C. FRONT DOOR SAFETY SWITCH (BOTH SIDES)
The front door safety switch prevents the auger from turn-
ing when the front door is removed. The switch is open
when the door is removed and closed when the door is
properly installed.
D. DRIVE MOTOR OVERLOAD (BOTH SIDES)
The drive motor overload will trip if the drive motor is
overloaded. Single phase machines have an internal
overload and three phase machines have an external
overload. The overload will reset after approximately 10-
12 minutes. If the drive motor continues to trip, refer to
the Troubleshooting Section.
E. DISPENSE RATE ADJUSTOR (LEFT SIDE)
The dispense rate adjustor is located under the header
panel, to the immediate right of each spigot handle. Turning
the knob counterclockwise will decrease the dispense rate.
F. CLEAN/OFF/SERVE SWITCH (LEFT SIDE)
The CLEAN-OFF-SERVE switch is a three position toggle
switch used to control the operation of the refrigeration
system and auger. When the switch is placed in the
CLEAN position, the refrigeration system will be off and
auger will rotate for cleaning. When the switch is placed
in the OFF position, the refrigeration system and auger
will not operate. When the switch is placed in the SERVE
position, the refrigeration system and auger will operate
automatically. The switch should be placed in the SERVE
position for normal operation.
G. STANDBY/SERVE SWITCH (LEFT SIDE)
The standby/serve switch is a two position toggle switch.
When the switch is placed in the standby position the
machine will cycle to maintain a temperature below 41°F
(-15°C). When the switch is in the Serve position the ma-
chine will cycle to maintain a servable product.
H. FREEZING SWITCH (LEFT SIDE)
The freezing switch is a two position toggle switch. When
the switch is placed in the MAXIMUM position the machine
will be forced to run 30 seconds after the spigot is closed
if the temperature control is satisfi ed.
I. LOW MIX LIGHT (LEFT SIDE)
The low mix light will illuminate when the liquid level in
the mix container drops below the mix low level indicator.
(To adjust the indicator see Section 2.6 C.)
J. MAIN FREEZER POWER SWITCH (RIGHT SIDE)
The Main Freezer Power switch is a two position rocker
switch that supplies power to the IntelliTec control, the
right freezing cylinder circuits and the cabinet refrigeration
system. When the switch is placed in the ON position,
the cabinet refrigeration system will run until the preset
temperature is reached; then it will cycle ON and OFF to
maintain that temperature. Power to the right side freezing
cylinder can then be controlled with the Freezing Cylinder
OFF/ON switch.
K. FREEZING CYLINDER OFF/ON SWITCH (RIGHT
SIDE)
The Freezing Cylinder OFF/ON switch is a two position
toggle switch used to supply power to the right freezing
cylinder control circuit. When the switch is in the OFF
position, the freezing cylinder’s refrigeration system and
auger will not operate. When the switch is in the ON posi-
tion, the machine will be operational.
L. BLENDER POWER OFF/ON AND CIRCUIT BREAKER
SWITCH (RIGHT SIDE - SU444 ONLY)
The Blender Power Off/On and Circuit Breaker switch is
a two position toggle switch used to supply power to the
blender. When the switch is in the OFF position, there is
no power to the blender. When the switch is in the ON
position, the blender will operate any time the spigot
handle is pushed to the right. This switch also serves as
a circuit breaker to interrupt power if the rotation of the
blender agitator becomes hindered.
M. CAB OFF INDICATOR LIGHT (RIGHT SIDE)
A fl ashing light indicates the Main Freezer Power Switch
is in the OFF position; no refrigeration is being supplied
to the cab. Place the Main Freezer Power switch in the
ON position for cab refrigeration.
N. PUSH TO FREEZE BUTTON (RIGHT SIDE)
The PUSH TO FREEZE button is a snap switch used to
initiate “Serve Mode”.
NOTE
After the PUSH TO FREEZE button is pressed,
the drive motor starts. After a 3-second delay, the
compressor will start.
O. LEDS (RIGHT SIDE)
The membrane switch (touchpad) features two lights: a
green LED and an amber LED. The green LED is lit dur-
ing “Serve Mode”. During freeze down, it is not lit. When
product consistency approaches 75% in the freezing
cylinder, the green LED fl ashes. The amber LED is on
during all other modes. Both LEDs alternatively fl ash if
an error occurs or if the freezing cylinder is off.
P. CLEAN BUTTON (RIGHT SIDE)
The CLEAN button is a snap switch. When the button is
pressed, the freezing cycle stops and the drive motor will
start. A CLEAN message will display on the LCD screen
along with a 5-minute countdown timer. To exit the CLEAN
mode, turn the Freezing Cylinder OFF/ON switch to the
OFF position or press the CLEAN button again. If the
machine is left in CLEAN for more than 20 minutes, an
error code (E4) will be displayed on the display panel.
Place the Freezing Cylinder OFF/ON switch in the OFF
position and back in the ON position to clear this error.
Q. MIX LOW LIGHT INDICATOR (RIGHT SIDE)
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 approximately one gallon of mix
left in the mix container. When the MIX LOW message is
displayed, refi ll the container or replace a bag immediately.
