i) Refill Counter (S2 dip switch 3)
Do not adjust. This must be left in the factory default position or the unit will not operate
properly. The refill counter is deactivated before shipping.
j) Harvest Completion Detection Control (S2 dip switch 4)
Do not adjust. This must be left in the factory default position or the unit will not operate
properly.
It is deactivated on the KMD-210AB-HC.
When activated, this control determines whether ice remains on the evaporator at the end of
a harvest cycle and at the beginning of a freeze cycle. If ice drops and activates the bin
control switch in the last 10 seconds of a harvest cycle, the control determines that ice still
remains on the evaporator and extends the harvest cycle for 30 seconds. If the bin control
switch is activated at the beginning of a freeze cycle, the control determines that ice still
remains on the evaporator and starts a harvest cycle after the minimum freeze cycle time
has passed.

k) Overfreeze Detection Control (S2 dip switch 5)
Do not adjust. This must be left in the factory default position or the unit will not operate
properly.
It is deactivated on the
KMD-210AB-HC.
When activated, the thermistor detects the temperature of the evaporator outlet to find
overfreeze in a harvest cycle and at the beginning of a freeze cycle. If the difference
between the maximum temperature after the water saver timer starts counting and the
temperature at the end of a harvest cycle is 4K or more and if the temperature at the end of
a harvest cycle is 48°F (9°C) or less, the harvest cycle is extended for 30 seconds. If the
difference between the temperature at the beginning of a freeze cycle and the minimum
temperature after 30 seconds in the freeze cycle is 2.5K or more and less than 3.5K, the
next harvest cycle is extended for 30 seconds. If the above conditions occur in succession,
the number of occurrence times 30 seconds will be added to the harvest cycle time. If the
above temperature difference is 3.5K or more, the freeze cycle ends after the minimum
freeze cycle time and a harvest cycle starts. If the evaporator outlet temperature is more
than 3.5°C but not more than 5°C at the end of harvest cycle, the harvest cycle is extended
for 50 seconds before moving on to the freeze cycle. If the evaporator outlet temperature is
3.5°C or less, another harvest cycle starts. The harvest cycle does not repeat more than
three times. The freeze cycle starts even if the evaporator outlet temperature is 3.5°C or less
at the end of the third harvest cycle.
