USER GUIDE
ICE MAKER OPERATING CYCLES (U-CO29F
MODEL)
NOTE: The refrigeration system operates independently of
the ice maker. This is a new design for U-Line. All other
U-Line ice makers use a double throw control system
where the unit is either in a freeze mode or harvest mode.
In the U-CO29F, the refrigeration system will cycle on and
off depending on the temperature of the freezer. In most
cases, this means the refrigeration system will be
operating during the ice making and harvest modes. If the
freezer control is set too warm, the refrigeration system
may cycle off during ice making mode, slowing the ice
production rate. If this happens, adjust the freezer control
colder.
Freeze Cycle
• Ice maker thermostat (located behind grille) open.
• Freezer control closed and refrigeration system is
operating.
Harvest Cycle - 1
• Ice maker thermostat closed.
• Refrigeration system operating.
• If bin arm is up, the harvest will not initiate.
• Power goes through the bin switch to the ice maker
motor and mold heater.
Harvest Cycle - 2
• Ice maker ejector blades reach 2:00 position and cam
depresses the hold switch.
• Ejector blades stall on ice and ice maker motor
pulsates until mold heater warms and ice releases.
• Refrigeration system operating.
Water Fill Cycle
• Ice maker blades reach approximately 10:00 position
and cam depresses the water fill switch.
• Power to the water valve. Ice maker mold fills.
• Refrigeration system operating.
Eject Cycle
• Ejector blades push ice into bucket and stop at 12:00
position.
• Ice maker temperature control opens.
• Refrigeration system still operating.
