DESCALING AND SANITIZING

Please follow the instructions below when descaling
and sanitizing your machine.

Hold the

CLEAN

button for three seconds to initiate
the automatic descaling sequence. The descaling
sequence begins by harvesting all the ice from
the evaporator. Once the harvest is complete, the
machine will beep and display “Add” indicating it is
time to add cleaning chemicals to the unit.

After the chemicals have been added, the machine
will go through a sequence of rinse and drain cycles
to descale the machine and drain all the descaling
chemicals from the unit. Once complete, the
machine will resume whatever it was doing to prior
to descaling. If the machine was making ice prior
to pressing the
making. If the machine was off before

pressed, it will turn off when descaling is complete.

NOTE: THE DESCALING SEQUENCE CAN BE
CANCELED BY HOLDING THE

CLEAN

BU T T O N

FOR THREE SECONDS.

A full descaling should be performed every six
months. Descaling also involves removing key ice
machine parts and rinsing them and the inside of
the machine with ice machine descaler.

Sanitizing the ice machine is done to remove any
biological contamination that may have occurred.
That process is identical to the descaling process
above except that a sanitizing agent is used in place
of the descaling chemicals.
