B. Freezing Cylinder Off-On switch
The Freezing Cylinder Off-On switches are two
position toggle switches used to supply power to the
left or right freezing cylinder control circuit. When
the switch is in the OFF position, the refrigeration
system and auger will not operate. When the switch
is in the ON position, the freezer can be run in the
freezing mode or cleaning mode. The freezer will be
in the sleep mode until a switch is activated.
NOTE
The control on the left side of the freezer also
controls the refrigeration of both mix hoppers.
The left Freezing Cylinder Off-On switch must
be in the ON position any time there is mix in
the freezer, even if the left cylinder is not being
used.
C. Push To Freeze Switch
The PUSH TO FREEZE switch is a membrane or
"snap" switch used to start the freezing cycle.
During initial freeze down, the The Main Freezer
Power switch and Freezing Cylinder Off-On switch
are placed in the ON position. Next, the PUSH TO
FREEZE switch is pressed and held until the drive
motor and compressor turn on.
NOTE
After the auger drive motor starts, there is a 3
second delay before the compressor starts.
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 Freez-
ing Cylinder Off/On switch to the ON position.
(Refer to Troubleshooting 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 into an error mode. See
Section 4 regarding errors.
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 hopper. When
the MIX LOW message is displayed, refill the
hopper 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 complete
turns of the adjusting knob to make a noticable
difference in the dispense rate.
M. High Head Pressure Cut Out (water cooled
models only)
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.
