I. Startup

 WARNING

All parts are factory-adjusted. Improper adjustments may adversely affect safety, 
performance, component life, and warranty coverage.

NOTICE

• If the icemaker is turned off, wait for at least 3 minutes before restarting the 

icemaker to prevent damage to the compressor.

• The pump motor is energized continuously when the control switch is in the 

"SERVICE" position.  
• At startup, confirm that all internal and external connections are free of leaks.

Additional Notice for Remote Models

• The icemaker must have power for a minimum of 4 hours prior to startup to 

prevent compressor damage.

1) Open the water supply line shut-off valve(s).
2) Remove the front panel.
3) Move the control switch to the "ICE" position.
4) Replace the front panel in its correct position.
5) Turn on the power supply and allow the icemaker to operate for a total of 10 minutes.
6) Remove the front panel, then move the service switch to the "DRAIN" position. 
7) Replace the front panel in its correct position and allow the icemaker to drain for 

2 minutes.

8) Turn off the power supply. 
9) Remove the front panel, then move the control switch to the "ICE" position. Replace the 

front panel in its correct position.

10) Clean the dispenser unit/ice storage bin liner using a neutral cleaner. Rinse thoroughly 

after cleaning.

11) Turn on the power supply to start the automatic icemaking process.
12) During the first 5 minutes of the freeze cycle, confirm bin control operation by pressing 

and holding the bin control's actuator paddle until the icemaker shuts down. The 
icemaker should shut down in approximately 15 seconds.

13) On water-cooled models, confirm proper condenser drain outlet/return outlet 

temperature as outlined in "II.F.2. Water-Cooled Condenser."
