Control Switches
There are two control switches located at the top left
corner of the upper front panel, behind the illuminated
display. The left switch controls the two freezing cylinders
on the left side of the unit. The right switch controls the
two freezing cylinders on the right side of the unit. When
placed in the ON position, these control switches allow
SLUSHTECH operation.
Liquid Crystal Displays
There are two liquid crystal displays (LCDs) located on
the upper front panel behind the illuminated display. The
two LCDs display information for the two freezing
cylinders located directly beneath them. These pairs of
freezing cylinders are each labeled left and right per
LCD.
The LCDs show the current operating mode of the
freezing cylinders. They also indicate whether there is
enough syrup, CO
2
, and water being supplied to the
freezer. If an error in the machine operation occurs, a
warning tone will sound and the word FAULT will flash on
the third line of the display.
Operational Mode Displays
The screens below illustrate the operational mode
information displayed during normal operation. The two
LCDs display information corresponding to the two
freezing cylinders located directly beneath them. These
pairs of freezing cylinders are each labeled left and right
per LCD.
When the unit is plugged into the wall receptacle and the
control switch is in the ON position, this screen appears.
This display will remain on the LCD for 60 seconds
unless a key is pressed. If any key is pressed (or 60
seconds pass), the next screen appears.
Note: Syrup, CO
2
, and water are satisfied.
Pressing the AUTO (- ->) keys for each freezing
cylinder will display this screen.
Line 1 indicates the operating mode for each freezing
cylinder.
Line 2 indicates the status of the syrup systems in
each freezing cylinder. As long as syrup is available,
the word OK will appear on the LCD. When the syrup
supply is insufficient, the word OUT will flash on the
LCD. The same rules apply to the fourth line, which
indicates the status of the CO
2
and the H
2
O.
The third line of this display is a fault indicator. If an
error in machine operation occurs, the word FAULT
will be displayed on the LCD.
Note: Repeat all information and programming pro-
cedures for each individual control from the left to the
right.
