INSTALLING YOUR TUBE-ICE MACHINE
10/21/01
3-18
The control panel is electrically connected so that the bin thermostat will stop the machine only upon
the completion of a harvest period.
When both cylinder and crushed ice are produced and separately stored in a divided bin, the control
bulb of thermostat BT1 is placed in the crushed ice section of the storage bin (left side) and the
control bulb of thermostat BT2 is placed in the cylinder ice section (right side of bin).
When the bin does not have a divider, only one thermostat is necessary. The wiring may be modified
to use only one thermostat and bulb (See “With No Divider in Bin”, Section 4 and FIGURE 3-14).
Or install both bulbs--so that the ice contacts both bulbs when the bin is full.

thermostat bulb into the bin, mounting it as illustrated in FIGURE 3-14.
