HOW YOUR TUBE-ICE MACHINE WORKS
10/21/01
4-3
Dual ice type (crushed and cylinder).
Divider in bin (cylinder and crushed ice separately stored).
With the selector switch on “Auto”,
the machine will automatically produce cylinder ice until the cylinder-ice bin is filled. This action will
open the cylinder ice thermostat switch in the cylinder ice bin and will automatically change the
machine over to crushed ice production--PROVIDED THE CRUSHED ICE BIN IS NOT FULL.
When the crushed ice bin is filled, its thermostat switch opens and stops the machine upon completion
of the harvest cycle and partial pumpdown cycle.
If cylinder ice is removed--during the freeze cycle of the crushed ice operation and the cylinder ice bin
thermostat switch closes within five minutes of that cycle, the machine will revert immediately to
cylinder ice production.
If, when producing cylinder ice, the thermostat switch for cylinder ice should open within the first five
minutes of that cycle, the machine will immediately revert to crushed ice production. The selection of
cylinder or crushed ice can be changed for that cycle only within the first five minutes of the freezing
cycle. Note that the “R” (reversing relay) is not energized when making cylinder ice.
The machine will never stop by action of the bin thermostat during any freezing operation. It will
always complete the evacuation and discharge of all the ice and completion of a partial pumpdown
cycle regardless of the causes which open either thermostat switch.
See FIGURE 3-14, “Illustration of the Bin Thermostat Bulb Installation”.
With no divider in bin (producing only ONE type ice).
When there is no partition in the bin for
separating cylinder and crushed ice, you need use only one bin thermostat and bulb. By connecting
wires #25 and #26 together on the same thermostat terminal and installing that thermostat bulb in the
bin, you will have the other thermostat as a spare. You will still be able to produce cylinder or
crushed ice, whichever is desired. The deflector door assembly and chute deflector may be removed
if the bin has no divider (see FIGURE 9-14).
See FIGURE 3-15, “Wiring for Single Thermostat Operation”.
Ice Selector Switch, FIGURES 6-2 & 9-7
. When the selector switch is set on either “Auto” or
“Cyl”, the machine will produce cylinder ice until the bin is filled and the thermostat switch opens,
shutting down production at the completion of the thaw mode and partial pumpdown cycle. If the
selector switch is changed to “Cru” after the unit has started a cylinder ice freeze and five minutes has
lapsed, it will complete the freeze and evacuation of the cylinder ice BEFORE changing to the
production of crushed ice. If five minutes has not lapsed, it will revert to crushed ice immediately.
With the selector switch set on “Cru”, the machine will produce crushed ice until the bin is filled and
the thermostat switch opens. It will then shut down at the completion of the thawing period and
partial pumpdown cycle. If the switch is changed to “Auto” or “Cyl” within five minutes of the
machine starting crushed ice freeze, it will switch immediately to the production of cylinder ice.
