HOW YOUR TUBE-ICE MACHINE WORKS
10/21/01
4-4
When ice bin thermostats are NOT used.
With the selector switch set on either “Auto” or “Cyl”,
the machine will produce cylinder ice. If the switch is changed to “Cru” while the unit is producing
cylinder ice, after the first 5 minutes of a cycle, it will complete the freeze and evacuation of the
cylinder ice before changing to the production of crushed ice. The next cycle will produce crushed
ice.
With the switch set on “Cru” the machine will produce crushed ice. If the switch is changed to
“Auto” or “Cyl” within the first 5 minutes of a cycle, the unit will revert immediately to the
production of cylinder ice.
The selector switch will function as stated above (see FIGURES 6-2 & 9-7).
Starting and stopping of the machine must be controlled by the “Ice” switch (see FIGURE 6-2).
If an alternate bin level control is used, it must be located in a position to stop the machine prior to ice
backing up into the ice chute and jamming cutter.
Crushed Ice Preferred
. A special customized PLC can be programmed and furnished as an option
to produce crushed ice first when the selector switch is in the “Auto” position. This option will still
allow the operator to select “Cyl” or “Cru” ice as desired, but will produce crushed ice and satisfy
that thermostat first then revert to making cylinder ice. Contact your distributor for details.
Single Ice Type.
The machine will contain only one freezer pressure switch (FPS2) and one bin
thermostat (BT2). A selector switch (SS) and reversing relay (R) are not included. The machine will
also be supplied with an ice chute without an ice deflector door assembly (FIGURE 9-12).
Cylinder Ice.
The single ice type machine will be factory adjusted to produce cylinder ice.
Crushed Ice.
To convert a single ice type machine from cylinder ice to crushed ice, only small
modifications need to be made.
•
Move jumper in control panel
•
Adjust freezer pressure switch (FPS2)
See “Converting from cylinder ice to crushed ice”, Section 9, “Service Operations” for details.
