Figure 11. Operating Controls
WARNING
Hazardous voltage
The Main Freezer Power switch must be placed in the
OFF position when disassembling for cleaning or
servicing. The freezer must be disconnected from
electrical supply before removing any access panel.
Failure to disconnect power before servicing could
result in death or serious injury.
A. Spigot Switch
The Spigot switch will automatically actuate the
auger drive and refrigeration systems when the
spigot is opened to dispense product. When the
spigot is closed, the drive motor and compressor will
remain "on" until the product in the freezing cylinder
reaches the proper consistency.
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.
C. Main Freezer Power Switch
The Main Freezer Power switch is a two position
rocker switch. that supplies power to the freezing
cylinder circuits and the lower cabinet refrigeration
system. When the switch is placed in the ON
position, the lower cabinet refrigeration system will
run until the preset temperature is reached; then
cycle ON and OFF to maintain that temperature.
Power to individual freezing cylinders can then be
controlled with the Freezing cylinder OFF/ON
switches.
D. Cab Off Indicator Light
A flashing light indicates the Main Freezer Power
Switch is in the OFF position, and no refrigeration is
being supplied to the cab. Place the Main Freezer
Power Switch switch in the ON position for cab
refrigeration.
E. Pump Switch
The pump motor switches are the two toggle switches
located in the upper lefthand side of the refrigerated
cab. When a switch is placed in the OFF position, the
pump will not run. When the switch is placed in the
ON position, the pump will run until the preset
pressure is reached, then cycle ON and OFF
as product is drawn to maintain that pressure.
F. 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 motor starts, there is a 3 second
delay before the compressor starts.
