SYRUP MOT OR SETUP
TIME: 0.25 SEC
CHOCOLATE
Figure 80
Each peristaltic pump motor must reverse the syrup
flow momentarily when the flow is stopped in order
to eliminate the pressure in the line and close the
duckbill syrup valve. T he reverse time setting for
most thin viscosity syrups is 0.25 seconds. Thick
viscosity syrup may require a slightly longer reverse
time setting (0.26 – 0.32).
Examples: (Triple Thick Shake Settings)
FLAVOR SPEED REVERSE TIME
Chocolate 160 0.28 - 0.32
Strawberry 140 0.26 - 0.30
Vanilla 85 0.25 - 0.28
Optional 100 0.25 - 0.28
If the reverse time setting is too short, pressure
remaining in the line may cause syrup to seep past
the duckbill valve after the shake is dispensed.
When this occurs, the flavoring will carry-over to the
next serving.
If the reverse time setting is too long an air pocket
may form in the syrup line connected to the freezer
door. An air pocket in the line will delay syrup
blending with the frozen mix causing unflavored
product to be dispensed in the bottom of the cup.
Select the AUTO symbol
to increase the reverse
time setting or the OPTIONAL FLAVOR symbol
to decrease the setting. Select the CALIBRATION
symbol
to advance to the motor speed setting
screen for the next flavor.
Enter the settings for the remaining flavors in the
same manner, then select the CALIBRATION
symbol
to return to the Service Menu.
Note: T o save the Syrup Motor Setup settings you
must advance through the screens for each flavor by
selecting the CALIBRATION symbol
. Exiting the
menu option by any other manner will not save the
new settings.
