Warning Messages - Bunn Ultra Technical Training Manual

30 or 25: The left or right number represented is a real time operation number (torque) related to the Thickness set-
ting multiplied by three.
Note: No load (product) on the auger shaft torsion spring during rotation will start from thickness setting multiplied by
three and countdown to zero. If zero is not achieved and a number is represented, this is an indication of a worn tor-
sion spring in the auger shaft.
161° h: The temperature value on the screen can be used to see the possibility of a dirty filter or placement of dis-
penser in a high ambient environment. High temperature reading can prompt messages when temperature reaches
220° or higher.
Note: Temperature is monitored from the temperature sensor clamped onto the refrigeration high side line.

Warning Messages

Clean Filter Message
A monthly counter will automatically show the warning message to clean the condenser filter. If the filter is not
cleaned and the machine detects a rise in temperature, the message will escalate to the next level of cleaning the
filter and eventually will disable the machine from freezing (ice).
Clean Due Today Message
The messages come from the activation of the "Days To Clean" menu. It can be set up as a clean message only or
set as a clean lockout. To reset the Clean Due Today message or lockout, two functions must be performed. Either
power off the dispenser using the I/O (ON/OFF) switch and allow the barrels or cooling drums to warm over 50°F.
Scroll to the Cleaning Guide and perform the cleaning service. The barrels will warm to over 50°F when cleaned with
warm water and the message will disappear.
