U-Line 2175WCOL Manuale Utente

• Neither ice maker relay is energized.
• Unit is cooling down to 15°F set-point.
• The unit may cycle on and off as the ice maker is pulling 

down to maintain the proper refrigerator/freezer 
temperatures.

• The minimum freeze time as permitted by the board is 20 

minutes (CO2175F) or 75 minutes (CO2175DWR).

• Relay 6 is energized for 30 seconds and relay 7 is energized 

for 10 minutes. The bin arm must be fully lowered and the 
lower drawer closed for this cycle to begin.

• The lower drawer must remain closed for the cycle to 

continue. In the event that it is opened the timers will hold 
until the drawer is closed. At that time they will resume the 
cycle. If the unit has a door rather than a drawer it is not 
effected.

• Relay 6 is now off and the ice maker is powered completely 

by relay 7. This occurs at approximately the 2 o'clock 
position.

• Ejector blades stall on the ice until the heater releases it 

from the mold.

• This cycle will last a few minutes.

• At about the 10 o'clock setting the water valve is energized 

for about 7 seconds to refill the mold.

• At the conclusion of the cycle the blades stop at the 12 

o'clock position.

• Following the water fill relay 7 remains energized for the 

balance of the 10 minutes that it needs to remain on.

• The bin arm is in the UP position, either held in place by the 

ice or manually raised. The board continues to signal the ice 
maker to harvest so relays 6 and 7 will energize; however, 
with the arm up the cycle will not begin.

• The unit is equipped with a four-minute compressor off 

cycle.

• The controller is designed to be able to show and set the 

refrigerator set-point. Based on this input the controller 
tries to maintain the perfect balance of refrigeration to keep 
the refrigerator and freezer at acceptable temperatures. For 
this reason the refrigerator temperature may fluctuate from 
34°F to 40°F depending on the freezer load. The freezer will 
also float in a -10 to +10 range depending on the 
refrigerator load and usage.

• The ice harvest will be initiated when the ice maker 

temperature drops to 15°F. Through a built-in timer the ice 
maker can only harvest once every 20 minutes (for 
CO2175F) or 75 minutes (CO2175DWR) at a maximum so 
if the temperature is at 15°F it will not necessarily cycle 
depending on when the previous cycle had occurred.

• The drain pan heater will energize five minutes before and 

after the hot gas portion of the defrost cycle (not on 
CO2175DWR). This time is not included in the defrost total 
length.

• If the unit is turned off while the ice maker is in a harvest 

mode, the display will flash OFF while the ice is harvesting 
— up to 10 minutes.
