 
in the harvest mode. Display will read “HAr.” During 
harvest all the ice cubes are melted free from the 
evaporator. The ice machine does this by warming 
up the evaporator with warm refrigerant. During 
harvest the ice machine will also fill with water and 
drain off any excess/residual ice making water. At 
start up the harvest will last two minutes.
ICE MAKING – During ice making the display will 
read “ICE.” Water is sprayed into the inverted ice 
cups while the evaporator is cooled. This causes 
ultra-clear ice cubes to form inside each ice cup. 
The compressor, condenser fan and water pump 
all operate during this mode. The ice machine 
automatically adjusts the freeze time based on the 
ambient air temperature.
FULL BIN – The ice machine shuts off automatically 
when the bin is full of ice. A full bin is detected 
when ice touches the bin thermostat tube. The 
machine will come back on when ice is no longer in 
contact with the thermostat tube.
