G. Amber Light
During the normal operation, the amber light next to
the PUSH TO FREEZE switch will illuminate after
the freezer has been idle for the preset cycles.
Before drawing product, press the PUSH TO
FREEZE switch. A horzontal status bar on the LCD
display will begin to fill the screen as product
freezes down. Wait until at least six bars are
dirsplayed or the green light is illuminated before
dispensing.
NOTE
If the freezer shuts off and alternating green and
amber lights flash on the control panel, the freezer
is running in the "cab only " mode (both freezing
cylinders are turned off) or the freezer is in an error
condition. Note the display on the LCD screen. If
the screen displays an error, turn the Freezing
Cylinder Off/On switch to the OFF position, correct
the problem and place the Freezing Cylinder Off/
On switch to the ON position. (Refer to Trouble-
shooting in Section 4).
H. Green Light
The green light is used to indicate that the product
has reached the proper consistency and is ready
to be dispensed. The light begins to flash at 98%
of consistency.
I. Clean Switch
The CLEAN switch is a membrane, or "snap"
switch. When the switch is pushed, the freezing
cylinder's refrigeration system will be OFF and the
auger will rotate for cleaning. The CLEAN mes-
sage will display on the LCD screen. When the
switch is pushed again, the auger will stop and the
amber light will flash indicating the freezer is in the
CLEAN mode. To exit the CLEAN mode turn the
Freezing Cylinder Off/On switch to the OFF
position. If the freezer is left in CLEAN for more
than 30 minutes, it will go in error.
J. Drive Motor Overload
The internal drive motor overload will trip if the drive
motor is overloaded. It will reset after approximately
10-12 minutes. If the drive motor continues to trip,
refer to Troubleshooting in Section 4-.
K. Mix Low Light Indicator
A MIX LOW message will appear on the LCD
display to alert the operator of a low mix condition.
The message will display when there is approxi-
mately one gallon of mix left in the mix container or
when one bag of theBCS is empty. When the MIX
LOW message is displayed, refill the container or
replace the bag immediately.
L. Dispense Rate Adjusters
The dispense rate adjuster limits the opening of the
spigot. To adjust product dispense rate, turn the
adjusting knob clockwise for slower flow and counter-
clockwise for faster flow. It takes at least five com-
plete turns of the adjusting knob to make a noticable
difference in the dispense rate.
M. High Head Pressure Cut Out
If the head pressure exceeds 445 PSIG (28 bar) , the
high head pressure cutout will trip. The reset button
can be accessed from the top left corner on the right
side panel of the freezer.
N. Front Door Safety Switch
The front door safety switch prevents the auger from
turning when the front door is removed. The switch
is open when the door is removed and closed when
the door is properly installed.
