HOLDING CABINET—NORMAL OPERATION (CONT)
CAUTION:
HOT SURFACE
Inner surfaces of the unit
will be very hot during and
after operation.
Avoid touching the cabinet
when loading or removing
product.
LOW TEMPERATURE ALARM
The cabinet is equipped with a low temperature alarm feature. When
the alarm is active, the temperature display will indicate “LO” and then
“TEMP” and the audible alarm will sound. To silence the alarm,
press the “alarm off” button. If the actual temperature is still below the
low temperature alarm set point after 5 minutes, the alarm will sound
again.
This alarm can be triggered by the door being left open, loading of
product that is much colder than the temperature set point in the cabi-
net or due to a malfunction of the heating system.
To change the low temperature alarm set point, press and hold the
“alarm off” button while adjusting the temperature set point knob to
the new desired value. Due to food safety concerns, the low tem-
perature alarm should not be set below 140 degrees F. After 3
seconds, the controller will accept the new set point. The new value
will be stored in the controller memory until the next time the value is
changed.
The audible alarm for low cabinet temperature can be turned off.
The factory default is ON. To enter into the adjustment mode, push
in and hold the “alarm off” button until the alarm sounds. The display
will read either (ON or OFF). To change the status, push the temper-
ature knob, which will function as a toggle switch to select between
ON or OFF. After 10 seconds, the controller will accept the desired
audible alarm function (either ON or OFF). If OFF is selected, the
temperature display will still indicate “LO” and “TEMP” if the low temp
alarm is tripped.
Factory default setpoints:
- temperature: 160ºF
- low temp alarm: 140ºF
Operating ranges:
- temp alarm: 80ºF-180ºF
- air temp: 90ºF-200ºF
