DOOR OPEN will appear in the display whenever the unit is in operation and the door is opened.
When the date and time (only) is showing in the display, this message will not appear when the door is
opened. If the Quickchiller door is opened during any running chill or freeze cycle, the fans will
disengage and the compressor will cycle down. When the door is closed, the fans and compressor will
reengage and the chiller will begin operating at the point of interruption.
The Quickchiller will only trigger an automatic defrost cycle during the refrigerated Hold Temp mode.
If the chiller is in any other mode when the 6-hour Fan Timer limit plus one additional hour has elapsed, the
display will indicate a warning message DEFROST OVERDUE and the control will produce an audible
signal every 10 seconds until a defrost is conducted.
The audible signal can be silenced by pressing the PROGRAM key.
NOTE: If the Quickchiller door is opened during any running chill or freeze cycle, the fans will disengage
and the compressor will cycle down. When the door is closed, the fans and compressor will
reengage and the chiller will begin operating at the point of interruption.
POWER WAS OFF will appear in the display whenever operation is interrupted by a power outage. The
control will produce an audible signal every 10 seconds and the display will indicate the amount of time the
power was off. If consecutive power outages occur before the first outage has been acknowledged, the
control will accumulate the total amount of outage time up to a period of 23 hours. After a period of 24
hours, accumulated time will be shown as greater than 24 hours, i.e., >24.
Press the PROGRAM key START/STOP key, or POWER key to clear the display and stop the audible signal.
