Control Switches

There is a front on and off switch, located in the top
center of the louvers. Switching this switch Off will
immediately stop the machine. Switching it back on
will cause the machine to start in a timed harvest
cycle.
The controller also has on and off switches, which
can also switch the machine on and off, but their
operation is different:
To switch the machine OFF, push and release the
Off button. The machine will shut off at the end of
the next cycle. To shut the machine off
immediately, push and hold the Off button for 3
seconds.
To switch the machine ON, push and release the
On button. The machine will go through a start up
process and then resume ice making.
Note: Front On/Off Switch discontinued February
