[k] CANCELING SOFT START
To cancel the “soft start” (3 minute delay), turn on the power supply while pressing the Set
Point Button. The Compressor and Condenser Fan Motor will start at the same time after
0 seconds.
When the soft start is cancelled, the illuminated seven segment LED on the Temperature
Display Window changes to the model setting number. To resume the cabinet temperature
display, press the Set Point Button again or wait for 30 seconds.
Note: If the power supply is turned off while the Compressor is running and immediately
turned back on to cancel the soft start, the high-side and low-side pressures cannot
be equalized, often resulting in Compressor starting failure. Do not cancel the soft
start for at least 2.5 minutes after the power supply is turned off.

between one of the following error codes and the cabinet temperature. See “III. 1. ERROR
