Changing the 
NNS (Under the 
Counter)
NNS (Non-Nutritive Sweetener) is a BIB 
ingredient located under the counter for 
each Freestyle® dispenser. When NNS is 
empty, the dispenser it serves will be 
unable to pour diet or low calorie 
beverages and those brands will display 
as gray outs on the touch screen. 
1 
  To ensure a BIB is empty, check the 
Crew Dashboard to see if the NNS 
indicator has turned red with a “Sold 
Out” alert. 
2 
  Open the cabinet under the counter 
and replace the NNS using a new 
box from your storage area. 
 
(Follow procedures as shown.)
3 
  Once the new NNS box is installed, 
return to the Crew Dashboard and 
press the red “Sold Out” alert to 
prime and reset.
NOTE: NNS indicator displays a green dot 
when successfully reset.
Release by moving 
locking lever to the 
left. Double check to 
ensure the box is 
empty and remove.
Remove the locking 
collar by pressing the 
tab and rotating 
clockwise. 
Open the new box, 
and remove cap.
 
CAUTION: DO NOT 
Place box onto tray 
 
with the arrows on 
the package facing 
connector, then 
move lever to the 
right to lock.
